Models for supply chain reengineering

The goal of this paper is to provide a first step in the development of a c oherent 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 ar e presented: the event process chain (EPC) method: the activity chain model (ACM) method; and the GRAI grid method (adjusted for supply chains). EPC m odelling focuses on time relationships between primary process/functions, a nd is customer oriented. ACM modelling focuses on functions/processes and i nformation flows. GRAI focuses on decision structures and information flows . The three methods are described, and an application of the methods to a c ase study company is presented. This paper concludes with a comparison of t he methods and a discussion of their applicability.
