Equilibrium stability in decentralized design systems Authors Chanron, V., Singh T., & Lewis, K. Source International Journal of Systems Science, 36(10), 651-662, 2005. Abstract
The focus of this paper is on complex systems, and it presents a theoretical study of the design
of complex engineering systems. More particularly, this paper studies the stability of equilibria
in decentralized design environments. Indeed, the decentralization of decisions is often
recommended in the design of complex systems, and the decomposition and coordination of
decisions are a great challenge. The mechanisms behind this network of decentralized design
decisions create difficult management and coordination issues. However, developing efficient
design processes is paramount, especially with market pressures and customer expectations.
Standard techniques to modelling and solving decentralized design problems typically fail to
understand the underlying dynamics of the decentralized processes and therefore result in suboptimal
solutions. This paper aims to model and understand the mechanisms and dynamics
behind a decentralized set of decisions within a complex design process. Complex systems
that are multidisciplinary and highly nonlinear in nature are the primary focus of this
paper. Therefore, techniques such as response surface approximations and Game Theory
are used to discuss and solve the issues related to multidisciplinary optimization. Nonlinear
control theory is used in this paper as a new approach to study the stability of equilibrium
points of the design space. Illustrations of the results are provided in the form of the study
of the decentralized design of a pressure vessel.
