【摘要】：戰(zhàn)時軍事運輸需面臨更多現(xiàn)實性因素,運輸軌跡常常具備回退、迂回等曲折式前進特征,運輸時間常常超出預期。在戰(zhàn)時軍事路徑規(guī)劃問題中,不僅僅要考慮路徑前進能力,也需要考慮路徑的回退、迂回能力,尤其是突發(fā)事件下的應變抗干擾能力。研究軍事物資運輸問題要與戰(zhàn)時不確性因素相融合,制定滿足時間期限、物資需求、又具備強可靠性的運輸方案,具有更深刻的現(xiàn)實意義。本文主要研究戰(zhàn)時軍事運輸行程時間不確定性問題,分析敵方襲擊事件以及公路阻抗對運輸方案的波動性干擾。分別建立了敵襲事件以及公路阻抗對路網(wǎng)可靠性的負作用模型。為了控制戰(zhàn)時不確定性風險對于軍事決策的影響,本文研究了軍事物流分組運輸對于不確定風險的規(guī)避作用,建立了代表運輸風險大小的運量阻抗模型,并以運量阻抗最小為目標的設(shè)置了分組運輸線性規(guī)劃函數(shù)。在模型的求解階段,使用K優(yōu)路徑算法以及加權(quán)迭代思想求解分組運輸方案。本文模型將會計算出每一條運輸路徑所承擔的建議運輸任務(wù)量,進而為決策人員提供運輸方案的推薦參考。最后本文在經(jīng)典Nguyen Dupuis網(wǎng)絡(luò)地形圖做模型方法的驗證工作,并設(shè)計實現(xiàn)了仿真工具。所做實驗總體可以分為兩部分,一是計算有關(guān)戰(zhàn)時環(huán)境路網(wǎng)行程時間可靠性的相關(guān)數(shù)據(jù)；二是求解戰(zhàn)時分組運輸方案。通過仿真工具的實現(xiàn)與驗證,本文所研究的模型與算法能夠為用戶提供決策能力,用戶可以依據(jù)輔助決策建議綜合多方面因素做出決策方案,所提供的運輸方案合理有效。
[Abstract]:Military transportation in wartime has to face more realistic factors, and the transportation track often has the characteristics of retrogression and detour, and the transportation time often exceeds the expectation. In wartime military path planning, not only the ability of path forward, but also the ability of retrogression and detour should be considered, especially the ability of emergency and anti-jamming. To study the transportation of military materials should be combined with the factors of uncertainty in wartime, and it is of more profound practical significance to make a transportation plan that meets the time limit, material demand and has strong reliability. In this paper, the uncertainty of travel time of military transportation in wartime is studied, and the fluctuating interference of enemy attack and highway impedance on transportation scheme is analyzed. The negative impact models of enemy attack events and highway impedance on the reliability of road network are established respectively. In order to control the influence of uncertain risk on military decision-making in wartime, this paper studies the effect of military logistics grouping transportation on the avoidance of uncertain risk, and establishes a transport volume impedance model, which represents the size of transport risk. The linear programming function of packet transportation is set up in order to minimize the capacity impedance. In the stage of solving the model, the K-optimal path algorithm and the weighted iterative method are used to solve the packet transportation scheme. In this paper, the proposed transport task for each transport route will be calculated, which will provide a recommended reference for the decision makers. At last, this paper does the verification work on the classical Nguyen Dupuis network topographic map, and designs and implements the simulation tool. The experiment can be divided into two parts as a whole, one is to calculate the relative data about the travel time reliability of the environmental network in wartime, the other is to solve the packet transportation scheme in wartime. Through the implementation and verification of the simulation tool, the model and algorithm studied in this paper can provide the decision ability for the user, the user can make the decision plan according to the auxiliary decision suggestion synthesizing various factors, and the transportation scheme provided is reasonable and effective.
