Optimum Replacement Time for a Deteriorating System

The Preventive Replacement strategy for determining an optimal replacement time for an automobile system that deteriorates with time is proposed and investigated, while the part of the system is in the final stages of its life span. The failure time followed the weibull, distribution and hence, the optimum replacement time can be determined. This time minimizes total downtime and maximizes the proportion of time the parts of the system available.
