【摘要】：在煤炭運輸路徑優(yōu)化選擇問題的研究中,煤炭運輸網(wǎng)絡(luò)在雨雪、泥石流、地震等突發(fā)事件下會發(fā)生路線的重新選擇,選擇路線過程帶有波動性與隨機性,受主觀人為因素影響較大。傳統(tǒng)的煤炭運輸供應(yīng)鏈路徑選擇與運輸效率的關(guān)系模型建立方法無法對瞬時變化的路線選擇進(jìn)行自適應(yīng)調(diào)整,無法建立包含路線突變情況的約束條件,建立的模型準(zhǔn)確性較低。提出基于關(guān)聯(lián)模糊理論的煤炭運輸供應(yīng)鏈路徑選擇與運輸效率的關(guān)系模型建立方法,塑造可量化的煤炭運輸供應(yīng)鏈網(wǎng)絡(luò)演化模型,依據(jù)供應(yīng)鏈網(wǎng)絡(luò)魯棒性新測度,根據(jù)小范圍供應(yīng)鏈效率和連同圖大小運算網(wǎng)絡(luò)中單個節(jié)點的運輸效率,將量化后的魯棒性與效率的關(guān)系劃分成兩個獨立的特征子空間以及非特征子空間,準(zhǔn)確描述兩者關(guān)系。仿真結(jié)果表明,在不同的干擾環(huán)境下新建模型能夠較好地表述煤炭供應(yīng)鏈路徑選擇與效率的關(guān)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.
