A Study on Guaranteed Delivery Time Based Inventory Model of Component Commonality in Assemble-to-Order Systems

摘要

In this paper, we develops a guaranteed delivery time based inventory model of Component Commonality to consider the assemble-to-order environment where components are replenished according to a pull-policy and demand is a function of a uniform guaranteed delivery time. We focus on the dynamics between the guaranteed delivery time and its impact on commonality decisions.Assembling products according to priority with common component is also considered. Based on the mathematical analysis, a conclusion is reached that the effect of component commonality on inventory stock cost can be magnified by compression of guaranteed delivery time. And it set up some rules for inventory stock management with lead time. Numerical examples from a case study with a China automobile corporation are also setup to illustrate the impact of guaranteed delivery time on the role of commonality under different cost structures.
