An Improved TOPSIS Method Based on Connection Degree
Zongfang Zhou · Systems Engineering · 2008
This paper proposes an improved TOPSIS method for multi-attribute decision-making,in which the ideal point and negative ideal point are regarded as an opposit set in a system both having certainty and uncertainty.When inspects the connection degree between the objective project and the ideal point or negative ideal point is inspected,the existence of an opposit set is fully considered.By introducing the connection vector distance, the relative similarity scale is calculated,which to some degree improves the traditional TOPSIS method.An application example is given to illustrate and verify the feasibility and validity of the proposed method.
