DEVELOPMENT OF A SUPPORT METHOD FOR PRODUCTION PLANNING BY USE OF STANDARDIZED WORK TABLES

Abstract

As large enterprises have begun adopting multiproduct variable quantity production, smaller companies servicing these large enterprises have been forced to increase the pace of production planning and management work. Activities that effectively improve all functions (kaizen) related to production management hence need to be implemented on site. However, production planning software is not designed to link to standardized work tables used in production worksite management. This study develops a system that can be used in all stages of product development, from production planning to worksite management. We implemented it by adding a production planning function to standardized work tables. This system uses data (items, machines, work in progress, delivery requests, etc.) and object-oriented optimization technology, which allows for the planning of the production schedule with little adjustment to the input parameters. We verified the performance of the proposed system by solving various production-related scheduling problems using the factory simulator QUEST. We used the macro function in Excel to create a standardized work table where the production schedule was properly listed based on the results of planning.
