The integration among the organizational functions managing assets along its lifecycle is a crucial aspect for production companies to implement Asset Management. In this paper, an iterative four-step methodology is presented to support the joint maintenance and production planning considering the system configuration optimization as well. The objective is to overcome the limitations of most of the approaches that can be found in the literature regarding joint optimization models, by integrating it with a system-oriented and reliability-based approach. Reliability, Maintainability and Availability analysis at system level is used to support the traditional joint optimization models. The methodology is applied in an industrial case in the mining sector.
