1.   Introduction

To evaluate a lot of genuine life troubles, MADM is the most dominant and feasible procedure from the decision-making strategy to survive with intricate data in authentic life scenarios. Under the beneficial processes of MADM conception, a lot of people have employed it in the circumstance of diverse territories. But, to accomplish with more than two sorts of opinions, Zadeh ^[1] firstly invented such sort of idea which includes more than two sorts of opinions in the shape of truth grade (TG) is called fuzzy set (FS). A large number of scholars have modified the conception of FS were to present the intuitionistic FS (IFS) ^[2], soft set (SS) ^[3], N-SS ^[4], fuzzy N-SS ^[5,6], Hesitant N-SS ^[7], bipolar valued FS (BFS) ^[8] and bipolar SS (BSS) ^[9]. All these theories have their importance but IFS proves to be a valuable procedure to convey the awkward fuzzy knowledge because it has TG $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{if}}\left(\mathcal{b}\right) $ and falsity grade (FG) $ {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{if}}\left(\mathcal{b}\right) $, with $ 0\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{if}}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{if}}\left(\mathcal{b}\right)\le 1 $. Further, Yager ^[10] diagnosed another well-known conception of Pythagorean FS (PFS), with a valuable technique $ 0\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{pf}}^{2}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{pf}}^{2}\left(\mathcal{b}\right)\le 1 $. Some implementations have been invented by distinct peoples likewise, correlation coefficient ^[11], different sort of methods ^[12], Pythagorean m-polar FSs ^[13], TOPSIS methods ^[14], and Chebyshev measure ^[15] by using the PFSs.

The conception of FS was extended by Ramot et al. ^[16]. They initiated the technique of complex FS (CFS), signifying TG $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{cp}}\left(\mathcal{b}\right) = {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right){e}^{i2\pi \left({\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)\right)} $, with $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right), {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)\in \left[\mathrm{0, 1}\right] $. But in a lot of scenarios, they are unable to identify real-life dilemmas. In that spot, the complex IFS (CIFS), invented by Alkouri and Salleh ^[17]. CIFS includes the TG $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{cp}}\left(\mathcal{b}\right) = {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right){e}^{i2\pi \left({\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)\right)} $ and FG $ {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{cp}}\left(\mathcal{b}\right) = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right){e}^{i2\pi \left({\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)\right)} $, with $ 0\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{RT}}\left(\mathcal{b}\right)\le \mathrm{1, 0}\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT}}\left(\mathcal{b}\right)\le 1 $. Several modifications are illustrated here: for instance, CIF classes ^[18], CIF graph ^[19], CIF soft sets ^[20], CIF aggregation operators (AOs) ^[21], CIF quaternion number ^[22], CIF group ^[23], CIF algebraic structure ^[24]. Further, Ullah et al. ^[25] diagnosed the complex PFS (CPFS), which includes a new well-known strategy in the shape $ 0\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT}}^{2}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{RT}}^{2}\left(\mathcal{b}\right)\le \mathrm{1, 0}\le {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT}}^{2}\left(\mathcal{b}\right)+{\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT}}^{2}\left(\mathcal{b}\right)\le 1 $. A lot of applications have been employed by Akram and Naz ^[26], Akram and Sattar ^[27], Akram et al. ^[28], Ma et al. ^[29], Akram and Khan ^[30], and Garg ^[31].

IFSs, PFSs, CIFSs, and CPFSs have achieved a lot of well-wishes from the side of scholars under the very well-known techniques of all prevailing conceptions. The distinct sort of implementations are stated in the shape: geometric AOs for IFSs ^[32], Hamacher AOs for IFSs ^[33], frank power AOs for IFSs ^[34], Heronian AOs for IFSs ^[35], Harmonic AOs for IFSs ^[36], Bonferroni AOs for IFSs ^[37], Prioritized AOs for IFSs ^[38], Power AOs for IFSs ^[39], Maclaurin symmetric mean for IFSs ^[40], AOs for PFSs ^[41], Einstein AOs for PFSs ^[42], Hamacher AOs for PFSs ^[43], Choquet frank AOs for PFSs ^[44], Heronian AOs for IFSs ^[45], Bonferroni AOs for PFSs ^[46], Prioritized AOs for PFSs ^[47], Power AOs for IFSs ^[48], Maclaurin symmetric mean for PFSs ^[49]. Under the above circumstances, a decision-making strategy always includes a lot of major hurdles as:

1) How to demonstrate the data on the appropriate procedures to clarify the data.

2) How to calculate the distinct attribute objects and arrange the generally favorite quantity.

3) How to study the beneficial ideal from a lot of collections in the shape of alternatives.

Hence, the major contribution of the theme is to invent the beneficial decision-making strategy under CPFSs by using the AOs for CLs. The prevailing conceptions are the specific parts of the invented CPFSs under implementing the distinct sort techniques. In CPFS, the intellectual faced two sorts of theory in the shape of real and unreal terms, which can help to decision-maker for taking a beneficial decision. But the prevailing IFSs, PFSs have a grip on one aspect at a time due to their weak mathematical structure. The unreal terms have been completely missed in these two ideas and due to these issues, the decision-maker loses a lot of data during the decision-making procedure. The importance of the unreal term in CPFS is that if an expert wants to lunch the car enterprise based on the well-known considerations in the shape of its name of the car and production dates. Here, the name of the car shows the real part, and the production of the car date shows the unreal part. For managing with such sort of scenario, the technique of IFS and PFS has been unsuccessful. For this, we consider the well-known conception of CPFS to try to demonstrate the beneficial results. The key factors of the invented works are implemented in the shape:

1) To analyze some new operational laws based on CLs for CPF setting.

2) To demonstrate the concept of CCPFWA, CCPFOWA, CCPFWG, and CCPFOWG operators are invented.

3) Several significant features of the invented works are also diagnosed.

4) To investigate the beneficial optimal from a large number of alternatives, a MADM analysis is analyzed based on CPF data. A lot of examples are demonstrated based on invented works to evaluate the supremacy and ability of the initiated works.

5) To identify the sensitive analysis and merits of the invented works with the help of comparative analysis and they're graphical shown.

The sensitive analysis of the prevailing and proposed works is diagnosed in the shape of Table 1.

In Table 1, we easily get that the symbol " $ \surd $ " stated the operators were developed someone and the symbol $ \times $, stated the operators cannot be developed by anyone up to date. We know that the conception of CPFS is very well-known and interesting, but up to date, no one has employed it in the region of any sorts of operators to investigate the feasibility and consistency of the invented works. For more convenience, we illustrated Figure 1, which stated the invented works.

Lastly, the main characteristics of the CPFSs under a lot of points are illustrated in Table 2.

Likewise, a narrative MADM process in the viewpoint of these recommended operators is constructed in which rankings are characterized in conditions of CPFNs. The feasibility down with the prevalence of methodology is illustrated over a genuine-life mathematical statistic and verified by differing their results with many prevalent approaches.

This analysis is constructed in the shape: Section 2 includes some prevailing concepts of CPFSs and their related properties. Section 3 includes analyzing some new operational laws based on CLs for the CPF setting. Moreover, to demonstrate the closeness between finite numbers of alternatives, the conception of CCPFWA, CCPFOWA, CCPFWG, and CCPFOWG operators are invented. Several significant features of the invented works are also diagnosed. Section 4 investigates the beneficial optimal from a large number of alternatives, a MADM analysis is analyzed based on CPF data. A lot of examples are demonstrated based on invented works to evaluate the supremacy and ability of the initiated works. For massive convenience, the sensitivity analysis and merits of the identified works are also explored with the help of comparative analysis and they're graphically shown. The conclusion is referred to in Section 5.

2.   Preliminaries

For the convenience of the reader, here we reviewed the conception of CIFSs, initiated by Alkouri and Salleh ^[17].

Then some techniques are diagnosed here, if $ {\mathcal{S}}_{sv}\left({\mathcal{C}\mathfrak{f}}_{cp-1}\right) > {\mathcal{S}}_{sv}\left({\mathcal{C}\mathfrak{f}}_{cp-2}\right)⟹{\mathcal{C}\mathfrak{f}}_{cp-1} > {\mathcal{C}\mathfrak{f}}_{cp-2} $;

and if $ {\mathcal{S}}_{sv}\left({\mathcal{C}\mathfrak{f}}_{cp-1}\right) = {\mathcal{S}}_{sv}\left({\mathcal{C}\mathfrak{f}}_{cp-2}\right) $ then $ {\mathcal{H}}_{av}\left({\mathcal{C}\mathfrak{f}}_{cp-1}\right) > {\mathcal{H}}_{av}\left({\mathcal{C}\mathfrak{f}}_{cp-2}\right)⟹{\mathcal{C}\mathfrak{f}}_{cp-1} > {\mathcal{C}\mathfrak{f}}_{cp-2} $;

Moreover, if $ {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{RT-\mathfrak{j}}} = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}} = 0 $ in Eq (10), then we get CFSs, by putting "1" instead of "2", in Eq (10), then we get CIFSs.

This study includes demonstrating the closeness between a finite number of alternatives, the conception of CCPFWA, CCPFOWA, CCPFWG, and CCPFOWG operators are invented. Several significant features of the invented works are also diagnosed. In this all work, we used the CPFNs by $ {\mathcal{C}\mathfrak{f}}_{cp-\mathfrak{j}} = \left({\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{RT-\mathfrak{j}}}\left(\mathcal{b}\right){e}^{i2\pi \left({\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right)\right)}, {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{RT-\mathfrak{j}}}\left(\mathcal{b}\right){e}^{i2\pi \left({\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right)\right)}\right), \mathfrak{j} = \mathrm{1, 2}, \dots , \stackrel{⏞}{\mathcal{n}\mathfrak{t}} $, and $ {\Delta :}_{\mathfrak{j}} $ be the CL of $ {\mathcal{C}\mathfrak{f}}_{cp-\mathfrak{j}} $ with $ 0\le {\Delta :}_{\mathfrak{j}}\le 1 $.

2.3.1.   CCPFWA operator

Definition 9. The CCPFWA operator is diagnosed by:

Several specific cases are gotten after the implementation of distinct techniques, for instance, if $ {\Delta :}_{\mathfrak{j}} = 0 $ in Eq (19), then we get CPF weighted averaging operator. We got the theory of the CIF weighted averaging operator by changing the value of "2" in Eq (19) into "1". If $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = 0 $ in Eq (19), then we get PF weighted averaging operator. We got the theory of IF weighted averaging operator by changing the value of "2" with $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = 0 $, in Eq (19) into "1".

In Eq (20), we fix $ \stackrel{⏞}{\mathcal{n}\mathfrak{t}} = k $, because for $ \stackrel{⏞}{\mathcal{n}\mathfrak{t}} = 2 $, hold.

For $ \stackrel{⏞}{\mathcal{n}\mathfrak{t}} = k+1 $, we have gotten

Equation (20) holds for all possible values of $ \stackrel{⏞}{\mathcal{n}\mathfrak{t}} $.

If $ {\Delta :}_{\mathfrak{j}} = 0 $ in Eq (20), then we get CPF weighted averaging operator. We got the theory of the CIF weighted averaging operator by changing the value of "2" in Eq (20) into "1". If $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = 0 $ in Eq (20), then we get PF weighted averaging operator. We got the theory of IF weighted averaging operator by changing the value of "2" with $ {\mathcal{T}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = {\mathcal{F}}_{{\mathcal{C}\mathfrak{f}}_{IT-\mathfrak{j}}}\left(\mathcal{b}\right) = 0 $, in Eq (20) into "1".

Nowadays, a lot of vaccines have been found by different countries, but the Chines vaccine has gotten a lot of attention and several people have used it. Several important symptoms are diagnosed here, for instance, coughing, headache, loss of taste, sore throat, and muscle pain.

$ {\mathcal{C}\mathfrak{f}}_{al-3} $: Feeling extremely drained.

$ {\mathcal{C}\mathfrak{f}}_{al-4} $: Muscle or body throbs.

With four criteria in the shape of dangerous symptoms such as:

$ {\mathcal{C}\mathfrak{f}}_{at-1} $: Inconvenience relaxing.

$ {\mathcal{C}\mathfrak{f}}_{at-2} $: Steady agony or tension in your chest.

$ {\mathcal{C}\mathfrak{f}}_{at-3} $: Pale blue lips or face.

2.5.   Sensitivity analysis

Achievement without complication is very difficult due to ambiguity and rationality which is involved in genuine life dilemmas. MADM technique is one of the beneficial ways to determine our goal. The key technique of our works is to demonstrate the supremacy and effectiveness of the invented works. For this, several suggested works are discussed here: CLs for IFSs ^[50], CLs for PFSs ^[31], AOs for CIFSs ^[21], AOs for CPFSs ^[28], geometric AOs for IFSs ^[32], Hamacher AOs for IFSs ^[33], AOs for PFSs ^[41], Heronian AOs for IFSs ^[45], Bonferroni AOs for PFSs ^[46], and with several invented works are diagnosed in Table 12, under the consideration of data in Example 1. For more convenience, we illustrated Figure 6, which stated the invented works in Table 12.

For more convenience, we illustrated Figure 7, which stated the invented works in Table 13.

Under the data in Table 2 from ^[17], several analyses are diagnosed in Table 13.

Under the data in Table 5 from ^[27], several analyses are diagnosed in Table 14.

For more convenience, we illustrated Figure 8, which stated the invented works in Table 14.

After a long discussion, we have gotten the result that the invented works are massive feasible, and accurate to demonstrate the value of objects appropriately. Therefore, the invented works under the CPFSs are extensively reliable, and more consistent is compared to existing operators ^{[21,28,31,32,33,41,45,46,50]} and in future we will extend to compare with some new works which are discussed in ^{[42,43,44,47,48,49]}.

3.   Conclusions

Ambiguity and uncertainty have been involved in several genuine life dilemmas, MADM technique is the most influential part of the decision-making technique to handle inconsistent data which occurred in many scenarios. The major construction of this works is exemplified in the succeeding ways:

1) We analyzed some new operational laws based on CLs for the CPF setting.

2) We demonstrated the closeness between a finite number of alternatives, the conception of CCPFWA, CCPFOWA, CCPFWG, and CCPFOWG operators are invented.

3) Several significant features of the invented works are also diagnosed.

4) We investigated the beneficial optimal from a large number of alternatives, a MADM analysis is analyzed based on CPF data.

5) A lot of examples are demonstrated based on invented works to evaluate the supremacy and ability of the initiated works.

6) For massive convenience, the sensitivity analysis and merits of the identified works are also explored with the help of comparative analysis and they're graphical shown.

In the upcoming times, we will outspread the idea of complex q-rung orthopair FSs ^[51,52], complex spherical FSs ^[53,54], and Spherical fuzzy sets ^[55,56], etc. to advance the quality of the research works.
