PURPOSE:To effectively estimate the time of delivery by obtaining this time via a 2nd arithmetic unit from the time calculated by a 1st arithmetic unit based on the quantity of products and displaying the obtained time of delivery. CONSTITUTION:A ROM 8 stores the time required for the pre-processing operation, the working processing operation and the after-processing operation respectively for each product that can be produced at a plant. At the same time, a RAM 9 stores the quantity of each ordered product and the progress of each working process of products. Then the type and the quantity of a product ordered newly are inputted via a keyboard 2. The time of each process is read out of the RAM 8 in response to the type of the product inputted from a 1st arithmetic device of a CPU 1. Then a 2nd arithmetic unit calculates the time of delivery of the new ordered product based on said time read out of the ROM 8 and the quantity of said ordered product. The obtained time of delivery is displayed on a CRT 7. In such a way, the time of delivery is effectively estimated for a product ordered newly. |
