Among the critical industry problems, one is the supply chain. Among the points, reflecting this importance is the coordination of chain orders. Ordering and supplying any event through optimization models has the potential to become competitive advantage. The point that we never face lack or shortage of inventory plays a key role in different areas. Thus, the optimal model can be operational taking into account all the objectives. The purpose of this paper is to provide a model for coordination of supply chain orders using linear programming. The data was evaluated according to expert opinion and in the form of mathematical equation and Gams software. The results showed that the coordination of contractor and supplier orders is largely in the sensitivity analysis group on the values of the objective functions. Moreover, the proposed model also showed that the optimization of order management and unit earnings profit based on it has functional and developmental capabilities.
