Abstract
Purpose
The purpose of this paper is to study the unit train make-up scheme for loaded direction in the heavy haul railway.
Design/methodology/approach
A 0-1 nonlinear integer programming model with the aim of minimizing the idling period between actual train arrival time and expected train arrival time for all loaded unit trains are proposed.
Findings
The proposed model is applied into a case study based on Daqin heavy haul railway. Results show that the proposed model can offer operators an optimal unit train make-up scheme for loaded direction in heavy haul railway.
Originality/value
The proposed model can offer operators an optimal unit train make-up scheme for loaded direction in heavy haul railway.
