针对实际焦炉推焦作业计划过程中的多炉号乱笺问题,提出一种基于改进蚁群算法的焦炉推焦计划编排方法。首先,给出以恢复推焦串序过程中总惩罚最小为优化目标的焦炉推焦优化调度模型;其次,为了避免蚁群算法进入搜索停滞状态,设置信息素值域来加强算法的搜索能力,并采用具有自适应性的全局更新规则来加快算法后期的收敛速度,进而利用改进的蚁群算法对焦炉优化调度问题进行求解;最后,通过某焦炉厂实际生产数据仿真结果证明,该方法在解决焦炉推焦计划编制问题时具有更好的求解精度和更高的搜索成功率。
In order to solve the problem of multi-heat radiation in real-time coke ovens, a method based on improved ant colony algorithm is proposed. First of all, given the optimal target of coke oven pushing optimization with the goal of minimizing the total penalty in the process of recovering the push-sequence, secondly, in order to avoid the ant colony algorithm entering the search stagnation state, the pheromone range is set to enhance the searching ability of the algorithm , And adaptive global update rules are used to accelerate the convergence speed of the algorithm later, and then the improved ant colony algorithm is used to solve the optimal scheduling problem of coke oven. Finally, the simulation results of the actual production data of a coke oven plant demonstrate that the The method has better solution accuracy and higher search success rate in solving coke oven poking plan.
