Collaborative Planning in Supply Chains by Lagrangian Relaxation

Abstract

A collaborative planning framework based on the Lagrangian relaxation method is developed to coordinate and optimize the production planning of the independent partners linked by material flows in multiple tier supply chains. Linking constraints and dependent demand constraints were added to the monolithic Multi-level, multi-item capacitated lot sizing… (More)
