Outline of Final Research Achievements

To solve the problems of frequent specification changes and large parts inventory in Engineer-to-order companies, a support system using "production seats" is developed for the sales department to accurately propose product specifications and for production department to prepare parts in advance. Usually, production seats are prepared for each single product. However, this seat unit is not practical for the ETO companies because they need to provide enormous types of products for individual customers. Therefore we propose to use the product functional specification items to prepare production seats. To achieve this aim, customer requirements and product functional specifications are abstracted. Parts demand calculation methods are also developed by using the seats information of product functional specification items. The effects of the support system on decreasing specification changes and parts inventory are confirmed by numerical calculations and a case study on drilling machines.
