Chapter 6 Development Cost Optimization
In this chapter, we solve the problem of development cost optimization for parallel applications of embedded systems under ensuring the functional safety requirements based on the ASIL decomposition defined in ISO 26262. We propose two techniques to address the problem. The first technique presents two heuristic algorithms, reliability calculation of scheme(RCS) and minimum development cost with reliability requirement(MDCRR). We first use RCS to calculate the reliability value of each ASIL decomposition scheme; then the MDCRR is used to select the scheme with the minimum development cost without violating reliability constraint. The second technique presents a two-stage ...
