Efficiency evaluation of sustainable supply chains with supply contracts

L. keshvardoost-Masooleh, F. Keshavarz-Gildeh

Abstract



Supply chain sustainability along with profitability and social and environmental requirements are among the most widely discussed topics of the organizational management literature. Supply contracts are useful tools for improving coordination between various members of a sustainable supply chain. The efficiency evaluations conducted with the Data Envelopment Analysis (DEA) fail to consider the potential impacts of these contracts in sustainable supply chains. This paper evaluates and compares the efficiency of a three-stage sustainable supply chain and the efficiency of each of its stages before and after introducing a number of contracts to the relationship between stages. These evaluations and comparisons are performed to determine the impact of contracts on supply chain efficiency. To illustrate the performance of the proposed method, it is applied to an example of nine tomato paste supply chains.
