This paper reports on a maintenance and reliability simulation program recently put into operation at Douglas Aircraft Company, instigated by the NASA-Langley study for Manned Orbital Research Laboratory, (MORL). The program has some features which should be of interest to the aerospace industry in general, and in particular, those companies concerned with space travel and space station inflight maintenance problems.
The program has been used to yield valuable information about queue lengths, maintenance time, trade-off analysis of reliability versus spare weight, crew size, and mission length.
The paper discusses the Monte Carlo methods used, the program logic, and special features that distinguish this program.
