不确定情况下装配制造过程的物料多目标决策

he decision regarding how much and when to order and assemble are main problem for a assembly system, where a number of parts are acquired to produce a single product and the part procurement lead times are vague. The lead time, reorder and lot size are critical factors effecting the collaboration between the successive echelons in supply chain. In this paper, we consider reorder of some parts and lot size with fuzzy lead time for a assembly production , and derive an multi-objective inventory model with fuzzy parameters. We briefly introduce fuzzy theory and propose an interactive fuzzy multi-objective decision-making method for solving the model to give a Pareto optimal solution.
