For performance evaluation of supply chain, having a comprehensivemodel with reliable data is useful. This can help to improve the entirechain. In this paper a model is presented, according to the nature ofnetwork and multi-stage supply chain, that able to evaluate theperformance of the entire chain in the form of a mathematical modeland using the financial, knowledge, participation and responsemeasures of the supply chain. In the first part, Indicator sat threelevels; strategic, process and operational, considered and survey themodel verification with Factor Analysis. In the second part, Networkdata envelopment analysis model is used. This paper is the result ofresearch related to supply chain of pharmaceutical companies inTehran Stock Exchange and 115 expert sand senior executive shavebeen questioned as sample. There search results show that strategiclevel with a weight of 0.98 is the most important performance leveland Process and operational levels are respectively 0.97 and 0.87weight. 4chainsof 28 chains studied, have a complete performance and0.43 is the lowest observed performance.
