Process data warehouse models for cooperative engineering processes

The design and development processes of complex technical systems are important to the competitiveness of enterprises. These processes are characterised by high creativity and strong non-deterministic dynamics spanning different disciplines, relying on cooperation of different organisations. To successfully support these cooperative activities, methods of experience management are needed. This paper describes the capturing of process and product traces in an ontology-based Process Data Warehouse (PDW). These traces can be processed and reused in further development and cooperation cycles. The concept of the PDW has been evaluated in an engineering case study in the domains of chemical and plastics engineering.
