由於土地價格高漲，使高層建築迅速增加，為提供高層建築內部便捷服務及節省 ，妥善的電梯系統設計是很重要的，傳統解析法的電梯系統設計過程中有許多假設，無法 表現真實的狀況，為改善此缺點，本研究發展一套模擬高層建築的電梯運行模式，可應用 各類型之高層建築內部交通型態，透過模擬程式之運作，可獲得電梯運行設計的評估績效 ，如平均等待時間、平均車內時間及輸送能力，這些評估績效即可用以評估不同功能大樓 的電梯設計，而求得最佳的電梯數、電梯容量及速度。

　　　　　High-rise building is now being prompted as land prices rise and desirable sites become hard to find. For maximum serviceability and economy, lift system must be planned to the requirements of high-rise building. The conventional procedure used in the traffic design of lift systems was unrealistic because it is dependent on a number of assumptions. The analytical technique cannot access the quality of service provided by the lift system. In order to overcome these difficulties, a second-by-second simulation of an entire lift operation is developed in this study. Some evaluation performances of lift systems design, such as average passenger waiting time, average journey time and handling capacity could be. obtained from the simulation model. These performances are then used to evaluate lift operation and find optimal capacity, speed and number of lift for different kinds of building.
