An Introduction of a Cost Estimation System for Model Changes

In order to be cost competitive in the consumer electronics industry, it is needed to estimate product costs earlier in the design phase. In this study, we reviewed quality and quantity cost estimation techniques to develop a cost estimation system. The qualitative cost estimation technique is used to store expert's knowledge in the form of rules or a decision tree, and quantitative cost estimation techniques is used to extract a similar cost basis based on historical cost data of products. Also, we developed a cost comparison system using these two methods.
