Abstract
In a batch process new products are manufactured by changing the recipes. The recipe design projects of multiple products are executed in parallel or in sequence, and the recipe design process of each product has many recycle steps. Thus, the management of recipe design project has been executed manually. In this study, from the viewpoint that the systematization of recipe design process is the key factor for agile production, the recipe design process is modeled. In the developed model, an index called "certainty" is introduced to express the degree of reliability of each recipe design step. By using the developed model the simulation based analysis method is proposed to improve the organizational potential.
