Abstract : Two models are developed for calculating the availability of the Harpoon missile airborne command and launch system (HACLS). The first model is a semi-Markov process. Its assumptions are validated using the subsequently developed computer simulation model. Both models are exercised with parametric variations, the critical parameters being mean time to failure, mean time to repair, and severity of the operating environment. Less critical parameters are maintenance efficiency and, for the simulation only, maintenance time to repair probability distribution. A major discovery in this paper is that the standard definition of availability does not prove to be adequate when used to determine system availability in a complex framework of operations.
