The generation of Pareto optimal solutions for complex systems with multiple conflicting objectives can be easier if the problem can be decomposed and solved as a set of smaller coordinated subproblems. In this paper, a new decomposition-coordination method is proposed, where the global problem...

A fully automatized in …-house optimization environment was used to solve the problem, including mesh generation and CFD (computational fluid dynamics …) simulations. The optimization was performed in parallel on a Linux cluster with a very good speed-up. …

This research proposes primitive cognitive network process (P-CNP), which comprises five decision processes, as an alternative of analytic hierarchy process (AHP). Two published cases using AHP are revised by P-CNP, and the validity and applicability of P-CNP are demonstrated. The comparison...

We study a multi-objective shortest path problem. We formulate a multi-objective Markov decision process model for the problem and solve it by the policy improvement procedure. We first show by counter-examples the differences between the multi-objective shortest path problem and the...

One important issue of component-based software development is the minimization of the development cost and the maximization of the system reliability while satisfying functional requirements. There are numerous publications on this issue based on metaheuristic techniques, but there are two...
