...Taylan G. Topcu; Suparna Mukherjee; Anthony Hennig; Zoe Szajnfarber Decomposition is a dominant design strategy because it enables complex problems to be broken up into loosely coupled modules that are easier to manage and can be designed in parallel. However, contrary to widely held expectations...

... L x , L y , and L z can be regarded as random variables following normal distributions. The distribution parameters including mean and standard deviation are given in Table 12 . Based on the vine copula function, this paper proposes a numerical decomposition method to calculate...

... a decomposition method that exploits parallel computing, including the determination of an optimal number of subsystems by using a multi-objective optimization formulation and a messy genetic algorithm (GA) modified to handle discrete design variables. In the suggested method, an MDA process is decomposed...

...Noemi Chiriac; Katja Hölttä-Otto; Dusan Lysy; Eun Suk Suh All complex system development projects involve analysis of the system architecture. Thus far it has been assumed that there is some correct system decomposition that can be used in the architectural analysis without consideration...

...Aida Khajavirad; Jeremy J. Michalek We propose a deterministic approach for global optimization of nonconvex quasiseparable problems encountered frequently in engineering systems design. Our branch and bound-based optimization algorithm applies Lagrangian decomposition to (1) generate tight lower...

...Masataka Yoshimura; Yu Yoshimura; Kazuhiro Izui; Shinji Nishiwaki This paper proposes a system optimization method for product designs incorporating discrete design variables, in which hierarchical product optimization methodologies are constructed based on decomposition of characteristics...

...Li Chen; Ashish Macwan; Simon Li This paper presents a pattern-based decomposition methodology for rapid redesign to support design customization in agile manufacturing of evolutionary products. The methodology has three functional phases. The first phase, called design dependency analysis...

... matrices. The matrix is then decomposed into a central compliance matrix and an adjoint transformation, leading to the decomposition of the legs’ parameter effect from the platform assembly influence. The analysis presents the necessary and sufficient condition for the existence of the twist deflection...

...Masataka Yoshimura; Masahiko Taniguchi; Kazuhiro Izui; Shinji Nishiwaki This paper proposes a machine product design optimization method based on the decomposition of performance characteristics, or alternatively, extraction of simpler characteristics, that is especially responsive to the detailed...
