Attribute weighting is a task of paramount relevance in multi-attribute decision-making (MADM). Over the years, different approaches have been developed to face this problem. Despite effort community, there lack consensus on which method most suitable one for given problem instance. This paper second part two-part survey attribute methods MADM scenarios. The first introduced categorization five...

Based on picture fuzzy sets (PFSs), we use a mathematical model to tackle such types of problems when person has opinions like yes, no, abstain, and refusal. The spherical is more flexible practical than the model, as it enhances space uncertainty. It broadens vague information evaluated by decision makers since graphs are pictorial representation information. Graphs tool represent network. To ...
