A Preventive Maintenance And Minimal Repair Costs Model With Interest Rate
- Share to:
Abstract
This paper deals with minimal repair and sequential imperfect preventive maintenance (imperfect PM) for a fishing vessel. Failure that occur at random times rectified by minimal repair, result minimal repair cost. We add the downtime cost to modify the cost model previously discussed by Jiang and Murthy (2008). That cost is intended as a cost of losses when the vessel is being repaired. Because of the time value of money, each cost should be subject to interest rate. The performance measure is the minimization of the expected total maintenance cost during a certain period. The decision variables are the number of imperfect PM and the level of preventive actions. We assume the distribution of first failure rate is Weibull and follows a nonhomogeneous Poisson process (NHPP). We give the comparison of maintenance costs between the cost resulting from our model and that from the previous model. The previous model is nested in our model and the result shows that in our model a higher interest rate will increase the maintenance cost.
