Partial Ordered of Interval Grey Number and Its Application

摘要：

This paper is concerned with the question of ranking a finite interval grey number set. A method is proposed which is based on Hasse diagram technique (HDT) for partial order ranking and its linear extension decision tree. The main idea is firstly to identify the Hasse diagram of the interval grey sequence and obtain its linear extension decision tree, secondly to accumulate rank frequency for each element. To determine the rank of elements, this paper proposes a new method which uses total area of accumulate function, and for the first time the methods is applied on grey relational analysis, whose sequences contain interval grey number or interval grey number and precision number mixed-emergence. At last, an example shows this method is effective in grey relational analysis.
