In this paper, the analyzing of performance of a decision making unit (DMU) with twostagenetwork structure has been considered in two directions: at first step, the inpututilization versus output performance has been considered and at second step, the interunitcomparison has been investigated. The problem of comparing DMUs only with eachother in data envelopment analysis (DEA) has some shortcomings, therefore a satisficinggame theory has been introduced to overcome the above mentioned shortcomings in twostagenetwork structure DMUs.
