PURPOSE:To attain the fine stock control by obtaining the stock correction value from the planned stock-in and stock-out values to perform the stock control based on said stock correction value and also to secure the margin time for monitor of the stock. CONSTITUTION:The dynamic stock correction value is calculated for each sample time point from the total value of the planned stock-in value obtained with every on-the-hour defined as a sample time point in case each product is supplied in a fixed cycle and the planned stock-out value set at a planned stock-out time point in case a certain number of products are stocked out at one time. Based on said stock correction value, the initial stock value and a fixed common difference are added for calculation of the proper stock value. This proper stock value is stored in a production/stock controller, etc. While the actual stock value is compared with the proper stock value to monitor the stock abnormality. Furthermore no stock abnormality is not finally decided in case the proper stock value is recovered within a fixed margin time even in case the temporary stock abnormality is detected. Thus no stock abnormality process is carried out. As a result, the confusion can be avoided on a production line. |
