摘要

在燃料和能源价格不断增长的现代条件下,提高工业企业技术过程的能源和资源效率的问题具有特别的相关性。对于包括采矿和化学原料的高温加工在内的能源密集型行业来说,这种情况尤其严重。为了降低复杂化学工艺过程的能源强度,建议利用计算机模拟的可能性,例如,优化现有设备的操作制度。本文研究了从矿山和加工厂堆积场的磷灰石-霞石矿石废料中生产磷矿球团的焙烧输送机各区域炉料加热制度优化的科学和实际问题。优化任务的特殊性(目标函数的非线性、搜索空间的大维度、计算复杂度高)是传统确定性搜索方法使用的显著限制。这导致了种群算法的选择,种群算法基于对集体行为的建模,并以同时处理多个选项的可能性为特征。采用布谷鸟搜索算法求解所述优化任务,该算法的特点是存在少量影响收敛性的“自由”参数。为了选择这些参数的最优值,提出了使用协同进化的思想,即对每个子种群进行不同“设置”的选择算法的多个版本并行启动。处理磷灰石-霞石矿石废料的化学技术系统的管理,考虑到所获得的结果的基础,将最大限度地减少回报的数量,并确保焙烧输送机的节能运行制度。

The use of coevolutionary algorithms for optimizing the operating regimes of the roasting conveyor machine
In modern conditions of constant growth in prices for fuel and energy resources, the problem of increasing the energy and resource efficiency of technological processes of industrial enterprises has acquired particular relevance. It is especially acute for energy-intensive industries, which include high-temperature processing of mining and chemical raw materials. To reduce the energy intensity of complex chemical-technological processes, it is proposed to use the possibilities of computer simulation, for example, to optimize the operating regimes of existing equipment. The article has considered the scientific and practical problem of optimizing the charge heating regimes in various zones of the roasting conveyor machine used to produce phosphorite pellets from apatite-nepheline ore waste stored in dumps of mining and processing plants. The specifics of the optimization task (nonlinearity of the objective function, large dimension of the search space, high computational complexity) are significant limitations for the use of traditional deterministic search methods. It led to the choice of population algorithms, which are based on modeling the collective behavior and are distinguished by the possibility of simultaneous processing of several options. The cuckoo search algorithm, which is distinguished by a small number of “free” parameters that affect the convergence, was used to solve the stated optimization task. To select the optimal values of these parameters, it was proposed to use the idea of coevolution, which consists in the parallel launch of several versions of the selected algorithm with different “settings” for each subpopulation. The management of the chemical-technological system for the processing of apatite-nepheline ore waste, taking into account the basis of the results obtained, will minimize the amount of return and ensure an energy-saving operating regime of the roasting conveyor machine.
