The purpose of the current research is to identify the needs of the management structure of medical centers-hospitals in order to compensate for the damages caused by the fight against Covid-19.

This study is applied in terms of purpose and qualitative in terms of research method, and by using semi-structured interviews with 19 experts who were selected through purposive sampling, effective policies on the management structure of medical centers were identified and were categorized. The data of this section were categorized and analyzed using the three-step open, central and selective coding method. The validity of the categories and themes obtained using experts' confirmation and the reliability using the open test method were found to be 83%.

Experimentation and data analysis of the obtained data led to the formation of 179 subcategories, 43 categories and 8 main themes. During this research, 8 factors of social support of the organization, motivational measures, behavioral measures, financial and welfare measures, open communication, systems Management, organizational policies and human resource policies were selected as the main themes of the research.

Based on the results of qualitative data coding, the democratic style of management and the increase of welfare services were selected as the key categories of the management structure of medical centers due to frequent repetition among the codes received, and based on the number of repetitions of the received codes, the themes of welfare services with The coefficient of 0.172, human resources policies with the coefficient of 0.152 and motivational solutions with the coefficient of 0.148 took the first to third ranks, respectively.

 This study was aimed to investigate the principles and foundations of passive defense, study the types of drinking water storage tanks, identify threats in urban water tanks and prioritize passive defense measures to reduce water tank threats.

 In this study, in order to identify threats in the field of drinking water storage tanks and identify hazards and risk assessment, a combination of Delphi and FEMA methods was used. Moreover, AHP hierarchical analysis was adopted in order to prioritize the types of tanks from the passive defense criteria point of view. Ethical considerations were observed in all stages of the study.

 According to experts, important threats with a high destructive effect in the field of water storage resources included "chemical and biological contaminants" that can endanger the health of water and consumers. Indeed, “air and missile bombings”, "fixed suicide bombings" and "individuals and vehicles" can cause the destruction of reservoir structures and disrupt water supply operations. Moreover, threats related to psychological warfare and soft warfare, including "rumors of water pollution", "psychological operations and personnel evacuation", "process sabotage" and "cyber-attacks" could result in chaos in the society. Accordingly, based on the aggregation of experts' opinions and the points given to water reservoirs in terms of exposure to threats, buried ground reservoir with a score of 0.386, semi-buried ground reservoir with a score of 0.246, elevated reservoir with a score of 0.225 and ground reservoir with a score of 0.143 were respectively prioritized for use as urban water storage tanks.

 According to the results of this study, it is suggested to avoid the implementation of visible water reservoirs, and if possible, the reservoirs should be designed and implemented as buried. If it is not economically justified, the reservoir should be semi-buried with embankment and necessary modifications to the structure. Implement and finally use passive defense measures including camouflage, deception, etc. Evaluation of reservoirs in Sari city showed that the condition of these facilities is not favorable in terms of passive defense requirements, especially in rural areas and small reservoirs.

The purpose of the present study is to identify the compensation strategies for dealing with the covid-19 pandemic among the medical staff.

The research method is exploratory in terms of mixed type and has been done in two parts, qualitative and quantitative. In the qualitative part, through thematic analysis method and using semi-structured interviews with 19 experts who were selected through purposive sampling, policies affecting the management structure of medical centers were identified and categorized. The data of this section were categorized and analyzed using the open, central and selective three-stage coding method. In order to comment on each of the obtained dimensions and rank them, at this stage, the obtained data were tested using the analysis hierarchy process (AHP) using the geometric mean method.

During this research, 179 sub-themes were categorized in the form of 43 main themes and 8 categories based on the results of calculating the final weight of the special vector, the categories of welfare services with a coefficient of 0.172, human resources policies with a coefficient of 0.152 and motivational solutions with a coefficient of 0.148 They ranked first to third respectively, followed by behavioral measures with a coefficient of 0.120, management solutions with a coefficient of 0.108, organizational solutions with a coefficient of 0.107, open communication with a coefficient of 0.103 and social support of the organization with a coefficient of 0.091 respectively. were ranked

The results of the hierarchical analysis test and calculating the geometric mean of indicators show that the main themes of democratic management styles, increasing the level of motivation of the treatment staff, implementing fun programs for members and their families, increasing financial support, in Prioritizing the physical health of the treatment staff, increasing the welfare services for the treatment staff, implementing support pol

After the policies are formulated and approved, they are communicated to the managers for implementation. Several factors lead to the failure of health system policies. In this research, these factors have been identified and ranked.

This was an applied research, and in terms of strategy, it was a survey. The research community consisted of 21 experts in the field of health in the Ministry of Health and universities of medical sciences, who were selected through random and targeted sampling. The tools of data collection were interviews and questionnaires, and to analyze data, Failure Modes and Effects Analysis (FMEA) and Analytical Hierarchy Process (AHP) were used.

In this research, 4 dimensions of failure factors regarding the implementation of the health system policy were identified, including governance, management, environmental and financial resources, and 23 components of the mentioned dimensions were identified. Moreover, the most important identified failure factors through AHP and FMEA were prioritized and evaluated.

Knowledge of failure factors can help to improve the capacity of the implementation of health system policies.

: Site selection is an important and necessary issue in waste management especially in fast-growing regions. Due to the landfill is a common solution for the final disposal of municipal solid waste in Iran, this study was carried out for MSW landfill site selection of Songhor Township by combining the geographic information systems (GIS), the analytical hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

In the current research, ArcGIS 10.2 software and its extensions were used as the GIS tool since there is able to perform suitability analysis using multi-criteria evaluation. Also, to identify appropriate landfill areas in the Songhor Township, eleven criteria including slope, geology, hydrology, fault, drainages, distance from transportation routes and rails, distance from protected areas, land use, population areas, distance from groundwater resources and distance from urban areas were evaluated. Then a final map was generated which identified the suitability regions for MSW landfill sites establishment.

Based on the results obtained, 4.2% of the study area was most suitable, 33% was suitable, 17.8% was poorly suitable, and 45% was unsuitable for sanitary disposal of solid wastes of Songhor Township.

Since the AHP has relative ease of handling multiple criteria, and on the other hand, has potential to easy understand and effective handling of both qualitative and quantitative parameters, therefore, use of AHP is suggested as an efficient method to prioritization of suitable areas for landfill site selection. In other words, the AHP is a powerful tool for solving complicated problems that may have interactions and correlations among multiple objectives.

The issue of social harms and their prevalence among adolescents has become one of the main concerns of families, health system, education and society. The aim of this study was to identify and rank the relationship to high-risk behaviors among students based on the method of hierarchical analysis.

This research was conducted in a survey method on 60 adolescents aged 19-14 years and 60 knowledgeable people in the field of social injuries, including (principals, counselors and teachers) in secondary schools in the 4th district of Karaj in 1399. Is. Sampling was a multi-stage method and data were collected using a pairwise comparison questionnaire and a checklist of demographic-social characteristics and analyzed using Excel software.

Respondents were equally 50% male and 50% female. Male adolescents are exposed to high-risk party and friendship behaviors with 34%, movies and cyberspace with 19%, industrial drug addiction with 18%, light drug addiction with 17% and violence with 12%, respectively. Female adolescents are also exposed to high-risk party and friendship behaviors with 43%, movies and cyberspace with 25%, industrial drug addiction with 17%, light drug addiction with 10% and violence with 5%, respectively. Also, based on gender, the vulnerability of girls is 12% higher than boys.

The results of pairwise analysis of the findings indicate that the prevalence of high-risk behaviors among girls and boys follows a similar pattern and the priority of injuries is the same, but the prevalence of each injury is based on gender. Is different. Therefore, planning to prevent social harm is considered an important necessity for people exposed to high-risk behaviors.

With increasing life expectancy, aging in Iran becomes more feminine. This study aimed to prioritize the criteria affecting the health of Iranian elderly women.

 In this descriptive-analytical study, factors affecting the health of the elderly women, with the opinion of 20 health-policy and health services management experts employed in governmental and non-governmental organizations, were approved. In the second phase, the weight and rank of these criteria were calculated and analyzed using Hierarchical Analysis Process. Excel software was used to analyze data.

 The analysis showed that the individual factor is the most important in terms of factors affecting the health of elderly women. In terms of the type of interventions, the provision of preventive health services, in terms of decision-making, executive interventions at the queue level, in terms of planning, integrated approach, and continuous planning with the participation of public and private sectors were ranked first.

 Given the influence of the previous periods of life on healthy elderly, decision-makers should prioritize preventive services in all periods of life regarding age and gender context. Interventions should be presented with an integrated approach with continuous planning at the levels of government, organization, and queue, as well as with the participation of both public and private sectors. The existence of an information management system, supervision, and evaluation, provides the ground for continuous feedback and improvement of programs. Therefore, it is recommended that the government play a more significant role in ensuring the health of the elderly.

Today, the medical tourism market has been raised as one of the revenue industries in the world. In the tourism industry, factors have a direct and important impact on boom and expansion that causes some countries to become a medical tourism pole. This study aimed at prioritizing factors related to the absorption of medical tourists in Yazd City, Iran.

In the first step, using the keywords such as "medical tourism, effective factors and absorption factors", Web of Science, PubMed, Scopus, ScienceDirect, Google Scholar, Scientific Information Database (SID), Magiran, Medlib, Civilica, and Irandoc were reviewed, and related factors with the absorption of tourists were extracted; and in the second stage, using the hierarchical analysis model, by the research community consisting medical tourists and experts in this area, these factors were prioritized.

Factors were identified in the two themes, seven subthemes, and 27 items; among them, the subtheme of the quality of health services, and item of the quality of the treatment staff had the most importance and priority from the viewpoint of medical tourists and experts in this area.

One of the ways to increase tourists attracting and influencing tourists to choose Iran as a destination country, is to increase the quality of services, especially medical services, along with reducing costs, and making them competitive.

The provision of medical services and the distribution of agonist drugs in substance abuse treatment centers has led to a lack of attention to patients' treatment plans and a greater focus on drug distribution. In order to separate health and pharmaceutical services that are provided for opioid addicts in drug addiction treatment centers, a study has been designed with the aim of locating the selected pharmacy for the distribution of agonist drugs in District 21 of Tehran Municipality with a spatial approach.

This applied research is a descriptive-analytical method. The spatial and descriptive data were collected from the municipality organization and treatment and food and medicine departments of Iran University of Medical Sciences and Health Services and they were analyzed using ArcGIS software. Distribution of pharmacies and drug addiction treatment centers in the study area, locating the appropriate areas, and locating the selected pharmacy were studied by using the kernel density estimation functions, hierarchical analysis, and location model - allocation in two regional and district modes with maximum coverage of drug addiction treatment centers, respectively and analyzed using SPSS software and t-test. 

This study shows that the distribution of pharmacies and population in different regions of the study area is commensurate. Based on the results of locating using hierarchical analysis method, all pharmacies in the study area are appropriate to be the pharmacy for distributing the agonist drugs, and the results of the location model – allocation shows that the average time, and distance to access to the selected district pharmacy is 17 minutes and 5.9 km, respectively and for the regional pharmacy is 2 minutes and 0.7 km, respectively. 

Separation of medical services and distribution of agonist drugs is essential. The findings of this study indicate that the distribution of agonist drugs through selected regional pharmacies increases access to medicine and the satisfaction of patients.

Due to the legal necessity of changing the approach of universities from traditional budgeting into the operational budgeting system, it should be noted that this method of budgeting is associated with challenges. The aim of this study was to evaluate the feasibility and prioritization of operational budgeting dimensions in a military medical university.
Materials &

This descriptive-analytical and cross-sectional study was conducted in 2020 in two stages. In the first stage, 68 managers, staff and experts of the deputy for Planning and Finance of a Military Medical Sciences university were enrolled by census method. In the second stage, 10 experts were purposefully included in the study. Data collection tool was two valid and reliable questionnaires. Data were analyzed using t-test and SPSS software in the first stage and using AHP approach and Expert Choice software in the second stage.

The average overall score and the score for each of the dimensions of ability, authority and acceptance of operational budgeting was 2.3, 2.39, 2.38 and 2.31, respectively which was at an undesirable level (P< 0.05). Also, dimensions of the ability with a weight of 0.547, acceptance with a weight of 0.244 and authority with a weight of 0.209 had the highest weight and importance in the implementation of the operational budgeting system, respectively.

Based on the results, it is necessary to pay attention to the three main dimensions of ability, authority and acceptance in implementing operational budgeting in the study population.

 The global outbreak of the COVID-19 in 2019, and the high mortality rate of the disease call for decision-making and finding a solution to control its spread. One of the most effective ways is to use the COVID-19 vaccine. Due to the limited supply of corona vaccines, the distribution of this vaccine is generally prioritized and allocated among individuals.

 In this descriptive correlational study, GIS, AHP tools, and fuzzy logic were used to achieve the goal of prioritizing and allocating corona vaccine to the neighborhoods in Mashhad. Neighborhoods' prioritization was analyzed in four scenarios including: AHP, WHO guideline, guideline of the Ministry of Health and Medical Education of Iran, and localized collective wisdom.

 The output of neighborhood prioritization of the four mentioned scenarios has been specified in five classes. In the AHP scenario, the lowest percentage (8.89%), and in the localized collective wisdom , the highest percentage (42.22%) was allocated to the neighborhoods with the first priority. Regarding spatial distribution, only in the first scenario, some kind of order was observed. Furthermore, there is generally no high correlation between the results , and only the scenario of the Ministry of Health and Medical Education and the localized collective wisdom presented a correlation of 0.82.

 Considering the COVID-19 vaccine shortage, spatial allocation based on the presented guidelines is a reliable method which can meet the basic criteria for allocating the limited treatment resources, and 180 neighborhoods throughout Mashhad were identified and prioritized with different scenarios which can assist the decision-makers.

New concepts in the field of planning and design for healthcare centers are noteworthy. One of the types of healthcare centers which was brought up and emphasized in terms of efficiency in recent years is micro-hospitals. Considering the ability of micro-hospitals to provide effective availability of healthcare services, elicitation and prioritization of related factors in establishment of these healthcare centers in the country seems necessary.

In this descriptive-survey study, the statistical population consisted of 16 professional experts in hospital planning and design who were selected using the purposive sampling method. After reviewing 53 resources and conducting library studies related to the micro-hospitals in order to compare them with the existing healthcare centers in Iran, the related factors in establishment of micro-hospitals were selected and prioritized in an analytic hierarchy process (AHP) by statistical population.

The two factors of “easy access for users and the increased job efficiency of healthcare employees (due to the low number of patients)” were the ones with the highest importance.

Given the of data analysis, better access, the possibility of attracting patients on a local scale, as well as higher speed and job efficiency of employees, along with lower construction costs (due to the small scale of the complex), have been the highest priorities among the related factors. Thus, it seems that this idea can be a responsive solution to promote the healthcare service level in Iran.

Every year, many patients in different wards of the hospital die due to human error. One of the important aims in the field of human errors related to clinical care is to identify and prevent the occurrence of harmful effects caused by such errors. One of the preventive approaches in order to prevent human errors is to recognize and analyze them. The purpose of this study is to investigate all clinical care processes in the coronary care unit, identify human errors and prioritize the tasks and errors in this section.

Methods and Materials:

 This descriptive-analytical study was performed cross-sectional in three stages. In the first stage, human errors were identified and evaluated using the SHERPA approach and the frequency of each human error in the CCU was determined. In the second stage, the criteria and factors affecting the occurrence of human error in the CCU were determined by Delphi method. Finally, in the third stage, with the Analytic hierarchy process, the criteria and tasks that had the highest frequency of errors were prioritized. SPSS.24 and Expert choice.11 are two software that used to analyze data in this study.

Among the 116 identified errors with SHERPA, the highest percentages of errors identified from the total errors were related to the functional error (68.1%) and lowest percentages related to selective errors (2.58%) respectively. The results of different Delphi rounds showed that the factor of skill, experience, equipment, work time and workload are the most important factors which affecting the occurrence of human errors in the CCU. By pair comparison of this factors, we founded that experience and skill of nurses, with a weight of 0.278 and 0.272, have the most important and factor of equipment with a weight of 0.087, had the lowest important among the five effective factors for incidence of human error in the CCU. The task of extracting airway discharge with a weight of 0.125 was the most preferred among 16 tasks, in other words task of extracting airway discharge was the most risk of error in functional error. Factor of experience and skill as the most important factor in the occurrence of functional error. In the error type of recovery, the task of identifying drug information (time, date, dose and dosage form, etc.) with a weight of 0.054 was the highest rank in this type of error. The factor of experience and loading with weights of 0.018 and 0.01 were the most important, respectively in this type.

In the coronary care unit, functional and revisions errors in the vital tasks such as cardiopulmonary resuscitation, dose adjustment, and proper drug injection were the most common. Therefore, design and implementation of control measures such as periodic training on how to do the job properly, preparation of checklists with a focus on human behavior in different job processes recommended to eliminate or reduce the amount of identified errors in the hospitalchr('39')s CCU.

The purpose of this study is to identify and rank the factors affecting the quality of education based on brain-based learning. The approach of the present study was mixed (qualitative-quantitative). The statistical population in the qualitative section of experts has sufficient experience and expertise in the field of education and learning, which in this study is considered 10 people. The statistical population in the quantitative section of the professors of the Research Institute of Neurological Sciences affiliated to Baqiyatallah University and Allameh Tabatabai University, the statistical population was 50 people. Data collection tools are semi-structured in the qualitative part of the interview and in the quantitative part of the questionnaire. In the quantitative part of the research tool, a researcher-made questionnaire was made. Qualitative data analysis was analyzed by systematic data method and quantitative data analysis by Spss and expert choice software. The main and sub-categories related to brain-based learning statistics and causal factors affecting this phenomenon include: brain physiology factors, meaning search, perceptions, environmental factors, teacher role and physical activity, as well as two factors of educational organizations perspective and style support Brain-centered learning in educational quality was identified as underlying factors. Based on the results of the analyzes with AHP technique, the final weight of meaning search factor was obtained in the first rank, brain physiology factor in the second rank, environmental factors in the third rank, teacher role in the fourth rank, physical activity in the fifth rank and perceptions in the sixth rank.

Investing in health and safety has long been considered costly and inevitable, and the cost factor has always been a barrier to implementing safety and health interventions. Decision-makers in this area must demonstrate that such interventions are not only effective in achieving their goals but also have high economic efficiency. The present study aimed to determine the optimal model for economic evaluation in occupational safety and health investments.

The Analytic Hierarchy Process (AHP) method and Expert Choice® software were used to determine the optimal model. First, the OSH economic evaluation models/ tools were identified based on a review of previous studies. Then, considering 7 main criteria, the models were evaluated and the optimal model was introduced.

By literature search and screening of the findings, 20 models/tools were identified. then, using a decision matrix, modelschr(chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))39chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))) specifications were extracted and compared with each other. 4 models were identified for prioritization with AHP. The accuracy and precision with a final weight of 0.490 and the comprehensiveness with a final weight of 0.076 were the most and least important criteria, respectively. After prioritizing the alternatives over the target, the ROHSEI model, ToolKit method, Productivity Assessment tool, and Potential Method weighed 0.320, 0.281, 0.240, and 0.159, respectively.

HSE professionals can use ROHSEI as a tool for demonstrating the financial incentives for their goals, allocating limited resources, and improving the economic efficiency of their projects.

Evaluating portschr('39') environmental performance as one of the two main parts of the maritime transport system is of great importance. This study was designed and conducted to develop a method for evaluating portschr('39') environmental performance based on the fuzzy analytical hierarchical process.

The present study was conducted in 2020 with the participation of 22 experts in the field of environment and marine sciences. The study steps included a comprehensive review of the literature, design of an environmental performance evaluation questionnaire, development of a questionnaire in a Delphi study, and a method for evaluating environmental performance in ports based on a fuzzy hierarchical analysis process.

Based on the results of the fuzzy analytical hierarchical process, the final normalized weight for six factors of environmental performance, including reactive performance, active performance, sustainability, socio-cultural, economic, and governance, were estimated to be 0.202, 0.241, 0.226, 0.070, 0.080 and 0.182 respectively. Besides, it was found that each of the parameters in the factors affecting the environmental performance has a different weight and impact. The highest and lowest effects on the environmental performance index in this study belonged to the environmental risk assessment parameters with a weight of 0.217 (active performance factor) and cultural and justice effects with a weight of 0.107 (socio-cultural factor).

In this study, a novel method for evaluating portschr('39') environmental performance has been developed based on 6 factors and 32 parameters, and the fuzzy analytical hierarchy process approach. Therefore, using this method can be a practical step towards improving the level of environmental performance in ports to achieve the goal of "green port."

Construction is one of the most dangerous industries in the world and one of the authorities’ concerns of officials in this area is to improve their safety. This study was carried out so as to investigate the causes of unsafe behaviors in a combined cycle power plant.

In this cross-sectional study, a questionnaire for 300 workers of the combined cycle power plan were used. The obtained information was divided into criteria and sub-criteria affecting the causes of unsafe behaviors. Criteria and sub-criteria were distributed as a pairwise comparison questionnaire among 19 people who worked on the safety and they were supposed to answer based on their experiences as well as the distance scale. Criteria and sub-criteria were ordered by Analytic Hierarchy Process (AHP) and using Expert Choice software.

the results showed that the criterion of individual characteristics (34 %) is the most effective factor for unsafe behaviors and followed by employer (22%), teaching 915%), education (12%), specialization and experience (7.8%), age (7.6%), job characteristics (3%), and weather condition (2%) respectively.

the most important sub-criterion of individual characteristics is a onechr('39')s susceptibility to accident. Hence, it is necessary to prevent unsafe behaviors by employing vulnerable people in less dangerous occupations.

Waste production is a natural consequence of human life and mismanagement of solid waste can result in environmental hazards. Determination of an appropriate location to sanitary landfill site is one of the most common ways to deal with this crisis. The purpose of this research is to find an appropriate location for landfill site in Qorveh city due to its specific location in terms of agriculture and mining.

The research method in this study was descriptive, analytical and quantitative. In order to locate the landfill, firstly effective information layers in landfill site study (land use layer, rivers, roads, conservation areas, soils, groundwater, morphology, …) were identified and developed using the collected data from organizations and information centers. Finally,(GIS), (AHP) and (WLC) were used to integrate the maps.

The Analytical Hierarchy Process is one of the most efficient techniques designed for multi-criteria decision making, as it enables the formulation of complex problems. Due to limitations, appropriate landfill site options were identified using GIS and used as input data for the hierarchical analysis process. Distance from population centers (towns and villages), distance from surface and groundwater sources are the most important indicators.

By combining two methods of multivariate Weighted Linear Combination (WLC) and Analytical Hierarchy Process(AHP) model, the most priority areas were determined with concentration on distance from population centers (towns and villages), distance from surface and groundwater resources,. After extracting the criteria information layers from the maps and prioritizing the 4-storey location ranges, it became clear that the northern direction of Qorveh city with an area of ​​210 hectares is the most suitable area for sanitary landfill of solid wastes.

management of change is one of the requirements of quality standards  in dynamic industries. Make changes without evaluation can be a challenge, if not managed properly, can be irreparable damage. Failure to management of change can cause an organization in the HSE area to face many problems, including accidents and work-related illnesses or unwanted environmental pollution. Determining the criteria for assessing the consequences of change may help the organization determine whether this change is in the organization or not. On the other hand, change in the organization is compulsory in many cases. Assessing and determining the causes of the impact of a change can help the organization to improve its readiness to deal with possible emergencies through the implementation of a change. Any change in the manpower, equipment, processes and procedures of the organization will be likely to create new health, safety and environmental hazards. The management of change process helps to ensure that the organization (production or service) operations are carried out safely and reliably. It should be noted that many policies, safety instructions and safety processes have been created in the organization based on traditional thinking and are less reviewed and changed, which does not interfere with the changes that have occurred in the technology. The aim study aims to provide a change management model with the HSE approach.

In this study, firstly, the contributing of change management process were defined based on the HSE approach according to available resources. In the first stage, 15 criteria and 40 sub-criteria were determined. Then, using the expertschr('39') opinion, the most important ones were selected, in which 5 criteria and 12 sub-criteria were defined. In this research, expert someone who has at least a Bachelorchr('39')s degree in the field of HSE, industrial engineering or industrial management. Also have at least 10 years experience in the copper industry. At this point, 10 experts were selected. A pairwise questionnaire (prepared by researchers) was used to collect expert opinion. Experts were used to determine the validity of the questionnaire. Matrix correlation coefficient as well as Cronbachchr('39')s alpha coefficient were used to change its reliability. At this stage, we used the FAHP method to determine the weight of effectiveness and prioritization of the criteria. To provide a conceptual model of the study, it was necessary to determine the relationship between the criteria to determine which criteria were defined as being setting Effect measures in the change management process and which criteria were defined as a receiver Effect measure of the management of change process. In this section, research and determination of the criteria of the criteria was used with the main change management process from DEMATEL. DEMATELchr('39')s results were categorized into two setting Effect and receiver Effect groups. Based on the results, it was proposed to present a decision model for assessing and ranking the changes, as well as providing a decision model for assessing the implementation of the change. At last, Based on the results, a linear model was proposed for evaluating and ranking the changes, as well as providing a decision model for evaluating the implementation of the change.

In the first stage, the results of FAH in determining the weight and ranking of main criteria showed that among the main criteria, the main criterion is the consequences of the change and then the ability to execute the change. The lowest priority is the change type, which has a lower rating. In the case of sub-criteria, the results showed that among the sub-criterion that influences the management of chang process, the following is the highest priority under the criterion of the level of effectiveness and type and outcome probability, and the budget and facilities needed. Changes in equipment and organization and manpower are of the lowest priority.The results of the DEMATEL section to determine the internal relations of the criteria with the change management process for the conceptual modeling of the research showed that the highest criterion of setting Effect among the sub criteria is the type of change with the sub-criterion of organizational changes and the ability to execute with the sub-criterion of the required facilities and HSE management With a safety degree. Also, the most receiver Effect measure in managing change is the change outcome with the sub-criterion of the type of outcome and the standard of HSE management with the sub criteria of environmental pollution.According to the results obtained from normalizing the data, the decision model of priority and choosing the changes defined is as follows.Where in; S is degree of Safety, H is degree of Health, B is Budget required, F is facility required, O is organization, Hu is Human, Ma is Management, Eq is equipment. It should be noted that all defined parameters have 0 or 1 state (they are realized 1 and they are not reached 0). It is clear that as much as the number of ASSESS is higher, the defined change has a higher priority in execution.According to the results obtained from the normalization of data, the decision model is the priority of implementing the defined changes as follows. Where in; I is conseqence of change (if consequence is acceptable I is 1. If consequence is unacceptable I is 0), Ip is probablity of conseqence (if probeblity is high then Ip is 1. If probability is low, then Ip is 0) , P is performance (if performance is acceptable P is 1. If performance is un acceptable P is 0), E is environmental pollution (if changes cause enviromental pollution, E is 1. If changes don’t cause environmental pollution, E is 0). It should be noted that all defined parameters have 0 or 1 state (they are realized 1 and they are not reached 0).

Using change management models can make changes without putting a lot of challenge. In the copper industry, due to changes in environmental conditions and the dangers of this industry, the cosequence of change is prioritized. In other industries with their own structures, creating a change management structure may vary. The results show that the most important issue in the change management process is the assessment of executive capacity and the assessment of the consequences of the change. Also, in evaluating the feasibility of making changes, there is a need for comprehensive studies to be made so that we can properly and accurately plan the resources needed to implement the change. Using decision models, especially the use of models that represent the internal relations between decision-making criteria, can act in the formation of new conceptual models with a new approach.

Fall from height is one of the main causes of death in the construction workers. Therefore, this study aimed to identify and prioritize the factors affecting falls from height accidents in construction industry.

A descriptive-analytical study was conducted on five constructional projects in Pars Jonoobi industrial region, Iran. All of the reported events from 2011 to 2015 were investigated and 74 out of 377 occupational accidents were considered as falls from height accidents. The identified factors and sub-factors were divided into 3 main factors including individual, organizational and environmental factors and 14 sub-factors based on the experts’ opinion. Then, AHP method was used to determine and prioritize of the factors and sub-factors.

The results of hierarchical analysis of fall from height accidents causes showed that environmental, individual, and organizational factors with weights of 0.359, 0.351, and 0.290 were in the first, second, third priorities, respectively. Meanwhile, among all examined sub-factors, work platform elevation, mental/ occupational stresses and safety culture had the highest priority.

Paying attention to the strategies that enhance the safety culture of employees and reduce their occupational stress levels in the workplace can be very effective in preventing of fall from height accidents.
