Planning and Control of Concurrent Engineering Activities Under Uncertainty

The engineering process provides technical documents. It can be modeled by extending the Walrasian model. Concurrent engineering involves shortening of lead time and life cycle engineering. Shortening of lead time can be done by choosing an uncertainty level and using an iterative algorithm to determine optimal concurrency. Cost uncertainty can be included by adding contingency. Cost and time uncertainty in a project can be catered for by providing risk buffers.
