a proposed model for the assessment of supply chain management using dea and knowledge management

Supply chain management (scm) is an integrated system of planning and control of materials and information, including suppliers, manufacturers, distributors, retailers, and customers. chain performance measurement is an important issue in scm. also, given that the information plays a key role in improving supply chain performance, the kind and amount of information sharing should be investigated. in this paper, the effect of information sharing on supply chain performance will be evaluated. in this way, 17 different scenarios of information sharing are defined and ranked using the cross-efficiency method. finally, values ​​for different scenarios using simulations and rockwell software arena v5 are reported. the obtained results show that the proposed model is quite valid and efficient and can be easily applied to real-world cases.
