摘要
针对某钢厂需要对扩容改造后生产线的铁水处理能力进行评估论证、探索最佳的车辆配置数量和道路规划方案的问题,提出了采用集中控制的整体架构,建立相应铁水运输调度系统仿真模型的方法。首先,区分主控逻辑和局部逻辑,将核心调度功能浓缩在一个模块中,所有的指令由调度模块通过全局数组的方式向复杂模型的各个局部发布;其次,使用模块解耦、相似模块集成等多种方法来处理模型,将复杂的工艺流程分为走行和工位处理等模块;最后,采用多种技巧化抽象方法来模拟机车和装铁水的鱼雷罐车之间的脱钩与挂钩、机车的调度与等待、工位点分配与整合等逻辑,使仿真模型具有极大的可扩展性。与按照实际生产流程逐个模拟各个工艺处理过程的方法相比,顺利地完成了模型搭建。通过模型仿真确定了生产线中至少需要投入5辆机车,才能满足日处理铁水80罐的设计要求;同时模型为生产线继续扩容改造提供了论证工具。
Production line’s iron melt processing capacity needs to to be evaluated after expansion and reconstruction in a steel mill, and optimal vehicle configuration and road planning need to be explored. A centralized control overall architecture was used to establish the simulation model of corresponding iron melt transportation dispatching system. Firstly, master logic and local logic were distinguished.Core scheduling functions were concentrated in one module.All instructions were issued by the scheduling module to each part of the complex model through a global array. Next, complex methods such as module decoupling and similar module integration were used to process the model, and complex process flow was divided into modules such as running and station processing.At last, a variety of tricky abstract methods were used to simulate the decoupling and hooking between locomotives and torpedo car, locomotive scheduling and waiting, station allocation and integration logic,which made simulation model have great scalability. The model was built more smoothly, compared to the method of simulating individual process one by one according to the actual production process.At least 5 locomotives were needed to be put into the production line to meet the design requirements of 80 tanks for daily processing of molten iron; and the model was provided to evaluate the continued expansion of the production line.
