Use of CIMOSA and systems thinking to document and inform the design and development of car engine production systems

General enterprise engineering requirements are reported that arose during the design and production engineering of a range of component-based car engines. This needed teams of engineers from a global consortium of companies to currently resource multiple threads of complex engineering processes over an approximate four year timeframe. This paper characterizes the enterprise engineering requirements observed and provides a rationale for specifying, developing and using a new approach to Multiple Process Modelling (MPM). MPM unifies and extends the use of a pre-existing selection of enterprise modelling concepts, architectures and tools. Particularly MPM unifies the use of CIMOSA, Systems Thinking methods and tools and a workflow tool. MPM is under ongoing development and testing in relation to the requirements outlined and related large scale systems engineering problems faced by the global consortium.
