【摘要】:汽車保有量的不斷增加,導致停車位嚴重不足。占地面積普遍偏大的傳統(tǒng)停車場無疑會令建筑用地原本很緊張的大中城市不堪重負,最終造成交通嚴重堵塞、汽車無處停放等混亂現(xiàn)象。為緩解此問題,近幾年來自動化立體車庫逐漸發(fā)展并應用起來,但在實際應用中,車庫整體運行效率低,客戶存取車等待時間長,這主要受到車位分配及出入庫調度策略的影響。因此,本文基于這一現(xiàn)狀,重點研究巷道平面移動式立體車庫的車位分配及調度策略,為實際自動化立體車庫調度提供參考。本文研究內容如下:(1)查閱國內外相關文獻,結合立體車庫發(fā)展中存在的問題,本文將發(fā)展前景良好的巷道平面移動式立體車庫入庫車位分配及出入庫調度策略作為重點研究內容。(2)對巷道平面移動式立體車庫結構組成、分類及出入庫作業(yè)流程進行詳細介紹。(3)在對升降機和搬運器相配合的巷道平面移動式立體車庫入庫車位分配時,以入庫距離最短、車位重心最低建立多目標優(yōu)化模型,利用單一遺傳算法(GA)、模擬退火算法(SA)及混合遺傳算法(HGA)對模型分別進行求解,并用MATLAB仿真,結果表明,HGA相對于GA、SA,收斂速度快,優(yōu)化效率高,能有效地縮短入庫距離、降低車位重心。(4)以某巷道平面移動式立體車庫為研究對象,調研統(tǒng)計某個工作日內8:00-11:00期間車輛車主到達時刻,結合排隊論理論知識進行分析,得出該車庫存取車效率低下、客戶平均等待時間長。根據(jù)巷道平面移動式立體車庫出入庫作業(yè)流程及升降機和搬運器不工作時?课恢貌煌,提出聯(lián)合出入和原地等待兩種調度策略,以總調度時間最短建立數(shù)學模型,利用HGA求解模型,通過比較兩種調度策略在不同作業(yè)規(guī)模下的總時間,得出聯(lián)合出入庫策略能有效地縮短總出入庫時間。(5)采用VBA編程語言,以ACCESS2013為開發(fā)平臺,建立巷道平面移動式立體車庫管理系統(tǒng)。本系統(tǒng)可以實現(xiàn)車輛、客戶、繳費、車位、出入庫次數(shù)的查詢與管理,并通過分析系統(tǒng)數(shù)據(jù),掌握車庫運行狀況,為車庫管理提供良好的經(jīng)營決策。
[Abstract]:The increasing number of cars leads to a serious shortage of parking spaces.There is no doubt that the traditional parking lot, which covers a large area on a large scale, will overburden the large and medium-sized cities where the construction land used to be very tight, resulting in a serious traffic jam, no parking place for cars and other chaotic phenomena.In order to alleviate this problem, the automatic three-dimensional garage has been developed and applied in recent years, but in the practical application, the overall running efficiency of the garage is low, and the waiting time for the customer to access the car is long.This is mainly affected by the allocation of parking spaces and the scheduling strategy for incoming and outgoing storage.Therefore, based on the present situation, this paper focuses on the parking space allocation and scheduling strategy of roadway planar mobile stereoscopic garage, which provides a reference for the actual automatic three-dimensional garage scheduling.The contents of this study are as follows: (1) referring to the relevant literature at home and abroad, combining with the problems existing in the development of stereoscopic garage,In this paper, the parking space allocation and dispatching strategy of roadway plane mobile stereoscopic garage with good development prospect are taken as the key research content. The structure of roadway plane mobile stereoscopic garage is composed of.The classification and operation flow of entering and leaving storehouse are introduced in detail. In the allocation of the parking space in the roadway plane mobile stereoscopic garage which is coordinated with hoist and conveyer, the multi-objective optimization model is established with the shortest distance and the lowest center of gravity of the parking space.The single genetic algorithm (GA), simulated annealing algorithm (SA) and hybrid genetic algorithm (HGA) are used to solve the model respectively. The results of MATLAB simulation show that HGA has the advantages of fast convergence speed, high optimization efficiency, and can effectively shorten the storage distance.Reduce the center of gravity of parking space.) take a plane mobile three-dimensional garage of a roadway as the research object, investigate and calculate the arrival time of the vehicle owner during 8: 00-11: 00 in a workday, analyze the theory of queue theory, and draw the conclusion that the efficiency of the vehicle inventory is low.The average waiting time is long.According to the operation flow of plane mobile three-dimensional garage in roadway and the different parking position when the elevator and conveyer are not working, this paper puts forward two scheduling strategies, one is joint access and the other is waiting in situ, and the mathematical model is established with the shortest total dispatching time.By comparing the total time of two scheduling strategies under different job scale by using HGA solution model, it is concluded that the combined input-out strategy can effectively shorten the total input-in-store time. (5) VBA programming language is adopted and ACCESS2013 is used as the development platform.The management system of plane mobile three-dimensional garage of roadway is established.The system can realize the inquiry and management of vehicle, customer, payment, parking space, times of entering and leaving the warehouse, and through analyzing the data of the system, we can master the running condition of the garage and provide a good management decision for the garage management.
