STOCK LAYOUT OPTIMIZATION SYSTEM AND STOCK LAYOUT OPTIMIZATION METHOD

To provide a stock layout optimization system and a stock layout optimization method capable of minimizing the frequency of replenishment of commodities to a picking area in a physical distribution warehouse, thereby improving efficiency of the operation.SOLUTION: A stock layout optimization system 100 includes: a storage unit 101 which stores information on various constraint conditions pertaining to a picking area in a physical distribution warehouse; and a computing unit 104 which calculates values of decision variables that maximizes the number of commodities to be stored by a mathematical optimization solver under the above constraint conditions, using the number of commodities stored in a storage shelf in the picking area as an objective function, and layout position of the storage shelf where a group of commodities is stored, and the layout position in the storage shelf, the number of stacks of commodities constituting the group, and the numbers of commodities arranged in lateral direction and depth direction as the decision variables.SELECTED DRAWING: Figure 4 【課題】物流倉庫におけるピッキングエリアへの商品補充回数を最小化し、当該業務の効率化を可能とする在庫配置最適化システム及び在庫配置最適化方法を提供する。【解決手段】在庫配置最適化システム１００において、物流倉庫におけるピッキングエリアに関する各種制約条件の各情報を格納した記憶部１０１と、ピッキングエリアの収納棚における商品の収納数を目的関数、商品の集合体の収納先となる収納棚及び当該収納棚での配置位置と、集合体を構成する商品の積み上げ段数と横幅方向及び奥行き方向での配置数のそれぞれを決定変数とし、上述の制約条件の下、数理最適化ソルバーによって商品の収納数を最大化する決定変数の各値を演算する演算部１０４と、を備える。【選択図】図４
