The existing group consensus models for solving the group decision making (GDM) problems with [0,1] reciprocal preference relations are always on the basis of absolute deviation measures. In this paper, we define the individual consistency accuracy index and the group consensus accuracy index based on the relative deviation measure, which can measure the relative precision of difference among the...
Linguistic group decision making (GDM) always focuses on balanced linguistic terms sets, which are uniform and symmetrical. However, in real life there exist GDM problems that need to be assessed by linguistic terms sets with non-symmetrical and non-uniform distributions. The purpose of this paper is to present an unbalanced linguistic generalized power ordered weighted averaging (ULGPOWA) operator...
Motivated by the optimal solution of a deviation model proposed in this paper, we develop the generalized linguistic weighted logarithm averaging (GLWLA) operator and the generalized linguistic ordered weighted logarithm averaging (GLOWLA) operator in the group decision making under the linguistic surrounding, which are obtained by constructing the mathematical model for minimizing the deviation.
Police Patrol is a very useful method for managing the social security. Many researches focus on how to obtain the best strategy for police patrol. We got this research topic from The Sixth National Post-Graduate Mathematical Contest in Modeling. In the proposed approach, Greedy Policy and Randomized Strategy are combined with Genetic Algorithm to solve these problems, simulation result shows the...
This paper presents a simulated annealing based rule extraction algorithm (SAREA) for credit scoring problems. In previous studies, several classification algorithms like statistical models, mathematical programming, and artificial intelligence techniques have been used. This paper aims to illustrate the ability of SA to develop accurate classifiers for credit scoring problems. The use of SA is a...
