การพัฒนาระบบวางแผนผลิตวัสดุก่อสร้าง

Abstract

The purpose of this research is to develop the production planning system in construction materials industry to consistent with the customer requirement and to maintain the appropriate quantity of stock inventory. The problem of this case study is an old production planning based experience and expertise of the staff which the result is not consistent with the customer requirement in quantity and time. Therefore, the model is designed for the production planning system. The method starts analyzing forecast information and production planning factors for creates the algorithm in objective minimize inventory cost and apply the sequence method for the highest usefulness. The enhanced system will evaluate from the efficiency of inventory management which the results of this study indicate that the inventory cost decrease 248,794 baht and the stock out rate in each month decrease by an average 38.1%.
