Abstract:
Companies are generally aiming to gain more reliable production systems with higher availability performance and having good maintenance policy which playes a major role in achieving systems' operational effectiveness at minimum cost .All types of systems such as geographically distributed systems (e.g. ATMs, electric vehicle charging stations, off-shore wind farms, and so on) have prescribed maintenance schedules set forth by the manufacturer that aims to reduce the risk of assets failure. In this study we integrated the VRP problem with maintenance activity to solve this problem. In addition to previous models, we have prioritized assets and considered soft and hard time windows for each asset considering its type and importance. Finally, the model, trying to minimize cost and unavailability, is solved by Epsilon-constrain method and the results are discussed
