Abstract

Based on the continuous ordered weighted geometric (COWG) operator, a new algorithm is proposed to derive the weights from interval reciprocal comparison matrices. The obtained weights are dependent on the corresponding expected reciprocal comparison matrix associated with an attitudinal character. In order to make the weights be reliable, a method of making the expected reciprocal comparison matrices own consistency or acceptable consistency is given. Numerical results are further calculated to show the feasibility of the new algorithm and compare with other known procedure. A sensitivity analysis with respect to the attitudinal character is made and shown graphically.
