【摘要】：针对地下立体车库存取车时间过长问题,研究了地下圆筒形立体车库汽车电梯配备数量。根据设计实例的交通调查资料,采用MATLAB模拟了用户存取车过程;运用概率与数理统计理论,分析得到了用户到达时间和电梯运行时间的概率分布;基于排队论,采用系统容量有限制的多服务台模型,研究了汽车电梯配备数量对用户存取车时间的影响,结合用户存取车可承受等待时间,进而可确定该类车库的汽车电梯配置数量,同时分析了用户到达时间概率分布参数λ对用户存取车时间的影响。研究结果表明:用户到达时间服从参数λ为29.71s·veh~(-1)的泊松分布,1,2,3部电梯运行时间服从参数μ为51.82,26.67,18.66s·veh~(-1)的泊松分布,并计算得到了10层地下车库配置2部和3部汽车电梯时的用户存取车平均逗留时间,分别为276.6s和75.8s,建议该类10层地下车库采用3部汽车电梯。结合研究分析的用户到达时间概率分布参数λ对于用户存取车时间的影响,建议该类地下车库3~8层时设置2部汽车电梯,9层及以上时设置3部电梯。所建立的方法可为计算该类车库汽车电梯配备数量提供理论依据。
[Abstract]:In order to solve the problem of long time of storage and storage vehicle in underground solid garage, the quantity of elevator in underground cylinder garage is studied. According to the traffic investigation data of design example, the quantity of elevator in underground cylinder garage is studied. The process of user access vehicle is simulated by MATLAB. By using the theory of probability and mathematical statistics, the probability distribution of user arrival time and elevator running time is obtained. Based on the queuing theory, the influence of the number of vehicle elevator equipment on the access time of the vehicle is studied by using the multi-help desk model with limited system capacity, and combined with the user access vehicle can bear the waiting time. Furthermore, the number of car elevators in this kind of garage can be determined. At the same time, the influence of the time of arrival probability distribution parameter 位 on the time of user access vehicle is analyzed. The results show that the user arrival time service is a Poisson distribution with a parameter 位 of 29.71s. The Poisson distribution of the operating time of 3 elevators from a parameter 渭 of 51.82n 26.67-18.66s 路vehm-1). The average sojourn time of two and three elevators is calculated, which is 276.6s and 75.8s, respectively. It is suggested that three car elevators should be used in this kind of 10 floor underground garage. The influence of the probability distribution parameter 位 of user arrival time on the access time of the vehicle is analyzed in combination with the research. It is suggested that two elevators should be set up on the 8th floor of the underground garage and 3 elevators should be set up on the ninth floor or above. The method can provide a theoretical basis for the calculation of the number of car elevators in this kind of garage.
