The traditional production and maintenance planning models have been separately well documented, and much work was done to improve them. However, the integrated production and maintenance planning model emerged recently, and firms highly desire it due to its ability to ease the production process by including maintenance activities from the beginning of the planning horizon. In this paper, we present an integrated production and maintenance planning model. We compare the two block maintenance policies (as bad as old and as good as new). The results show that preventive maintenance is less frequent when using block-AGAN compared to ABAO, while the maintenance and production costs are higher.
