The goal of this paper is to provide a first step in the development of a coherent set of modelling methods for supply chain reengineering. This paper shows that different fields of attention in supply chain management should be approached with different modelling methods. Three modelling methods are presented: the event process chain (EPC) method; the activity chain model (ACM) method; and the GRAI grid method (adjusted for supply chains). EPC modelling focuses on time relationships between primary processes/functions, and is customer oriented. ACM modelling focuses on functions/processes and information flows. GRAI focuses on decision structures and information flows. The three methods are described, and an application of the methods to a case study company is presented. This paper concludes with a comparison of the methods and a discussion of their applicability.
