The acronym R.A.M.S. (Reliability, Availability, Maintainability, Safety) concerns the application of important methodologies for designing and managing complex systems. The present work proposes some guide lines for a right analysis and consequently allocation of the Safety parameter. The identification and allocation of Safety requirements is the process that assigns these requirements to each part and subsystem, allowing the whole system to reach the Safety target pre-designed. The starting point is the analysis of the allocation techniques present in literature. Starting from the application fields, advantages and disadvantages of the above techniques, the work proposes a new methodology, called "Integrated Hazards Method". IHM method will be applied to the pre-design phase of complex systems, but also to following phases of development and management, systematically and economically. The mathematical formulation of the new method has been developed thanks to a case study, an unmanned aerospace system. By comparing the allocation results of the new technique with other techniques and with historical data of the system, we have appreciated its validity.
