论文摘要
我们考虑了一种场景，灾难发生后多个基础设施组件损坏了，如果维修机构不被维修机构对目标，则每个组件的健康价值将继续恶化，直到它不可逆地失败为止。有多个机构试图修复组件，并且有一个机构的任务是将组件分配给给定预算之内的机构，以便最大化该机构完全维修的组件总数。当维修速率大于恶化速率时，我们表征了分配和维修测序的最佳策略。对于劣化速率大于或等于维修率的情况，该率在整个组件中是均匀的，并且实体进行维修的成本相等，我们表征了分配和维修顺序的策略，该策略是由最佳政策永久维修至少一半的组件数量。
We consider a scenario where multiple infrastructure components have been damaged after a disaster and the health value of each component continues to deteriorate if it is not being targeted by a repair agency, until it fails irreversibly. There are multiple agencies that seek to repair the components and there is an authority whose task is to allocate the components to the agencies within a given budget, so that the total number of components that are fully repaired by the agencies is maximized. We characterize the optimal policy for allocation and repair sequencing when the repair rates are sufficiently larger than the deterioration rates. For the case when the deterioration rates are larger than or equal to the repair rates, the rates are homogeneous across the components, and the costs charged by the entities for repair are equal, we characterize a policy for allocation and repair sequencing that permanently repairs at least half the number of components as that by an optimal policy.
