PROBLEM TO BE SOLVED: To determine such an order quantity that further increase of benefits can be expected under restrictions.SOLUTION: A data tabulation section 111 tabulates actual sales data from an external POS system. A demand prediction generation section 112 predicts a demand quantity from a period (k) to a period (k+H) after a read-ahead interval H. A prediction model generation section 113 generates a basic model for calculating the quantity of stock for each period. A restriction generation section 121 generates a restriction condition relating to the order of articles. A target function generation section 122 generates a target function for calculating a benefit during a designated term from the period (k) to the period (k+H). An optimal order quantity calculation section 130 calculates an optimal order quantity for increasing the benefit within the designated term within a range meeting the restriction condition. The optimal order quantity calculation section 130 calculates the range of a benefit estimated on the basis of the calculated order quantity for each period. An output section 160 outputs a GUI image to a monitor 20, the GUI image representing a total order quantity and the range of benefit prediction in a tabular format. 【課題】制約の下で利益がより高くなることが見込まれる発注量を決定すること。【解決手段】データ集計部１１１は、外部のＰＯＳシステムからの実際の売上データを集計する。需要予測生成部１１２は、ｋ期から先読み区間Ｈ先のｋ＋Ｈ期までの需要量を予測する。予測モデル生成部１１３は、期毎に在庫数を算出するための基本モデルを生成する。制約生成部１２１は、商品の発注に関する制約条件を生成する。目的関数生成部１２２は、指定期間ｋ期〜ｋ＋Ｈ期内の利益を算出するための目的関数を生成する。最適発注量計算部１３０は、制約条件を満たす範囲で指定期間内の利益を高める最適発注量を計算する。最適発注量計算部１３０は、計算された各期の発注量に基づいて想定される利益の範囲を算出する。出力部１６０は、総発注量と利益予測の範囲とを表形式で表したＧＵＩイメージを、モニタ２０に出力する。【選択図】図１
