The unit train make-up scheme for loaded direction in the heavy haul railway. Issue 1 (11th December 2019) - Wang, Yuqiang
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.
