A Case Study for Manufacturing Information System Design in Make-to-Order Production

수주생산방식에서 생산정보시스템 설계방법에 관한 사례연구

This paper deals with the design of the manufacturing information system which is able to respond rapidly to various requirements of customers in make-to-order environment. The system is required to maintain a consistent flow of information from the start to the end. For this, we adopt an approach based on Information Engineering (IE) methodology, which consists of four stages: planning, analysis, basic design, and detail design. The first is a planing stage which establishes a project goal and organizes a project team. In the second stage, current activities are analyzed and problems are defined. The basic design is accomplished in the third stage, where a project scope is defined and an overall feature of the new system is presented. And then, in the last stage, the operation plan of each subsystem is drawn up in detail and all subsystems are integrated. This study applies the methodology to the case of H company and focuses on designing forms which are easy-to-write, easy-to-understand, and field-oriented. These forms are interrelated and can be used for systematic analysis and design. By applying them to the system design, we have obtained effect of reducing cost and time.
