摘要资本资产，如风力涡轮机和船舶，需要在其漫长的生命周期内进行维护。资产通常需要离线执行维护，这种停机可以是计划的，也可以是非计划的。由于资产中的不同组件有不同的维护策略，因此制定维护计划以协调所有组件的维护策略非常关键，以最大限度地减少与维护和停机相关的成本。单一组件维护策略已经制定了几十年，但此类策略通常不允许在资产内的不同组件之间进行协调。研究了部件之间可以协调计划停机的定期维修策略和状态维修策略。在这两种策略中，我们都假设在非计划停机时，会执行最小限度的维修，以使非计划停机时间尽可能短。这两种策略都可以使用更新理论进行准确的评估，并且我们展示了如何将这些策略作为构建块来设计和优化多组件资产的维护计划。
ABSTRACT Capital assets, such as wind turbines and ships, require maintenance throughout their long lifetimes. Assets usually need to go offline to perform maintenance, and such downs can be either scheduled or unscheduled. Since different components in an asset have different maintenance policies, it is key to have a maintenance program in place that coordinates the maintenance policies of all components, to minimize costs associated with maintenance and downtime. Single-component maintenance policies have been developed for decades, but such policies do not usually allow coordination between different components within an asset. We study a periodic maintenance policy and a condition-based maintenance policy in which the scheduled downs can be coordinated between components. In both policies, we assume that at unscheduled downs, a minimal repair is performed to keep the unscheduled downtime as short as possible. Both policies can be evaluated exactly using renewal theory, and we show how these policies can be used as building blocks to design and optimize maintenance programs for multi-component assets.
