To identify the best alternative in multicriteria decision-making problems, a multicriteria fuzzy decision-making method based on the weighted correlation coefficient of interval-valued intuitionistic fuzzy sets (IVIFSs) is established in which criterion values for alternatives are IVIFSs and the criterion weights are known information. With the definition of ideal and anti-ideal weighted correlation...
A novel score function is presented by taking into account the expectation of the hesitancy degree of interval-valued intuitionistic fuzzy sets (IVIFSs). And a deviation function is defined considering the variance of the hesitancy degree of IVIFSs. A new method for ranking interval-valued intuitionistic fuzzy numbers is then established based on the score function and deviation function. The proposed...
In this paper, we develop the multi-products multi-constraints newsboy problem with fuzzy demands considering the total discount situation. Since the demands of products are often fuzzy in the real world, the profit of the newsboy is fuzzy too. A new model is presented for multi-products multi-constraints newsboy problem in fuzzy environment (FM-PM-CNP). The objective function of proposed model is...
In this paper we present a new method for solving multicriteria decision making problem in an interval-valued intuitionistic fuzzy environment. Firstly, we introduce a score function and an accuracy function for ranking the order of interval-valued intuitionistic fuzzy sets. Then, we obtain the criteria's optimal weights via a linear programming model to rank the alternatives and select the best one(s)...
