【摘要】：面對(duì)大規(guī)模的物流園區(qū)規(guī)劃熱潮,定量化地分析、評(píng)價(jià)和優(yōu)化物流園區(qū)布局方案成為亟待解決的問題。目前國內(nèi)較多的是對(duì)物流園區(qū)規(guī)劃某一部分進(jìn)行定性分析,缺乏定量和整體研究,造成內(nèi)部結(jié)構(gòu)脫節(jié),如確定物流園區(qū)交通系統(tǒng)方案時(shí)忽略了它與功能區(qū)之間的關(guān)系,導(dǎo)致物流園區(qū)內(nèi)道路交通量遠(yuǎn)遠(yuǎn)超過設(shè)計(jì)值或低于設(shè)計(jì)值,運(yùn)營過程中出現(xiàn)了空間不足、集疏運(yùn)交通不暢等問題。針對(duì)物流園區(qū)規(guī)劃中的不足,在系統(tǒng)理論的指導(dǎo)下,本論文基于元胞自動(dòng)機(jī)理論建立了更符合實(shí)際情況的交通模型,準(zhǔn)確地分析了物流園區(qū)內(nèi)道路通行能力,結(jié)合BP神經(jīng)網(wǎng)絡(luò)得出物流園區(qū)內(nèi)道路設(shè)計(jì)方法；根據(jù)物流園區(qū)功能布局模型的普遍性和特殊性,采用遺傳算法和計(jì)算機(jī)仿真技術(shù)建立了多目標(biāo)的功能布局通用優(yōu)化模型,并結(jié)合實(shí)際案例對(duì)規(guī)劃設(shè)計(jì)階段所涉及的關(guān)鍵性問題進(jìn)行了仿真試驗(yàn)研究。論文主要工作包括以下內(nèi)容： (1)通過建模深入分析了物流園區(qū)的交通特性,強(qiáng)調(diào)了其與城市道路交通系統(tǒng)的不同,并從交通流、密度、平均速度三者之間的關(guān)系圖歸納了影響物流園區(qū)內(nèi)部道路交通系統(tǒng)的主要因素。 (2)建立了多目標(biāo)的物流園區(qū)功能布局模型,分析了各功能區(qū)之間的作業(yè)流程及相互關(guān)系,借助遺傳算法和現(xiàn)代仿真技術(shù),研究了物流園區(qū)功能布局模型的優(yōu)化方法和模塊組成。 (3)以物流園區(qū)內(nèi)部交通系統(tǒng)為研究對(duì)象,基于元胞自動(dòng)機(jī)理論提出了更符合園區(qū)交通特性的混合交通流模型,分析了物流園區(qū)集疏運(yùn)系統(tǒng)的復(fù)雜性,并結(jié)合BP神經(jīng)網(wǎng)絡(luò)及其改進(jìn)算法研究了物流園區(qū)內(nèi)部道路設(shè)計(jì)方法。 (4)基于Em-Plant仿真平臺(tái)建立了物流園區(qū)內(nèi)部結(jié)構(gòu)模型,包括功能區(qū)布局模塊、裝卸搬運(yùn)設(shè)備模塊、交通系統(tǒng)模塊,分析了各子系統(tǒng)的組成和實(shí)施過程,提煉了物流園區(qū)內(nèi)車輛行駛路徑及出入口設(shè)置原則。 本文建立了物流園區(qū)功能布局通用優(yōu)化模型,開發(fā)了內(nèi)部道路設(shè)計(jì)實(shí)用方案,不僅為物流園區(qū)布局規(guī)劃設(shè)計(jì)提供了實(shí)用工具,還驗(yàn)證了模型與算法的可行性和有效性,具有一定的工程實(shí)用價(jià)值和理論價(jià)值。
[Abstract]:In the face of the large-scale logistics park planning boom, quantitative analysis, evaluation and optimization of logistics park layout has become an urgent problem. At present, some part of logistics park planning is analyzed qualitatively in our country, and the lack of quantitative and overall research results in the disconnection of internal structure, such as neglecting the relationship between logistics park transportation system and function area when determining the transportation system plan of logistics park. As a result, the traffic volume in the logistics park is far more than the design value or lower than the design value, there are some problems in the operation process, such as lack of space and traffic unobstructed. Under the guidance of system theory, this paper establishes a more practical traffic model based on cellular automata theory, and analyzes the road capacity of logistics park accurately. According to the universality and particularity of the functional layout model of logistics park, the general optimization model of multi-objective functional layout is established by using genetic algorithm and computer simulation technology. Combined with practical cases, the key problems involved in the planning and design phase are simulated and studied. The main work of this paper is as follows: (1) the traffic characteristics of the logistics park are deeply analyzed by modeling, and the difference between the logistics park and the urban road traffic system is emphasized, and the traffic flow and density are analyzed. The relationship between the average speed and the average speed induces the main factors that affect the road traffic system in the logistics park. (2) the multi-objective function layout model of the logistics park is established. Based on the analysis of the operation flow and the relationship among the functional areas, the genetic algorithm and the modern simulation technology are used. The optimization method and module composition of the logistics park functional layout model are studied. (3) taking the internal transportation system of the logistics park as the research object, Based on the cellular automata theory, a hybrid traffic flow model is proposed, which is more consistent with the traffic characteristics of the park, and the complexity of the distribution system of the logistics park is analyzed. Combined with BP neural network and its improved algorithm, the road design method of logistics park is studied. (4) based on Em-Plant simulation platform, the internal structure model of logistics park is established, including function area layout module, loading and unloading equipment module. In the traffic system module, the composition and implementation process of each subsystem are analyzed, and the principles of vehicle routing and the setting of entrance and exit in the logistics park are refined. In this paper, a general optimization model of logistics park functional layout is established, and a practical scheme of internal road design is developed. It not only provides a practical tool for layout planning and design of logistics park, but also verifies the feasibility and validity of the model and algorithm. It has certain engineering practical value and theoretical value.
