铁路散装油料收发作业的建模与仿真

Modeling and Simulation on Railway Bulk Oil Transit Operations

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 transit operation is a hybrid(discrete/continuous) system because of the main body of the continuous flow oil and a variety of discrete events. According to the system's characteristics of complex process, great difficulty, high risk, the oil transit operation model was established based on discrete rate simulation and system's continuity, predict events, emergencies were analyzed. The model was converted into linear programming, the effective rate was calculated under constraints, and the operation process and event scheduling was simulated. It was verified that the model is feasible. By obtaining the dynamic behavior and real-time data, its efficiency was analyzed considering that it has reference on making reasonable decision, improving the process efficiency and assuring safety.
