【摘要】:公交調(diào)度規(guī)劃是城市綜合治理的重要環(huán)節(jié),是實(shí)現(xiàn)城市建設(shè)現(xiàn)代化的必要過(guò)程。其中,制定科學(xué)、合理的公交發(fā)車計(jì)劃是公交調(diào)度規(guī)劃的核心工作。傳統(tǒng)上大多依據(jù)調(diào)度管理人員的經(jīng)驗(yàn)來(lái)制定公交發(fā)車計(jì)劃,缺乏科學(xué)、有效的手段。另一方面,對(duì)于復(fù)雜的、動(dòng)態(tài)的公交調(diào)度優(yōu)化問(wèn)題,采用優(yōu)化算法來(lái)求解是比較困難的。隨著計(jì)算機(jī)仿真技術(shù)的發(fā)展,為解決這類不確定性問(wèn)題提供了有效的手段和工具。本文正是在這樣的背景下提出對(duì)公交系統(tǒng)優(yōu)化問(wèn)題進(jìn)行研究,嘗試采用仿真的方法來(lái)分析和解決此問(wèn)題。 本文首先回顧和總結(jié)了公交發(fā)車計(jì)劃的相關(guān)知識(shí)和國(guó)內(nèi)外研究現(xiàn)狀,在此基礎(chǔ)上,以單條線路單個(gè)方向上的公交服務(wù)系統(tǒng)為研究對(duì)象,對(duì)現(xiàn)實(shí)復(fù)雜系統(tǒng)進(jìn)行抽象簡(jiǎn)化建立其概念模型,然后使用ExtendSim仿真軟件設(shè)計(jì)和構(gòu)建公交服務(wù)系統(tǒng)仿真模型,最后通過(guò)實(shí)例驗(yàn)證了該公交仿真模型的可行性和有效性。通過(guò)對(duì)仿真數(shù)據(jù)的分析和處理,研究和解決了單條公交線路的公交發(fā)車頻率的優(yōu)化問(wèn)題。 本研究可以為公交調(diào)度管理人員制定公交發(fā)車計(jì)劃提供一定的決策支持,具有較大的實(shí)際意義和參考價(jià)值。
[Abstract]:Bus scheduling planning is an important part of urban comprehensive management and a necessary process to realize the modernization of urban construction. Among them, making scientific and reasonable bus departure plan is the core work of bus dispatch planning. Traditionally, most of the bus departure plans are based on the experience of dispatching managers, and lack of scientific and effective means. On the other hand, it is difficult to solve the complex and dynamic bus scheduling problem by using optimization algorithm. With the development of computer simulation technology, it provides effective means and tools to solve this kind of uncertainty problem. In this paper, the problem of bus system optimization is studied in this paper, and the simulation method is used to analyze and solve the problem. Firstly, this paper reviews and summarizes the relevant knowledge of bus departure plan and the current research situation at home and abroad. On this basis, the public transport service system with a single line in a single direction is taken as the research object. The conceptual model of complex real system is established by abstract simplification, and then the simulation model of bus service system is designed and constructed by using ExtendSim simulation software. Finally, the feasibility and validity of the simulation model are verified by an example. Through the analysis and processing of the simulation data, the optimization of the bus departure frequency of a single bus line is studied and solved. This study can provide some decision support for bus dispatch managers to make bus departure plan, which has great practical significance and reference value.
