Abstract: The definition of interval rough number, obeying the normal distribution, is given and the connection number algorithms are added. A connection number model is transformated by establishing interval rough number mean-variance and using the uncertainty theory of the set pair analysis. For the attribute values are interval rough number and attribute weights are known, a multiple attribute decision making method based on connection number is proposed. Then the decision-making steps are given. Finally, a numerical example is given to show this approach is effective, practical and simple.

Key words: interval rough number, connection number, multiple attribute decision making, normal distribution
