Integrated performance and stability analysis for VMI supply chains using multi-resolution hybrid models

Performance and stability issues of a supply chain are synthetically considered in this paper. An integrated two-level VMI-HPP architecture consisting of multi-resolution hybrid models is proposed. Techniques to synchronize these hybrid models across different levels are developed. The aggregate level performs planning across the supply chain, where performance and stability issues are concurrently addressed with non-linear optimization and systemdynamics techniques. The detailed level performs scheduling at each chain partner using non-linear optimization and discrete event modeling techniques. The distributed models are integrated under HLA infrastructure. Performance of combined cost and stability analysis is appraised against a method considering only cost.
