Abstract: For critical systems, such as satellites and aircraft, survivability can be extremely important as failures can result in irreversible economic loss and even casualties. A mission abort policy and the subsequent rescue procedure are effective tools for increasing the survivability of systems performing missions of fixed or variable duration. However, it comes at a price of decreasing the mission success probability. Therefore, a reasonable trade-off should be achieved. This problem has been studied in numerous publications, however, we are the first to discuss general multi-component coherent systems. Moreover, the new methodology based on signatures describing coherent systems is employed for description and defining a criterion of abort. Several optimization problems are formulated and discussed. The detailed numerical examples illustrate our findings and justify the developed innovative approach.
