This study introduces a green winner determination (GWD) method for fourth-party logistics (4PL) transportation procurement, integrating environmental performance and consensus reaching. The novel approach enhances 4PL operational efficiency and service quality through effective decision support.
Area of Science:
- Operations Research
- Environmental Management
- Supply Chain Management
Background:
- Growing environmental consciousness necessitates green winner determination (GWD) in fourth-party logistics (4PL) transportation procurement.
- Traditional GWD methods often struggle with heterogeneous data and achieving expert consensus.
- 4PLs require robust decision support to balance environmental performance with operational efficiency.
Purpose of the Study:
- To develop a novel GWD method for 4PL transportation service procurement.
- To integrate environmental performance attributes with a consensus reaching process (CRP).
- To enhance 4PL operational efficiency and service quality through improved decision-making.
Main Methods:
- A hybrid multi-criteria decision-making method (HC-VIKOR) combining linguistic terms, interval numbers, and crisp numbers.
- Development of a minimum adjustment consensus model for linguistic evaluations.
- Proposal of an interactive consensus reaching process (CRP) to manage expert disagreements.
- Integration of heterogeneous information processing with CRP for robust winner determination.
Main Results:
- The proposed HC-VIKOR method effectively integrates diverse attribute types and facilitates consensus among experts.
- Sensitivity analysis indicated significant influence of consensus threshold and group utility weight on results.
- The developed method demonstrated superior performance compared to existing approaches in a numerical example.
- The study successfully addressed challenges in handling mixed data types and achieving group consensus.
Conclusions:
- The novel GWD method provides effective decision support for 4PLs in selecting transportation services.
- The integration of environmental performance and CRP advances the field of winner determination.
- The approach enhances 4PLs' ability to improve operational efficiency and service quality sustainably.
