infrastructure development being the major construction activity undertaken with the support of the government to eradicate poor transport infrastructure, to cater to ever-increasing population, to reduce the usage of own vehicle and environmental impact thereof, the concept of mass rapid transit system came into existence. among the various mass rapid transit system modes, metro rail construct...

As a fuzzy set extension, the hesitant set is effectively used to model situations where it is allowable to determine several possible membership degrees of an element to a set due to the ambiguity between different values. Some new hesitant fuzzy operational rules are introduced based on the Hamacher t-conorm and t-norm, whereby we present a multi attribute decision making method under hesitan...

Multi attribute decision making methods are considered as one of the most useful methods for solving ranking problems. In some decision making problems, while the alternatives for corresponding criteria are compared in a pairwise comparison manner, if the criteria are inherently fuzzy, debates will arise in ranking alternatives due to the closeness of the values of the criteria. In this researc...

Cognitive biases affect decision making in systems engineering (SE). Daniel Kahneman, 2002 Nobel laureate for his pioneering studies of cognitive biases in economic decision making, describes many disparate cognitive biases as abstractly belonging to one higher-level bias, that of attribute substitution. Attribute substitution occurs when an answer about a target attribute is unconscientiously ...

This study seeks to better understand bidding decision support in multi-attribute reverse auctions. It views bidding as a decision making process and attempts to determine how tools that aid different stages of the decision making process affect the quality of the bids submitted. Two experiments reveal that decision support tools that impact all the stages of a bidder's decision making process ...
