Benefits of process modeling within the engineering of automated facilities

Engineering of automated facilities is today planned with typical project management methods. The overall engineering process is captured in models like gantt charts summing up time estimations for the completion of subsections. To organize the complexity caused by the different involved disciplines organization charts are defined to handle the organizational complexity. Overall plans handling the technical complexity and to uncover the technical expertise and experience of the involved engineers do normally not exist. Despite in research the well known approaches of process modeling, often used for business processes and software implementation, are used to uncover this knowledge. The intend of this paper is to give an overview and a description of the achievable benefit of engineering process modeling on different levels of abstraction. For this target existing research papers and activities will be presented. Existing gaps to bring this approaches into practical use are shown.
