“…Researchers have also proposed strategies and developed models to integrate the production and maintenance planning decisions both at the tactical as well as at the operational levels. Various mathematical models focusing on coordinating production and maintenance plans are proposed in (Lin et al, 1992;Gurevich et al, 1996;Agogino et al, 1997;Ben-Daya and Rahim, 2000;El-Amin et al, 2000;Kiyoshi et al, 2002;Chattopadhyay, 2004;Martorell et al, 2005;Aghezzaf et al, 2007;Dahal and Chakpitak, 2007;El-Ferik, 2008;Fitouhi and Nourelfath, 2012;Wang, 2013). A wide variety of solution techniques and algorithms including the whole spectrum of heuristic techniques, dynamic programming, tabusearch multi-objective optimization, expert systems and many other hybrid techniques are also proposed, see for example (Lin et al, 1992;Gurevich et al, 1996;Agogino et al, 1997;Ben-Daya and Rahim, 2000;Kiyoshi et al, 2002;Chattopadhyay, 2004;Martorell et al, 2005;Dahal and Chakpitak, 2007).…”
