ABSTRACT

Maintenance and production are closely related in di®erent ways. is relationship makes production planning and maintenance planning the most important and demanding areas in the process of decisionmaking by industrial managers. Hence, they have been the focus of attention in the manufacturing industry while a lot of research has also been devoted to them in the area of operations research. Although the two activities are interdependent, they have most often been performed independently. Integration of production planning and maintenance planning into one single problem is a complex and
