The essential thought of navigating algorithm is the abstract force system determine the to - be motion of tugboat based on the motion information of the tugboat and the information from environment . the result of emulation indicates that this method is nice in the quality of real - time . tugboat can avoid obstacle well > truly and arrive the destination 導航算法的基本思想是根據拖輪自身的運動信息和周圍環境的狀態信息，虛力系統通過所獲得的當前綜合信息決定拖輪的未來運動，仿真結果表明該方法實時性好，拖輪能準確躲避障礙物且到達目標點。

In the port , the ships passes in and out the harbor demand tugboat drag , the ships passes in and out the harbor event is a typical dess ( all the ships size , the ship tonnage , the time of ship passes in and out the harbor are random ) , which will bring the certain difficulty to reasonable marshaling for ship team 在港口，船舶進出港需要拖輪拖引，船舶的進出港事件是一個典型離散事件系統(船舶大小、載重噸及進出港時間均是隨機的) ，這為船隊合理配置拖輪帶來一定的難度。

On the above theories foundation , this paper will program simulation software for the port ' s tugboat marshaling , at the moment of designing , for the consumer ' s convenience using , the software will save and maintenance the large data of simulation running by adopting the technique of database 在上述的基礎上，本文開發了港口拖輪配置的仿真系統軟件，在軟件設計時，采用了數據庫的技術來存儲仿真運行時產生的大量數據，方便用戶對仿真數據進行維護。

The research provides with the reference for the pilots and captains on safe control of the vessel maximum velocity with tugboat assistance . it brings forward a new research field in safety assessment of vessel operation , and a new idea to develop the ship - handling simulator 本文的研究結果為引航員和船長安全地控制拖輪助操工況下本船的航速提供了參考依據，為船舶操縱安全評估提出了新的研究方向，也為船舶操縱模型器的研制與開發提供了新思路。

Wisemates company operating the sale of second - hand vessels , cargo ships used to provide secondary tugboats , barges used , second - hand fishing boats , and the import and export of second - hand vessels trading in a wide range of sources of supply and demand information to meet the needs of users 威士美公司經營二手船舶買賣，提供以二手貨船，二手拖船，二手駁船，二手漁船，等二手船的進出口買賣，提供廣泛的貨源供求信息，以滿足廣大用戶的需求。

Shipping putting in or leaving a port needs tugboat to tow . because putting in or leaving a port is a stochastic and discrete matter ( shipping “ s size , load and the time of putting in or leaving a port are all stochastic ) , there is definite difficulty in tugboat ' s marshaling 在港口，船舶進出港需要拖輪拖引，由于船舶的進出是一個離散隨機事件(船舶大小、載重噸及進出港時間均是隨機的) ，因此為拖輪船隊的合理配置帶來一定的難度。

The study has obtained the following conclusion : the increase of tonnage or the decrease of water depth will lead to an obvious decrease of the maximum velocity , while the increase of the tugboat power causes an unconspicuous increase of the maximum velocity 通過本論題的研究，得出以下結論：船舶排水量的增加，水深變淺，極限航速都將減小，且這種減小的趨勢較為明顯；增加拖輪功率，極限航速將增大，但增大的趨勢并不十分明顯。

Simulation optimization technique has been used in many engineering areas , such as manufacture system , chemic industry system , electric power system , transportation system , etc . tugboat team has great significance in port system 大量實際工程問題均可歸結為仿真優化問題，如制造系統、化工系統、電力系統、交通系統等。由于港口物流系統的復雜性及其本身的隨機性，港口設備的合理化配置問題需要使用仿真優化方法來解決。

In allusion to all of the autonomous tugboats within the system of marine simulator being in a complicated dynamic environment , an virtual force guidance system for dynamic motion planning based on intranet transmitting and man - made field of potential is proposed 針對航海模擬器視景系統中自主拖輪均處于復雜的動態環境，提出了一種基于局域網傳輸和人工勢場相結合的虛力導航和運動規劃算法。

And operates along the coastline of 651m berths plus two floating docks with capacities of 70 , 000dwt and 30 , 000dwt respectively . moreover , it is also well equipped with working boats , tugboats , quayside cranes and floating cranes 1997年10月公司率先通過了iso9002質量體系的認證，并在2003年4月順利通過了iso9001 : 2000質量體系的認證，使質量水平和管理水平都踏上了新的臺階。

Heuristic simulation optimization technique is adopted in this paper . a simulation optimization system of tugboat marshaling is also built in this paper , which can give reasonable configuration of tugboat team to port manager 本文利用仿真優化方法的原理，開發了一套港口拖輪配置啟發式仿真優化系統，能得出理論上最佳的拖輪配置方案，輔助港口管理者作出科學的決策。

For the particularity of the port tugboat working process , it ' s difficult to set up simulation model of the port tugboat working process by the traditional single service stage and multi service stage theories 本文運用離散事件仿真理論，采用了事件調度法的仿真策略，利用流程圖法建立港口拖輪作業過程的仿真模型。在設計優化模塊時，采用演化策略來構成優化算法。

On the one hand , the unreasonable marshaling may result in the longer waiting time of the port ships , on the other hand , it may result in the lower efficiency of the tugboat , accordingly waste the port resources 港口拖輪是港口物流系統中重要的設備，如果總體配置不合理，一方面可能造成港口船舶等待時間加長，另一方面可能造成拖輪利用率低和港口資源的浪費。

On the base of analyzing the regulation of port tugboat working , this paper establish simulation model of tugboat working process by the principle of the dess , and realize the model with object - oriented method 本文利用離散系統仿真的原理，在分析港口拖輪作業規律的基礎上，建立了港口拖輪作業過程的仿真模型，并利用面向對象的技術進行實現。

The dess ca n ' t optimize the project of the tugboat allocation , so it must run the simulation program with many allocation projects , and get the best project after evaluating all the project outcome 離散系統仿真并不能得出最佳方案，需要對多種拖輪配置方案進行仿真運行，得出各種方案的仿真運行結果后，再對結果進行評判，選出較優的方案。

Grounded on a comprehensive discussion of the effects of tonnage , loading condition , ratio of water depth to draft and tugboat power , the thesis puts forward the assessment curves as well as the regression formulae 詳細討論了船舶排水量、裝載狀態、水深吃水比和拖輪功率與極限航速的關系，并給出極限航速估算圖譜以及相應的回歸公式。

For the particularity of the the port ' s tugboat working process , it ' s difficult to set up simulation model of the port ' s tugboat working process by the traditional single service stage and multi service stage theories 在建立仿真模型時，由于港口拖輪作業過程的特殊性，不能用傳統的單服務臺和多服務臺的仿真模型來描述。

So it is real significant for suiting the development of the port to study the optimization of the tugboat marshaling in reason and bring forward a reasonable project on tugboat number and horsepower distribution 因此，對拖輪配置進行優化研究，提出拖輪數量及馬力分配的合理方案，以適應港口的發展，具有重要的現實意義。

The simulation software not only provide applied tool for optimizing the marshaling of port ' s tugboat , but also verify the validity of the simulation model , so it has practical worth and theory worth in certain engineering 仿真系統軟件為港口拖輪的優化配置提供了輔助決策，具有一定的工程實用價值和理論價值。
