The set-based multi-objective satisfactory design for the initial design with uncertainties in collaborative engineering

Abstract

The advancement in computer networks and information technologies has been rapidly changing the manufacturing environment from the environment in industrial age to it in information era. The engineering philosophy has been shifted from concurrent engineering to collaborative engineering among the respective areas of expertise in the design space. Handling the uncertainties in the initial design has a great importance especially for the collaborative engineering. Due to the complexity of today's products and the incorporated overlapping activities between the lifecycle functions, the multi-objective optimized design is necessary. We have proposed a preference set-based design method that enables the flexible and robust design under various sources of uncertainties while capturing designer's preference. This paper discusses the availability of our proposal for obtaining the multi-objective satisfactory solution in the collaborative engineering by applying to an automotive front-side frame and a material design problem of multilayer porous absorber and insulator. © Springer-Verlag London Limited 2009.
