摘要

In this paper, a process is considered which has multiple dependent quality characteristics. This process is subject to deterioration with time. The deterioration occurs due to assignable causes at a random point in time. The occurrence time of the assignable causes are assumed to follow two types of distribution functions: exponential and uniform. Earlier research did not consider the dependency of multiple quality characteristics in deteriorating states. A mathematical model is developed for this problem to minimise the cost of quality, process adjustments, maintenance and defects. A generalised reduced gradient search algorithm is used to find the parameters to minimise total cost per unit time for a number of numerical examples. Sensitivity analysis of the given model is also presented.
