The ELECTRE method based on interval numbers and its application to the selection of leather manufacture alternatives∗

چکیده
The decision making problem with interval numbers is an important topic of uncertain multiple attribute decision making. A difficulty to solve the interval decision making problems is the ranking method of interval numbers, because among the interval numbers exist cross, it’s difficult to ranking the alternatives directly. This paper studied how to make use of the traditional method for certain circumstance to solve MADM with interval numbers. Then we proposed an enhanced ELECTRE method based on interval numbers. Considering the particularities of interval numbers, we use possibility degree for ranking alternatives, establish the concordance dominance matrix, discordance dominance matrix and aggregate dominance matrix, then eliminate the inferior alternatives. This method can be used for MADM, in which the attribute values are in the form of interval numbers, and it solved the hardness in ranking interval numbers in the traditional method. We solved a selection problem of leather manufacture by this method, and illustrated its application in real-life.
