Multidisciplinary Design Optimization Supported by Knowledge Based Engineering

2Modern Design and Optimization

2.1 Background to Chapter

This chapter sets the scene for the introduction of multidisciplinary design and optimization (MDO) methods and techniques in the design of modern products. It starts by exploring the nature of modern design then moves on to link this to the need for the application of optimizing methods which then leads on to the role played by MDO. We should emphasize that while, in the course of this book, we introduce and develop methods and models for MDO systems supporting the design of major engineering products, we are not advocating a rigid adherence to any of the methods and processes discussed. The key consideration in the selection or development of an appropriate design methodology is the nature of the design being addressed; it is always a question of “horses for courses.” It may be that a given design optimization problem is ideally suited to being solved by one of the methods to be presented in later chapters; but it may not be. In this latter situation, the reader may adopt a “pick and mix” approach taking components from several methods to generate an appropriate MDO system for the problem being confronted. Going farther down this pathway, the reader may decide to undertake a “pick and add” approach where some of the ideas presented are taken and added to by the introduction of new ideas specifically developed for the problem being addressed. This is an exciting path to go down as new ideas are required; however, if speed ...
