Abstract: Classic Multi-Criteria Decision Making（MCDM） method is unable to deal with the dynamicity in real world. Also, it is difficult to reflect the feedback action that Alternative Cluster（AC） dominates Criteria Cluster（CC）. To overcome the above mentioned drawbacks, in this paper a multi-criteria group decision making approach with variable weights in a dynamic environment is suggested by synthesizing both data envelopment analysis and analytic network process. Compared with classic MCDM method, the outstanding advantages for the approach lie in following three points. A dynamic evolvement mechanism for MCDM model is proposed. A novel group information distilling way is given by analyzing these statements that each alternative lies in criteria to express expert preference, which ensures no loss of every information. It may realize the decision with variable weights for alternatives, therefore, nonlinear interaction relation between AC and CC could be well reflected. The approach is validated to be feasible and scientific and can be well applied to solve the real world dynamic decision issues, such as selecting dynamic disaster relief alternatives, supplier dynamic evaluation, etc.
