The first safety stock quantity calculation unit 81 calculates the safety stock quantity of the product at the time of the first passage, which is the time when the unit delivery period, which is the unit of the delivery interval, has elapsed from the time of one delivery. The second safety stock quantity calculation unit 82 is the safety stock of the product at the time of the second passage, which is the time when the cover time, which is the period obtained by summarizing a plurality of unit delivery periods determined according to the product from one delivery time, has elapsed. Calculate the number. The recommended order quantity calculation unit 83 calculates the recommended order quantity of the product based on the safety stock quantity of the product at the time of the second passage. When the second safety stock quantity calculation unit 82 predicts that the number of safety stocks at the first elapsed time is less than the number of stocks at the first elapsed time, the safety of the product at the time when the cover time elapses from the first elapsed time. Calculate the number of stocks.
