Why is it important?
A decentralized Bi-level model is designed for a closed-loop supply chain. The robust multi-objective bi-level model is compared with its single-level variant. The deterministic models are compared with the robust models. Cost, work damage, and job opportunity are linked to DMs risk averseness. The DMs attitude toward risk is carefully considered in the model formulation.
Perspectives
The performance of the model is compared with the performance of the deterministic decentralized model and the corresponding multi-objective model designed for the centralized system in both the robust and deterministic modes. Results indicate better performance of robust approaches compared to deterministic approaches. The decentralized approach provides better performance for the cost-sensitive decision-maker, especially the optimistic one, and those who are sensitive to social parameters prefer the centralized approach.
