The performance measurement of supply chain with network DEA

Many of researchers and strategists believed that essence of occupation in the 21 century have been changed, and this changing would be endured with ever-increasing speed. Witness of this claim changing of produce-based work to service work and changing of old economic strategy to network economic. One of the new network economic model, is supply chain management that as collection of ways- is about management and coordination all of supply chain management. The supply chain including different dimension that to attentive to great effect in the total organization efficiency, always to notice to evaluation. Now a day's one of the ways that has great utilization in this field is a network DEA model. In this research for calculating one of the networks of supply chain, considers15 chains that including two stages, supplier and producer, and with complicated actions and reactions that to exists in the supply chain, we consider three difference to introduce in the concepts of centralism, decentralism or mixed method. In this research efficiency each one of the chain was calculated under this three control of supplying chain, then will have examine the results of each one and relation between this three controls mechanism, and at the end will be compared with classic DEA model.
