Selection of mine development scheme based on similarity measure under fuzzy environment

Mine development scheme selection is an important project in mine construction, as the benefit of a mine is directly affected by the quality of the scheme. In this paper, we consider the selection problem of mine development scheme under fuzzy environment. Firstly, linguistic neutrosophic numbers (LNNs) are chosen to fully describe people's linguistic evaluation information. To advance the following study, a new similarity measure of LNNs based on consistency degree is defined, and some important properties are also proved. Then, a new method based on similarity measure is proposed to cope with linguistic neutrosophic decision-making issues. It contains two weight determination models. One model takes the advantages of majority rule to calculate the experts' weights objectively. Another model uses the idea of the technique for order preference by similarity to ideal solution to obtain the weights of criteria. Lastly, when the evaluation index system of mine development scheme selection is constructed, the feasibility and strengths of our approach are indicated through an illustration and some related comparisons.
