Green Logistics Partner Selection Based on Pythagorean Hesitant Fuzzy Set and Multiobjective Optimization

Some aspects on hesitant fuzzy soft set

Research on Green Logistics Service Providers Selection Based on Intuitionistic Language Fuzzy Entropy

Based on a comprehensive consideration of features of the selection of green logistics service providers, the paper, proposes the criteria for evaluating providers of green logistics service by combining the traditional evaluation index system, and the criteria are determined as compatibility with the users, cost of service, quality of service, service ability and adaptation with environment. I...

Combinatorial optimization and Green Logistics

The purpose of this paper is to introduce the area of Green Logistics and to describe some of the problems that arise in this subject which can be formulated as combinatorial optimization problems. The paper particularly considers the topics of reverse logistics, waste management and vehicle routing and scheduling.

A Hesitant Fuzzy Set Theory Based Approach for Project Portfolio Selection with Interactions under Uncertainty

This paper proposes a new practical model for project portfolio selection focusing on two issues; the first issue relates to managing uncertainty provoked by hesitant situations and the second issue relates to the interaction effect of projects on final value of portfolio. Based on the above issues, the hesitant fuzzy weighted averaging (HFWA) operator is applied to aggregate the hesitant fuzzy...

Interactive Multiobjective Fuzzy Random Programming through Level Set Optimization

This paper focuses on multiobjective linear programming problems involving fuzzy random variable coefficients. A new decision making model and Pareto optimal solution concept are proposed using α-level cuts of membership function. It is shown that the problem including both randomness and fuzziness is equivalently transformed into a deterministic problem. An interactive algorithm is proposed in...
