Among the most significant management and policy-making elements is improving the efficiency of businesses and companies active in various parts of the industry, as well as management processes and systems. Various methods and models have been proposed to measure the efficiency of firms, processes and systems in a sector. One of the most important models used is network data envelopment analysis, the most widely utilized in measuring the efficiency and productivity of businesses, processes and systems. This is founded on mathematical programming and moreover is among the most powerful techniques for performance evaluation and optimization. In this study, while mathematically modeling and measuring the performance of the study sample, utilizing dynamic network data envelopment analysis, a suitable model for measuring performance, taking into account the stability of the conditions, was designed to be a framework for leading the system to higher objectives. Via utilization, it provides the basis for improving and reducing the adverse effects of the system. Therefore, the data envelopment analysis model in this research is designed as a framework for measuring, analyzing and promoting activities at the network level with the game theory approach as well as in uncertain conditions. Executives/managers will be able to understand the strengths and weaknesses of the system to strengthen and eliminate existing weaknesses plus undertake requisite planning and actions.
