Maintenance Policy Optimization: Exploration Of Numerical Solutions For Complex Systems

Authors : Layouni Zoubir . Muhammad Suhail .

Abstract

This paper specifically concerns the design of an optimal maintenance policy in order to minimize costs; this also allows reducing the frequency of system failures and increasing its operating time during its mission. An algorithm has been developed and the generated results are encouraging, this conception aims to identify potential problems or defects as early as possible ensuring that corrective actions can be taken to prevent or mitigate any negative consequences. An optimal maintenance procedure should be based on a thorough understanding of the system or process being inspected, including its critical components and failure modes. It should also take into account factors such as the frequency and duration of inspections. Ultimately, an optimal solution provided should strike a balance between detecting potential problems early enough to take corrective action while avoiding unnecessary downtime or inspection costs. We propose mathematical models based on different aspects. The first one allows for an optimal solution without renewal. Then, we generalize the model and finally extend it by introducing the cost of renewal. To demonstrate the use of the models in practical applications, a numerical example is provided. Solutions to optimal system parameters are obtained and the response of the model to these parameters is examined.
