An extended evaluation method for the decision-making problems of alternatives is introsuced by means of extension theory. The extended evaluation method can carry out the decision-making problems of the alternatives based on matter-element models and extended relational degrees. The matter-element model of the desired alternative (ideal alternative) and the matter-element models of alternatives are...
Because the risk factors cannot be accurately measured it is very difficult to evaluate the risk of supply chain. By introducing hesitancy degree into the risk evaluation process, an intuitionistic fuzzy model is developed to describe the problem. With this model, an algorithm is proposed to evaluate the risk of supply chain. Example shows that the proposed method is superior to the existing ones...
In view of the practical problems in multi-attribute decision-making, a method based on three-parameter vague sets is proposed. Firstly, three-parameter vague set is introduced to make up for the shortage of the original vague set in expressing fuzzy information, and the method for finding core is proposed. Secondly, the method that indicator value described by linguistic variables is transformed...
In regard to the multiple attribute decision making problems with the information about attribute weights incompletely known under the intuitionistic fuzzy environment, the score function and accuracy function are introduced. The decision making matrix with the attribute value expressed by form of intuitionistic fuzzy number is transformed into the score matrix of the alternatives. Then according...
In this paper, we design a queuing system by calculating the best policy to be implemented regarding publicity decisions by using Markov chains with fuzzy states. To this end, first we calculate the steady-state probabilities when the states of the Markov Chain become fuzzy, and next we illustrate by an example the theoretical results previously obtained. In the example, we apply the linear programming...
