The quality management of the imperfect production process under two monitoring policies

Develops a framework which provides a step towards better planning of production, scheming inspection and preventive maintenance. Studies the effects of an imperfect production process on the optimal production cycle time. The system is assumed to deteriorate during the production process and produce some proportion of defective items. Extends to the cases where the proportion of defective items and the cost of process restoration are not constant. Provides a comparative study of two monitoring policies where the preventive maintenance setting is used and not used in the deteriorating production process. These models are directly relevant to the management of the quality and reliability of the production process. When scheming inspection is adopted, it is shown that the optimal inspection intervals are equally spaced in the imperfect production process under the different policies, respectively. Provides a numerical example to illustrate the derivation of the optimal production cycle time in the models.
