Application of Choquet Integral-Fuzzy Measures for Aggregating Customers’ Satisfaction

open access: yesAdvances in Fuzzy Systems, 2021
Choquet integral is a type of aggregation operator that is commonly used to aggregate the interrelated information. Nowadays, this operator has been successfully embedded with fuzzy measures in solving various evaluation problems.

Hesitant fuzzy linguistic multicriteria decision-making method based on generalized prioritized aggregation operator. [PDF]

open access: yesScientificWorldJournal, 2014
Based on linguistic term sets and hesitant fuzzy sets, the concept of hesitant fuzzy linguistic sets was introduced. The focus of this paper is the multicriteria decision-making (MCDM) problems in which the criteria are in different priority levels and ...

Single machine scheduling problems with uncertain parameters and the OWA criterion [PDF]

open access: yes, 2014
In this paper a class of single machine scheduling problems is discussed. It is assumed that job parameters, such as processing times, due dates, or weights are uncertain and their values are specified in the form of a discrete scenario set.

Pythagorean fuzzy ordered weighted averaging aggregation operator and their application to multiple attribute group decision-making

open access: yes, 2020
The objective of the present work is twofold. First, Pythagorean fuzzy ordered weighted averaging (PFOWA) aggregation operator is introduced along with its desirable properties, namely commutatively, idempotency, boundedness and monotonicity.

Parametric Extension of the Most Preferred OWA Operator and Its Application in Search Engine's Rank

open access: yesJournal of Applied Mathematics, 2013
Most preferred ordered weighted average (MP-OWA) operator is a new kind of neat (dynamic weight) OWA operator in the aggregation operator families. It considers the preferences of all alternatives across the criteria and provides unique aggregation ...

A method for decision making with the OWA operator [PDF]

open access: yes, 2014
A new method for decision making that uses the ordered weighted averaging (OWA) operator in the aggregation of the information is presented. It is used a concept that it is known in the literature as the index of maximum and minimum level (IMAM).

Indicators for the characterization of discrete Choquet integrals [PDF]

open access: yes, 2014
Ordered weighted averaging (OWA) operators and their extensions are powerful tools used in numerous decision-making problems. This class of operator belongs to a more general family of aggregation operators, understood as discrete Choquet integrals ...

γ‐Agregation operators and some aspects of generalized aggregation problem

open access: yesMathematical Modelling and Analysis, 2010
We explore questions related to the aggregation operators and aggregation of fuzzy sets. No preliminary knowledge of the aggregation operators theory and of the fuzzy sets theory are required, because all necessary information is given in Section 2 ...
