Recognizing the threats of the sales center and eliminating them can have great effects on improving the performance of the organization.  The purpose of this research is to identify and rank the pathology of Faraja's sales center. Based on this, the current research is an applied-descriptive research.

The statistical population of this research includes all managers of logistics and support sales center. The target statistical population, 52 people, was studied based on Morgan's table. Data collection in this research was done in two ways to reach the pathology of the sales center. In the first method, interviews with officials and technical experts were used, and in the second method, a researcher-made questionnaire was used. This research was conducted to answer seven questions, and T-Tak-test was used to analyze the results.

The results of the T-Tak test show that, regarding the analysis of damage to the sales center, the items "supervising the collection and maintenance of unused service items in the ranks" in the mission damage, "adequate compensation for the sales center employees" in the structural damage, "considering the interests of the parties" (Faraja and customer)" in financial/credit damage, "holding an auction according to the existing financial and accounting laws and regulations of the country" in legal damage, "updating and upgrading the functional capabilities of computers in the sales unit of the administrative provinces" in technology damage, "to "minimizing administrative bureaucracy" in process damage and "presence of inspection and protection representatives during auctions and especially visit days" in security damage are more important than other items.

The results showed that there are currently no damages in the sales center in terms of mission, structural, financial/credit, legal, technological, process and security damages.  It should be noted that if the sales center does not pay attention to the results of this research, it has the potential to be damaged in the long term in terms of technology and financial/credit.

The present research was conducted with the aim of identifying the requirements of institutionalizing the culture of maintenance and repair in the armed forces of the Islamic Republic of Iran.

The current research is applicable in terms of purpose and is descriptive in terms of method. This research includes two research methods, the first part is the review of research literature and the second part is Delphi. The statistical population of the research includes all maintenance and repair experts of the Police of the Islamic Republic of Iran (Faraja). To maintain the credibility of the research and considering the drop of respondents during the study and after refining and applying the desired indicators, a list of 21 people was announced. According to the data obtained from Delphi rounds and different sections of the questionnaire in each round, statistical indices, minimum and maximum, average, mean and standard deviation were calculated. The distribution of the questionnaire was done in three stages according to the Delphi method, and in each stage, the items that had an average of more than four were included in the next round, and components with an average of less than four were removed and not included in the next rounds of the questionnaire. For the consensus of the experts, it uses the method of reaching a certain level of agreement and also the Kendall correlation coefficient criterion to make a decision about stopping the Delphi steps.

The results showed seven components of safety culture, organizational structure, employees, values, behavioral factors, organizational factors, continuous improvement, diligence, and work commitment based on experts' opinions as requirements for institutionalizing maintenance culture in the armed forces of the Islamic Republic of Iran.

In order to institutionalize the maintenance culture, the commanders of the police Forces should consider the listed components.

One of the effective methods of logistics is to have a proper maintenance and repair system With the purpose of reducing insecurity and improving the readiness of the equipment. Meanwhile, speed and quality have a significant impact on the cycle of requests and receiving segments from the subgroup to the origin and recognizing possible pathology will give the managers of the organization to solve the current problems and function better. With this perspective, the current research is conducted with the purpose of pathology of the mentioned cycle in a military organization.

This research is applied in terms of purpose, and descriptive-survey in terms of type. The statistical population of this research is the entire logistics and support employees of the studied organization, and by distributing 30 questionnaires among the statistical population and determining the variance of the initial sample, the sample size was 110 people. The main tool for collecting information in the research literature section was library studies, and a questionnaire with field distribution was used to collect data. The validity and reliability of the research was confirmed by Cronbach's alpha method. Confirmatory factor analysis and t-test using SmartPLS3 and SPSS23 software analyzed the obtained data.

The main finding of this research showed that the status of the cycle of requesting and receiving segments in this organization is not appropriate. In addition, because the difference between the obtained average and the test value was not significant, therefore, the condition of the cycle of requesting and receiving segments from the maintenance and repairing unit sub-set to the source of supply in the studied organization was evaluated as average..

In order to correctly and timely request and receive the required segments in the maintenance and repairing department, indicators such as the suitability of the working environment conditions, the appropriate composition of the workforce, laws and regulations, as well as the development of comprehensive instructions and obstacles for the process of receiving the required segments of the department Disorders are needed.

The purpose  this research is  survey the barriers and problems of using road-rail multimodal transportation in moving cargo and military cargo of a militia and to provide solutions to reduce these barriers and problems.

This current research is from mixed/combined kind using questionnaires. The statistical population of the research includes the senior managers of logistics, support, transportation, and mobility experts of the organization. In this research, firstly, through library studies and interviews with logistics and support experts and university professors, primary criteria and sub-criteria of barriers and problems of using road-rail multimodal transportation were extracted, and research questionnaires were compiled. Then these questionnaires were distributed among research experts. To determine the validity of the questionnaire, Lawshe formula was used, and to check the reliability the questionnaire, Cronbach's alpha coefficient was used. To determine the importance of these criteria and sub-criteria, the best-worst (BWM) method, which is a new approach in multi-criteria decision-making theory, was used.

In order to fulfill the purpose of the research, 41 sub-criteria were identified and categorized in four main criteria including "infrastructural barriers, safety and security actions barriers, managerial and technical barriers and financial barriers". In the first field research, validity and reliability of research criteria and sub-criteria were proved, and the best (most important) and worst (least important) criteria and sub-criteria in the barriers and problems using road-rail multimodal transportation in movement of cargo and military cargoes were calculated. In addition, in the second field research, the importance of these criteria and sub-criteria was determined by the best-worst decision-making method (BWM).

The results of research showed that main criterion "infrastructural obstacles" has the greatest effect on the use of road-rail multimodal transportation for moving cargo and military cargo. Also, the main criteria "management and technical obstacles, safety and security actions barriers and financial obstacles" are the next priorities.

In this article, different approaches of traditional risk analysis and the phase-based multi-criteria decision-making application for quality analysis of CNC milling machine are examined. The proposed framework of this article can help the system analyst and maintenance engineer with better planning by identifying and prioritizing risks.

The statistical population of this research is 25 people and consists of experts in the fields of design, production, maintenance repair, safety and quality control. In this method, five working committees with different specializations have been used. Specialists are graded according to specific characteristics including education level, age, job position and work experience. The weight of each group of working committees is determined based on the composition of the experts. First, by using the cause and effect diagram and brainstorming method, failures were identified. A questionnaire was distributed for each of the breakdowns identified from the cause and effect diagram (Fish Bone), and opinions were collected with language expressions on a 7-point Likert scale, and the breakdown situations were prioritized using the TOPSIS phase method. Also, different traditional and phase FMEA approaches were compared.

A total of 17 failure modes were identified, seven of which were evaluated as critical for the system. In the current study, the defects of the spindle connections, the failure of the axle and bed brakes, the failure of the Y-axis bearing, the failure of the control panel handrail, the failure of the C-axis, and the failure of the Hayden Hein control panel control system. The device is identified as a priority failure and the failure of the HMI control panel as a critical failure mode.

Since about 41% of the malfunctions identified in the device under study are critical, it is necessary to plan and implement preventive maintenance and repairs for them.

In the procurement process, small and medium-sized enterprises (SMEs) are often in a weak position when facing strong suppliers. Adopting a joint procurement strategy that represents the long-term horizontal cooperation of SMEs in a procurement process, can be considered as an attractive and efficient strategy. Therefore, the purpose of this paper is to propose a mathematical model and optimization algorithm for the decisions related to sourcing and inventory management of SME’s procurement alliance.

In the proposed joint procurement model, SMEs are able to obtain quantity discounts and reduce the total purchase cost by aggregating purchase demands to a relatively larger-scale purchase order. Therefore, the model determines order quantity of each SMEs in the procurement alliance from each of the suppliers in order to minimize the cost of procurement, the number of defective purchased materials and the number of delayed materials delivered. In addition, in this model, the constraints of minimum order quantity, inventory capacity and purchase demand are considered. To examine the validity of the model, a real example using the non-dominant sorting genetic algorithm II (NSGA II) has been optimized.

The results of the numerical experiments showed that the joint procurement model and the proposed optimization algorithm are effective and three objectives are significantly improved in the joint procurement scenario comparing with the independent procurement scenario.

In this article, a multi-objective model for supplier selection and order allocation in the joint procurement process of SMEs is presented. In addition, constrained non-dominant sorting genetic algorithm has been developed to optimize this constrained multi-objective model.

Todays, new technologies are a potential factor to improve the performance of the supply chain. The use of these technologies can help companies improve their performance in the supply chain as a competitive advantage. One of these emerging technologies is the Internet of Things. The purpose of this research is to determine the impact of Internet of Things on chain management.

This research is applied from the point of view of the objective and descriptive survey from the point of view of data collection. A questionnaire was used to collect data. The statistical population of the research consists of 220 people from the managers of the first company, of which 160 people participated in the research as a sample. In order to analyze the data through confirmatory factor analysis using Amos, SPASS software was used.

The obtained results indicate the impact of Internet of Things on supply chain management. Also, this effect on all four main dimensions of the supply chain includes; distribution network, distribution strategy, information flow and inventory management.

The Internet of Things has an impact on the organization of the distribution network and increases the speed of information circulation, which makes it possible to manage the inventory effectively, and accordingly, the distribution strategies can be adjusted and implemented accordingly.

more than 50% of the current costs of an organization are related to purchasing, which includes a large volume of the company's turnover, and by optimizing it, it can provide services with a lower cost and improve the level of competitiveness of the company's product/service. The purpose of this research is to present the optimal purchase model in the sugarcane development company and related industries, as well as to identify the antecedents and consequences of optimal purchase.

This research is among qualitative and quantitative research. In the qualitative part, a semi-structured interview was conducted with experts in the Sugarcane Development Company for data collection, and after conducting 12 interviews, the data were analyzed using a combination of thematic analysis and theoretical coding using Atlas T software. In the quantitative phase, the authors tested the model using structural equation method with the help of PLS software.

In the qualitative part, in order to collect data, the opinions of experts in sugarcane development company and ancillary industries were used. The selection of people in the qualitative section was based on the purposeful and snowball sampling method. In order to ensure the theoretical adequacy of the data, the researcher (12) has conducted an interview.

The results of the qualitative phase of the research showed that the most important antecedents of the optimal purchase model include quality improvement, coding system, order management, budget, human resources management, and competitiveness, management of information and communication technologies, and elimination of unnecessary administrative bureaucracy. In the qualitative section, it was also found that the most important consequences of purchasing optimization include improving performance, productivity, efficiency in production and improving the organizational brand. The results of the quantitative phase of the research also indicate the appropriate fit of the presented model.
