Abstract

In traditional Chinese railway operations, train timetable and unit assignment are usually separated from pricing and seat allocation, resulting in a decrease in revenue and an increase in operating costs. In this paper, we study the integrated problem of train timetable, unit assignment, pricing, and seat allocation, where passenger choice behavior is modeled by the multinomial logit (MNL) model. This integration enables us to explicitly capture supply–demand interactions. The problem is formulated as a mixed integer nonlinear programming model with the objective of maximizing total profit. By converting the MNL model into its equivalent convex form, we recast the model as a tractable reformulation, allowing the use of a general-purpose solver to solve practical-sized instances. Based on real data from high-speed railway lines in China, three sets of case studies are conducted to validate the effectiveness and efficiency of the proposed approach.

中国高速铁路供需互动综合列车时刻表
在传统的中国铁路运营中,列车时刻表和动车组分配通常与定价和座位分配相分离,导致收入减少和运营成本增加。在本文中,我们研究了列车时刻表、动车组分配、定价和座位分配的综合问题,其中乘客选择行为由多项式对数(MNL)模型建模。这种整合使我们能够明确捕捉供需互动。问题被表述为一个混合整数非线性编程模型,目标是实现总利润最大化。通过将 MNL 模型转换为等效的凸形式,我们将该模型重塑为一个易于理解的重构模型,从而允许使用通用求解器来解决实际规模的实例。基于中国高速铁路线的真实数据,我们进行了三组案例研究,以验证所提方法的有效性和效率。

期刊介绍: Omega reports on developments in management, including the latest research results and applications. Original contributions and review articles describe the state of the art in specific fields or functions of management, while there are shorter critical assessments of particular management techniques. Other features of the journal are the "Memoranda" section for short communications and "Feedback", a correspondence column. Omega is both stimulating reading and an important source for practising managers, specialists in management services, operational research workers and management scientists, management consultants, academics, students and research personnel throughout the world. The material published is of high quality and relevance, written in a manner which makes it accessible to all of this wide-ranging readership. Preference will be given to papers with implications to the practice of management. Submissions of purely theoretical papers are discouraged. The review of material for publication in the journal reflects this aim.
