Method of and system for order amount calculation

Abstract From the Canadian patent

An order amount of parts can be calculated from an actually used amount of the parts, so that the used parts can be resupplied subsequently. An order amount can also be calculated form a production plan, so that the parts necessary to meet the plan can be delivered. In this technique an order amount is calculated by the, equation "W1~X' + W2~X2" where X1 is the order amount, calculated in a subsequently resupplying way X2 is the, order amount calculated in a plan correspondence way W1 is, an actual weight, and W2 is a plan weight. The actual weight W1 becomes high and the plan weight W2 becomes low when the subsequently resupplying way is suitable and vice, versa. The actual weight W1 and …
