中低層建築最適電梯數分析

Optimum Number of Elevators for Moderate Height Buildings

一般電梯運行設計程序只是滿足在一定時間運送所有乘客，本研究修正此一設計方式，令電梯設計目標為使電梯購置及樓地板使用等總成本為最低。以修正方法計算辦公大樓、公寓、學生宿舍、旅館、醫院及教室等六種不同功能之中低層建築物的最適電梯數，得到一般化的結果，可以做為電梯設計的規範。為確定各項參數對電梯數的影響程度，並且以敏感度分析，找出電梯設計的主要影響參數，使業者或建築師能更清楚了解電梯設計的內涵。

The conventional procedure used in the traffic design of elevator systems is to determine the average number of passengers that can be transported in a fixed period of time. In this study, a revised conventional method for lift systems design is formulated to minimize both cost of the elevators and the cost of utilizing the floor space. The model determines the optimum number of elevators for building with six kinds of moderate heights. The results led to a general guidance standards for designing elevator approximately size to serve needs. We examine the sensitivity of the values to change in design variables. Some recommendations for designing elevator systems are drawn.
