Vsp is both a pivotal tache in logistic distribution optimization and indispensable in electronic commerce. it can increase logistic economic benefit and realize logistic rationalization. the systemic study on the theory and method of vsp is the base on the growth of logistic intensivism, the establishment of modem chain of command, the development of its and ec. now, the problem is not only applied to the field of auto transportation, but also to ship avigation communication electricity industry management computer application etc. the algorithm has been applied into many combinatorial optimization problems such as the trainman ' s shift arrangement in avigation the optimization design of cargo arrangement in ship company
對貨運車輛進行調度優化，可以提高物流經濟效益、實現物流科學化。對貨運車輛調度優化理論與方法進行系統研究是物流集約化發展、建立現代調度指揮系統、發展智能交通運輸系統和開展電子商務的基礎。目前，問題的形式已有很大發展，該問題以不僅僅局限於汽車運輸領域，在水運、航空、通訊、電力、工業管理、計算機應用等領域也有一定的應用，其演算法已用於航空乘務員輪班安排、輪船公司運送貨物經過港口與貨物安排的優化設計、交通車線路安排、生產系統中的計劃與控制等多種組合優化問題。Firstly, this issue analyzed the external environment of the coal transport in qin port, explained the ability of the " three west " coal rails passageway, the trains near the port, and the turnoff of the surrounding ports, then emphasized on the computation and analysis of the rails which connect qin port with the places of coal origin. secondly, it analyzed the rails and surrounding ports developing trend, coal demands, the tendency of large - size of ship, and the port adaptability. finally, based on those analysises, i put forward a plan of the construction of specialized deep - water coal berth for foreign trade coal in the coal fourth phrase of qin huangdao port
本文首先，從分析秦皇島港煤炭運輸的外部環境入手，通過對「三西」煤炭鐵路運輸通路、港口所在地區的鐵路以及周邊港口概況的敘述，著重對秦皇島港鐵路（主要線路：大秦線、京山線、京秦線）的運輸通過能力進行了計算與分析；其次，對鐵路及周邊港口發展趨勢、煤炭市場需求、船舶大型化趨勢和港口適應性進行了分析；最後，在以上諸多分析的基礎上，提出建設深水外貿煤炭專用碼頭的可行性方案，從而改善秦皇島港大型船舶的裝卸條件，形成在外貿煤炭船舶裝卸的比較優勢，提高秦皇島港在外煤運輸市場的競爭力，並對方案未來的實施效果進行了分析。Results show that the improved proposals can effectively lower the raised level of reversed head at no. 2 lock
結果表明，在兩線船閘運行的情況下，改進方案能有效地降低二線船閘反向水頭的壅高。When ships are at their actual voyages the working conditions ( such as loading, depth of drafu ship speed ) and the navigating environments ( such as the sea route, depth of water, wind, wave, current ) are variable to a large extent. the whole during is a procedure of model varying with time nonlinear and large disturbance. the introduction of the intelligent controlling method can contribute to the improvement of automation degree for ship avoiding collision and maneuvering systems
由於船舶的運動在實際的航行過程中隨船舶的工作狀態（如載荷、吃水深度、航速等）及航行環境（如航線、水深、風、浪、流等）的不同而有很大的變化，是一個模型時變、非線性、大幹擾的過程，將智能化控制技術用於其中將會有助於船舶避碰與操縱系統的自動化程度的提高。分享友人
