Design Theory and Methods using CAD/CAE

5.4. Decision-Based Design

In general, engineering design is viewed as a problem-solving process. Such as in this chapter, a design problem is formulated mathematically as optimization problem and solved by meeting functional requirements subject to constraints at minimum objectives.

As mentioned in Chapter 2, engineering design is increasingly recognized as a decision-making process. From a product development perspective, design involves a series of decisions—some of which may be made sequentially and others that must be made concurrently. The term decision-based design (DBD) was introduced in 1990s. A formal definition introduced in (Hazelrigg 1998) states that decision-based design is a normative approach that prescribes a methodology to make ...
