铁路散装油料收发作业是一个以油料的连续流动作为主体,同时包含多项离散事件的连续/离散混合系统,针对该系统作业流程复杂、难度大、危险性高的特点,建立了油料收发作业的离散速率仿真模型,并对系统的连续性、预知事件、突发事件进行了分析。将模型转换为线性规划问题,在约束条件下计算模型的有效速率,完成了对作业流程、事件调度的仿真,验证了模型的可行性。通过获取作业流程中的动态行为和实时数据对系统进行有效分析,对于合理决策、提高收发油效率、保障作业安全具有一定的参考价值。
The railway bulk oil receiving and dispatching operation is a continuous / discrete hybrid system with continuous flow of oil as the main body and a number of discrete events at the same time. In view of the complex, difficult and dangerous operation of the system, the oil receiving and dispatching operation Discrete rate simulation model, and the continuity of the system, predict events, emergencies were analyzed. The model is transformed into a linear programming problem, and the effective rate of the model is calculated under constraint conditions. The simulation of job flow and event scheduling is completed, and the feasibility of the model is verified. The effective analysis of the system by acquiring dynamic behavior and real-time data in the operation process has some reference value for rational decision-making, improving the efficiency of receiving and sending oil and ensuring the operation safety.
