The Study of HIV Diagnosis Using Complex Fuzzy Hypersoft Mapping and Proposing Appropriate Treatment

Abstract

HIV is still a global epidemic more than 40 years after it was described initially, impacting mainly Sub-Saharan Africa, Southeast Asia, and Latin America. HIV is an RNA retrovirus that wreaks havoc on the immune system, making the infected individual vulnerable to opportunistic pathologies. For the diagnosis and therapy of infected patients, several models have been proposed in literature. The main goal of this paper is to present an innovative mathematical model for diagnosing and treating this pandemic based on a unique flexible fuzzy-like structure called the Complex Fuzzy Hypersoft (CFHS) set, which is a glued structure of complex fuzzy (CF) set and hypersoft sets (an extension of soft set). To address ambiguity and unclear data, the basic theory of CFHS set is created, which examines the amplitude term (A-term) and phase term (P-term) of complex numbers concurrently. In two aspects, this new fuzzy-like hybrid theory is adaptable. First, extending membership function values to the unit circle on an Argand plane and including an extra term, the P-term, to suit the recurring character of data that provide access to a wide range of membership function values. Second, it categorises the different attributes into matching disjoint attributevalued sets for a more straightforward interpretation; it's tough to identify which HIV is and how serious it is after looking at the HIV side effects. To deal with such problems, the CFHS set, and CFHS-mapping with its inverse mapping is utilised. These concepts are practical and required for adequately assessing the situation using mathematical modelling. This investigation shows a relationship between symptoms and medications, making the story easier to follow. A table is constructed for the HIV kinds based on a fuzzy interval of [0, 1]. The calculation is based on CFHS-mapping, which correctly diagnoses the condition and prescribes the best medicine. A generalised CFHS-mapping is also offered, which can assist a specialist in extracting the patient's improvement record and estimating how long it will take to eradicate the infection.

Identification and Prioritization of DevOps Success Factors Using Bipolar Complex Fuzzy Setting With Frank Aggregation Operators and Analytical Hierarchy Process

“…Thus, handling such sort of information is very complicated for a decisionmaker, for this, every expert has needed to change the range of FS, therefore, the main theory of complex FS was diagnosed by Ramot et al [35]. Certain applications of CFS have been done in shape, called distance measures [36], complex fuzzy hypersoft sets [37], neighborhood operators for CFS [38], algebraic structure [39], and entropy measures [40][41][42]. By utilizing the two-dimension data, the comprehensive data can be expected in one set, and hence, loss of data can be prevented.…”

Distance and Similarity Measures Using Max-Min Operators of Neutrosophic Hypersoft Sets With Application in Site Selection for Solid Waste Management Systems

“…In strategic decisionmaking, cosine similarity measures are given by Wei [69]. Cotangent similarity measures of single value neutrosophic soft set and its application in fault diagnosis in the steam turbine are given by Ye et al [33], Khan et al [70], and Ahsan et al [71] CMFHS mapping and applied in HIV diagnosis with treatment. Jafar et al [72] proposed Trigonometric Similarity measures and applied them in the renewable energy source selection.…”

An Optimized Complex Fuzzy Hypersoft Set System Based Approach for the Evaluation of Strategic Procurement Techniques for Fuel Cell and Hydrogen Components

“…He extended this approach by re-envisioning SS as a multi-attribute procedure and expanding it to the HSS. In a neutrosophic context, Saeed et al [30], [36], [63], [66]- [69] presented the concepts of Hypersoft (HS) and its applications in real-life scenario. There are some other theories [62]- [64] which have been developed to discuss the hybrid structures of fuzzy-like environments.…”
