Communication And Uncertainty In Concurrent Engineering, Christoph. H. Loch, Christian Terwiesch Aug 1998

Communication And Uncertainty In Concurrent Engineering, Christoph. H. Loch, Christian Terwiesch

Operations, Information and Decisions Papers

We present an analytical model of concurrent engineering, where an upstream and a down-stream task are overlapped to minimize time-to-market. The gain from overlapping activities must be weighed against the delay from rework that results from proceeding in parallel based on preliminary information. Communication reduces the negative effect of rework at the expense of communication time. We derive the optimal levels of concurrency combined with communication, and we analyze how these two decisions interact in the presence of uncertainty and dependence. Uncertainty is modeled via the average rate of engineering changes, and its reduction via the change of the modification ...
