Abstract

In modern civilization, individuals are increasingly concerned with evaluating the quality of medical services. Evaluation of the quality of medical services enables medical care providers to monitor and improve their service quality. The evaluation of medical service quality is efficiently addressed by the novel concept of Aczel–Alsina operators in an intuitionistic hesitant fuzzy (IHF) environment as multicriteria decision-making (MCDM) problem. Thus, this paper presents the IHF Aczel–Alsina weighted geometric operators for IHF information. We first apply the Aczel–Alsina norms to IHF scenarios and present novel operations of intuitionistic hesitant fuzzy sets. This article develops a unique strategy for evaluating the quality of medical services based on the specified operators, including a quantitative framework for evaluating medical service quality and a novel MCDM technique. Finally, this article presents a numerical example of the novel approach used to evaluate medical services for hospitals and compares it to conventional MCDM methods to highlight the suggested superiority method. According to the comparative results, our strategy outperforms the insufficiency of lacking decision flexibility in the existing MAGDM method.

1. Introduction

In light of the significant development of medical services and the healthcare industry, the society is becoming more concerned about the quality of medical treatment and urging companies to enhance quality [1]. Additionally, the World Health Organization declared in 2000 that assessing a medical service provider’s quality has been a worldwide problem [2]. Healthcare practitioners need an appropriate and effective approach for evaluating the quality of healthcare services in order to monitor and enhance the quality of medical services they provide. If patients want to receive better healthcare, they should evaluate various hospitals using a variety of factors in order to choose the best option. Numerous researchers have devoted to studies on the assessment of medical service quality on the basis of this framework. For example, Shieh [3] utilised the DEMATEL approach to identify the essential aspects in the quality of medical services, such as the atmosphere, registration system, and appearance. Mccarthy [4] classified medical service quality like respect and care, effectiveness and continuity, suitability, and communication, efficiency, meals, initial impression, and staff versatility. By combining the work of the previous researchers, Fei et al. [5] presented a set of medical quality assessment.

The method of employing expert assessment data to analyse, rank, and select the best solutions using a specific decision-making (DM) approach is known as multiattribute group decision making (MAGDM) [6–8]. Giving pertinent information is a necessary step in the decision-making process, as it is selecting one DM technique over others. As it is impossible to anticipate the future and because specialists’ knowledge is limited, improving the MADM technique has become a hot topic in today’s DM field [9–11]. While analysing data, the uncertainty and incompleteness are always an issue. For instance, according to the idea of hard sets, an item either belongs to or does not belong to a particular class. However, many things in the real world could not be described in such detail [12, 13].

Since the assessment problem of medical service quality is related to many factors and the evaluation finding is the foundation of decision making (DM) on the selection of medical service provider, it may be regarded as a multiattribute decision-making (MADM) problem [14, 15]. MADM refers to the process of assessing, classifying, and choosing the best options from a set of decision support data and a set of decision support models. The most crucial parts of making a decision are specialists’ knowledge and the choice of applicable decision assistance approaches. Expertise and the complexity of society have necessitated that the expansion and refinement of the MADM technique are better decisions in decision supporting difficulties. In the DM process, there is inconsistency and uncertainty, and Zadeh’s [16] idea of fuzzy sets (FSs) provides a highly effective technique to deal with these challenges. Following that, intuitionistic FSs (IFSs) [17] were developed, which used +ve and −ve membership grades to express uncertainty in decision-making processes. When presented with a DM issue, decision makers began to employ IF numbers to indicate their ranking for various choices. As a result, an increasing number of researchers are getting interested in IF data [18–20].

To compile the information gathered from the specialists, we will need to use some aggregation operators (Agop). Some Agops, such as the IF averaging operator, were created by Xu [21]. Some Einstein Agops, such as IFE averaging/geometric operators, were introduced by Wang and Liu [22]. Yu and Xu [23] created a prioritised list of Agops and explored how they could be used to solve DM issues. Liu and Wang [24] used a linguistic IF technique to create several innovative Agops and an algorithm to solve complex uncertain DM situations. Xu and Yager [25] established the decision-making technique using Bonferroni means Agop under IF data.

On the basis of prioritised IF Agop under linguistic data set, Arora and Garg [26] constructed the group DMA. Zhao et al. [27] examined the uses of generalised IF Agops, such as the generalised IF averaing/geometric operators, to deal with uncertainty in Dcmp. Yu [28] demonstrated certain IF Agops depending on confidence levels and solved challenging real-world Dcmps. Yu [29] created the IF Agop and discussed its usefulness in decision making using Heronian mean. Jiang et al. [30] devised a decision-making strategy based on the IF power Agop and the entropy measure. Senapati et al. [31] developed an Aczel–Alsina (Acz-Aln) norm based on some IF Acz-Aln Agops and applied it to the IF MADM process [32]. Khan et al. [33] created new generalised IF soft details Agops and investigated their use in DM.

T-norms and t-conorms (e.g., Algebaric t-norm and t-conorm, Einstein t-norm and t-conorm, Hamacher t-norm and t-conorm) are well-known as essential operations in FSs and other fuzzy systems [34]. Aczel and Alsina established the Acz-Aln t-norm and Acz-Aln t-conorm operations, which offer the benefit of parameter adaptability [35]. The goal of this research is to propose the Acz-Aln t-norm and t-conorm operations, as well as a list of new Agop, in an IHF context, and to develop a MAGDM strategy to solve the favoured ranking of alternatives in MADM utilising these operators. Assessing the quality of medical services as an MCDM challenge is an effective way to equip medical practitioners with a reasonable appraisal. We provide a novel Acz-Aln Agop-based approach for evaluating medical services. Finally, we demonstrate the supremacy of our technique by providing a numerical example and a comparison to the existing approaches. Depending on the outcomes, we can assist governments on how to improve the quality of medical care providers.

1.1. Motivation and Gap of Study

The literature had a large number of AOs based on t-norm (TN) and t-conorm (TCN). Uninorms were first introduced to the FS theory by Deschrijver and Kerre [36]. IF AO was created by Xia et al. [37] using Archimedean TN and TCN.

IF AOs were created by Wang and Liu [22] utilising Einstein TN and TCN. Based on Einstein TN and TCN, Wei and Zhao [38] presented induced hesitant interval-valued AOs. Liu [39] created interval-valued IF (IVIFS) AOs using Hamacher TN and TCN. By utilising Dombi TN and TCN, Ullah et al. [40] established interval-valued TSF AOs. IF power AOs were created by Zhang et al. [41] utilising Frank TN and TCN. This TN and TCN had a significant impact on the use of FSs in decision making. A novel pair of TN and TCN that is more flexible than the previous TN and TCN listed above was initially introduced by Aczel and Alsina [35]. Senapati et al. [42] developed the Aczel–Alsina AOs for the IFS framework as well as for interval-valued IFSs (IVIFSs) and discussed the application to MADM, and both highlight the importance of the Aczel–Alsina TN and TCN due to the variableness of the involved parameters. We can infer from the investigation abovemenioned that the AOs used in MADM are complicated by actual phenomena. Naeem et al. [43] presented the decision methodology based on the picture fuzzy Aczel–Alsina geometric aggregation operators to tackle the uncertainty in decision making problems.

The information should be handled more readily in order to get the optimal alternative in MADM. Moreover, IHFSs operate in a more ambiguity-tolerant environment than IFSs, IVIFSs, Pythagorean FSs (PyFSs), q-rung orthopair FSs (qROFSs), and spherical FSs (SFSs). The usage of Aczel–Alsina TN and TCN in the framework of IHFSs has not yet been discovered. These elements inspire us to formalise the idea of Aczel–Alsina AOs in the design of IHFSs and then investigate how they apply to MADM. Using this structure, the problem is additionally categorised by changing the physical importance of the reference parameters. For the following reasons, many novel aggregation operators (AOs), including the IHF Acz-Aln operations operators, are recommended as follows:(a)IFS and HFS are related ideas that provide IHFS decision makers more latitude.(b)IHFS uses approximate spaces for hesitation as opposed to IFS.(c)Weighted averaging and geometric aggregation operators are unable to account for experts’ levels of knowledge with the examined items when performing initial evaluation; however, IHF Acz-Aln AOs can.(d)The IHF Acz-Aln AOs are simple and cover the decision-making process; therefore, this article aims to address more complex and advanced data.(e)In the suggested work, all flaws are fixed.

The following are the objectives of the paper:(1)In order to make up for the lack of algebraic, Einstein, and Hamacher operations and to depict the relationship between IHFNs, we develop a series of Acz-Aln operations for IHFNs.(2)In order to support IHF data, we develop Acz-Aln Agop to IHF Acz-Aln Agop: IHF Acz-Aln weighted geometric (IHFAWG) operator, IHF Acz-Aln order weighted geometric (IHFAOWG) operator, and IHF Acz-Aln hybrid weighted geometric (IHFAHWG) operator.(3)We developed an algorithm to handle MAGDM problem using IHF information.(4)We used a MAGDM problem regarding the quality of medical care providers to describe the suitability and reliability of the proposed IHF Acz-Aln Agop.(5)The results demonstrated that the developed approach is incrementally more potent and produces more authentic findings than existing approaches.

The following is the order in which the rest of this article is organised. Section 2 discusses the basics of t-norms, t-conorms, Acz-Aln t-norms, IHFSs, and a number of operational principles in the context of IHFNs. Section 3 discusses the Acz-Aln operating rules as well as the characteristics of IHFNs. In Section 4, we interpret several IHF Acz-Aln Agops and discuss their distinguishing characteristics. In the next section, we will look at the MADM problem with the help of IHF Acz-Aln Agop. In Section 6, we present a novel method for assessing the quality of medical services by seeing it as an MCDM problem. The new technique aids in the efficiency and accuracy of assessing the quality of medical services, allowing medical service providers to enhance and amaze their customers. In Section 7, we examine how a parameter influences DM results. Section 8 contrasts the results of the suggested Agop to those obtained through existing Agops, and it summarises the article and makes recommendations for further research.

5. Decision Support Algorithm

In order to validate the utility of the IHF Acz-Aln geometric Agops in this study, a new MCGDM approach is developed to deal with complex ambiguous data in real-life decision support difficulties. The following are the particular measures to take.

Assume that “set of alternatives , and adequately evaluate by a set of attributes . Then, the impotence of attributes is specified by a weight vector such that and .

Let for , be the satisfactory assessment of each attribute for each alternative, where indicates the +ve grade function that the alternative satisfies and indicates the neutral grade function and the −ve grade function sequentially. The decision matrix of IHFNs can be calculated using all evaluation values as follows: .

The created IHF Acz-Aln geometric operators were used to resolve the MCDM problem in this research, and the process for sorting the best raking from alternatives is as follows: Step 1: identify a set of characteristics that are relevant for the evaluation problem being solved. A literature review is conducted to acquire potential evaluation qualities, which are then filtered by a technical committee to produce a suitable list of evaluation attributes. Step 2: normalization yields the normalized decision matrix as follows: where refers to “if is a benefit criterion” and refers to “if is a cost criterion”. Step 3: collected specialist uncertain data: IHFWA/IHFWG to combine the specialist uncertain data in decision support issues, aggregation operators are used. Step 4: illustrate the significance (weighting) of the attributes to be considered using IHF entropy measure as follows: Step 5: aggregated data: developed IHF Acz-Aln geometric operators exploited to aggregate the specialist uncertain data of decision support problems. Step 5(a): exploited IHFAWG operator to amalgamate aggregated data. Step 5(b): exploited IHFAOWG operator to amalgamate aggregated data. Step 5(c): exploited IHFAHWG operator to amalgamate aggregated data. Step 6: according to the score function in Definition 10, the score values of are derived.” Step 7: all options are sorted in highest to the lowest depending on the scores, and the best one with the highest score value is chosen.

6. Numerical Representation of the Suggested Method

We approach an uncertain challenge of assessing the quality of healthcare care in verifying the usefulness and adaptability of the created strategy to the MADM challenge.

6.1. Case Study: Evaluating the Quality of Medical Services

The assessment framework for evaluating the quality of medical services developed in this article contains four parameters. The following provides an explanation of the alternatives for evaluating the quality of medical services:

The focus of this research is nearly entirely on evaluating the medical care process at the level of physician-patient interaction. As a result, it excludes processes that are primarily concerned with the successful delivery of medical care in the community. Furthermore, the administrative components of quality control are not addressed in this study. Many of the studies discussed here arose from the urgent requirement to assess and control the quality of care in organised medical care systems. Nonetheless, these studies will be discussed solely in terms of their contribution to evaluation procedures rather than their broader social objectives. Specific construction standards have a significant impact on health maintenance and enhancement, as well as the safety and comfort of people in health care facilities. Health-care institutions are unusual structures in which several habitats coexist. A wide variety of people, activities in each setting, and risk factors are all implicated in the pathogenesis of a wide range of diseases. Nursing units, operating theatres, diagnostic facilities (radiology units, laboratory units, and so on), outpatient departments, administration areas (offices), dietary facilities, linen services, engineering services and equipment areas, corridors, and passages are all classified using functional organisation criteria. Health professionals, staff members, patients (long-stay inpatients, acute inpatients, and outpatients), and visitors make up the hospital population. The processes include activities particular to health care—diagnostic, therapeutic, and nursing tasks—as well as activities common to many public facilities, such as office work, technological maintenance, and food preparation. Physical agents (ionising and nonionising radiation, noise, lighting, and microclimatic factors), chemicals (e.g., organic solvents and disinfectants), biological agents (viruses, bacteria, and fungi), ergonomics (postures, lifting, and so on), and psychological and organisational factors are among the risk factors (e.g., environmental perceptions and work hours). Four general topics on quality assessment were quite useful in the preparation of this study.(1)Hospital environment : the patients and the hospital are inextricably linked. Patients visit hospital for treatment, and they are happy with the clean environment produced by the providers. The hospital environment is influenced by a variety of elements, including travel accessibility, ward space, ward's quietness, patient and medication care, and environmental characteristics that restrict or improve communications. When a patient’s surrounding is exceedingly loud, he or she may have difficulty sleeping or being comfortable, impairing their ability to heal. The patients like the clean and secure atmosphere provided by the medical service provider. Environmental services (ESs), often known as housekeeping or cleaning services, is a phrase used specifically in healthcare to guide the act of cleaning and disinfecting medical devices, patient rooms, and other public area inside healthcare facilities by highly trained support service workers. ES assist reduce HAIs and prevent diseases from spreading.(2)Medical procedures : a medical procedure is a sequence of actions performed in the provision of healthcare to accomplish a purpose. A medical assessment is conducted to ascertain, quantify, or diagnose a patient’s condition or parameter. The medical procedure is impacted by a number of factors, including the availability of the medical care, the information collected during the assessment, the diagnostic process, and continued health guidance. Due to the sheer risk of becoming infected spreading and/or resource constraints (both apparatus and manpower), the acceptability and capability of conducting abortion interventions and surveillance throughout a pandemic influenza outbreak are likely to be altered. To improve outcomes in critically sick patients treated in and outside intensive care units (ICUs, careful planning for operation execution and monitoring will be required. Although there are little data to support conclusive recommendations, the following standard operating procedure (SOP) is based on the understanding of influenza features, experience from prior respiratory epidemics (such as SARS), specialist consensus, and a safety-first attitude. In order to properly undertake monitoring and interventions in patients with and without influenza sickness during an epidemic, ensure that suitable resources are accessible and appropriate protocols are implemented.(3)Service attitude : a hospital is a platform where families go to get their health problems fixed and receive treatment. Due to their trauma, the patients are already in a condition of anguish and worry. The patients want to be treated with respect, cared for, and reassured. They require a promise of hope that their condition will improve as a result of treatment at the aforementioned facility. They must receive a favourable attitude from the hospital’s healthcare specialists in order to find consolation. Any profession benefits from having a positive attitude since it provides it an edge. However, in the healthcare field, attitude is extremely important, with a positive attitude being a requirement. Yes, when in the hospital, all healthcare staff, from the most senior surgeons and physicians to the most junior ward boy, must maintain a happy demeanour and a caring demeanour. This is due to the fact that the attitude of healthcare personnel in a hospital has an impact on the hospital’s relationship with its patients. Patient relationship management is essential for any hospital’s performance, as delighted patients result in increased referrals and repeat business. Patient happiness, on the other hand, is more dependent on the attitude of healthcare workers, which is what healthcare HR management focuses on in order to achieve hospital efficiency. Professional healthcare consulting organisations provide positive attitude training to hospital workers in order to assist them maintain a friendly and caring attitude toward patients. This boosts income and improves the hospital’s reputation by increasing patient happiness and loyalty. Having a superb customer service attitude entails being aware of client expectations, going above and beyond, and acting as a customer supporter. Expressing helpfulness, sincere passion, and respect has an effect on customer behaviour, converting uninterested customers to loyal ones. The administration’s attitude plays a vital role in the process of delivering medical services. A multitude of factors impact service attitude, including patience in answering queries, prevarication in responding, prejudice in service, and efficiency in achieving findings.(4)Medical expenses : medical expenditures incurred during the provision of medical services are crucial and must be within the patients’ acceptable financial reach. Medication costs, medical examination charges, fee transparency, prescription prices, hospital bed costs, expenditure correspondence, charge precision, and food costs are all encompassed in the context of healthcare expenses. The participants in our full medical insurance plan (FMIP) and the supplementary medical insurance plan (SMIP) have lately noticed that their donations have increased in order to avoid a predicted increase in insurance premiums beginning in January 1998. Apart from paying the higher payments, the participants can take steps to help keep future premium increases to a minimum. In today’s competitive medical-care industry, medical product and service consumers have a variety of options when it comes to medical spending. A group insurance plan’s participants create a risk community, and in such a community, each individual’s consumption patterns influence the overall plan’s performance and thus directly affect the amount of premiums paid to the insurer. As a result, we would want to encourage all members of our medical insurance plan to use the same caution and discipline while incurring medical expenses as they would when making a large purchase or repairing a car. In such instances, one would undoubtedly take the time to shop around for the best deal before spending the money. The same is true for medical care, where a customer can learn about his or her options, get cost estimates, and/or “shop around” for the best value for money before making a decision. While it is true that medical treatment, more than other products/services, incorporates nonquantifiable factors such as trust, it is nevertheless crucial to be aware that we have rights and options as patients. It is also critical to send a message to medical providers that their charges and rates will be scrutinised. The mindset that “the insurer pays regardless” is a certain way to boost premiums. As a result, it is critical that we take responsibility for our collective medical insurance plan and exercise extreme caution when it comes to medical spending.

Assume that the set of hospitals is and be a set of criteria for assessing the quality of medical services specified by a weight vector . The following are the various steps involved in developing a novel scheme for evaluating the quality of medical services on the basis of suggested operators: Step 1: the specialist matrices of IHFNs is enclosed in Table 1 Step 2: Table 2 evaluates the normalized decision matrices after normalisation Step 5(a): employed IHFAWG operator to integrate aggregated data enclosed in Table 3 as follows: Step 5(b): employed IHFAOWG operator to integrate aggregated data enclosed in Tables 4–6 Arranged row wise normalized matrix Step 5(c): employed IHFAHWG operator to integrate aggregated data enclosed in Tables 7–10 Step 6: observing the score function in Definition 10, the score values of are enclosed in Table 11: Step 7: under all the suggested Acz-Aln operators, has the largest score value; therefore, is our finest choice in terms of giving attributes.

7. Comparison Analysis

To show the applicability and appropriateness of the established operators-based methodology, we compared the approach based on the suggested operator in accordance with existing decision assistance approaches to validate the advantages and stability of the intuitionistic hesitant Acz-Aln Agops.

Peng et al. [46] evolved novel intuitionistic hesitant fuzzy weighted Agops to sort out the best alternative. Table 12 gives the comparison findings and shows that the IHFWG operator is a special instance of our developed IHFAWG operator, and it acquires when and .

As a nutshell, our suggested solutions are expected to become more extensive and flexible than a few existing strategies for addressing IHF MADM problems. The collected specialist data [46] are listed in Table 13:

Comparative studies with collected specialist data by [22] is enclosed in Table 14 as follows:

7.1. Advantages

The benefits are summarised as follows:(i)A multicriteria framework with a different approach to generating IF numbers is the IHF Acz-Aln method.(ii)By using the inverse sorting algorithm, the IHF Acz-Aln methodology standardises the home matrix elements, which permits I retention of the placement of normalized values on the measuring scale and the absence of domain shift or a distortion of the source data.(iii)The display of expert preferences is substantially facilitated by the IHF Acz-Aln algorithm, which is based on the ranking of criteria based on IHF values. Also, this fixes the issue with some multicriteria techniques’ limited range for predefined scales for comparing criteria.(iv)The suggested mathematical model serves two purposes. It can be used to define the weighting factors for attributes and alternatives as well as to prioritise.(v)Both individual and group decision making can be done using the proposed multicriteria framework.

8. Conclusion

Every day, we work with complex and cutting-edge data. We created approaches and tools for this kind of data in order to operate more efficiently and compute thorough information. The cost of condensing a large volume of data into a single value is a fundamental cost of aggregation. The IHFS was developed as a very effective combination of an IFS and HFS for scenarios where each item has a range of possible values determined by MD and non-MD.

We go into further detail about these strategies’ benefits as follows:(i)First, it discusses the implementation of the IHFAWG, IHFAOWG, and IHFAHWG operators, which are capable of capturing the interrelationships between all attributes and highlighting possible factors.(ii)Second, it discusses various characteristics of the IHFAWG, IHFAOWG, and IHFAHWG operators and also investigated some particular cases of the abovementioned operators and discussed their relationships between those operators in more detail.(iii)Third, it develops a unique method for evaluating the quality of medical services via the use of a criterion framework and a scheme. We use this novel methodology to assess four hospitals in order to show the method’s availability and conduct a comparison study to establish the method’s efficacy and superiority.(iv)The finding is that our strategy has a lot of benefits and trustworthy in IHF data DM. In other words, we may have easily described fuzzy information and make the information aggregation method more transparent than certain existing systems by supplying a parameter.(v)The existing Agops [46] do not make data aggregate more versatile. As a consequence, our suggested aggregation operations in IHF data DM are more comprehensive and reliable.(vi)The concept of Acz-Aln Agops may be extended to other fuzzy environments for assessing the quality of medical services in the future. Additionally, group decision making [47, 48] might be explored to strengthen the assessment result’s robustness.(vii)In our next work, we will investigate the theoretical foundations of IHFS’ Acz-Aln operations utilising cutting-edge decision-making techniques including TOPSIS, VIKOR, TODAM, GRA, and EDAS. We will also discuss how these methods are applied in a variety of fields, such as soft computing, robotics, horticulture, intelligent systems, social sciences, finance, and human resource management.
