The business processes of manufacturing enterprises have to be dynamic,especially when highly customised products are manufactured or different projects work simultaneously.Another trend in contemporary manufacturing is the necessity for co-operation between geographically dispersed teams.This book presents a new method for modelling business processes enabling co-ordination of dynamic workflows.First we focus on Business Process Modelling (BPM) techniques and outline the limitations of the existing methodologies. Similarly,an overview of Enterprise Collaborative Portals (ECP) is conducted and a method for collaborative authoring of dynamic workflows is discussed.Next,the book introduces the concept of business process models with feedback based on the Product/process (P/p) methodology.An extension to this methodology, validated through a case study,is developed to overcome some of its limitations.Its performance is analysed and compared with that of UML and its advantages are highlighted.The book also proposes a benchmarking method for business processes. Finally,a method for modelling business processes enabling co-ordination of dynamic workflows is presented.
