vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. the problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. this paper propose...

Objective: In all societies, adolescents are the most vulnerable age group to addiction. Decision-making styles and attitude toward substances can play an important role in the tendency of adolescents to addiction. The aim of the current study was to investigate the role of decision-making styles and attitude toward substances in predicting the potential addiction among adolescents. Methods: I...

This study proposes a novel hybrid multiple-criteria decision-making (MCDM) method to evaluate green suppliers in an electronics company. Seventeen criteria in two dimensions concerning environmental and management systems were identified under the Code of Conduct of the Electronic Industry Citizenship Coalition (EICC). Following this, the Decision-Making Trial and Evaluation Laboratory (DEMATE...

Online auctions play an important role in today’s e-commerce for procuring goods. The proliferation of online auctions has caused the increasing need of monitoring and tracking multiple bids in multiple auctions. This paper investigates the application of self adaptive genetic algorithms on a flexible and configurable heuristic decision making framework that can tackle the problem of bidding ac...

Interavl type-2 fuzzy numbers (IT2FNs) are used in many real problems such as multiple attribute decision making (MADM) problems, to model the opinions/judgments of experts. This paper, using centroid points and uncertainty degrees of IT2FNs, presents a new method to rank them. Also, we present new methods based on Choquet integral and various types of Power average to aggregate a set of IT2FNs...

analytic hierarchy process (ahp) has been criticized considerably for possible rank reversal phenomenon caused by the addition or deletion of an alternative. while in many cases this is a perfectly valid phenomenon, there are also many cases where ranks should be preserved. our findings indicate that using the geometric mean reduces the variance in ratings substantially; hence, yielding lower i...

the rapid development of internet and electronic businesses have stimulated the banking sector towards encouraging customers to internet banking (ib), however, the evidence indicates a lack of interest in the use of ib services. therefore, this paper aims to identify affecting factors on customer adoption from ib and measure the influence of each factor on ib adoption. based on an explorative l...

in most of the multi–criteria decision–analysis (mcda) problems in which the choquet integral is used as aggregation function, the coefficients of choquet integral (capacity) are not known in advance. actually, they could be calculated by capacity definition methods. in these methods, the preference information of decision maker (dm) is used to constitute a possible solution space. the methods ...
