An aggregate method of grey connection number based on vague linguistic interval

The paper proposed new ideas and algorithms for the aggregate problem of connection number of vague linguistic interval based on connection number theory of set pair analysis. The main idea is to transform Vague language interval variables into the countenance, difference and opposite connection numbers of set pair analysis, and transform the corresponding decision matrix into grey connection number matrix in order to set up trustiness function and uncertain factors of score functions in grey connection number of Vague linguistic interval, decisions have been made by sorting the value of aggregate uncertain factors. Some numerical examples have been given to illustrate the calculation procedure and process of the proposed algorithm.
