ICARUS; redundant system unavailability model. [IBM370,303x; FORTRAN IV]
ICARUS calculates the unavailability characteristics of a periodically tested standby system with m-out-of-n redundancy (1.LE.m.LE.n.LE.4). The main functions of the program are to calculate the average unavailability, the optimum test interval, and fractional unavailabilities due to testing, repair, and random failures for three different testing strategies. The program will also calculate the average unavailability as a function of the test interval at each point in the range 0.2T(optimum) to 1.8T(optimum) at intervals of 0.2T(optimum). ICARUS can be used to evaluate sensitivities to different failure modes and data, as well as current testing or repair strategies, to determine if changes to these strategies will optimize the system availability.IBM370,303x; FORTRAN IV; OS/370; 60K bytes of memory are required for execution of the program.
