To provide an inventory quantity transition simulation method that can predict the transition of the inventory quantity by product type in a practical calculation time without the necessity of determining the transportation rules for each situation in detail.SOLUTION: An inventory quantity transition simulation method according to the present invention is the inventory quantity transition simulation method for predicting a transition of an inventory quantity of intermediate products in a storage area provided for a production line and a transportation line, and includes; a step of inputting input information including information on the quantity of intermediate products and route information between storage places through which the intermediate products can pass; a step of creating a mathematical model including constraint expressions and evaluation functions based on the input information; and a step of outputting the transition of the inventory quantity of the intermediate product at the storage location based on the created mathematical model. Here the information on the quantity of intermediate products is treated as a continuous quantity based on the weight of intermediate products summarized for each product type.SELECTED DRAWING: Figure 2 【課題】大規模かつ複雑な物流に対しても、状況ごとの搬送ルール等を詳細に決める必要がなく、品種ごとの在庫量の推移を実用的な計算時間で予測可能な在庫量推移シミュレーション方法を提供する。【解決手段】本発明に係る在庫量推移シミュレーション方法は、製造ライン及び搬送ラインに対して設けられた置き場における中間製品の在庫量の推移を予測する在庫量推移シミュレーション方法であって、中間製品の量に関する情報と、中間製品が通過可能な置き場間の経路情報とを含む入力情報を入力するステップと、入力された入力情報に基づく制約式及び評価関数を含む数理モデルを作成するステップと、作成された数理モデルに基づいて、置き場における中間製品の在庫量の推移を出力するステップと、を含み、中間製品の量に関する情報は、品種ごとに集約した中間製品の重量に基づき連続量として扱われる。【選択図】図２
