Multi-objective fixed-charge transportation problem using rough programming
Sudipta Midya,Sankar Kumar Roy +1 more
TL;DR: This paper analyses the multi-objective fixed-charge transportation problem (MOFCTP) using rough programming, and fuzzy programming method and linear weighted-sum method are used to obtain Pareto-optimal solution from deterministic MOF CTP.
Journal ArticleDOI
Impacts of green and preservation technology investments on a sustainable EPQ model during COVID-19 pandemic
TL;DR: In this paper , a multi-objective sustainable economic production quantity model is proposed with partially back-ordering shortages, in which the effects of sustainability are investigated to handle the demand fluctuation throughout the current pandemic, emergency level dependent demand rate is assumed.
Journal ArticleDOI
Multiobjective Transportation Problem Using Fuzzy Decision Variable Through Multi-Choice Programming
Gurupada Maity,Sankar Kumar Roy +1 more
TL;DR: A new formulation of mathematical model of MOFTP with fuzzy goal of each objective function is enlisted and the solution technique of the formulated model is described through multi-choice goal programming approach.
Journal ArticleDOI
Bi-level Programming for Stackelberg Game with Intuitionistic Fuzzy Number: a Ranking Approach
TL;DR: In this paper, intuitionistic fuzziness is characterized by a normal generalized triangular intuitionistic fuzzy number, and a defuzzification method is introduced based on the proportional probability density function associated with the corresponding membership function, as well as the complement of non-membership function.
Journal ArticleDOI
Soft Matrix Game: A Hesitant Fuzzy MCDM Approach
Jishu Jana,Sankar Kumar Roy +1 more
TL;DR: In this paper, a soft set theory has emerged recently as a new mathematical tool to handle uncertainty, where decision makers are not sure about the decision-making criteria, where soft sets theory provides an i...
