Proposal of Production Forecast in Demand-Synchronized Production

For demand-synchronized production, it is essential to secure manufacturing lines and facility to be required and keep required components on a steady basis. To achieve this, predicting the peak of future order is the key. Proposed on this paper is a method to predict future production volumes from the results of analysis of the past order data and determination of their similarity by Fourier analysis. When we examined a production forecast using the actual data, the peak-to-valley match rates, which indicate agreement with order peaks, were raised to a significant level. As a result, we can say it is possible to predict required production volumes in several days advance with sufficient accuracy. Wasted inventories could be decreased by better component arrangement. Furthermore, manufacturing facility could be arranged earlier and production load could be effectively adjusted with other manufacturing lines. Efficiency of the manufacturing facility in the entire factory would be largely increased.
