Today, the most important characteristic of organizational environments is rapid change, which has caused complexity and reduced the power of organizations in predicting future events and has challenged them on the path to success. In such a situation, an organization alone cannot cope with the complexity and competition. By drawing a new space, the cooperation network has provided the ground for strengthening innovation and increasing competitiveness and survival in the environment for the organization and reduces the existing costs and risks. But what does a cooperation network look like?

The present study, following the design of an effective cooperation network model in the Institute of Defense Industries, has identified the dimensions, components and influential elements. In this regard, taking advantage of the existing literature in the field of networks, the basic concepts are identified and using the data theorizing method of the foundation and interviews with experts, professors and defense managers related to the subject, open, pivotal and selective coding has been done

based on the coding, the factors and elements of the model are identified, the model extracted from this research,comparing with previous research, has a more comprehensive look on investigating the various sections.

finally, network performance demensions and effective achievement include network structure, network process, network members, nature and topics of cooperation, the conditions of extended cooperation, motivation of network founders and motivation Network Partners has developed a network of cooperation in terms of the range of elements of interest in the defense industry.

The main purpose of this study is to identify and prioritize the indicators affecting the Supplier’s selection in LARGT Supply Chain

data were collected in two stages (qualitative and quantitative) using the Sequential Exploratory method.  Initially, through interviews with 11 experts who were selected by theoretical sampling method, Components were identified in the qualitative section, using the Delphi method, 18 panelists reached a consensus after 4 rounds.The validity of the qualitative part was also confirmed by Kendal coordination coefficient (k = 0.79) Quantitative data analysis method was implemented in two descriptive and inferential levels through SPSS and Lisrel software

Based on the findings of the qualitative stage of the questionnaire, a quantitative section was designed and after measuring the validity (factor) and reliability through the participation of 120 managers of Shahrekord food industry, 102 of them were selected by random sampling method Experts identified the key components in the form of 85 key concepts and 5 main criteria, which include: pure, "agile", resilience, green and sustainable talent, with the highest Friedman score of 44.72. And the lowest score is related to the "agile" criterion with a value of 40.65

The simultaneous use of these five approaches provides coverage of the weaknesses of the approaches.

5s (sorting, adjusting, shining, standardizing and maintaining) are pure tools known to improve system performance. In the present study, the short-term dynamic consequences of the 5s sorting aspect are investigated using the system dynamics approach. To determine the effect of sorting activity on throughput production, a system dynamics model is simulated and developed, which is investigated in this study. The primary goal was to evaluate system performance results when improving 5s performance. The simulation results were a stimulus for system improvement in real conditions. Because the simulation results were able to mimic the real situation. As long as the simulation results show further performance improvements, the model developed in the present paper can be replicated in other cases, because the variables used in the model are general and common to many types of production systems, especially New in pure methods. Dynamic analysis is not common in 5s practices. This study also reveals some interesting relationships between the 5s and other lean practices and system performance.
