The application of FANP in selecting an optimal construction project

An index system for selecting an optimal construction project is established. Due to the uncertainty and the inaccuracy of information during the evaluation process, an evaluation selection model based on fuzzy analytic network process method is proposed. The weight of each index, including the weight of the criterion level indicators, the weight of independent sub-indices and the weight of dependent sub-indices are determined by fuzzy preference programming method with the help of Matlab software. Meanwhile, the unweighted supermatrix is built for those interactional indicators, and the limit supermatrix is calculated after randomizing the unweighted supermatrix. Accordingly, a comprehensive weight of each index and the final score of each alternative can be calculated. Finally, an example is given by proposed method, and the result is shown that it can deal well with this kind of problems.
