N2 - There are working, fail-safe and fail-dangerous states in safety-critical manufacture systems. This paper presents three typical safety-critical manufacture system architecture models: series, parallel and series-parallel system, whose components lifetime distributions are general forms. Also the reliability related indices, such as the probabilities that the system in these states and the mean times for the system fail-safe and fail-dangerous, are derived respectively. And the relationships among the obtained indices of the three system architecture models are analyzed. Finally some numerical examples are employed to elaborate the results obtained in this paper. The derived indices formulas are new results and without component lifetime distribution assumptions, which have significant meaning for evaluating the manufacture system reliability and improving the manufacture system safety design.
