An Extension Preprocessing Model for Multi-Criteria Decision Making Based on Basic-Elements Theory

Multiple Criteria Decision-Making (MCDM) are often contradict between their goals and criteria. Compromised or satisfied solutions usually cannot meet the practical needs well. We found the problem lies on the assumption that goals and constraints are fixed and reasonable but in fact they are extendable in practice. We present an extension preprocessing model for MCDM based on basic-elements theory. Several steps for the preprocessing of MCDM is introduced to extend the constraints, criteria or goals to obtain win-win solutions by implication analysis and transformations. It gives a way for exploring win-win solutions by extending the multi-direction information and knowledge of the constraints or goals supported by data mining and Extenics.
