Quality Cement Bricks Selection Using Apex Angle and Fuzzy Linguistic Information

Abstract

This Study Describes Technique for Selecting Good Quality Cement-Bricks. Brick is an essential material in the construction industry. Cement-Bricks are created locally, therefore it is essential to determine which ones are of the highest quality cement-bricks. Cement bricks have almost the same rigidity as Red Bricks. They are also made locally so it needs to identify which ones are the best quality ones. Poor quality bricks can be broken easily or even cause cracks during construction. Under stresses, they are often stronger than ordinary bricks. However, this is highly dependent on the quality of their manufacturing and individual elements. To aggregate individual decision maker’s opinions into a collective opinion, the intuitionistic fuzzy averaging operator is utilized. Six criteria are used for the screening process, and they are based on expert opinions. The categories are as follows: hardness, pigment, shape, brick strength, cost and carrying cost. The majority of significant choices in industries are made by a group of specialists. Preferences and other human judgments are frequently ambiguous and cannot be quantified in precise numerical values. This research provides a fuzzy technique inside a linguistic framework to find the best answer for Multi Criteria Decision Making issues. An apex angle technique based on fuzzy trapezoidal numbers is presented to accomplish this.
