Synopsis

The similarity measure is a very efficient tool to determine the degree of closeness between two sets of objects. It has found successful applications in various practical areas, including pattern recognition, decision-making, clustering analysis, and image processing. Linguistic picture fuzzy sets (LPFSs) provide a more prominent modeling capability to describe qualitative uncertain information effectively. This paper aims to define novel similarity measures between linguistic picture fuzzy sets and explore their applicability in decision-making situations. To do so, we define two new similarity measures between LPFSs and prove their basic mathematical properties to be valid similarity measures in linguistic picture fuzzy information context. Next, a multiple attribute group decision-making method is developed based on the proposed similarity measures and illustrated with the help of a numerical example. A comparative study with existing methods is also carried out to validate the results.
