The Shortest Path (SP) problem resembles a variety of real-world situations where one needs to find paths between origins and destinations. A generalization the SP is Dynamic (DSP) problem, which also models changes in graph at any time. When changes, DSP algorithms partially recompute while taking advantage previous computations. Although represents many real situations, it leaves out some fun...

implementation of the risk management concepts into construction practice may enhance the performance of project by taking appropriate response actions against identified risks. this research proposes a multi-criteria group decision making approach for the evaluation of different alternative response scenarios. to take into account the uncertainties inherent in evaluation process, fuzzy logic i...

In the present research, a multi-objective model is proposed, which considers equity among the citizens in addition to the cost criterion. Then, the model will be solved using Reservation Level Tchebycheff Procedure (RLTP), which is one of the interactive multi-objective decision-making techniques. Subsequently, the obtained results will be compared with those of the single-objective models to ...

The objectives of flood control, power generation, water supply and ecology for reservoir operation are neither completely coordinated nor opposed, its optimal decision-making is very complicated. This study proposed a method multi-objective optimization multi-attribute decision making (MODRO). correlation analysis was used to analyze the competitive relationship among extracted objectives, mod...

evaluating and selecting alternatives investment projects needs considering all relevant and important aspects. in traditional methods, the focus is just on tangible monetary criteria. also in the traditional methods, either all the information’s about factors must be known precisely or sufficient objective data must be available for applying probability theory. in this paper, a combinative app...
