A Fuzzy Multi-Criteria Decision-Making Approach for Grading of Raw Jute

ABSTRACT

Raw jute being a bio-material has a huge level of variability and impreciseness. A scientific method for grading of raw jute considering the underlying impreciseness in jute quality parameters is proposed in this work. The crisp concepts of multi-criteria decision-making are inadequate to model real-life situations. This study proposes a fuzzy multi-criteria group decision-making method that employs the proficiency of three decision-makers to extenuate the fuzziness perceived in quality parameters of raw jute. Strength, defect, root content, color, fineness and bulk density are regarded as criteria for grading of raw jute. Ten raw jute lots are ranked by the intuitionistic multi-criteria multi-expert decision-making method. The ranking of jute lots attained by this method shows a significant agreement with the ranks devised by the technical experts. Hence, the intuitionistic approach emerges as a more profound method for grading of highly heterogenic bio-material like jute.

摘要

黄麻原料是一种生物原料，具有很大的变异性和不精确性。本文提出了一种考虑黄麻品质参数潜在不精确性的黄麻原料分级方法.多准则决策的清晰概念不足以模拟现实情况.本研究提出一种模糊多准则群决策方法，利用三位决策者的熟练程度，来扩大生黄麻品质参数的模糊性.强度、缺陷、根含量、颜色、细度和容重是黄麻原料分级的标准.采用模糊多准则多专家决策方法对10批黄麻进行排序.通过该方法得到的黄麻批的排序与技术专家设计的排序有着重要的一致性.因此，模糊多准则决策方法成为对黄麻等高异源生物材料进行分级的更为深入的方法.
