Supporting the decision of a group in engineering design is a challenging and complicated problem when issues like consensus and compromise must be taken into account. In this paper, we present the foundations of the group hypothetical equivalents and inequivalents method and two fundamental extensions making it applicable to new classes of group decision problems. The first extension focuses o...

Properly evaluating the overall performance of tubular scraper conveyors (TSCs) can increase their overall efficiency and reduce economic investments, but such methods have rarely been studied. This study evaluated the overall performance of TSCs based on the technique for order of preference by similarity to ideal solution (TOPSIS). Three conveyors of the same type produced in the same factory...

A fundamental step in decision analysis is the accurate representation of the decision maker’s preferences. When the decision situation is deterministic, each alternative leads to a single prospect (consequence). A prospect may be characterized by one or more attributes, such as health state and wealth. A value function that ranks the prospects is sufficient to rank order the decision alternati...

A typical approach to handle the complexity of multi-faceted decision-making problems is to use multiattribute decision-making (MADM) methods based on pairwise comparisons. Fuzzy set theory has also been employed to cope with the uncertainty and vagueness involved in conducting the comparisons between components of a decision model. An important issue regarding the reliability of the output is ...

Over the past several decades, researchers in psychology, neuroscience, marketing, and economics have been keen to understand context effects multialternative, multiattribute decision making. These occur when choices among existing alternatives are altered by addition of a new alternative choice set. The violate classic theories led development computational mathematical models that explain how...

Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowl...

Determining the safety input structure is essential to achieve efficient resource utilization and safe production of coal enterprises. In this paper, system evaluation method, TIFNCWBHG-MAGDM, proposed evaluate It based on integration intuitionistic triangular fuzzy numbers (TIFNs), TIFNs Compound Weight Bonferroni Hybrid Geometric (TIFNCWBHG) operator, multiattribute group decision-making (MAG...

GAI networks are a graphical model, both compact and expressive, for representingthe preferences of a Decision Maker in the context of Multiattribute Decision Making,i.e., in situations where the set of alternatives among which the Decision Maker has tomake decisions are described as a set of attributes (or features). GAI network's graphi-cal structures are exploited to deve...

The English classroom teaching effect evaluation is looked as the multiattribute group decision-making (MAGDM). Thus, a useful MAGDM algorithm needed to cope with it. Depending on classical GRA process and interval-valued IFSs (IVIFSs), this study builds IVIF-GRA assess effect. First of all, concepts IVIFSs are reviewed. In addition, weights criteria derived through CRITIC method. Afterwards, m...
