“起重机+过跨车”铁水物流多场景仿真

Design of Multi-Scenario Simulation of Molten Iron Logistics System with Cranes and Cross-Train AGVs

大型钢铁联合企业倾向于采用"起重机+过跨车"铁水运输物流新工艺,如何评估其安全性和性能是决策者关心的关键问题。采用仿真评估技术,需要解决由于生产处理时间不确定和"避车"等动态因素导致的多场景仿真问题。为此,提出面向对象仿真对象设计方法和基于有限状态自动机动态建模技术。介绍了铁水运输物流过程的仿真系统,并且给出多场景仿真评估流程。有效的提高了仿真系统的灵活性、可配置性和仿真对象的可重用能力。

Iron and steel complexes prefer a new molten iron logistics technology which involves cranes and cross-train AGVs （Automated Guided Vehicle） for transportation. The key concern of decision-makers is how to evaluate the safety and performance of the logistics design. For using simulation, it needs to solve the multi-scenario what-if simulation problems caused by uncertain processing time and crane yielding. An object-oriented simulation design method and finite state automata based modeling techniques were introduced. A multi-scenario simulation procedure was introduced. The proposed techniques can improve the flexibility, configurability and reusability of the simulation system effectively.
