One of the problems that System Engineers have to deal with whilst carrying out system design is to allocate requirements to the subsystems. An approach based on a stochastic model to perform requirements allocation to the subsystems of a Shipborne Weapon System (SWS) is outlined in this paper. The model allows computing the overall system performance, in terms of Probability of Escaping Hits ( PEH ). Computation of PEH is related to the predetermined set of multi‐threats scenarios (including the threat characteristics), the defended area and the ship vulnerability, but at the same time it is subject to functional, physical and performance assumptions of the subsystems as derived from trade‐off studies. On one hand, the model allows to check whether the overall system performance of a SWS configuration, not completely defined by the customer, is achieved and eventually, after the needed iterations, the parameters characterising each subsystem become requirements. On the other hand, if the subsystems characteristics are known, the model allows checking the overall system performance.
