Cultural ecosystem services, as one of the components of ecosystem services, are intangible human benefits from ecosystems that play a fundamental role in promoting human well-being. Rapid changes in land use with damage to ecological assets in the Ilam urban watershed have reduced the capacity of ecosystem services, including aesthetic quality. Therefore, the evaluation of the supply of aesthetic ecosystem service, which shows the biological diversity in urban areas and favorable conditions for life, is considered essential for inclusion in the improvement plans of Ilam city in line with appropriate management measures. In this vein, in the current research, an integrated approach to prepare an aesthetic map with the aim of showing the spatial distribution of the supply of aesthetic services in the Ilam urban watershed has been presented, the results of which can greatly influence planning and managerial decisions regarding future development towards urban sustainability by preserving natural ecosystems.

Spatial distribution of providing aesthetic ecosystem services in Ilam urban watershed using 12 visual and ecological criteria including: slope, Elevation, geomorphology, land use, habitat characteristics, visibility of various areas, visibility of roads, visibility of residential areas, visibility of the river, visibility of the park, type and density of vegetation were investigated. To prepare visibility layers, Viewshed function was used in TerrSet Idrisi software. Then, the input layers were integrated using fuzzy membership functions and using the weighted linear combination method in the ArcGIS 10.8 system. Among the multi-criteria decision-making methods, Analytic Hierarchy Process (AHP) method was used to prioritize the criteria.

Based on the results of the hierarchical analysis process and according to the results of the experts Among the input criteria, visibility of the river, type of vegetation and visibility of diverse areas were assigned the most weight with values of 0.14, 0.127 and 0.116 respectively. On the other hand, the least importance and weight was observed in the measure of road visibility. Based on the final map of aesthetic quality, the best quality of this service is in the parts of the north, east, southeast and west of the Ilam urban watershed, where these places have the best visibility of the river, visibility of various areas, high to medium altitude and with dominant forest cover.

The results of this study showed, that areas with forest cover and areas with human uses have the highest and lowest capacity of this service in the study area, respectively, which denotes the importance of natural green uses compared to artificial uses and human-made is in providing aesthetic service. These results indicate that the capacity of the watershed ecosystem of Ilam city in providing aesthetic services varies in different places and is influenced by various factors, especially topographic changes and land use patterns. That is to say, prevent land use change is an important factor for maintaining ecosystem services. Because the land use Changes pattern affects the capacity of the ecosystem to produce goods and services. The results of this research also, by presenting the spatial distribution model of aesthetic service potential can be useful for decision makers, managers and urban planners in order to monitor and protect aesthetic values and it is important and useful to adopt urban landscape management strategies and plans in the landscape of the studied area.

Sustainable supply chain management is a new approach in the discussion of supply chain management, which is considered based on the concepts of sustainability triangle (Economic, Environmental, Social). In the meantime, choosing a sustainable supplier is a strategic key to success in managing the sustainable supply chain of organizations. Choosing the best supplier according to different and sometimes conflicting criteria complicates the problem that using multi-criteria decision making methods is one of the best ways to solve these problems. On the other hand, the choice of supplier is strongly dependent on the opinion of decision makers, and due to the incompleteness of available information, we face a kind of uncertainty.

 In this paper, the issue of choosing a sustainable supplier in Cement Company is examined. To do this, the combined SWARA and CoCoSo fuzzy approach was used to weight the criteria and rank the suppliers. In the first stage, after collecting the criteria for selecting a sustainable supplier based on the research literature, the criteria were weighted using experts and the F-SWARA method.

The weighting results showed that the economic dimension (0.555) had the highest importance and the environmental (0.296) and social dimensions (0.146) were in the second and third places. Among the criteria, product price (0.284), environmental standards (0.154) and product quality (0.140) gained the highest weight, respectively. Supplier ratings were then calculated using the new F-CoCoSo method, and supplier ratings were obtained for final decision.

According to the criteria of a sustainable supply chain in this study, managers and owners of various industries and businesses according to the findings of this study can choose the right supplier who lives from all three economic dimensions. Environmentally and socially appropriate, take steps and enjoy its benefits.

Locating to develop infrastructures and sensitive applications is one of the preconditions for achieving sustainable development. In this study, using a multi-criteria decision making model and the capabilities of the GIS, a spatial model is developed for the development of various industrial groups in the province of Alborz.

In this study, the criteria and indicators affecting the development of industries identified by reviewing the references and expert opinions. Then, using the fuzzy hierarchical analysis, the weight of each of the criteria and indicators was determined using the weight the obtained data are based on a linear relationship between the map of areas susceptible to industrial development in the region. In order to the fuzzy hierarchy TOPSIS method used to identify the areas for the development of each the industrial groups.

The results of this study show that among the three groups of environmental, economic and social criteria, environmental criteria have the highest weight in relation to industrial development. Also, the results showed that the highest potential in relation to the development of industrial groups in the Alborz province is related to food and agriculture industries.

Based on the results of the study, using efficient fuzzy decision-making models to address the defects of other decision-making methods. Analysis of the results shows that in many parts of the province of Alborz, there is no development of industries. The most limitation for development of industries in Alborz province is related to environmental criteria and indicators.

To determine and zonation of flood prone hazardous area and prioritization the sub-basins in terms of flood potential can have great contributions in promising watershed management. The present research aims to prioritize flood and sedimentation potential in the sub-basins of the Bonekooh watershed using TOPSIS, SAW, ELECTRE and VIKOR methods.

In this present study, we used area estimation indices, drainage density, gravel coefficient, basin average height, basin average slope, curve number, sediment yield, cover percentage, sediment delivery ratio, runoff height and concentration time as an important indicators affecting water permeability, runoff production and, consequently, the potential for flooding and sedimentation. Then, using the Analytic Hierarchy Process (AHP) method, the weight of each index is met. Following the formation of decision matrix with 18 options (sub-basins) and 11 criteria (evaluation index), Technique for order Preference by Similarity to ideal Solution (TOPSIS), Simple Additive Weighting (SAW), Elimination Et Choice Translation Reality (ELECTRE) and Vise Kriterijumska Optimizacija Kompromisno Resenje (VIKOR) techniques were used to prioritize sub-basins. Borda and Copland methods were used to combine the rank of proposed techniques. The residual sum of squares (RSS) method was used to determine the closest method to the final result. Also, in order to validate the models, we estimated the percentage change and the intensity of the changes.

The results showed that the highest runoff height index (0.18) and the gravel coefficient had the lowest weight (0.028), according to experts. Prioritization results showed that in SAW, TOPSIS and VIKOR methods, sub-zones 9, 4, and 2 ranked first to third priorities respectively and are in a more critical situation, but in the ELECTRE approach sub-basins 9, 4, 2 and 7, respectively, have the first to third priorities. Considering the results of the combined ranking of the proposed techniques, sub-basins 9, 4 and 2 are in first to third priority, respectively, and have a more critical situation than the rest of the sub-basins. Also, zones with flood and sedimentation potential in the area showed that 32% of the area in high and very high risk. The results of the sum squared error showed that the VIKOR method had the least error and the ELECTRE method had the most error than the final ranking. Also, the TOPSIS and VIKOR methods with the lowest percentage of change (59.72%) were ranked first and the ELECTRE method with the highest percentage change (65.27%) is the last rank. The lowest intensity was also observed in the VIKOR method (4.59) and the highest intensity variation was observed in ELECTRE method (5.61).

Therefore, it can be said that multi-criteria decision-making techniques are a practical and appropriate approach for better decision-making based on mathematical sciences and optimization. Therefore, these types of low-cost and fast-track research can be prioritized to protect watersheds.

Marine Structures projects, especially the construction of oil platforms, are faced with numerous risks in different stages of design, construction and exploitation, due to factors such as the extent of resources and Uncertainties. Identification and assessment of these risks as one of the most important measures in the risk management process, will have a significant role in better planning of these projects by managers.

In this study, in order to manage the risk of oil platforms project, first, all possible risks in the fields of engineering, executive, environment and passive defense were identified in a library form, and among them,  according to experts’ opinions, 26 risks Were identified as important and effective risks on the project. Finally, to assess and prioritize the risks, multi-criteria decision-making models were used in the fuzzy mathematics environment.

In this regard, after setting the questionnaire to test the hypotheses of the research, relying on experts’ opinions, identified risks were ranked by TOPSIS model in fuzzy environment.

Survey of the resulting rankings shows that the option of incorrect design due to defect in geotechnical studies in the field of engineering,  the option of stopping executive operations due to lack of supply of providing necessary materials and equipment due to the sanctions in the Executive field, the option of arson and explosion in the field of passive defense and the option of sea water pollution in the field of environment as the most important risks affecting in each of the four areas of the project are studied.

Qaen City is the administrative and political center of Qaenat County in south Khorasan province. Since the use of land is without consideration of ecological potential in addition to environmental degradation, it will also be diverted from sustainable development. Therefore, it is necessary to determine the ecological capabilities of the city for its urban development. This research was conducted with the aim of determining suitable locations for urban development in the Qaen City, South Khorasan Province. For this purpose, using multi-criteria decision making methods (MCDM), the weighted linear combination method was chosen due to the possibility of standardization and assigning different weights to the criteria and in geographic information system based on observations of the natural environment (6 criteria), city ecological potential was evaluated within the limits of the city's final privacy. The results indicate that From a total of 225.12 square kilometers, the area of study area, 50.21 square kilometers is suitable for urban development And 7.26 square kilometers of moderate proportion and 1.95 square kilometers have a small proportion of urban development And an area of 165/7 square kilometers was considered inappropriate for the development of the Qaen City, and has no urban development capability.

In recent years, rangeland degradation has reduced a wide range of ecosystem services for billions of people whose livelihoods depend on natural resources. Proper rangeland management can multiply the rangeland's capacity to benefit from ecosystem services. The dominant model of rangeland management is the preparation and implementation of pastoral plans. These plans, if not be properly selected and not be based on rangeland ecosystem services improving, in addition to exacerbate the downward trend of rangelands, also will result in the loss of capital. Therefore, by recognizing the effects of different management methods on ecosystem services, it is possible to change or modify rangeland management patterns. In the present study, we ranked rangeland management plans methods in Fars province using multi-criteria analysis in the context of rangeland ecosystem services.

One of the major causes that hinder consideration of the value of ecosystem services in computation and evaluation are the heterogeneity of the different types of value measurement units, the impossibility of quantifying all values and the problems associated with the integration of quantitative and qualitative data. Therefore, given the capabilities of multi-criteria analysis methods in analyzing heterogeneous data, these methods are suitable tools for overcoming this problem and for making more reasoned and informed decisions. In the present study, fuzzy hierarchical analysis (AHP) was used to determine the weight of criteria and indices. Then, using the results of the first step as input of the PROMETHEE software, the rangeland remediation options were ranked using the PROMETHEE II analysis.

According to the literature on the subject and discussion with rangeland and environmental experts, 12 indicators were defined for four categories of ecosystem services. After determining the criteria, weight of criteria and indices were calculated using hierarchical analysis method. Paired comparisons of ecosystem services criteria indicated that regulatory and support services with a weight of 0.734 are more important than production and cultural services. The results of paired comparisons of ecosystem cultural service indices showed that biodiversity criterion was much more important than landscape, recreation and ecotourism criteria. Paired comparisons of sub-criteria of ecosystem services indexes showed that grazing capacity and profitability of livestock products with the relative weight of 0.555 and 0.224 were the highest importance among ecosystem services indices, respectively. In addition, rangeland water resource capability index with significant weight of 0.475 is in the first place of impact on ecosystem regulation and support indexes and soil erosion prevention index with the weight of 0.352 is ranked second. The final weight of each index was obtained by multiplying the relative weight of the criteria by the relative weight of the indices. Among the ecosystem services indexes, water resources weight was 0.35 which was the highest weight. After water resources, the role of the ecosystem in preventing soil erosion is the most important indicator evaluated. The third most weighted indicator is biodiversity. After data entry into PROMETHEE software, the results showed that among the various pasture management options, enclosure was ranked first. Therefore, the enclosure plan provides the most ecosystem services. 11 indicators had a positive effect on enclosure priority and the only indicator that had a negative effect on enclosure priority was access to water resources. To validate the results, sensitivity analysis was performed in three different scenarios. Results of sensitivity analysis showed that due to water shortage crisis and high importance of this index in rangeland ecosystem services, priority of rangeland options is not sensitive to changes in other indices.

According to the results, the exclosure plan provides the highest ecosystem services in rangeland management and the least ecosystem services in medicinal plants. After exclosure, priority is with water projects includes springs refurbishment and pond construction. In order to better management of rangelands in Fars province and the necessity of ecosystem services consideration in rangeland plans, we can obtain valid evaluations by applying multi criteria methods.

Physical development of cities around the world is influenced by its natural geography and human interactions. Geographic data analysis is difficult without the use of geographic information and satellite data, and impossible in a complex case. In this study, potentials and barriers of physical development of the Ruodbar city using Remote Sensing and GIS be evaluated.

Firstly, in the ArcGIS software environment, using the AHP-FUZZY combination method the use of slope, gradient, land use, power lines, river, road and rail, fault and rural points are used to locate the urban sprawl. The output was extracted in the form of a map of AHP and fuzzy overlay into five groups with very good, good, moderate, weak and very weak potential. In order to expand the city's physical development by using a visual interpretation on Google Earth images for 2016, 2009, 2004 for 12 years, a map was drawn out as the result. Finally, the results obtained from the Geographic Information and Visual Interpretation System were compared.

The findings of the AHP-FUZZY compilation show that 95.6% of the study area has very weak potential, 1. 52% has a weak potential, 1.17% has a moderate potential, 1.21% has good potential and 0.69% has a very good potential. And the findings from the visual interpretation method over the course of 12 years show that the development of the city is just Mehr Housing (a project done government).

Based on the findings of the AHP-FUZZY Compilation and Metrology Measurement, we concluded that most of the constructions have been implemented in unpredictable places in the city of Roodbar, which is influenced by natural and inevitable factors, including steep slope, abundant faults, permanent existence of Sefidrood river, and land use, most of which are gardens and forests and agricultural land and has prevented its physical development.

In fact, ecotourism is a responsible tourism to natural environments that preserves environment and stabilizes local community. Since nowadays, man does not take a responsible approach towards nature and environment, the assessment of ecological potential as a strategy for rational use of land is necessary.

In this study, considering the region ecological potential for tourism, implementation of planning model for this usage and zoning the regions which have potential for tourism is carried out. From the viewpoint of the goal, this research is functional and considering study style, it is descriptive and analytic (cross –sectional). As a result, to give weight to the criteria, ANP-DEMATEL interactive multi criteria decision making model was used and to standardize the criteria, fuzzy logic was used. Then by applying weighted linear combination (WLO) layers were combined together and a distribution map were extracted for the areas that have potential for tourism.

The results showed 73.1 % of the region is suitable for ecotourism development and only 11.4 % of the region doesn't have the potential which is located in sloping areas.

 Finally, we can conclude that ANP-DEMATEL integration of hybrid models with fuzzy logic ensures superior performance on the location of recreational areas and effective solution to help provide assessment team to decide this.

In today's global business, competition is very intense between organizations and to impress clients, organizations need to put themselves in a better position than competitors. Environmentally friendly and compatible with environmental requirements are the way to distinguish from other competitors. If the competitors have benefited from the green supply chain management, the company will be under greater pressure to establish a green supply chain management. Customers also have an important role to deploy. Thus, strategic management, green supply chain is requirement for success in today's competitive market and should be considered seriously.  The aim of this study was to identify and rank the green supply chain management strategies using ANP method. Numbers of criteria identified in this study are 14 criteria in four categories: green design, green shopping, green manufacturing and marketing. The results showed that among the four risk-based strategies, efficiency-oriented, innovation-driven closed loop, efficiency-oriented strategy is the optimal strategy. In addition, the standard of green design has the highest priority.

In contrast with the main parts of district, there are some regions in the western, southwestern and northern parts of mentioned district where are almost safer and more secure.

Because of various faults and urban blight areas, the district 20 of Tehran is treated seriously by earthquakes. It is really vital to take some actions to implement some essential and fundamental proceedings in order to reduce the probable damages.

Urban parks have a significant role in reducing air pollution and improving the quality of life of the people living in urban areas. Planning and site selection of urban parks can significantly change a man-made environment to an ideal human society and enhance the quality of life and identity of the inhabitants by promoting the visual beauty and reducing the adverse effects of industrial development. The aim of this study was to evaluate and locate neighborhood parks using the principles of multi-criteria decision making (MCDM) in Ardabil city.

The used method was functional in terms of its objective and descriptive analysis in terms of its nature. The studied criteria consisted 12 components grouped for the spatial distribution of neighborhood parks. In this study, CRITIC techniques and pair-wise comparison were used to weight the criteria. Subsequently, the Vikor multi-criteria decision-making method was used in IDRISI to develope an appropriate model for the spatial distribution of green spaces in Ardabil. The obtained results were presented in the form of a graded map of desirability of place.

The results show that priority pixels introduced in the model output have optimum conditions in terms of the defined criteria. Discussion and

This model can be used as a decision support system in the spatial distribution of the existing neighborhood parks.

Introduction &Aim: Environmental pollutions are the side effects of industrial activities which put the environment in danger. On the other hand, by growing the population and increasing the electricity usage in the country, it’s necessary to construct new power plants. Power plants were prioritized based on different criteria. In this research based on the environmental, social and economical dimention , Kahak wind powerplant (the biggest wind powerplant) and Pakdasht Combined cycle powerplant (the biggest combined cycle powerplant in Iran) were studied.

In this research, Multi criteria decision making methods such as AHP and Topsis were used .to select the priority of the power plants. These two are the most important and optimal decision making methods .

Finally, based on the strategic environmental planning (EMP) table an action plan was presented

The comprehensive identification of hazard risks in order to protect against them is one of the main steps in environmental management. Given the importance of environmental impact assessment in sustainable development, the development of a comprehensive system consisting of effective indicators is vital for the creation or exacerbation of environmental risks, on the one hand, and their monitoring, on the other. This comprehensive system can provide categorized information for different levels of decision-making and management. This study aims to assess the vulnerability to zoning of environmental risks by applying an ecosystem services approach. It also aims to integrate the ecosystem services concept into environmental risk assessment.
Initially, a complete list of environmental risks was prepared by desk study, using provincial and national documents and field studies, along with meetings with different institutions. This list consists of all potential or active factors that can lead to risks. The prepared list of risks was reviewed by experts in order to have their feedbacks and to finalize it. In this study, different risks, including an imbalance in provincial development, the likelihood of water erosion and fire, land use change, and incomplete protection of biodiversity were analyzed. AHP multi criteria decision making was applied for zoning the imbalance of industry with ecological suitability. RUSLE was applied for soil erosion and MAXENT for fire and incomplete protection of wildlife. To study land use/cover changes, cellular automata and the genetic algorithm were integrated.
The results of setting priorities using the multi criteria decision making technique revealed that some risks, including imbalance of industry on land, erosion, vegetation and land use changes, fire and incomplete protection of wildlife are the major risks to be considered. Results show that quality of the ecological area of Alborz Province has significantly reduced in recent years due to human factors such as the establishment of factories, creation of various industrial zones, soil erosion and degradation, drought, depletion of water tables, loss of accessible water resources, improper cropping patterns, population growth due to immigration from other provinces and climate change. The results of vulnerability assessment show that a massive pressure was exerted on sustainable use of the environment of Alborz Province by human impacts. Alborz Province suffers from various risks for which applying environmental services, such as conservation of soil nutrients, biodiversity and diverse vegetation of land, can be effective in their reduction.
Environmental risks are major threats to the degradation of resources and environmental services in Alborz Province which should be controlled and prevented. Complete identification of pre-existing risks and their spatial analysis can help in the development of conservation strategies for vulnerable areas.

Urban parks are crucially important in improving quality of life in urban communities. Since, health and safety of citizens depend on health and safety of the environment, application of HSE-MS to identify the hazards and control them in urban parks seems necessary. The objectives of current study were to rank the factors influencing HSE management of urban parks and to present a model for HSE evaluation of parks.
In this study, HSE factors of urban parks were ranked by using F.TOPSIS. Then a model was established based on scalograph method to determine desirability of HSE-MS in urban parks. The model was examined in three urban parks at Karaj.
The results from validation of the proposed model in three urban parks indicated that, health and safety of environment in Iran Zamin and Tandorosti parks were moderate while they were weak in Ebne Sina Park.
The proposed model for evaluation of health and safety of environment in urban parks was precise; however, application of other MCDM approaches was suggested to reach a more comprehensive model.

In real world situations, available data to decision makers are often uncertain and imprecise due to measurement errors and incomplete understanding of the situation by the decision makers, normally, But also wrongly spatial multi-criteria decision making is conducted without due regard to data errors and their propagation in the process. However, these errors can propagate during the decision making process and get confounded by other errors including criteria relationships and ultimately impact on the final decision made. In this research, error analysis was carried out regarding spatial multi-criteria decision making that included uncertainties in factors and their associated weights. Urban suitability mapping for Tehran Province provided a case study in which two methods were used to introduce errors and assess their effects: 1. insertion of errors in each factor and simulation of their propagation in the process, and 2. changing of factor weights and evaluation of their effects on ranking of suitable sites. Our results indicate that uncertain and imprecise data can be safely used in these circumstances given knowledge of how uncertain and imprecise they are and how they propagate during data analysis.
