To plan ahead to maximize the efficiency of highgrade channel and navigation facilities in Wujiang ,giving full play to the advantages of the Wujiang River golden waterway, rational using of transport work resources, a efficient multicargo anization program should be made so that the whole channel Wujiang cascade hydroprojects district will be eased off. Currently, the qualitative analysis play a main role in the research of shipping anization in the hub region, quantitative analysis is not much and can’t analysis the whole system in a overall view, what’s more, the shipping anization like Wujiang River multicascade hydroprojects issue has not yet been addressed. Network optimization model often be taken used of in solving the plex anization freight transport works, but the limitations goal of work optimization model can not make a prehensive assessment optimization results. Computer simulation technology have gradually entered the field of transportation planning, but simulation technology mainly work out as a tool of validation and evaluation, taking use the simulation technology to optimize will be effected by subjective factor and difficult to find the optimal solution. Based on the above reasons, the following aspects will be taken in the research work. First, qualitative analysis the influence of construction of a multicascade hydroprojects on shipping anization, then based on the characteristics of Wujiang multicascade hydroprojects, improving the exist work optimization model to make out a lowest generalized cost model of shipping anization in Wujiang multicascade hydroprojects region, solving the model to get the initial optimization shipping anization program. on the other hand, introduction the idea of queuing theory to analysis the multicascade 武漢理工大學碩士學位論文 III hydroprojects. Then, on the based of analysis of the discrete freight system of Wujiang multicascade region, building the simulation model in a ideological of objectoriented to simulate and test the initial program to find out the possible problem with the initial program. Finally, taking use of puter simulation technology and mathematical programming method in general to optimize the initial program of Wujiang multicascade hydroprojects shipping anization, getting a reasonable program which can take use of Wujiang multicascade hydroprojects shipping system in a efficient way.

I Abstract................................................................................................ 錯誤 !未定義書簽。 由于烏江流域內(nèi)具有水電樞紐,升船機、港口等多種水運設施, 水運網(wǎng)絡與公路 及鐵路 運輸網(wǎng)絡連接, 使得貨運組織方式 涉及多種運輸方式、多式聯(lián)運及中轉(zhuǎn) 點設置問題。 目前針對樞紐貨運組織方式優(yōu)化的成果較少,張光磊( 2021) [2]針對三峽樞紐區(qū)域運輸組織存在問題,引入 閾 值的概念,通過對三峽船閘的調(diào)度優(yōu)化方案研究 以 提高 船舶 通過量 ,運用評價方法分析各貨類的翻壩可行性及運用 Dijkstra算法得出最佳水 陸 聯(lián)運路徑 綜合確定船舶通過三峽樞紐區(qū)域的水路貨運組織方案,但 該文 缺乏對整個系統(tǒng)貨運組織綜合優(yōu)化 研究 。 FLORIAN M(2021)[7]建立了一個具有層次化 Logit 選擇模式的多種需求條件下多類別多方式的網(wǎng)絡平衡模型。 總的來說,對于多貨種多方式貨運組織優(yōu)化目前主要集中在道路與鐵路 ,對于水路運輸網(wǎng)絡優(yōu)化研究及實踐應用還比較少,且主要集中在流量分配,缺乏對航運系統(tǒng)決策者關心的水路運輸網(wǎng)絡貨運組織優(yōu)化方案中航次數(shù)及船舶數(shù)量的研究,且對多梯級樞紐貨運組織方案優(yōu)化研究還處于空白階段。 李旭宏 (2021) [17]基于 Arena 對物流配送中心分批揀貨策略和單一揀貨策略比較進行了仿真,為配送中心揀貨作業(yè)系統(tǒng)的優(yōu)化提供決策支持、王永輝基于 Arena 對港口泊位作業(yè)系統(tǒng)進行了仿真、 楊神化 (2021) [18]應用Multiagent 系統(tǒng)( MAS)理論和技術,構(gòu)建和開發(fā)了基于 MAS 和船舶操縱模擬器( SHS)的智能港口交通流模擬系統(tǒng),提出了比較實用的港口調(diào)度算法和船舶自動航行算法。 最后,利用多貨種多方式貨流分配模型對烏江多梯級樞紐船舶貨運組織進行優(yōu)化,得到以廣義成本最小的船舶貨運組織優(yōu)化方案。并運用仿真模型對數(shù)學優(yōu)化方法得到的船舶貨運組織方案進行評價。 武漢理工大學碩士學位論文 8 圖 21 烏江多梯級樞紐區(qū)域圖 貨 種貨量 根據(jù)貴州交通廳項目《 烏江高等級航道高效貨運組織關鍵技術研究 》中“ 貴州省烏江干流水路貨運需求預測 ” 部分研究結(jié)果, 2020 年分類貨運量預測結(jié)果見表 21: 武漢理工大學碩士學位論文 9 表 21 分貨類預測 (單位:萬噸) 上行 下行 合計 煤炭 0 磷化工產(chǎn)品 0 金屬礦石 0 礦建材料 30 水泥 木材 0 非金屬礦石 化肥及農(nóng)藥 鹽 糧食 硫磺及合成氨 25 0 25 烤煙 0 茶葉 0 8 8 其它 合計 由表可以看出,烏江流域貨類種類繁多,主要貨種為煤炭、磷化工、礦石、水泥、 硫磺及合成氨及其他大件或機械貨種。貴陽市烏江至長江水運通道一經(jīng)建成
