Abstract
After the Great East Japan Earthquake, industrial companies that store a certain amount of stocks, i.e., their finished products and unfinished products, are increasing. It is because they want to continue their business and to fulfill responsibility to supply the products to the market. Based on above-mentioned circumstances, practical method and criteria for estimating suitable amount of stocks are needed. This paper discusses evaluation method of recovery process from earthquake damage for manufacturing line consists of plural manufacturing apparatuses (components). And its points are; considering the finite amount stocks that are stored between each manufacturing process, and taking impacts of the damage correlation between components into account. In addition, using the proposed method, recovery curves for an example of virtual manufacturing line including the stocks are estimated, and the damage correlation influence is clarified through the difference among the curves shape.
