Optimal Servicing Strategy Involving Imperfect Repair and Preventive Maintenance for Products Sold with One-Dimensional Warranties

Mustofa, H. Husniah, B. P. Iskandar

Abstract


A manufacturer tends to offer a longer warranty period ranging from 3 to 7 years in order to get its product more competitve in a market place. Offering a product with a longer warranty period would increase the warranty cost and this is of great interest to the manufaturer to reduce it. For a repairable product, an effective servicing strategy which combines minimal repair and imperfect repair can reduce the warranty cost significantly. But this servicing strategy confines the number of imperfect repairs, at most one, over the warranty period. For a longer warranty period, more imperfect repairs would be needed in order to reduce the number of failures over the warranty period. In this paper we study two new servicing strategies where performing of imperfect repairs is dependent on the age of failure under warranty. A numerical example is given to illustrate the optimal solution and compare results of the strategies developed with the similar servicing strategy studied previously.
