| Outline of Final Research Achievements |
This study focuses on engineer-to-order (ETO) manufacturing firms which need to provide customized products in short due date. Because parts need to be readied before orders arrive, high parts inventory and low order-received rates always form the bottleneck to efficiency. To solve this problem, a new operating system applying the concept of “production seat booking system” is developed. Order-receiving schedule of each product functional specification items are represented as “seats”, such that salespeople can easily check whether a vacant seat is available and then quote an accurate delivery due date to their customers. Methods of preparing parts by using the future inquiry information, and predetermining order-receiving plan to utilize the available parts are proposed. The effect of the proposed operating system on both increased orders and reduced parts inventory are confirmed.

| Academic Significance and Societal Importance of the Research Achievements |
見込み生産や少品種の受注生産にしか生産座席方式が適用できていない現状に対して，製品「機能項目・性能区分」単位で座席を定義することを提案し，超多品種でも座席方式を適用できるようにした点では，学術的に意義がある．また，部品消費実績の代わりに引き合い情報を活用した部品手配量見積法を提案し，その上，手配済み部品の活用を考慮した予約座席の設定方法を提案し，座席方式を用いない受注方式に比べ，失注と在庫両方を低減できることを数値実験で確認した．当方式の利用によって，対象企業が抱えている部品過不足による失注及び膨大な部品在庫問題を解決可能なこと示せたことで，産学両方にとって意義があると考えられる．
