【摘要】：能源需求的不斷增加及國(guó)家對(duì)基礎(chǔ)設(shè)施建設(shè)的巨額投資,推動(dòng)了石化行業(yè)、電力行業(yè)、建筑以及機(jī)械制造行業(yè)的快速發(fā)展。這些行業(yè)的興起帶動(dòng)了工程設(shè)備的采購(gòu)和運(yùn)輸,為長(zhǎng)大件運(yùn)輸業(yè)在技術(shù)上的提升提供了新的契機(jī)。單一的運(yùn)輸方式通常適宜運(yùn)距較短的長(zhǎng)大件運(yùn)輸需求,當(dāng)運(yùn)距較遠(yuǎn)時(shí)多式聯(lián)運(yùn)是其常見的運(yùn)輸方式。長(zhǎng)大件貨物具有貨值高、風(fēng)險(xiǎn)大、一次性等特點(diǎn),在長(zhǎng)途運(yùn)輸過(guò)程中不可避免地會(huì)受到運(yùn)輸設(shè)備、路況、天氣狀況、中轉(zhuǎn)換裝等多方面因素的影響,任何環(huán)節(jié)出現(xiàn)紕漏,都可能造成不可估量的損失。因此,在長(zhǎng)大件貨物多式聯(lián)運(yùn)過(guò)程中,除了盡可能選擇成本較低的方案,同時(shí)還要考慮可靠性問(wèn)題。由于不同運(yùn)輸方式、運(yùn)輸路徑、運(yùn)輸方案的可靠性以及運(yùn)輸成本之間通常會(huì)相互沖突,因此,開展基于可靠度的長(zhǎng)大物件多式聯(lián)運(yùn)路徑優(yōu)化研究,對(duì)于使各方的利益達(dá)到均衡狀態(tài),實(shí)現(xiàn)共同利益的最大化,具有一定的現(xiàn)實(shí)意義。本文通過(guò)對(duì)國(guó)內(nèi)外大量的長(zhǎng)大件運(yùn)輸路徑優(yōu)化、多式聯(lián)運(yùn)、可靠度文獻(xiàn)的分析和總結(jié),將基于可靠度的長(zhǎng)大物件多式聯(lián)運(yùn)路徑的優(yōu)化作為研究重點(diǎn),針對(duì)長(zhǎng)大物件特殊性,可靠度相關(guān)概念及多式聯(lián)運(yùn)中各種運(yùn)輸方式的特點(diǎn)進(jìn)行分析。在此基礎(chǔ)上,結(jié)合供需雙方不同的運(yùn)輸需求,從長(zhǎng)大件運(yùn)輸?shù)奶厥庑猿霭l(fā),構(gòu)建了以運(yùn)輸路徑可靠度最高、運(yùn)輸費(fèi)用最低為優(yōu)化目標(biāo)的多目標(biāo)優(yōu)化模型。文中基于快速非支配遺傳算法對(duì)長(zhǎng)大物件多式聯(lián)運(yùn)可靠度-費(fèi)用模型進(jìn)行了算法設(shè)計(jì),建立了NSGA-Ⅱ算法整體框架,得到最優(yōu)的Pareto解集。最后通過(guò)長(zhǎng)大件貨物多式聯(lián)運(yùn)的算例驗(yàn)證了所建模型和算法的合理性,利用MATLAB程序?qū)\(yùn)輸路徑的可靠度和運(yùn)輸費(fèi)用目標(biāo)進(jìn)行了優(yōu)化,得到了一組可行解集,以便決策者根據(jù)不同的需求選擇適合的運(yùn)輸方案。
[Abstract]:The increasing energy demand and the huge national investment in infrastructure construction have promoted the rapid development of petrochemical industry, power industry, construction and machinery manufacturing industry. The rise of these industries has led to the procurement and transportation of engineering equipment, and provides a new opportunity for the technical improvement of the long-term transportation industry. A single mode of transportation is usually suitable for the transportation demand of long and large parts with short distance, and multimodal transportation is a common mode of transportation when the distance is long. Long-term goods have the characteristics of high value, high risk, one-off and so on. In the process of long-distance transportation, they will inevitably be affected by many factors, such as transportation equipment, road conditions, weather conditions, transfer and replacement, etc., and there will be mistakes in any link. Can cause inestimable losses. Therefore, in the process of multimodal transportation of long and long goods, in addition to choosing the scheme with lower cost as much as possible, the reliability problem should be considered at the same time. Because different modes of transportation, transportation paths, reliability of transport schemes and transportation costs usually conflict with each other, the optimization of multimodal transport paths of long and long objects based on reliability is carried out. It has certain practical significance for making the interests of all parties balanced and realizing the maximization of common interests. Through the analysis and summary of a large number of long and large parts transportation path optimization, multimodal transportation and reliability literature at home and abroad, this paper takes the optimization of long object multimodal transportation path based on reliability as the research focus, aiming at the particularity of long and large objects. The related concepts of reliability and the characteristics of various transportation modes in multimodal transportation are analyzed. On this basis, combined with the different transportation needs of both supply and demand, starting from the particularity of long and large parts transportation, a multi-objective optimization model with the highest reliability of transportation path and the lowest transportation cost is constructed. In this paper, the reliability-cost model of multimodal transport of long objects is designed based on the fast non-dominant genetic algorithm, and the overall framework of NSGA- II algorithm is established, and the optimal Pareto solution set is obtained. Finally, the rationality of the model and algorithm is verified by an example of multimodal transportation of long and long goods. The reliability of transportation path and the target of transportation cost are optimized by using MATLAB program, and a set of feasible solutions is obtained. So that decision makers can choose the appropriate transportation scheme according to different needs.
