Based on the characteristic of interval number, the distance of interval number is defined. The distance of interval number is proved to be the extent of real number distance when the interval number is real number. Based on the grey incidence degree theories, the computing method for the degree of interval number incidence is developed. The grey incidence analysis theory is extened from the real number sequence to the interval number sequence and the development of the grey incidence theories is promoted. This paper studies the incidence decision making problems of multi-attribute interval number and models the incidence decision making model of multi-attribute interval number. The model gets rid of the difficulty to seek dummy ideal scheme and negative ideal scheme, and seek the optimum decision making scheme in the whole system. Meanwhile, the model is easy to be implemented in computer program. Finally, its validity and its practicability are examined with examples. The method offers a new scientific and practical decision making approach for solving the decision problem with multi-attribute interval number.
