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.
