Optimal timing of reviews in concurrent design for manufacturability
Article Abstract:
Concurrent engineering involves the simultaneous rather than sequential performance of engineering activities. This strategy can shorten the period needed to develop a new product or redesign an old one. Unlike the traditional approach which requires the completion or near completion of the product design before it is passed on to the process design group, concurrent engineering calls for a performance of several progress reviews during the product design process. Conducting reviews frequently has two main benefits. Its parallel development benefit is that the availability of design information allows process engineers and product designers to work at the same time. The quality control benefit is that product redesign is minimized because flaws in the design are identified early. A simplistic model of concurrent engineering is analyzed.

The impact of inspection delay on process and inspection lot sizing
Article Abstract:
Research modeling the interaction of lot sizing and process quality indicate that lot sizes should be reduced in order to compensate for inferior quality in cases where effective inspection is impossible. The impact of inspection delay on the process quality of lot sizing was analyzed using the classical EOQ model of G. Hadley and T. Whitin (1963) and an inspection lot sizing problem. Only one inspection should be made if the delay is great, and the lot size should be as given by H. Lee, M. Rosenblatt and E. Porteus. The optimal production and inspection lot size for a wide spectrum of inspection delays is presented.
