Introdution: It is very important to pay attention to the health centers and their roles in countries. Improving the performance of these centers is dependent on their performance evaluation. The aim of this study was evaluating the relative efficiency of health centers with a combined approach of DEA and GT.
Methods: For this purpose, first by reviewing relevant researches, inputs and outputs associated with the operation of health centers were identified and with a field study, the variables were matched with forms and information resources available in the health center data base. Then, by visiting experts from different functional areas, performance criteria were fitted with proportional data. After data gathering, mathematical modeling has been prepared based on the hybrid DEA-Game techniques. The DEA-Solver and Lingo software, mathematical models were designed and solved.
Results: Results showed that performance levels among health centers in Yazd City are different. With reprogramming the resources that was affected the performance of health centers, included the number of employees and their covered population it has expectd an improvement in their efficiency.
Conclusion: Managers and policymakers of health care centers can use the model presented in this study to measure the relative efficiency of these centers and to improve their efficiency.

Keywords: Performance management, Technical efficiency, Data envelopment analysis, Game theory, Health centers.
