Dynamic grey target decision making method with three-parameter grey numbers

Dynamic grey target decision making method with three-parameter grey numbers PurposeA new method about dynamic decision problems with three-parameter grey numbers from other angle of view is presented, not only aggregates the attribute values of alternatives all the periods, but also excavates changes of attribute values about alternatives between the adjacent periods.Design/methodology/approachWe adopts grey target method to calculate the distance between every alternative and the best, worst bull’s eye, the distance between change series and the best, worst change bull’s eye, then both distances can be aggregated to reflect information about two aspects.FindingsThis dynamic decision making method not only aggregates the existing state of alternatives all of the stages, but also excavates the change information from vertical and horizontal direction, the decision result conforming to decision maker’s psychological behavior is obtained though adjusting the priority parameter.Originality/valueThe paper considerers on change of alternative’s attribute values from one period to the next period, and the dynamic characteristic has been reflected adequately. The grey target decision making method reflects the distance between alternative and bull’s eye, the comprehensive target distance between alternative and positive, worst bull’s eye about change series are separately provided.

Abstract

PurposeA new method about dynamic decision problems with three-parameter grey numbers from other angle of view is presented, not only aggregates the attribute values of alternatives all the periods, but also excavates changes of attribute values about alternatives between the adjacent periods.Design/methodology/approachWe adopts grey target method to calculate the distance between every alternative and the best, worst bull’s eye, the distance between change series and the best, worst change bull’s eye, then both distances can be aggregated to reflect information about two aspects.FindingsThis dynamic decision making method not only aggregates the existing state of alternatives all of the stages, but also excavates the change information from vertical and horizontal direction, the decision result conforming to decision maker’s psychological behavior is obtained though adjusting the priority parameter.Originality/valueThe paper considerers on change of alternative’s attribute values from one period to the next period, and the dynamic characteristic has been reflected adequately. The grey target decision making method reflects the distance between alternative and bull’s eye, the comprehensive target distance between alternative and positive, worst bull’s eye about change series are separately provided. And the final target distance reflecting both existing state and change trend is constructed.
