Measurement of Dyadic Supply Chains Efficiency under New Assumptions Using DEA Models

Walid Abdelfattah and Abdelwaheb Rebai

Background: Relationships between members who constitute a supply chain are mainly based on cooperation in order to achieve better joint performance. Hence, the evaluation of supply chains performance usually depended on the existence or absence of cooperation between its members. However, this should not deny in any way the presence of another type of relationship which also could affect the supply chain performance namely, the dominance relationship. Indeed, each member seeks to dominate other actors in the chain to which it belongs in order to achieve better individual performance. Objective: Knowing that technical efficiency is considered as the main attribute of performance, the purpose of this study is to introduce new assumptions consisting in distinguishing between cooperation concept and dominance concept when measuring the efficiency of supply chains. Methodology: Based on what was suggested, new models using Data Envelopment Analysis (DEA) technique are developed and then applied. Results: Obtained models and results are relevant and show that technical efficiency is sensitive to dominance relationship which could be present between members within their supply chain. Conclusion: Although, the configuration of supply chains considered in this study is limited to a dyadic supply chain, the authors share the conviction that this study provides a basis for the development of models that deal with more complex chains, it also allows a more realistic research of best practices and strategies in order to have better joint and individual efficiencies.
