Now a day decision making plays a major role in deciding the execution of any task. Two key tools are available to serve the purpose of decision-making. These include AHP as well as TOPSIS, both falls under Multi Criteria Decision Making (MCDM) tools. These techniques are now also brought in the field of civil engineering. MCDM techniques are used in various applications of civil engineering. This paper presents comparison of AHP and TOPSIS for making final decisions for the best concrete mix with fibres of steel and basalt available with different proportions. The comparison is made on the tests of split tensile strength, compressive strength and flexure results. Results of the experiment are used to validate results of AHP and TOPSIS. Optimum hybrid mixes for mechanical properties is M-S0.5-B0 at 28 days.

多准则决策工具在混凝土配合比选择中的应用

现在，一天的决策在决定任何任务的执行中起着重要作用。有两个关键工具可用于决策目的。其中包括 AHP 和 TOPSIS，两者都属于多标准决策 (MCDM) 工具。这些技术现在也被引入土木工程领域。MCDM 技术用于土木工程的各种应用。本文介绍了 AHP 和 TOPSIS 的比较，以便为使用不同比例的钢纤维和玄武岩纤维做出最佳混凝土混合料的最终决定。对劈裂抗拉强度、抗压强度和挠曲结果的测试进行了比较。实验结果用于验证AHP和TOPSIS的结果。机械性能的最佳混合混合物是 M-S0.5-B0 在 28 天。
