This paper presents a decision making algorithm using Bipolar valued Q-fuzzy set and focusses its application in civil engineering for the selection of cement with its influenced characters. It can be applied for other such scenarios. The Bipolar valued Q-fuzzy takes the positive and negative values for each and every object in the selected set with respect to the constraints. The opinion of the experts in the optimal selection of the cement is analyzed in this study using Comprehensive Index of a Bipolar Valued fuzzy number. © IAEME Publication.
