To fully realize its potential benefits, one needs a clear understanding of its impacts on the system. In this paper, the feasibility of using a simulation model to provide a systematic perspective for manufacturing firms to implement a commonality strategy is demonstrated. Alternative commonality strategies including the stage of employing commonality and the allocation policies are simulated. Several interesting results on effects of commonality, allocation policies, and optimal solutions are obtained. We then summarize qualitative insights and managerial implications into the component commonality design and implementation, and inventory management in a general multi-stage assembly system.展开更多

In particular, the inventory savings are quantified with a mathematical model. The purpose is to assist product deisgn teams to make rational decisions in assigning unique parts or pursuing component standardization. In order to enhance the usability of the model, approximations are made to simplify the model and calculations.展开更多
