A linear goal programming method for calculating weights in the interval analytic hierarchy process

Based on the incorporation of differences between the actual interval and the judgment interval given by the experts' pairwise comparison, the problem of calculating weights in the interval AHP is studied in three aspects. And on the basis of the solution to a linear goal programming three new algorithms for the interval weight of each alternative derived from interval judgment matrix are proposed respectively. Finally, the effectiveness of these algorithms is illustrated by the solution to a practical example.
