Assessment of Dynamic Maintenance Management
Abstract
Todayâ s technological systems are expected to perform at very high standards throughout
their operational phase. The cost associated with unavailability of these systems is very
high and especially with the defense systems or medical equipments which can directly
affect human lives. The maintenance system plays an important role in achieving higher
performance targets. In order to manage maintenance activities in more informed and
rational manner, it is very important to understand the inherently complex and dynamic
structure of the system. Traditionally maintenance policies are derived from reliability
characteristics of individual components or sub-systems. This research makes an attempt
to understand the system from the forest level and suggest better maintenance policies for
achieving higher availability and lower system degradation. The leverage is gained from
System Dynamics frameworkâ s ability to model complex systems and capture various
feedback loops. The simulation results reveal that with the limited preventive
maintenance capacity and within the given assumptions of the model, there exists and
optimal preventive maintenance interval which is not the minimum. The simulation
results also reflect that frequent preventive maintenance is required at higher load factors.
