In order to define a SC (supply chain) simulation model efficiently, we propose a multi-functional modeling method, and develop a SC modeling and simulation tool, to which is installed the modeling method. In the proposed method, because a whole SC model is divided into 5 kinds of partial model that have different description each other from a view of a function in a SC, a whole SC model can be defined in a short time with a small number of components. In order to evaluate the efficiency to define/change a SC model and the accuracy of the simulation, the developed tool was applied to virtual and real SC. As a result, the time to model was 1/28 and the number of components was 1/8 compared to ones with an general simulation tool, and the error of the number of inventories output by the developed tool was 0.3 % and one of the deadline meet rate was 0.4 points compared with the real data.
