An approach to modelling dependencies linking engineering processes

A multi perspective modelling method is described that was developed and used to support an international consortium of businesses concerned with realizing automobile engine production on a global scale. The modelling method provides a capability of documenting, communicating and analysing various dependent aspects of multiple threads of engineering activities. Commercially available and specially developed computer modelling tools have been deployed to operationalize the method, and thereby to facilitate the design of dependent activity flows, the resourcing of activity flows by suitable human and technical systems and the control and management of workflows. The paper outlines requirements of the method, with reference to properties of engineering processes that needed to be modelled. A prime focus of attention was on engineering a new generation of component-based manufacturing lines suitable for the 'mass customization' of automotive engine products in production plants around the globe. Key features of the modelling framework are described, as are the stages of modelling and the associated use of proprietary modelling tools. Also provided are examples of models generated when using the method and tools.
