Design Theory and Methods using CAD/CAE

5.6. Advanced Topics

Before closing out this chapter, we include two advanced topics that are relevant to design optimization. The first topic is reliability-based design optimization (RBDO), which incorporates variations in physical parameters and design variables into design optimization, leading to design with less probability of failure. Second, we introduce a case of design optimization that takes product cost, including manufacturing, as an objective function. This case represents a more realistic design optimization problem that leads to less expensive designs.

5.6.1. Reliability-Based Design Optimization

In Chapter 5 of Chang (2013a), we discussed reliability analysis. We introduced the concept of failure modes associated with certain critical ...
