decision making and problem solving are especially important skills for business and life. as an innovation leading corporate, sony has gradually lost their superiority in innovation and core competences under more and more intensive competition environment. this report is made to investigate sony current procedure on its solving problems and making decision, analyze approaches and tools used b...

As far as medical diagnosis problem is concerned, predicting the actual disease in complex situations has been a concerning matter for the doctors/experts. The divergence measure for intuitionistic fuzzy sets is an effective and potent tool in addressing the medical decision making problems. We define a new divergence measure for intuitionistic fuzzy sets (IFS) and its interesting properties ar...

Bilevel linear programming  is a decision making problem with a two-level decentralized organization. The textquotedblleft leadertextquotedblright~ is in the upper level and the textquotedblleft followertextquotedblright, in the lower. Making a decision at one level affects that at the other one. In this paper, bilevel linear programming  with inexact parameters has been studied and a method is...

A project is normally undertaken to produce a product or facility that has been deemed necessary to satisfy a need. Within the total life cycle of a project, from start to finish, the period that often receives less than the attention and effort it deserves is the initial start-up phase. The start-up or concept phase is defined as that period prior to identifying that a project exists, and befo...

Analytic results indicate that many heads often can be better than one even when none o f the added heads is as individually compe ten t as the first . We define individual competence (accuracy) in a dichotomous choice situation as the probability Pi of making the 'correct' or 'better' choice.~ Condorcet (1785) shows that if each person has equal competence, and if that competence, pi, is great...

aim and back ground: impulsivity and risky decision making is a core element of plenty of individual and social deficits. on the other hand, history of attention deficit disorder and hyperactivity has been reported in many people with these problem particularly addiction. decision making requires basic cognition function such as inhibition, working memory and attention. the aim of the current s...

considering the major change occurred in business cells from plant to “chain” and the critical need to choose the best partners to form the supply chain for competing in today’s business setting, one of the vital decisions made at the early steps of constructing a business is supplier selection. given the fact that the early decisions are inherently strategic and therefore hard and costly to ch...

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...
