For a product at mass production stage, the standard working-hour is set up in advance. However, the actual working-hour may not be equal to the standard working-hour. In addition, so far in the product sample development stage, PVT (Prototype Verification Test), EVT(Engineerings Verification Test) and DVT (Design Verification Test ) are not considered for defining working hours. This research applied the methodology of Case-Based Reasoning (CBR) with practical cases in the past to estimate working-hour and cost of the products. The estimation system of working-hour and cost was constructed based on power supply products. The system can be applied to various product models flexibly to obtain their working-hours and cost in total. When gathering required information for the system, our considerations including production line setup, part assembly process, but excluding uncertain factors suchas different skill levels of workers, special assembly process for parts, reworking for the reason of engineering changes, etc. Based on the considerations, we derive several mathematical equations to model the estimation system of working-hour and cost. Finally, we implemented the model by applying Excel and Access tools. The system can be used as references for product development, production line scheduling, budget preparation, etc. Furthermore, the results from the estimation system were compared with the actual process to analyze exceptional situations and their working-hours.
