Real-Time Path Planning of Driverless Mining Trains with Time-Dependent Physical Constraints

While the increased automation levels of production and operation equipment have led to improved productivity mining activity in open pit mines, capacity mine transport system has become a bottleneck. The optimisation is great practical significance reduce cost improve organizational efficiency mines. In this paper, we first formulate multiobjective problem for railway scheduling by introducing set mathematical constraints. As NP-hard, then devise mixed integer programming-based solution solve develop an online framework accordingly. We finally conduct test cases evaluate performance proposed solution. Experimental results demonstrate that efficient able generate train schedule real-time manner.
