One of the challenges facing the cement industry today, managing the supply chain. Lack of supply chain management, the cement industry has serious problems volatility and the price difference by the manufacturer and the retailer has faced. Usually when a lack of resources and goods in a retail occurs, the customer may go to another retailer. This phenomenon is often called the customer search behavior. This study analyzes a manufacturer and two retailers in a two-echelon supply chain using game theory (Nash equilibrium, balance Stackelberg) with the customer market approach to fars cement industry. The method for the purpose of collecting data item. Enjoying the view of experts, information available on the main site Fars and determine the parameters of the model and software Mathematica functions to solve mathematical equations and plot discussed. The results of this study show that with current conditions and utility functions defined for the issue, to determine wholesale prices for producers in order to maximize profits Is not their own, so the manufacturer must consider market conditions to determine the wholesale price.

In today's competitive and global economy, the life and activity of the organization is determined by the ability to compete and adopt the most appropriate policy against environmental changes. In this regard, the knowledge about the performance of all aspects of the organization is vital for management decisions. Although extensive studies has been carried out in evaluating the performance of organizations through the balanced scorecard (BSC), but there are defects such as focusing on a one-way causality, ignoring the replacement between indexes and between the four-way, and equality between weighted value of indexes. In the present study, focusing on the casual relationships between factors and also between the direction and strength of these relationships, we tried to improve the balanced scorecard method. To do this, first all the relationships between the four dimensions of BSC were determined using fuzzy cognitive map, and it was then used to obtain a network structure, which was used later to create a network data envelopment analysis (NDEA) model. Finally, this model was used to evaluate the performance in Maskan Bank of Fars province. The results show that between 82 branches investigated, 15 branches were efficient and the others inefficient.
