Multi-objective formulations are realistic models for many complex engineering optimization problems. In many real-life problems, objectives under consideration conflict with each other, and optimizing a particular solution with respect to a single objective can result in unacceptable results with respect to the other objectives. A reasonable solution to a… (More)

& Conclusions-A problem specific genetic algorithm (GA) is developed and demonstrated to analyze series-parallel systems and to determine the optimal design configuration when there are multiple component choices available for each of several k-out-of-n:G subsystems. The problem is to select components and levels of redundancy to optimize some objective… (More)

This paper presents an approximation methodology for estimating the reliability of a multi-state network. The problem under consideration is known as the multi-state two-terminal reliability (M2TR) computation. Approaches for obtaining this measure rely on the computation of multi-state minimal cut vectors (MMCV) and the application of inclusion/exclusion… (More)

abstract – A new heuristic is proposed and tested for system reliability optimization. The multiple weighted objective heuristic is based on a transformation of the problem into a multiple objective problem, and then ultimately, transformation into a different single objective problem. The multiple objectives are to simultaneously maximize the reliability… (More)
