摘要
为检测和分析铁路货场仓储作业系统现状,实现系统资源配置优化,提出了CIMFlow工作流概念模型与Flexsim系统仿真模型相结合的建模方法,同时提出铁路货场仓储作业系统资源配置优化计算方法,辅助实施系统优化。实验结果表明,该模型和方法能够准确反映系统实际运营状况,并在总费用最低的前提下,保证各资源利用率均达到70%左右的最优水平,从而提高铁路货场仓储作业系统的运营效率。
To inspect and analyze the warehousing operation system in the railway yard , and implement the resource allocation optimization , a modelling method of combining CIMFlow workflow conceptual model and Flexsim system simulation model is proposed .Meanwhile , the resource allocation optimization calcu-lating method for the warehousing operation system in the railway yard is given to help the system optimiza-tion .The experimental results indicate that this model and method can provide an accurate reflection to the real operation of the system , and also can insure the utilization rate of the system resources reaching the optimal level of 70%at the lowest total cost , and thus improving the operation efficiency of the warehou-sing operation system in the railway yard .
