Online review driven route planning of green cold chain logistics: considering service attribute preference

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Qubo Yu Xuze Ye Xueying Jiang Shaoquan Ni Kun Liu Xiaowei Liu School of Transportation and Logistics， Southwest Jiaotong University New Corridor Logistics group Co.， Ltd.of Sichuan Port and Shipping Investment National Engineering Laboratory of Integrated Transportation Big data Application Technology， Southwest Jiaotong University

For the long-distance cold chain transportation， this study focuses on green route planning in the cold chain multimodal transport network， considering the customers’ preferences on transport service attributes. To extract customers' preferences from online reviews， we build the bidirectional gated recurrent units (biGRU) and Logit framework. The coefficients representing the preferences for transport service attributes are calculated and integrated into the route planning model. To enhance the reliability of the routes， we utilize fuzzy set theories to describe travel time， transport cost coefficient， and capacity as trapezoidal fuzzy numbers. Then， we develop a fuzzy route planning model aims to minimize transportation cost， damage cost， refrigeration cost， carbon emission cost， and reliability cost. The numerical experiments are conducted on the new land and sea corridor in southwest China. The proposed method can plan the route which meet the customers’ preferences on transportation cost， travel time， reliability and carbon emission. Moreover， logistics companies can strike a balance between cost and reliability by setting confidence coefficients for travel time and capacity. Furthermore， carbon trading policy implements the significant effect on carbon emission reduction in cold chain logistics， when the trading price is 2 RMB per unit.

The springing up of large language models(LLMs)has shifted the community from single-task-orientated natural language processing(NLP)research to a holistic end-to-end multi-task learning *** this line of research endeavors in the area,LLM-based prompting methods have attracted much attention,partially due to the technological advantages brought by prompt engineering(PE)as well as the underlying NLP principles disclosed by various prompting *** supervised learning usually requires training a model based on labeled data and then making *** contrast,PE methods directly use the powerful capabilities of existing LLMs(e.g.,GPT-3 and GPT-4)via composing appropriate prompts,especially under few-shot or zero-shot *** the abundance of studies related to the prompting and the ever-evolving nature of this field,this article aims to 1)illustrate a novel perspective to review existing PE methods within the well-established communication theory framework,2)facilitate a better/deeper understanding of developing trends of existing PE methods used in three typical tasks,and 3)shed light on promising research directions for future PE methods.
