Fuzzy multi-objective and groups decision method in optimal selection of landslide treatment scheme

Abstract

Several measures can be used to landslide control. Therefore, the optimal selection of landslide treatment scheme is a key problem in the landslide treatment design. This paper analyzed the key restricting factors of the landslide treatment scheme. Based on decision theory, fuzzy set theory, and case theory, the fuzzy multi-objective and lattice-ordered groups decision method were applied to solve the problem of optimal selection of landslide treatment schemes. Taking the Chaancun landslide treatment schemes as example, the theory of the limited feasible decision-making methods and the calculation process were determined. Results show that the fuzzy multi-objective and lattice-ordered groups decision method is feasible in the optimal selection of landslide treatment scheme, because this method can normalize the qualitative and quantitative indexes into quantitative indexes. Consequently the optimal selection result is highly objective. Therefore, this paper is significant to the comparison and optimization of landslide comprehensive treatment schemes.
