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 ...
