A software cost model with maintenance and risk costs for safety-critical systems
【Abstract】 According to the consequences of software failures, software faults remaining in safety-critical systems can be classified into two sets: common faults and fatal faults. Common faults cause slight loss when they are activated. A fatal fault can lead to significant loss, and even damage the safety-critical system entirely when it is activated. A software reliability growth model for safety-critical systems is developed based on G-O model. And a software cost model is proposed too. The cost model considers maintenance and risk costs due to software failures. The optimal release policies are discussed to minimize the total software cost. A numerical example is provided to illustrate how to use the results we obtained.
