Abstract
1 | Introduction
In this paper we continue the research concerned with quantitative-information analysis of the
complex uncertainty and its use for modelling of more precise decisions with minimal decision risks
from the point of view of systems approach. We continue the construction of new generalizations of
OWA-type operators in fuzzy-probabilistic uncertainty [13], [14], which condense both characteristics
of incomplete information - an uncertainty measure and an imprecision variable in the scalar ranking
values of possible alternatives in the decision-making system. In the Part I of this work the definition
of the OWA operator ([15]-[17], [25]-[30], [34]-[36] and others) and some of its extensions–POWA
and FPOWA operators were presented. In this work our focus is directed to the construction of new
generalizations of the FPOWA operator described in the Section 1 of Part I (Definition 5).

The Ordered Weighted Averaging (OWA) operator was introduced by Yager [34] to provide a method for aggregating
inputs that lie between the max and min operators. In this article we continue to present some extensions of OWA-type
aggregation operators. Several variants of the generalizations of the fuzzy-probabilistic OWA operator-FPOWA
(introduced by Merigo [13], [14]) are presented in the environment of fuzzy uncertainty, where different monotone
measures (fuzzy measure) are used as uncertainty measures. The considered monotone measures are: possibility measure,
Sugeno 
λ additive measure, monotone measure associated with Belief Structure and Choquet capacity of order two.
New aggregation operators are introduced: AsFPOWA and SA-AsFPOWA. Some properties of new aggregation
operators and their information measures are proved. Concrete faces of new operators are presented with respect to
different monotone measures and mean operators. Concrete operators are induced by the Monotone Expectation
(Choquet integral) or Fuzzy Expected Value (Sugeno Integral) and the Associated Probability Class (APC) of a monotone
measure. New aggregation operators belong to the Information Structure I6 (see Part I, Section 3). For the illustration
of new constructions of AsFPOWA and SA-AsFPOWA operators an example of a fuzzy decision-making problem
regarding the political management with possibility uncertainty is considered. Several aggregation operators (“classic”
and new operators) are used for the comparing of the results of decision making.
Keywords: Mean aggregation operators, Fuzzy aggregations, Fuzzy measure, Fuzzy numbers, Fuzzy decision making.

In Section 2 new generalizations of the FPOWA operator are presented with respect to different
monotone measures (instead of the probability measure) and different mean operators. New versions
of the FPOWA operator are defined: AsFPOWA operators are induced by the Monotone Expectation
(ME) ([1], [2], [5], [10], [11], [20]-[23] and others) and SA-AsFPOWA operators are induced by the Fuzzy
Expected Value (FEV) ([3], [5], [11], [12], [18], [19], [21], [23], [24] and others). All generalizations are
constructed with respect to different monotone measures ([1]-[12], [18]-[24], [31]-[33] and others). Some
properties of new operators and their information measures [13], [14] are proved. For the illustration of
the applicability of the new generalizations of the FPOWA operator an example of the fuzzy decision-
making problem regarding political management is considered (Section 3), where we study a country
that is planning its fiscal policy for the next year analogously to the example considered by Merigo [14].
But we use the possibility distribution (possibility uncertainty) on the states of nature of decision-making
system instead of probability distribution (probability uncertainty) as considered in [14]. We think our
approach is more natural and applicable then the case presented in [14]. In this example several
aggregation operators are used for the comparing of the results in decision making:
 SEV (Shapely Expected Value) operator, introduced be Yager [29].
 A new operator SEV-FOWA as a weighted combination of SEV and FOWA operators.
 New operators – AsFPOWAmin, AsFPOWAmean, AsFPOWAmax, SA-AsFPOWAmin, SA-AsFPOWAmean
and Sa-AsFPOWAmax operators introduced in Section 2. The resulting table (see Table 8) is presented for
ordering of the policies. The values of Orness parameter are calculated for all presented aggregation operators.
2| Associated Probabilities’ Aggregations in the FPOWA Operator
In this section we construct new aggregations in the FPOWA operator (Definition 5, Part I) by
monotone measure’s associated probabilities (Definition 3, Part II [37]) when the imprecision variable
is presented by the fuzzy triangular numbers, FTNs, (Definition 2, Part I). So, we consider the
Information Structure I6 (Definition 7, Part I).
Let on the states of nature of General Decision-Making System (Definition 7, Part I) be given some
monotone measure as a uncertainty measure of incomplete information and on defined some payoffs
(utilities and so on) which are presented by triangular fuzzy numbers as expert reflections on possible
alternatives. i.e., for every alternative and for every state of nature there exists- positive triangular fuzzy
number as some payoff. So, vector is imprecision values of expert reflections on states of nature with
respect to alternatives.
Using the arithmetic operations on the triangular fuzzy numbers [6], [8], presented in Section 1, Part I,
we may define new aggregations in the FPOWA operator with respect to monotone measures’
associated probabilities.

Analogously we may construct the face of the AsFPOWAmin:
Analogously to Section 3, Part II [37] (Eqs. (38)-(39)) we may construct AsFPOWAmin and
AsFPOWAmax operators induced by the belief structure’s associated monotone measure (omitted
here). We also may define some other combinations of different monotone measures and averaging
operator M . So, there exist many cases of Information Structures on the level I6 for the constructions
of the AsFPOWA operator. For example - AsFPOWAmeanα with respect to the belief structure:
Note the information measures of the AsFPOWA operator - Orness, Entropy, Div and Bal ([13], [14],
[26] and others) are defined analogously to Subsection 3.3, Part II [37] (omitted here). We may add the
proposition concerning the dual monotone measures *
g and *
g [1], [20], [23] which is general for the
AsPOWA (see definition 7, Part II [37]) and AsFPOWA operators.

3| Example
Analogously to [14] we analyze an illustrative example on the use of new AsFPOWA and SA-AsFPOWA
operators in a fuzzy decision-making problem regarding political management. We study a country that is
planning its fiscal policy for the next year.
Assume that government of a country has to decide on the type of optimal fiscal policy for the next year.
They consider five alternatives:
 d1: “Development a strong expansive fiscal policy”.
 d2: “Development an expansive fiscal policy”.
 d3: “Do not make any changes in the fiscal policy”.
 d4: “Development of a contractive fiscal policy”.
 d5: “Development a strong contractive fiscal policy”.
In order to analyze these fiscal policies, the government has brought together a group of experts. This
group considers that the key factors are the economic situations of the world (external) and country
(internal) economy for the next period. They consider 3 possible states of nature that in whole could occur
in the future.
 s1: “Bad economic situation”.
 s2: “Regular economic situation”.
 s3: “Good economic situation”.
As a result, the group of experts gives us their opinions and results. The results depending on the state of
nature i
s and alternative k
d that the government selects are presented in the Table 1:
Table 1. Expert’s valuations in TFNs.
Following the expert’s knowledge on the world economy for the next period, experts decided that the
objective weights (as an external factor) of states of nature must be
 

W 0,5;0,3;0,2 , while for the
economy of the country for the next period the occurrence of presented states of nature is defined by some
possibilities (as an internal factor). So, there exist some possibilities (internal levels), as an uncertainty
measure, of the occurrence of states of nature in the country. This decision-making model (Information
Structure I6) is more detailed than the model (Information Structure I4) presented in [14]. In another
words in decision model, we cannot define the objective probabilities 
i i
p P(s ) for the future events, but
we can define subjective possibilities 
i i
π Pos(s ) based on the experts’ knowledge ([4], [8], [20] and Section
2, Part II [37]). Based on some fuzzy terms of internal factor – country economy experts define the
possibility levels of states of nature:

We also calculated values of the Orness parameter of the aggregation operators presented in Table 9.
Table 9. Orness values.
Following Table 9 we see that for the nearer of SA-AsFPOWA operators is to on or, the closer its
measure is to one, while AsFPOWAmin operator is to on and, the closer is to zero. Calculations of other
information measures are omitted here. More on these measures of new aggregation operators we will
present in our future papers.
4| Conclusion
New generalizations of the FPOWA operator were presented with respect to monotone measure’s
associated probability class and induced by the Choquet and Sugeno integrals (finite cases). There exist
many combinatorial variants to construct faces or expressions of generalized operators: AsFPOWA and
SA-AsFPOWA for concrete mean operators (Mean, Max, Min and so on) and concrete monotone
measures (Choquet capacity of order two, monotone measure associated with belief structure, possibility
measure and Sugeno 
λ additive measure). Some properties of new operators and their information
measures (Orness, Enropy, Divergence and Balance) are proved. But only some variants
(AsFPOWAmax, AsFPOWAmin and others) are presented, the list of which may be longer than it is
presented in the paper. So, other presentations of new operators and properties of information measures
will be considered in our future research. An example was constructed for the illustration of the
properties of generalized operators in the problems of political management.

New view of fuzzy aggregations. Part III: extensions of the FPOWA operator in the problem of political management

Corresponding Author: gia.sirbiladze@tsu.ge http://dx.doi.org/10.22105/jfea.2021.275097.1082 E-ISSN: 2717-3453 | P-ISSN: 2783-1442 | Abstract 1 | Introduction In this paper we continue the research concerned with quantitative-information analysis of the complex uncertainty and its use for modelling of more precise decisions with minimal decision risks from the point of view of systems approach. We continue the construction of new generalizations of OWA-type operators in fuzzy-probabilistic uncertainty [13], [14], which condense both characteristics of incomplete information - an uncertainty measure and an imprecision variable in the scalar ranking values of possible alternatives in the decision-making system. In the Part I of this work the definition of the OWA operator ([15]-[17], [25]-[30], [34]-[36] and others) and some of its extensions–POWA and FPOWA operators were presented. In this work our focus is directed to the construction of new generalizations of the FPOWA operator described in the Section 1 of Part I (Definition 5).

Journal of fuzzy extension and application, 2 (4), 321-333. Accept: 27/05/2021 Revised: 09/04/2021 Reviewed: 13/04/2021 Received: 25/02/2021 The Ordered Weighted Averaging (OWA) operator was introduced by Yager [34] to provide a method for aggregating inputs that lie between the max and min operators. In this article we continue to present some extensions of OWA-type aggregation operators. Several variants of the generalizations of the fuzzy-probabilistic OWA operator-FPOWA (introduced by Merigo [13], [14]) are presented in the environment of fuzzy uncertainty, where different monotone measures (fuzzy measure) are used as uncertainty measures. The considered monotone measures are: possibility measure, Sugeno  λ additive measure, monotone measure associated with Belief Structure and Choquet capacity of order two. New aggregation operators are introduced: AsFPOWA and SA-AsFPOWA. Some properties of new aggregation operators and their information measures are proved. Concrete faces of new operators are presented with respect to different monotone measures and mean operators. Concrete operators are induced by the Monotone Expectation (Choquet integral) or Fuzzy Expected Value (Sugeno Integral) and the Associated Probability Class (APC) of a monotone measure. New aggregation operators belong to the Information Structure I6 (see Part I, Section 3). For the illustration of new constructions of AsFPOWA and SA-AsFPOWA operators an example of a fuzzy decision-making problem regarding the political management with possibility uncertainty is considered. Several aggregation operators (“classic” and new operators) are used for the comparing of the results of decision making.

  • 2. 322 Sirbiladze|J. Fuzzy. Ext. Appl. 2(4) (2021) 321-333 In Section 2 new generalizations of the FPOWA operator are presented with respect to different monotone measures (instead of the probability measure) and different mean operators. New versions of the FPOWA operator are defined: AsFPOWA operators are induced by the Monotone Expectation (ME) ([1], [2], [5], [10], [11], [20]-[23] and others) and SA-AsFPOWA operators are induced by the Fuzzy Expected Value (FEV) ([3], [5], [11], [12], [18], [19], [21], [23], [24] and others). All generalizations are constructed with respect to different monotone measures ([1]-[12], [18]-[24], [31]-[33] and others). Some properties of new operators and their information measures [13], [14] are proved. For the illustration of the applicability of the new generalizations of the FPOWA operator an example of the fuzzy decision- making problem regarding political management is considered (Section 3), where we study a country that is planning its fiscal policy for the next year analogously to the example considered by Merigo [14]. But we use the possibility distribution (possibility uncertainty) on the states of nature of decision-making system instead of probability distribution (probability uncertainty) as considered in [14]. We think our approach is more natural and applicable then the case presented in [14]. In this example several aggregation operators are used for the comparing of the results in decision making:  SEV (Shapely Expected Value) operator, introduced be Yager [29].  A new operator SEV-FOWA as a weighted combination of SEV and FOWA operators.  New operators – AsFPOWAmin, AsFPOWAmean, AsFPOWAmax, SA-AsFPOWAmin, SA-AsFPOWAmean and Sa-AsFPOWAmax operators introduced in Section 2. The resulting table (see Table 8) is presented for ordering of the policies. The values of Orness parameter are calculated for all presented aggregation operators. 2| Associated Probabilities’ Aggregations in the FPOWA Operator In this section we construct new aggregations in the FPOWA operator (Definition 5, Part I) by monotone measure’s associated probabilities (Definition 3, Part II [37]) when the imprecision variable is presented by the fuzzy triangular numbers, FTNs, (Definition 2, Part I). So, we consider the Information Structure I6 (Definition 7, Part I). Let on the states of nature of General Decision-Making System (Definition 7, Part I) be given some monotone measure as a uncertainty measure of incomplete information and on defined some payoffs (utilities and so on) which are presented by triangular fuzzy numbers as expert reflections on possible alternatives. i.e., for every alternative and for every state of nature there exists- positive triangular fuzzy number as some payoff. So, vector is imprecision values of expert reflections on states of nature with respect to alternatives. Using the arithmetic operations on the triangular fuzzy numbers [6], [8], presented in Section 1, Part I, we may define new aggregations in the FPOWA operator with respect to monotone measures’ associated probabilities. 2.1| AsFPOWA Operators Induced by the ME Let       k M :Ψ Ψ k m! be some deterministic mean aggregation function with symmetricity, boundedness, monotonicity and idempotency properties ([29] and Section 1, Part I), where  Ψ denotes the set of all positive TNF.

(38)-(39)) we may construct AsFPOWAmin and AsFPOWAmax operators induced by the belief structure’s associated monotone measure (omitted here). We also may define some other combinations of different monotone measures and averaging operator M . So, there exist many cases of Information Structures on the level I6 for the constructions of the AsFPOWA operator. For example - AsFPOWAmeanα with respect to the belief structure: Note the information measures of the AsFPOWA operator - Orness, Entropy, Div and Bal ([13], [14], [26] and others) are defined analogously to Subsection 3.3, Part II [37] (omitted here). We may add the proposition concerning the dual monotone measures * g and * g [1], [20], [23] which is general for the AsPOWA (see definition 7, Part II [37]) and AsFPOWA operators. Proposition 1.

  • 7. 327 New view of fuzzy aggregations. Part III: extensions of the FPOWA operator in the problem of political management 3| Example Analogously to [14] we analyze an illustrative example on the use of new AsFPOWA and SA-AsFPOWA operators in a fuzzy decision-making problem regarding political management. We study a country that is planning its fiscal policy for the next year. Assume that government of a country has to decide on the type of optimal fiscal policy for the next year. They consider five alternatives:  d1: “Development a strong expansive fiscal policy”.  d2: “Development an expansive fiscal policy”.  d3: “Do not make any changes in the fiscal policy”.  d4: “Development of a contractive fiscal policy”.  d5: “Development a strong contractive fiscal policy”. In order to analyze these fiscal policies, the government has brought together a group of experts. This group considers that the key factors are the economic situations of the world (external) and country (internal) economy for the next period. They consider 3 possible states of nature that in whole could occur in the future.  s1: “Bad economic situation”.  s2: “Regular economic situation”.  s3: “Good economic situation”. As a result, the group of experts gives us their opinions and results. The results depending on the state of nature i s and alternative k d that the government selects are presented in the Table 1: Table 1. Expert’s valuations in TFNs. Following the expert’s knowledge on the world economy for the next period, experts decided that the objective weights (as an external factor) of states of nature must be              W 0,5;0,3;0,2 , while for the economy of the country for the next period the occurrence of presented states of nature is defined by some possibilities (as an internal factor). So, there exist some possibilities (internal levels), as an uncertainty measure, of the occurrence of states of nature in the country. This decision-making model (Information Structure I6) is more detailed than the model (Information Structure I4) presented in [14]. In another words in decision model, we cannot define the objective probabilities  i i p P(s ) for the future events, but we can define subjective possibilities  i i π Pos(s ) based on the experts’ knowledge ([4], [8], [20] and Section 2, Part II [37]). Based on some fuzzy terms of internal factor – country economy experts define the possibility levels of states of nature: S D 1 s 2 s 3 s 1 d (60,70,80) (40,50,60) (50,60,70) 2 d (30,40,50) (60,70,80) (70,80,90) 3 d (50,60,70) (50,60,70) (60,70,80) 4 d (70,80,90) (40,50,60) (40,50,60) 5 d (60,70,80) (70,80,90) (50,60,70)

  • 12. 332 Sirbiladze|J. Fuzzy. Ext. Appl. 2(4) (2021) 321-333 We also calculated values of the Orness parameter of the aggregation operators presented in Table 9. Table 9. Orness values. Following Table 9 we see that for the nearer of SA-AsFPOWA operators is to on or, the closer its measure is to one, while AsFPOWAmin operator is to on and, the closer is to zero. Calculations of other information measures are omitted here. More on these measures of new aggregation operators we will present in our future papers. 4| Conclusion New generalizations of the FPOWA operator were presented with respect to monotone measure’s associated probability class and induced by the Choquet and Sugeno integrals (finite cases). There exist many combinatorial variants to construct faces or expressions of generalized operators: AsFPOWA and SA-AsFPOWA for concrete mean operators (Mean, Max, Min and so on) and concrete monotone measures (Choquet capacity of order two, monotone measure associated with belief structure, possibility measure and Sugeno  λ additive measure). Some properties of new operators and their information measures (Orness, Enropy, Divergence and Balance) are proved. But only some variants (AsFPOWAmax, AsFPOWAmin and others) are presented, the list of which may be longer than it is presented in the paper. So, other presentations of new operators and properties of information measures will be considered in our future research. An example was constructed for the illustration of the properties of generalized operators in the problems of political management.
