Agile transportation is one of the most important issues for the resistance of a military-police organization in the operational environment. This study has been done with aim of identifying the gap of importance and performance in the agility indicators of strength and mobility in a military-police organization.

This research is one of the applied research types and is organized with mixed qualitative-quantitative approach. The statistical population of the study is the transportation experts of the studied organization. In the first phase of research, a list of factors affecting the making agile of power and mobility of the studied organization was extracted through interviews with the mentioned experts and analyzing the contents of done interviews. In the second phase, this list is provided to members of the statistical community in the form of a questionnaire and the importance and performance of each identified indicator is evaluated. The data of these questionnaires were analyzed and displayed using the importance-performance gap matrix.

The results showed that the two components of transport personnel’s living condition and the ratio of number of drivers to vehicle (heavy, semi-heavy) were considered as important and primary items for improvement and correction programs, and other discussed components were the next priorities.

Based on the research findings, it can be concluded that for car and equipment be ready to use, the level of users' knowledge in the field of equipment maintenance should be increased more than any other action, and also high-consumed parts should be properly Provided and made available to consumer categories.

One of the important characteristics in the supply chain is the transportation of materials and products between different regions. The distribution of raw materials on each level, like the joints of a chain, connects these levels. Therefore, distribution and transportation have an important role in the cost of products, because improving the vehicle’s route at distribution and transportation of materials and products in the supply chain will reduce the cost of products. In this article with a case study in one of the logistics supply chains of Iran, customer demand is considered and the model of vehicles routing problem is proposed according to the conditions of the company under study, which is a model of routing problems of open vehicles with a timeline. The objectives of this model are to achieve the lowest cost of distribution as well as the cost of quality degradation due to defects in the transportation system and also the optimal size of the distribution fleet to meet customers demand.

method of this research’s studies is library and regarding that these are case study, fields and observation methods are used. To identify the customers and their demands and also characteristics of investigated product and characteristics of vehicles assumed in the problem, reports are extracted from information system of logistic company. To achieve the objectives of this research multi-objective Gravitational Search Algorithm (MOGSA) has been used to solve open vehicles routing problems along timelines. Optimized navigation routing is done regarding the presented descriptions about gravity force. It means that optimization operation is done by multi-objective Gravitational Search Algorithm

The matter that any navigation to serve the customers should traverse which route depends on type of problem which is optimized by multi-objective Gravitational Search Algorithm and regarding the achieved beam front, for the optimized navigation base on algorithm a path will be traversed in which some of customers will be in route whom according to their demands and vehicle’s capacity can be.

To decrease the transportation costs, distribution companies’ requirements to exterior assignment of their products transportation is increasing. When the exterior assignment is done vehicles after loading of products and service, don’t need to return to the main depot and they can return to any of their desired routes after service. In the current study the product distributor company by exterior assignment of distribution operation to another company decreased the costs of vehicle maintenance and amortization into zero and as a result there’s no need to return the vehicle into the main depot.

Each supply chain has internal and external vulnerabilities that undermine the chain's resilience to disruptions. The purpose of this study was to analyze the three aspects of "vulnerable ,disruption and solutions to deal with disorders" with a systematic view of the supply chain of the operational forces of Military-police organization.

This research is applied in terms of purpose and descriptive in terms of data collection method and is a causal-comparative branch based on structural equation analysis. The statistical sample of the study was 20 clothing managers of the studied defense organization who were selected by sampling and snowball sampling. The research instrument used was a questionnaire whose reliability was confirmed by Cronbach's alpha method and its validity was confirmed by research experts. After confirming the validity of the components, based on three hypotheses and by analyzing the interaction of three variables, a conceptual model of the research was presented. This model was evaluated with the structural equation approach and the measurement, structural and general fit of the research was performed.Findings and

By implementing the model, the internal relationship of the three variables of the research with each other was explained. In this model, by establishing the relationship between three aspects of "vulnerability" as an internal factor, "disruption" as an external factor were extracted so that in this model, "dependence on the number "Limited supply" and "excessive complexity" were identified as vulnerable factors in the supply chain, while "Corona outbreak" and "government economic policies" were among the most important disruptions or stimuli affecting the supply chain. Overcoming their effects, solutions to disruption such as "using domestic production capacity" and "communicating to create flexibility in supply and production" were suggested that are not unrelated to effective harms and disruptions of the model.

In recent decades, evaluating and selecting the best supplier has become one of the most important issues for companies. For this purpose, weighting and ranking techniques have found wide applications to solve supplier selection problems. The main purpose of this study is to identify the pure effective criteria in evaluating the performance of suppliers, their weighting and ranking of suppliers of Saipa Company with combination of fuzzy Delphi, Swara and evaluation of additive ratio (ARAS).

The method of the present study is applied based on the purpose and descriptive-survey in terms of data collection. In order to achieve these goals, key performance criteria were first extracted by a comprehensive review of the literature and background. In the stage, by using the fuzzy Delphi technique and due to the limited size of the community and using the opinions of all experts and managers of the company with population of 30, the effectiveness of these criteria in Saipa Company was evaluated and all criteria were approved. Then, using Swara weighting technique and using the opinions of 30 elite people, the criteria were evaluated and their weight (importance and priority) were extracted.

The result showed that the second criterion "elimination of waste" with the highest weight as the most important pure criterion, and the fourth criterion (repeated inspection of materials), the first (supplier cooperation), the third (quality assurance) and the fifth (supply of materials according to industry requirement) are the next priorities in terms of importance in evaluating the performance of pure suppliers. Finally, considering the sensitivity of the ranking of pure suppliers in the company, using Aras decision-making technique and based on the weight of extracted criteria, six suppliers of the company were evaluated by experts and the final ranking of suppliers in terms of performance was determined.

Thus, the proposed approach of this study will help company managers in improving the status of pure suppliers and selecting the best supplier for greater productivity.

The purpose of this study was to identify and prioritize the factors affecting implementation of green supply chain management in Khuzestan province steel industry using exploratory factor analysis and fuzzy AHP.

The results of Fuzzy AHP test to rank these variables also showed that among the variables, customer factors, government factors and financial factors respectively has the first to third priority in terms of importance in implementation of green supply chain management.

According to many experts and researchers expression, a supply chain with a high level of risk cannot be effective in achieving the goals of organization. The growth of environmental hazards and the destructive impact of productive activities on this area also increase the importance of addressing the issue of risk management in the supply chain, which is known as the sustainable supply chain. The main purpose of this study is to design a framework for assessing sustainable supply chain risk.

In this study, by studying the theoretical foundations and reviewing the research literature, a basic framework of dimensions and criteria for risk assessment of sustainable supply chain has been achieved. The case study of this research has been done on the supply chain of 5 car manufacturing companies. Then, using Best and Worst Method technique, the final hierarchical structure for risk assessment criteria is obtained and using Graph Theory and Matrix Approach technique, the results of risk assessment of supply chain of five companies from the perspective of sustainability are obtained.

The research results show that the ranking of companies has been determined from the perspective of the sustainable supply chain’s risk level that SAIPA Diesel Company has the highest rating.

Due to the use of a comprehensive framework, this research incorporates a combination of quantitative and qualitative metrics of risk assessment of the automotive sustainable supply chain and, unlike many studies, is not limited to one stage of the supply chain and covers all stages of the supply chain. This framework can be used to evaluate different parts of the automotive supply chain (primary suppliers, manufacturing companies, distributors and retailers) and measure their risk from the sustainability perspective.

using new and innovative technologies such as blockchain are some of the solutions that in the field of supply chain management can correct the existing inefficient constraints and processes and create positive changes in this field. This study consists of examining various concepts such as supply chain, block chain, balanced scorecard and the original aim is considering the achieved results it should be acted to evaluate and prioritize the effects of blockchain technology on processes and components of supply chains management and Also using the achieved results and the Balanced Scorecard (BSC) template, determine the importance and priority of the counted dimensions.

About the subject of this research which is applied researcher based on descriptive/survey studies has acted and by collecting data with library and field method besides statistical analysis acts to determine the priority and impact of blockchain technology on supply chains processes.

Regarding the nature of supply chain processes and on the other side features of blockchain technology there’s the possibility of using these two phenomena together (because of union) and in other words the scenario of integrating the blockchain technology and supply chain causes the improvement of supply chain performance. Regarding the four dimensions of balanced scorecard evaluation and derived from the research results, at the strategic level "customer dimension", at tactical level "financial dimension" and at the operational level "internal processes dimension" have more priority and importance.
