Aim and introduction: The Ministry of Defense and Armed Forces Logistics is responsible for the planning, coordination, support, and expansion of the defense power; this ministry is responsible for equipping the defense forces to encounter the possible threats. The ministry has been subject to international sanctions and pressure due to the production of defense industries. It is imperative that the defense industry, following the creation of restrictions that prevent them from carrying out their inherent missions, seeks a change of course in order to maintain the level of its products to meet the needs of its customers. In this regard, it is necessary to know the exact problem and its aspects, to consider a suitable solution in this regard, considering that the defense industry in each country is part of the governing industry, so it is important that this issue is explored centrally. One of the important ways to do this is to use the capabilities and capacities available in networking. This approach is done by creating supply networks, product production, storage, and even timely distribution, outside the organization's borders and is used to use the final product. Network organization is placed between the two ends of the market and the organization. The important issue here is how to get things done in the heart of the network. Based on the findings of this study, this is done by agencies. One of the theories that can explain some of the costs and problems in a variety of financial contracts is agency theory. This theory has been widely used in many fields such as economics, management, finance, accounting, and even politics. This theory is closely related to game theory and deals with issues arising from the conflict of interest in bilateral or multilateral relations. The model seeks to exploit the capabilities of networking to address constraints and crises, taking into account the concepts of supply chain theory and agency theory at the same time as how to use existing capacities and capabilities beyond the organization's boundaries and to organize the network of industrial agencies to supply parts in the final product in accordance with the order of the stakeholders. Methodology: Based on the findings of this study, this will be done by the representatives of the organization using the theory of agency. The method of this research is fundamental and applied, and the model of this research, considering the concepts of supply chain and agency theory simultaneously, intends to use the strategic model of utilizing existing capabilities beyond the organization's borders and organizing the network of industrial agencies. In this approach, the goal is not only to reduce costs but also to increase the willingness of the parties to the relationship between the owner and the customer. The proposed model is a variety of multi-objective decision-making models and the fuzzy multi-objective decision-making method has been used to solve the model. Findings: According to the results obtained from the conducted studies, the average utility of the organization is currently 19% of other different parts. Based on the model’ s result, it can be said that by changing the resource allocation, the owner utility can be increased by 60%. Therefore, it can be claimed that the method of allocation in this model leads to improvement in the organization’ s situation. Discussion and Conclusion: This study is research, considering the concepts of supply chain and agency theory simultaneously, intends to use the strategic model of utilizing organizing the external network. The conclusion of the research show that increasing the financial resources will not essentially result in the increase in the utility of the members of the supply chain and the actors in the relationship between the owner and the agency but the method of optimal allocation of the resources and proper assignment of the tasks to the agency can increase the Satisfaction of the parties of the owner-agency relationship. Therefore, it suggested that the mentioned organization execute the model in the research by using the predicted parameters for the next year and accordingly, regulate the budgeting related to the member of the network. Furthermore, the organization is able to change the input parameters in the center of the different scenarios based on the model’ s sensitivity and measure it and make stronger decisions based thereon. In order to conduct the future studies, it is recommended that the researchers who are interested in this topic, measure the effect of the allocation of other resources such as information, knowledge share, equipment and tools and so on in addition to the financial resources and formulate the relationships related to its effectivity on the utility of the members. Also, it is recommended that the future researchers identify the possible scenarios for the future using the integration of the futurism methods and calculate the Pareto solutions by using the proposed model of this research and obtain the final answer of the model.
