Quality management of concurrent engineering project based on rework;

In this model,activity relationship DSM was employed to describe the sequential,parallel,overlapping and time-window constraint-dependent relationships among activities,an activity probability DSM was used to describe rework and iteration during activity execution due to uncertain factors,and the activity learning ability was also taken into consideration.

With advanced MCM-D technology, MCM rework process and cooling technology, the mean time between failures of Z900MCM can reache forty years.

the economical selection of the quality level of a production process with a given sampling and reworking plan is discussed.
