针对目前铁矿石出口料场取料作业人工调度的弊端,对料堆的静态特性和斗轮机取料的动态特性进行深入研究,建立了基于矿物含量约束的等同并行斗轮取料机调度数学模型,并提出一种二阶段组合求解算法,引入待求问题的下界对算法质量进行评价。仿真结果表明:此调度模型具有较好的精确性和适用性;所设计的二阶段组合算法保证了料堆掘取可能的多样性、调度方案的可行性,加强了全局搜索性能,能够在可接受的计算时间内获得稳定的满意解。研究结果可为矿物出口或中转料场的管理策略研究和供料自动调度系统设计提供理论依据。
In view of the drawbacks of the manual operation of the reclaiming operation at the iron ore export material yard, the static characteristics of the material piles and the dynamic characteristics of the bucketwheel reclaiming are studied in depth. The mathematical model of the equivalent parallel bucketwheel reclaimers scheduling based on the mineral content constraints Model, and proposes a two-stage combinatorial solution algorithm, which introduces the lower bound of the problem to be evaluated to evaluate the quality of the algorithm. The simulation results show that the proposed scheduling model has good accuracy and applicability. The designed two-stage combined algorithm ensures the possible diversity of the material heap and the feasibility of the scheduling scheme, and enhances the global search performance. Accepting the calculation of time to obtain a stable and satisfactory solution. The results can provide a theoretical basis for the research on management strategies of mineral export or transit yard and the design of automatic dispatch system.
