To plan a component inventory schedule by setting the volumes of component inventories of a product whose demand varies greatly and a product whose demand is hardly predicted.
Component information of respective machine kinds and machine kind information are inputted, a component-classified invertory calculation rule determination support means 101 simulates the necessary amounts of components, and a component classification rule defining means 113 determines a component classification rule 108 for classifying the components on the basis of the volumes of inventories of the components for classifying the components. The respective components are classified according to the component classification rule 108 and held as component classification results by a component classifying means 102, a manual adjusting means 103 supports the correction of the classifications of the components, and the correction result is held as the component classification results of the components in the component classifying means 102; and the component-classified inventory volume calculation rule 109 for calculating the volumes of inventories of the respective components is determined by the component classifying means 102 according to the component classification results and a component inventory volume setting means 104 determines the volumes of inventories of the components.
