Abstract:
1. An inventory management system implemented by an information processing apparatus, the system comprising: an ordering-required-quantity-data storing unit that stores an ordering required-quantity of a product previously forecast, the ordering required-quantity incorporating a market demand forecasting value and a safety inventory quantity; an order-entry-actual-achievement-data storing unit that stores an actual order quantity of a product for which order entries have been placed; a market-demand-forecasting-value calculation unit that calculates a market demand forecasting value based on the actual order quantity stored in the order-entry-actual-achievement-data storing unit; a correction quantity calculation unit that acquires the actual order quantity from the order-entry-actual-achievement-data storing unit, acquires the ordering required-quantity from the ordering-required-quantity-data storing unit, and calculates a correction quantity for a safety inventory quantity of the product based on an error rate, wherein the error rate indicates an error of the actual order quantity to the ordering required-quantity thereof and becomes negative when the ordering required-quantity is larger than the actual order quantity, and positive when the ordering required-quantity is smaller than the actual order quantity; a reference safety inventory quantity calculation unit that calculates a reference safety inventory quantity based on market demand forecasting of the product; a determined safety inventory quantity calculation unit that calculates a determined safety inventory quantity, which is a value obtained by adding the correction quantity calculated by the correction quantity calculation unit to the reference safety inventory quantity calculated by the reference safety inventory quantity calculation unit; and an ordering required-quantity calculation unit that calculates the market demand forecasting value, which is a value obtained by adding the determined safety inventory quantity calculated by the determined safety inventory quantity calculation unit to the market demand forecasting value calculated by the market-demand-forecasting-value calculation unit, wherein the correction quantity calculation unit calculates the correction quantity based on a unit price of the product.
