Abstract
Generalized optimization in engineering design is a synthesized problem. In this paper, some approach of authorized optimization in engineering design was reviewed. In chapter 2, some outlines in optimization were introduced. In chapter 3, an integrated system of design and production for metal sheet forming in virtual manufacturing was introduced as a case study of integrated optimization problem. In the system, the designer is able to evaluate the design process by a parameterized evaluation function and to examine the production results based on these design strategies in virtual space by means of CAD/CAE. In the paper, it is pointed out that the gap between simulation and experiments or real production must be taken into account whenever these kinds of product innovation enable us to obtain a quick response and result for the candidate design strategies in computer simulation. In chapter 4, some method of Quality Engineering was introduced.
