In every production system, malfunctioning or breakdown during run time can incur heavy loss to the organization, to overcome such a situation it is crucial to use maintenance actions which can be either corrective or preventive depending upon the condition of the system. Also, warranty policy is extensively used world-wide to increase customer confidence in the product and to uplift sales. On account of this, the present chapter presents a problem of a manufacturer dealing with an imperfect production system considering maintenance actions and warranty policy by trading off the rework cost, holding cost, warranty cost and corrective/preventive maintenance cost so as to minimize the manufacturer's total cost. Numerical analysis and sensitivity analysis is performed to showcase model features.

Literature Survey

Almost all the organization these days work upon quality control as it is viewed as a progressive tool to improve the overall profit of any organization. In the highly aggressive markets the prime motto is to keep a check on the quality control so as to cater the customers with good quality items. Despite all the quality checks and adopting latest technologies the imperfection in the production process cannot be eradicated completely. It is therefore not genuine to assume that all units are of good quality or the manufacturing system is perfect because as a matter of fact the production process is prone to random errors that may lead to defectives. In light of this several researchers explored the area of imperfect quality. The pioneer work in this category was contributed by “Porteus (1986)” and “Rosenblatt and Lee (1986)” thereafter a number of researchers explored this area viz. “Kim and Hong (1999), Salameh and Jaber (2000), Chung and Hou (2003), Papachristos and Konstantaras (2006), Maddah and Jaber (2008), Jaggi et al. (2013), Aditi et al. (2016, 2017)” and many more.
