To satisfy their main goal, namely providing quality water to consumers, distribution networks (WDNs) need be suitably monitored. Only well designed and reliable monitoring data enables WDN managers make sound decisions on systems. In this belief, utilities worldwide have invested in acquisition However, good needs optimal sensor placement presents a multi-objective problem where cost are confl...

time, cost and quality are considered as the main components in managing each project. previous researches have mainly focused on the time-cost trade-off problems. recently quality is considered as the most important factor in project�s success, which is influenced by time acceleration that is the less time is spent the more success is gained. in time-cost-quality trade-off problems, each act...

Abstract A simple multi-physical system for the potential flow of a fluid through shroud, in which mechanical component, like turbine vane, is placed, modeled mathematically. We then consider multi-criteria shape optimization problem, where component allowed to vary under certain set second-order Hölder continuous differentiable transformations baseline with boundary same continuity class. As o...

rapid technological and economic growth over the last several decades has changed human lives and made modern society face complex decision making problems. these kinds of problems are characterized by incommensurate and conflicting criteria or objectives such as cost, reliability, performance, safety and productivity. multi criteria decision making is an approach that can be used to deal compl...

Through quantitative evaluation of the data and information compiled in the literature review and survey, an explicitly defined list of alternatives and decision criteria to evaluate rehabilitation alternatives was developed for culverts 122 centimeter (48 inch) in diameter or smaller. Relative weights of each criterion were assigned in comparison to the defined alternatives, thereby allowing a...
