We address the design for reliability of complex systems, such as Flexible Manufacturing Systems (FMS), through mathematical modelling of the machine failure, spares inventory, and repair processes. The unique model allows separation of systems by Machine Part Type (MPT); thus, we can model an extremely complicated FMS through many simpler models. Our measure of system effectiveness is based on a performability measure that credits partial availability by the performance of the system in that state. By comparing performability measures, designers and managers can affect the system reliability. Examples demonstrate how to use these developments.
