【摘要】：在煤炭运输路径优化选择问题的研究中,煤炭运输网络在雨雪、泥石流、地震等突发事件下会发生路线的重新选择,选择路线过程带有波动性与随机性,受主观人为因素影响较大。传统的煤炭运输供应链路径选择与运输效率的关系模型建立方法无法对瞬时变化的路线选择进行自适应调整,无法建立包含路线突变情况的约束条件,建立的模型准确性较低。提出基于关联模糊理论的煤炭运输供应链路径选择与运输效率的关系模型建立方法,塑造可量化的煤炭运输供应链网络演化模型,依据供应链网络鲁棒性新测度,根据小范围供应链效率和连同图大小运算网络中单个节点的运输效率,将量化后的鲁棒性与效率的关系划分成两个独立的特征子空间以及非特征子空间,准确描述两者关系。仿真结果表明,在不同的干扰环境下新建模型能够较好地表述煤炭供应链路径选择与效率的关系。
[Abstract]:In the study of coal transportation route optimization selection, coal transportation network will take place in the rain, snow, debris flow, earthquake and other unexpected events to re-choose the route, the process of route selection with volatility and randomness, The traditional method of establishing the relationship between route selection and transport efficiency of coal transportation supply chain can not adapt to the instantaneous change of route selection. It is impossible to establish the constraint condition including route mutation and the accuracy of the established model is low. A method of establishing the relationship model between route selection and transportation efficiency of coal transportation supply chain based on association fuzzy theory is proposed. According to the new measure of supply chain network robustness, according to the small range supply chain efficiency and the transport efficiency of a single node in the network with graph size, the model of coal transport supply chain network evolution can be built. The relationship between robustness and efficiency after quantization is divided into two independent feature subspaces and non-characteristic subspaces, and the relationship between them is described accurately. The simulation results show that, The new model can better describe the relationship between coal supply chain path selection and efficiency.
