Irregularity indices are usually used for quantitative characterization of the topological structures non-regular graphs. In numerous problems and applications, especially in fields chemistry material engineering, it is useful to be aware irregularity a molecular structure. Furthermore, evaluation graphs valuable not only structure-property relationship (QSPR) structure-activity (QSAR) studies but also various physical chemical properties, including entropy, enthalpy vaporization, melting...

Here we have employed three trapezoidal fuzzy numbers (TT2FNs) to deal with a multi-criteria decision making (MCDM) problems. The introduced technique takes into consideration the left and right areas of types membership memberships involved in TT2FNs also considers risk attitu de maker. presented method is more generalized since used TT2FNs, which are effective capturing uncertainty than IT2FSs, just like triangular has better representational power simple interval numbers. We considered...

Multi-criteria decision making (MCDM) problems have been solved involving various types of fuzzy sets. We know that interval type-2 sets (IT2FSs) are the most representative known since they ability to capture both type linguistic uncertainties associated with a word n amely, intra-personal and inter-personal respectively. Here for MCDM problems, we will use three trapezoidal numbers (TT2FNs) which more effective in capturing uncertainty than IT2FSs, just like triangular has better...

Topological indices (TIs) assign a numeric value to graph or molecular structure. Due their ability predict the physiochemical properties of graph, several TIs have been introduced and studied, mainly based on degree distance.

Abstract In recent years, several structure-based properties of the molecular graphs are understood through chemical graph theory. The <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"><m:mi>G</m:mi></m:math> G a molecule consists vertices and edges, where represent atoms in edges bonds between these atoms. A numerical quantity that gives information related to topology is called topological index. Several indices, contributing theory, have been defined vastly studied. Recent inclusions...
