Interval-valued intuitionistic hesitant fuzzy Choquet integral based TOPSIS method for multi-criteria group decision making
Deepa Joshi,Sanjay Kumar +1 more
TL;DR: The main purpose of this paper is to define the Choquet integral operator for interval-valued intuitionistic hesitant fuzzy sets (IVIHFS) and to extend the technique for order preference by similarity to ideal solution (TOPSIS) method using Choquet Integral operator in interval- valued intuitionists hesitant fuzzy environment.
Journal ArticleDOI
Intuitionistic fuzzy entropy and distance measure based TOPSIS method for multi-criteria decision making
Deepa Joshi,Sanjay Kumar +1 more
TL;DR: An intuitionistic fuzzy TOPSIS method for multi-criteria decision making (MCDM) problem to rank the alternatives is proposed based on distance measure and intuitionistically fuzzy entropy and it is observed that if the portfolios are constructed using the ranking obtained with proposed method, the return is increased with slight increment in risk.
Journal ArticleDOI
Fuzzy time series forecasting method based on hesitant fuzzy sets
Kamlesh Bisht,Sanjay Kumar +1 more
TL;DR: The proposed method addresses the problem of establishing a common membership grade for the situation when multiple fuzzification methods are available to fuzzify time series data.
Journal ArticleDOI
Intuitionistic fuzzy sets based method for fuzzy time series forecasting
TL;DR: A hybrid method of forecasting based on fuzzy time series and intuitionistic fuzzy sets is proposed that uses the degree of nondeterminacy to establish fuzzy logical relations on time series data.
Journal ArticleDOI
Intuitionistic Fuzzy Time Series: An Approach for Handling Nondeterminism in Time Series Forecasting
TL;DR: The notion of intuitionistic fuzzy time series to handle the nondeterminism in time series forecasting is given and an intuitionistic-fuzzy-set-based fuzzy timeseries forecasting model is also proposed.
