Optimal mission abort policy for the heterogeneous two-component system with constraints on simultaneous components' rescue

At many instances, mission abort in systems performing important tasks is followed by a rescue procedure that is mostly aimed at survival of costly systems. Existing mission aborting models assume that when more than one component is involved in accomplishing a mission, the rescue procedures for individual components are performed independently. However, systems often have no sufficient resources to perform the rescue procedures for several/all components simultaneously. Then the mission abort for some components can be delayed or cancelled. This paper considers the two-component system in which simultaneous rescue of both components is prohibited. It suggests algorithm for evaluating the expected mission losses for this setting. In addition, it formulates and solves the mission abort policy optimization problem and presents practical examples that show that the operational dependence between components effects the mission success metrics and the corresponding mission abort policy.
