Provides a self-contained exposition to the subject of design optimization Facilitates the use of optimization techniques for different problems Basic concepts of optimality conditions and numerical methods are described with simple and practical examples Emphasis is given on producing economical design using optimization software As reliable and design softwares are easily available, now is the time to concentrate on producing not only safe designs but also to produce economical designs. Standard softwares are available. But to use them confidently design engineers should have basic knowledge of optimization like mathematical formulation and suitability and limitation of the software. Hence nowadays design engineers must undergo a basic course in optimization. With this aim the author has written the book and hopes that students and faculty will accept it as useful textbook in engineering design.
