Recently, based on the opinions of many researchers and experts, the competition in the corporate level has changed into competition in the supply chain level. An efficient and agile supply chain is considered as a competitive advantage and decisive in the field of competition. Therefore, many researchers argue that as competition shifts from the corporate level to the supply chain level, the quality management and quality as a result should also expand from the corporate level to the supply chain level; So that supply chain quality management can help a company to coordinate the uniform execution of all activities in the supply chain to ultimately improve its performance. The purpose of this study is to investigate the effect of supply chain quality management practices and capabilities on operational and innovation performance in Mashhad Food Industry companies. In order to do this, after reviewing the literature and identifying indicators, standard questionnaires were distributed among 340 active managers in Mashhad food industry companies and according to Morgan table, 181 samples were selected from the completed questionnaires. The research method is applied in terms of purpose and descriptive-survey in terms of data collection. To test the hypotheses and answer the questions, structural equation modeling was used. Finally, by confirming the research hypotheses, it was found that the capabilities and supply chain quality management practices affect the innovation and operational performance.

This study examines the contracts used in the supply chain. 74 international articles from year 2004 to 2021 and 7 recently published Persian articles in the field of supply chain contracts have been studied. According to the classifications, it has been concluded that the most used contract in the supply chain for coordination is the revenue sharing contract with a frequency of 35 articles. It has been observed that in 58 out of 81 articles, the game theory approach has been used, in which Stackelberg's approach has the highest number of articles with 39 articles. Most articles (74 articles) seem to prefer a two-tier supply chain, due to their limitations. One of the most important results was that sometimes each of the contracts cannot coordinate the supply chain lonely, but a combination of them leads to the coordination of the supply chain.

The pattern of change and evolution of maintenance in Iranian industries is influenced by the characteristics of public administration and the oil-based economic structure. On the other hand, the mechanisms of sanctions and inflation have changed the behavior of Iranian industries compared to other countries over the years. Today, with the introduction of new issues such as the industry 4.0 and the importance of some national issues such as the resistance economy, there has been an effort so that the industry can develop in a predictable, desirable and logical way. Therefore, maintenance models that are developed must be able to respond to certain economic conditions such as the case in Iran and can be implemented correctly. In this article, in the first step, a review of maintenance excellence models was conducted to achieve the design method of maintenance excellence system in Iranian industries. This article does not cover the comparison of these models. Then, by examining the factors that should be considered in Iranian organizations in developing a maintenance system, the emergence of various equipment maintenance systems in the country were addressed to provide a useful knowledge of these systems. Then, the proposed framework for maintenance excellence based on the concepts of asset management in Iranian industries, entitled "Irim 3", was presented, which in addition to full coverage of ISO 55000 standard clauses, is compatible with the components and characteristics of Iranian industries and has been implemented, developed and updated in a number of Iranian organizations. Then, the method, concepts, principles of evaluation of the organization, requirements and specifications of preparing a suitable roadmap for excellence, according to the characteristics and components of Iranian industries were introduced. At the end, the general structure of the proposed framework was displayed and the coverage of ISO 55000 standard clauses was described. By implementing this framework in various organizations and industries, the key performance indicators were maintained and also the result of the audit of the organization's roadmap was significantly improved, which proves the efficiency of the framework according to the local conditions of the country.

The aim of this study was to provide a model for evaluating the performance of police logistics management in disciplinary crisis. This research is applied-developmental in terms of purpose. It is a qualitative research approach and is related to the method of interviewing experts and specialists. The interviewees in this study are in two groups: professors of Amin University of Law Enforcement Sciences and heads and managers of the Departments of logistics support, Special Unit, Relief Unit and FATEB Prevention Police. Also, due to the necessity of using opinions of experts, purposive sampling method has been used and the sample size was determined as 13 people. The research data was also analyzed using the thematic analysis method. The results show that the model for evaluating the performance of police logistics management in disciplinary crises is significant in 6 dimensions including: forecasting, supply, agility, organization and management, science and technology and preparedness, and 17 components including: vehicle, welfare, weapons and ammunition. Automotive and fuel, commodities, rations and clothing, readiness, agility capabilities, agile management, supervision and control, manpower, planning, coordination, culture and structure, training and skills, technology information and communication, maintenance, repair and operations, warehousing and logistic support and 66 indicators as a subset of the components described..

The purpose of this paper is to identify and analyze supply chain operational disruptions of a defense organization through interpretive structural modelling. In the first step, by reviewing the literature, supply chain-related disruptions were counted. Then, by conducting field research and consulting experts, disruptions appropriate to the operational clothing supply chain of a defense organization were identified. Then, by using interpretive structural modelling (ISM), the degree of dependence and stimulus of disruptions and their internal relationships were obtained in seven stages. Disruptions related to MICMAC analysis were classified into four categories: autonomic, dependent, connective, and stimulus. According to the results of this study, the disruptions of "war and terrorist attacks" and " Coronavirus outbreak " in the fourth region, have the most influence and actually stimulate the rest of the disruptions. Six of the disruptions were located in the first region, the autonomous region, and "delayed delivery" disruptions was the most dependent possible disruption in the second region.

Warehouse, as the main link in any large and complex organization, establishes a direct relationship between different parts of the organization and the supply chain. Today, the warehouses are designed to be built in such a way that they can speed up various warehouse operations. Therefore, it is important to attempt to move toward the just-in-time system. Adaptation to this system requires distribution centers. One solution is to use a        cross-dock. In this article, the optimal retail cross-dock layout is investigated by considering distribution operations as JIT. Layout is defined as the allocation of warehouse floor space to retailers. In this regard clusters of the warehouse floor locations are considered to assign to different retailers. Each cluster includes a group of multiple neighboring floor locations that are adjacent to each other and placed one after the other. Products are picked up at the receiving docks and are transported along with the warehouse up to the location where the products for a given retailer are located. The purpose is to determine the allocation of warehouse floor locations to retailers to minimize the distance traveled in the warehouse. Different scenarios for layout of the warehouse have been studied and analyzed. An integer linear programming model is presented and the Benders decomposition method is also used to solve the problem and the results are presented. Finally, ideas and recommendations are presented to develop the model.
