| This paper focuses on make-to-order production. Since the goal of the sales department is to receive orders as much as possible, they tend to meet their customers?f requirements without considering the productivity of the production department. This results to the unbalanced workload of the production department. Consequently, overtime work happen frequently and sometimes taking more orders may even decrease profitability of the manufacturer. To solve this problem, a production seat system has been designed. Product type (seat type) and quantity of each time period (month or week) are planned in advance so that workload unbalance can be considered. However, no research is conducted on how to prepare the parts for the production seat system. Since the customer desired delivery lead time is often shorter than production lead time, therefor parts need to be prepared the in advance, and now large parts inventory becomes a key issue in the target manufacturers. In this paper, a new seat is designed for the target manufacturers, and parts preparing based on the seat is also proposed. The proposal is compared with the traditional production method and is confirmed to be effective on reducing parts inventory. |
