PART ORDERING AMOUNT CALCULATION DEVICE

摘要

A part ordering amount calculation device uses an ordering amount calculatio n method (S16, S18) for calculating a comparatively short-term ordering amount according to an actual stock amount so as to reduce the stock amount and obtain a stable part supply and an ordering amount calculation method (S22, S24) for calculating a comparatively long-term ordering amount according to a temporary stock amount (stock amount calculated according to the past production) so as to obtain mass production effect. The part price is compar ed to a predetermined price and according to the comparison result, one of them is selected (S14). Thus, it is possible to easily modify the part ordering amount calculation method for each of the parts and to obtain the merits of the two different part ordering amount calculation methods.
