A process for reliability-related quality programming is developed to fill existing gaps in software design and development so that a quality programming plan can be achieved. This study investigates the tradeoffs among system reliability improvement, resource consumption, and other relevant constraints through the management phase. A software reliability-to-cost relation is developed both from a software reliability-related cost model and from software redundancy models with common-cause failures. A generic N-component redundancy model is also developed. The software reliability optimization problem can be formulated into a mixed-integer programming problem. © 1990 IEEE
