1. Introduction
MADM is the fundamental significance of the decision-making (DM) science whose goal is to perceive the best option(s) from the set of likely ones. In genuine DM, an individual needs to assess the given alternatives by various classes, such as single, span, and so forth, of assessment purposes. Be that as it may, in different capricious conditions, it is generally trying for the individual to deliver their decisions as a fresh number. For this, the principle of intuitionistic fuzzy set (IFS), initiated by Atanassov [
1], is used, by putting the falsity grade (FG) in the principle of fuzzy set [
2]. The rule of IFS is extensively modified compared to the rule of FS, such that the sum of the duplet cannot exceed the unit interval. When the proposal of IFS was developed, it gained broad attention, and certain researchers have employed it in separate regions. For example, Liu et al. [
3] initiated the hybrid approach based on variable weight under IFSs, Garg and Rani [
4] elaborated the certain types of measures by using a right-angle triangle under the IFSs, and Xue and Deng [
5] proposed the granular uncertainty measures based on IFSs. Thao [
6] discovered certain entropy and divergent measures based on IFSs, Rahman et al. [
7] explored the generalized Einstein operators under the IFSs, Kar et al. [
8] presented the trapezoidal intuitionistic type-2 fuzzy setting and their application in decision-making, Bhattacharyee et al. [
9] utilized the optimization theory in the field of IFSs, and Ejegwa and Onyeke [
10] elaborated the statistical review of certain types of measures by using IFSs.
In some situations, the theory of IFS has failed. For instance, when a person obtains
for the truth grade (TG) and
for the FG, the theory of IFS is not able to cope with it, i.e.,
, and therefore the rule of IFS has been neglected. Similarly, there are certain problems in genuine life concerns where the principle of IFS has been neglected. For this, Yager [
11] improved the rule of IFS to initiate the principle of Pythagorean FS (PFS), with a rule stating that the sum of the squares of the duplet cannot exceed [0, 1]. Moreover, Garg [
12] comprehensively reviewed the various approaches for solving the decision-making approach under the PFS environment. Bakioglu and Atahan [
13] introduced the TOPSIS, AHP, and VIKOR methods for PFSs, Sarkar and Biswas [
14] introduced the AHP-TOPSIS method for PFSs, Naeem et al. [
15] initiated the Pythagorean m-polar fuzzy sets and their applications, Deb and Roy [
16] developed the network information by using software under PFSs, Zulqarnain et al. [
17] elaborated the aggregation operators for PFSs, and Satirad et al. [
18] presented the UP-algebra in the environment of PFSs.
Researchers have employed the principle of PFS in distinct regions based on their powerful structure. However, in various circumstances, the principle of PFS is neglected, for example, if an individual provided information in the shape of
for the truth grade (TG) and FG, such that
, then the rule of PFS has been neglected. Similarly, as mentioned above, there are certain problems in genuine life concerns where the principle of PFS has been neglected. Yager [
19] improved the rule of PFS to initiate the principle of q-rung orthopair FS (q-ROFS), with a rule that states that the sum of the q-powers of the duplet cannot exceed [0, 1]. IFS and PFS are special cases of the q-ROFS used to effectively determine the consistency of the initiated operators. When the proposal of q-ROFS was developed, it gained broad attention from various researchers, who have employed it in separate regions. For example, Garg [
20] initiated possibility degree measures for using q-ROFSs, Liu et al. [
21] presented the bidirectional projection under q-ROFSs, Garg [
22] proposed the exponential operations under the q-ROFSs, Khan et al. [
23] developed the knowledge measures under q-ROFSs, and Jan et al. [
24] introduced the generalized dice measures for q-ROFSs.
In everyday life, vulnerability and ambiguity, which are available in the information, happen simultaneously with changes to the stage (periodicity) of the information. Subsequently, the current speculations are inadequate to consider this data, and consequently, there is a data misfortune during the cycle. To defeat it, the theory of complex IFS (CIFS), initiated by Alkouri and Salleh [
25], is used, by putting the FG in the principle of complex FS (CFS) [
26]. The rule of CIFS is extensively modified compared to the rule of CFS, such that the sum of the real and unreal parts of the duplet cannot exceed [0, 1]. The proposal of CIFS has received attention from various researchers, who have employed it in separate regions. For example, Garg and Rani [
27] explored the aggregation operators for complex interval valued IFSs, Rani and Garg [
28] proposed certain measures for CIFSs, Garg and Rani [
29] introduced the robust measures for CIFSs, and Garg and Rani [
30] initiated the aggregation operators for CIFSs. Researchers have employed the principle of CIFSs in distinct regions based on its powerful structure. However, in various circumstances, the principle of CIFS is neglected, for example, if an individual provided information in the shape of
for the TG and FG, such that
, then the rule of CIFS has been neglected. There are also certain problems in genuine life concerns in which the principle of CIFS has been neglected. For this, Ullah et al. [
31] improved the rule of CIFS to initiate the principle of complex PFS (CPFS), with a rule that states that the sum of the squares of the real and unreal parts of the duplet cannot exceed [0, 1]. CIFS is a special case of the CPFS used to effectively determine the consistency of the initiated operators. CPFS gained broad attention from researchers, whohave employed it in separate regions.
The Cq-ROFSs was first evolved by Liu et al. [
32,
33], which is the speculation of CIFS and CPFS. In Cq-ROFSs, the amount of the q-th force of the genuine part (additionally for the imaginary part) of the participation and the q-th force of the genuine part (likewise for the imaginary part) of the non-enrollment is not multiple. The Cq-ROFSs can manage circumstances which cannot be managed by CIFS and CPFS. For instance, the trait esteem is
in the evaluation of the employee’s performance. Obviously,
. However, if
, then
. Consequently, we can utilize Cq-ROFSs to portray information that cannot be managed by CIFS and CPFS. In addition, CIFS and CPFS are for the most part extraordinary instances of the Cq-ROFSs. Some investigations have been carried out, and numerous researchers have used Cq-ROFSs in the environment of various areas. For example, Mahmood and Ali [
34] initiated the certain entropy and TOPSIS method for Cq-ROFSs, Ali and Mahmood [
35] initiated Maclaurin symmetric mean operators for Cq-ROFSs, and Mahmood and Ali [
36] explored the aggregation operators under Cq-ROFSs.
To find the relation between any number of attributes, the HM operator is one of the more broad, flexible, and dominant principles used to operate problematic and inconsistent information in actual life dilemmas, and certain researchers have implemented it in the environment of various areas. For example, Wu et al. [
37] initiated the HM operators for interval valued IFSs, Li et al. [
38] proposed the Dombi HM operators for IFSs, Wu et al. [
39] developed the Dombi HM operators for interval valued IFSs, Liang [
40] also initiated the HM operators for IFSs, Li et al. [
41] explored the HM operators for PFSs, and Wang et al. [
42] investigated the HM operators under the q-ROFSs. However, to date, no one has utilized the principle of HM operators in the environment of CIFS, CPFS, and Cq-ROFSs. Based on the above analysis, we develop certain operators based on Cq-ROFSs. The main aims and contributions of this paper are:

Certain researchers have utilized the MADM technique in the environment of distinct regions. Keeping the advantages of the MADM procedure, in this study, we utilized the HM operators under the Cq-ROFNs in decision making to determine the dominance and flexibility of the investigated operators. For this, we chose the family of alternatives and their attributes . Furthermore, we considered the weight vector, whose expressions are follows: under the rule . First, we developed the decision matrix (DM), whose items are in the shape of Cq-ROFNs, such that . To resolve the above troubles, we constructed an algorithm, the steps of which are discussed below:
Step 1: By using the Cq-ROFNs, we build up the DM.
Step 2: Keeping the Cq-ROFWHM operator, we aggregate the DM obtained in Step 1.
Step 3: By using the SV, we determine the SV of the aggregated values in Step 2.
Step 4: By using the SV, we rank all values and determine the best optimal value.
Unfamiliar interest in a current Pakistani organization basically follows the very guidelines as that for new pursuits. Any acquisition of offers by an unfamiliar financial backer would require such speculation to be enlisted with the State Bank of Pakistan in order to empower the qualification of an unfamiliar venture, such as that of another endeavor.
Putting resources into banks and investment companies is one of the least expensive business openings in Pakistan, with low speculation. A financial balance is opened and a modest quantity is stored in it. Resources are put into the account each month. Banks normally offer 10% to 12% yearly returns. A little research is necessary to select the bank that is best suited to the business. For this, we delineated a mathematical model, which is expressed below.
Example 3. An investment company wants to invest in a company to increase income; for this, we provide an actual example to illustrate the MADM process of the novel MADM method. Assume that there are four companies. In this investigation, we provide a guide to communicate the dependability and viability of the spearheaded approach. An endeavor needs to pick a provider, and there are four providers as applicants, . We inspect every provider from four viewpoints,, which are “creation cost”, “creation quality”, “provider’s administration execution”, and “hazard factor”. The weight vector of the qualities is given by. Then, at that point, the means of calculation to take care of the issues are given by the following steps.
Step 1: By using the Cq-ROFNs, we build up the DM, which is implemented in the form of

Additionally, by using the information in Example 3, the comparative analysis of the elaborated and certain prevailing ideas is discussed. For this, we chose the following prevailing ideas, such as: power aggregation operators based on CIFS, as developed by Rani and Garg [
43], the aggregation operators based on CIFS, initiated by Garg and Rani [
30], and Liu et al. [
32,
33] initiated the aggregation operators for complex q-rung orthopair fuzzy linguistic sets and complex q-rung orthopair fuzzy sets. To determine the supremacy and consistency of the initiated operators, the sensitive analysis is discussed in
Table 4.

30,
32,
33,
43] and our proposed strategy dependent on the Cq-ROFWHM operator. Although the positioning outcome dependent on the Cq-ROFWHM operator is somewhat different than the others, the best option is consistently
. Therefore, the strategy in this paper is viable and possible. The geometrical understanding of
Table 4 is shown in
Figure 1.
5. Advantages and Comparative Analysis
In this section, we direct a few correlations from a quantitative viewpoint. We used some leaving strategies to settle on a similar model and consider their last positioning outcomes. We compared our strategy and the technique proposed by Rani and Garg [
43], dependent on a power collection administrator that is dependent on CIFS, and the technique proposed by Garg and Rani [
30], dependent on an accumulation operator that is dependent on CIFS. The score capacities and positioning outcomes are displayed in
Table 4. Be that as it may, our technique depending on the Cq-ROFWHM operators was compared, and existing strategies are discussed about in an outline model (c-f). As a matter of first importance, every one of the techniques aside from our strategy depends on CIFS. As we referenced previously, CIFS is just a unique instance of Cq-ROLS (when q = 1). Alkouri and Salleh [
25] proposed the idea of CIFS. The idea of CPFS was proposed by Ullah et al. [
31], which is likewise an extraordinary instance of Cq-ROLS (when q = 2). Consequently, our technique is more effective than the various other strategies.
