PURPOSE:To detect beforehand the day exceeding an allowable range, and to issue a caution by obtaining the stock transition for showing the time sequential variation of the stock quantity by an information processing means. CONSTITUTION:A CPU 11 executes the control of the whole EWS (engineering work station) 10 and an information processing related to production planning, based on a control procedure stored in a system memory 12. Also, the CPU 11 calculated the day when the stock quantity show by a predictive stock transition reaches the lowest stock quantity and the safe stock quantity of each kind determined in advance, that is, the minimum out-of-stock day, the safe out-of-stock day and the stock quantity at that time. The CPU 11 in the case is operated as a third information processing. This processing is attained by comparing the stock quantity of each day the predictive stock transition with a prescribed value. The calculated arrival day and the minimum stock quantity, and the safe stock quantity are displayed together with a kind name on a caution board on a display screen, and a caution is generated. Accordingly, a CRT 16 in this case is operated as a warning means. |
