【摘要】:目前航運(yùn)市場(chǎng)仍未走出低迷狀態(tài),運(yùn)力過(guò),F(xiàn)象顯著、市場(chǎng)波動(dòng)頻繁,航運(yùn)企業(yè)都面臨著巨大的經(jīng)營(yíng)壓力。為了更好地應(yīng)對(duì)航運(yùn)市場(chǎng)的挑戰(zhàn),及時(shí)、科學(xué)地進(jìn)行船隊(duì)規(guī)劃至關(guān)重要。雖然關(guān)于船隊(duì)規(guī)劃的研究早已開(kāi)始,但是大部分研究只能在特定的假設(shè)下解決問(wèn)題,距離實(shí)際應(yīng)用還有一定的距離。本文在船隊(duì)規(guī)劃理論與相關(guān)研究的基礎(chǔ)上,細(xì)化對(duì)船隊(duì)規(guī)劃中船型選擇的研究,從船舶適貨性的角度研究船型選擇問(wèn)題,并且充分考慮航運(yùn)市場(chǎng)的不確定性,構(gòu)建了一個(gè)干散貨船隊(duì)隨機(jī)規(guī)劃模型。該模型以規(guī)劃期內(nèi)船隊(duì)運(yùn)營(yíng)總利潤(rùn)最大為目標(biāo),并考慮企業(yè)投資能力,幫助企業(yè)針對(duì)如何購(gòu)置船舶、租賃船舶、調(diào)配船舶等問(wèn)題做出決策。文章通過(guò)求解模型,得出船隊(duì)各規(guī)劃期內(nèi)的最優(yōu)發(fā)展策略及最優(yōu)船舶調(diào)配方案。文章以遠(yuǎn)洋干散貨運(yùn)輸公司S為例,為其干散貨船隊(duì)未來(lái)4年的發(fā)展進(jìn)行規(guī)劃,決定每年船隊(duì)買(mǎi)賣(mài)、租賃和閑置船舶的種類與數(shù)量,并給出船舶調(diào)配方案。研究結(jié)果表明,本文提出的模型更符合市場(chǎng)的實(shí)際情況,具有較強(qiáng)的市場(chǎng)適應(yīng)性;在市場(chǎng)需求波動(dòng)的情況下進(jìn)行船隊(duì)規(guī)劃,船型選擇時(shí)考慮船舶的適貨性能夠提高船隊(duì)?wèi)?yīng)對(duì)風(fēng)險(xiǎn)的能力、提高船隊(duì)經(jīng)營(yíng)的靈活性,幫助企業(yè)增加盈利。
[Abstract]:At present, the shipping market is still not out of the depressed state, the phenomenon of excess capacity is obvious, the market fluctuates frequently, the shipping enterprises are facing enormous operating pressure. In order to better meet the challenges of the shipping market, timely. It is very important to carry out fleet planning scientifically. Although the research on fleet planning has already begun, most of the studies can only solve the problem under certain assumptions. On the basis of fleet planning theory and related research, this paper refines the study of ship type selection in fleet planning, and studies the ship type selection from the point of view of ship cargo suitability. Considering the uncertainty of shipping market, a stochastic programming model of dry bulk fleet is constructed, which aims at the maximum total profit of fleet operation during the planning period, and considers the investment ability of enterprises. This paper helps enterprises to make decisions on how to purchase ships, lease ships, deploy ships, etc. In this paper, the model is solved. The optimal development strategy and the optimal ship deployment scheme in each planning period of the fleet are obtained. Taking the ocean dry bulk transportation company S as an example, the paper plans for the development of its dry bulk fleet in the next 4 years, and decides the annual fleet sale and purchase. The types and the number of chartered and idle ships are also given. The results show that the model proposed in this paper is more suitable for the market and has a strong adaptability to the market. In the case of fluctuating market demand, fleet planning and ship type selection can improve the fleet's ability to deal with risks, improve the flexibility of fleet management, and help enterprises increase their profits.
