Life Cycle Maintenance Planning System in consideration of operation and maintenance integration
In this paper, we propose a maintenance planning method that takes into account the interrelation between maintenance and operations. In the proposed system, the maintenance plan is evaluated in terms of losses related to operations as well as maintenance. Operational losses include production losses due to both failure and maintenance operations. Maintenance losses include inspection costs, repair costs, and other losses such as those incurred due to operator injury. In addition, the system evaluates the risk of fatal failure. We have developed a prototype system that evaluates these losses using Monte Carlo simulation. The effectiveness of the system is demonstrated by applying the prototype to a heating furnace used in the direct desulfurization facility of an oil refinery plant.
