Abstract Proper maintenance management policies can reduce overall medical devices operation cost, decrease degradation and increase availability. This paper presents a system dynamics simulation model that was designed to evaluate the initiative contributions of preventive maintenance and corrective maintenance towards improving the overall performance of medical devices in developing countries. The study proposes and formulates better maintenance strategies to achieve higher operational availability and lower deterioration for medical devices. Simulation results show that maintenance management could reduce corrective maintenance levels by increasing preventive maintenance level, therefore increasing medical devices availability and reducing maintenance cost. The results also show that the changing the workload and the frequency of preventive maintenance have an effect upon the performance of hemodialysis machines. The simulation results reveal that the workload and operational cycle time are inversely proportional with the hemodialysis availability and maintenance cost effectiveness and directly proportional with the hemodialysis degradation, breakdowns and total maintenance cost. The statistical analysis of the simulation results demonstrates that there is a significant improvement in the performance of medical devices with reduction in workloads and operational cycle times. This study investigates the applicability of maintenance policies in the hospitals of developing countries and how they can generate significant operational benefits. Keywords: Maintenance Policies, Medical Devices, Statistical Analysis, System Dynamics.
