【摘要】 通过对上班高峰时段的电梯运行情况进行分析,以"最后被运送的乘客的等待时间最短"的"最大最小"原则作为其评价指标,以"电梯运行周期与运行总时间之比等于电梯在一个周期内运送的乘客数与乘客总数之比"的"比例"原则为依据,对高层楼宇中人员流动高峰时段的几种电梯运行方案建立了数学模型进行描述与比较,找到了电梯停靠楼层的最佳方案,并对北京大学第三医院外科楼的运行方案做出定量的数学证明.更多还原

【Abstract】 We analyze the fact of elevator running during the peak time.Using "Max-Min" principle (shortening the waiting time of the last passenger) and "Ratio" principle(the ratio of running period to total time equals to that of the number of passengers transported during the period to the number of total passengers) as index,we design several mathematical models on the arrangement of elevator running during the peak time and compare them. Also a reasonable explanation is given for the elevator arrangement in the building of surgery in Peking University 3rd hospital.更多还原
