In recent years, maintenance, especially its preventive type, has been seen as an effective and considerable factor in improving the functions of machines. Maintenance plays a vital role in organizations by keeping and increasing the reliability, accessibility, the quality of products, risk mitigation, return improvement, and safety. An effective maintenance programme can be realized by implementing a proper maintenance strategy. Therefore, maintenance and its strategies have a special status in industries. However, selecting a proper maintenance strategy has always been a complex process because maintenance is a nonrepetitive task. Likewise, the lack of failure records and constant changes in the conditions of machines makes it further complicated. Hence, the decision-making also depends on experts' opinions and because some kind of risk and uncertainty are always there in experts evaluations, the reliability of evaluations is questionable. The present study was aimed to develop a risk-based model grounded on the analytical hierarchical process, namely, RAHP, to meet this need of maintenance. A case study from a steel rolling company was considered to evaluate the effectiveness of this model.

使用RAHP进行具有风险评估的维护策略选择

近年来，维护，尤其是其预防性维护，已被视为改善机器功能的有效且重要的因素。维护在组织中起着至关重要的作用，它可以保持并提高可靠性，可访问性，产品质量，降低风险，提高退货率和安全性。通过实施适当的维护策略，可以实现有效的维护程序。因此，维护及其策略在行业中具有特殊的地位。但是，选择适当的维护策略一直是一个复杂的过程，因为维护是一项非重复性的任务。同样，缺乏故障记录和机器状况的不断变化也使其变得更加复杂。因此，决策还取决于专家的 意见以及专家评估中总是存在某种风险和不确定性，因此评估的可靠性值得怀疑。本研究的目的是建立一个基于风险的模型，该模型基于分析层次过程，即RAHP，以满足维护的需求。考虑了一家轧钢公司的案例研究，以评估该模型的有效性。
