In this paper, the planning of items supply in chain of supply in a military logistics system is investigated. We seek to determine the amount of each required item of logistics system of any supplier which should be provided in each month. For this purpose, a mathematical model is presented with two target functions. Since in a military logistics system, timely delivery of items is very important, first target function minimizes the timely delivery costs (including maintaining & deficit costs) and purchasing logistics system. Second target function minimizes the cost of transportation and logistics system suppliers as the other factors of supply chain. This mathematical model will be solved by MODM method and decides about the policy of supply and transport of required item for logistics. Finally, issues related to the implementation of model and its advantages and disadvantages will be presented.

A review of previous studies shows that even though many research have been conducted in the field of transport and routing, but transport in military logistic systems take small proportion of these studies. On the other hand, transportation issues are broad and with various goals, different shipments and transportation vehicles and time varying parameters, they take various forms. Nevertheless, existence of different mathematical straits could also increase the problem's complexity.The current study is a part of actual issue which has many different goals, different shipments and transportation vehicles, time varying issues, different straits and different ports and final and middle destinations. This study tries to provide a model for the transportation issue of logistics systems. Then it will review and analyze the proposed model through solving of a numerical example. In this section, the effort is to show the application of proposed model, in this regard, we first explain the example and then with use of preliminary phase this will be converted to a network model, then the extended mathematical model will be written and with the use of one of linear programming software it will be solved and finally the answers will be provided.

Increasing competition, market development and business environment, have changed the methods of supplying items and relationship between buyers and suppliers. In these new circumstances, it is necessary to enhance the relations between suppliers and develop collaborative and sustainable relationships with them in order to decrease the expenses and increase flexibility when faced with market changes. In this regard, some of the largest global software companies have presented effective and comprehensive solutions such as Suppliers Relationship Management and have made significant improvements. But creating such systems has been mostly due to the increased reliance on contractors and suppliers in organizations. To increase profit, companies should select an appropriate supplier in the minimum time, thus increasing strategic relationships with suppliers and establish effective interactions with them. Supplier’s Relationship Management systems must provide tools to develop such interactive, extensive and strategic relationships. These systems manage the procurement process and strategic supply within and between organizations. Experience has shown that successful companies and organizations are those whom succeed to establish strong and stable relations with their suppliers.Considering the importance of the aforesaid, in this article we set out to investigate the latest findings about the Suppliers Relationship Management system, its components, processes and benefits of its application in organizations and also we would express its role in logistics and chain of supply.

Nowday the supply chain management is a strategic issue for integration and collaboration of performance of organizations which are creating value for customer in different industries. Without taking a proper approach, the integration and collaboration that are the basis of supply chain management, will be uneffective. So achieving to unique and solidary approach for managing different performances of supply chain, aligning with competitive strategy and proportionate to functional and operational strategies, is important and inevitable for long term success. So according to above points, developing processes which can provide a rational and systematic approach to formulation of supply chain strategies, and implementing them is necessary. Thus this research after reviewing proffered methods in literature and analyzing them, using the value focused thinking logic, tries to structure the objectives of supplu chain and then presents a framework for developing strategies in suuply chain systematically.In this research afer explanatition of aforesaid framework, has presented a process for formulation of supply chain strategy and determining strategic focus points of supply chain via a MODM model. Also implementation of thease strategies, which is one of most important challenges in this context, has provided via determining target of relevant measures. For ensuring intended fitness and alignment and monitoring of real trends with adoptioned strategies, has presented a mtrix which controls fitness ofcompetitive strategy asnd formulated supply chain strategies. Proposed process has explained in a real example about supply chain of a radio active drug.

In this study according to the scientific basis of SCM in the military section, which relies on Maximizing the weeknes and maximazing power of frendly forces enemy, we provided a modele due to evaloating and selecting annunition providers. In accordenc to this reason, after diagnozing and providing provides with deseining modale and using MADM metod, it is mention their method of evaloation in Asymmetric battles.The objctive of this study summerizing in choosing suitable ammunition provider and boosting SCM, varid from producting industries to armd forces, upon a doctorin of Asymmetric battles

Evaluation of operational readiness of organizations to carry of assigned missions is one of key criteria in management general decision making, especially in military organizations. Level of readiness can be related to allocate budget, purchase of equipment and support suppliers in addition to deciding about military and political actions in war or peace time. In this process, availability of equipment is one of the basic requirements in operational readiness of organizations. The main purpose of the repair and maintenance systems and the reason of its existence is logistical support of organization. So presentating a model for evaluation of equipment readiness in the maintenance system gains higher importance.In this essay which is a result of scientific research, the definition of equipment readiness and available models in scientific literature will be reviewed. Then in the view of organizational requirements and research done, the designed model will be described in the form of a system. In this system Readiness evaluation is based on importance, weight and their priority of each supply systems in the mission statement. Also Considering expertise views in the field of age, after sale services and the quality of maintenance will present a fuzzy expert system. Finally, a model for predicting equipment readiness with the respect to environmental and practical criteria has been designed and presented by using Neural Network.
