Abstract

This paper presents the grading of raw materials i.e. cotton fibres in textile spinning industry using multi-criteria decision making (MCDM) approach. Traditionally, some quality indices, based on crude formulas, have been used in the spinning industry to evaluate the raw materials with respect to the properties ofthe final product i.e.yarn. These methods oftenfail to produce desired results due to the inherentflaws therein. In this work, the weightage ofthe decision criteria are decided by the Analytic Hierarchy Process (AHP) and the Elimination and Choice Translating Reality (ELECTRE) outranking approach has been used to rank the different types of cottons. The proposed approach yields good rank correlation between the quality value of cottons and yarn breaking strength. Moreover, the approach is flexible and can be modifiedwith ease depending upon the technology of spinning beingfollowed in the industry.
