The purposes of this research are to make a generalized business process model of production scheduling work and to build a systematization reference model based on it. To make such a business process clear, various kinds of production work are analyzed and a generalized business process model is created. According to it, specifications for implementation modules and interfaces are designed and a systematization reference model combining these is proposed. In this research, the following two items are achieved. 1) A systematization reference model is proposed that overcomes several problems while scheduling systems are implemented. 2) A novel concept of spiral evolutional systematization which synchronizes system development with an environment changed by kaizen of production process is proposed. A systemization reference model for small and medium-sized enterprises based on this concept is proposed and a production scheduling system based on the model is developed and evaluated.
