马尔可夫网络排队模型在电梯配置中的应用

宗群,程义菊,宋军远

《中国工程科学》 2003年第5卷第10期页码 69-72

摘要：

利用马尔可夫网络排队理论建立了电梯交通模型，在此基础上对各服务站的电梯配置交通进行计算，得到电梯的配置参数。通过与传统的电梯配置方法相比较，显示出明显的优越性，也表明了利用马尔可夫网络排队模型进行电梯配置的有效性和可行性。

基于时间-有色Petri网的电梯系统的建模与分析

宗群,窦立谦,程义菊

《中国工程科学》 2004年第6卷第12期页码 51-55

摘要：

根据时间Petri网和有色Petri网的知识，提出了基于时间-有色Petri网（TCPN）的电梯运行模型。依据此模型将电梯在每层的运行情况分类说明。电梯如何运行是由控制命令统一调度，控制命令是由与电梯运行状态相应的颜色集组成。最后举例说明此模型可在单台电梯控制系统和电梯群控系统中应用。

Design and Experimental Research on a New Pipe Rupture Valve

HU Guo-liang, XU Bing, YANG Hua-yong, ZHANG Yi-ding

《机械工程前沿（英文）》 2006年第1卷第1期页码 26-32 doi: 10.1007/s11465-005-0009-4

摘要：

A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system s dynamic performance are analyzed. Experimental research is also carried out using a hydraulic elevator experiment rig. The numerical simulations accord with experimental results in general. Dynamic performance indexes are assessed by the EN81-2 standard. The results show that the newly designed pipe rupture valve meets the designing requirement for hydraulic elevators.

Evacuation strategies for vertical ship lift during initial fire: Integrated application of stairs and elevators

Shu CHEN, Menghan SHANG, Jianping WANG

《工程管理前沿（英文）》 2021年第8卷第1期页码 135-147 doi: 10.1007/s42524-020-0125-1

摘要： Vertical ship lifts (VSLs) are widely used in navigation facilities worldwide because of their efficiency and low cost. Although several researchers have investigated fire evacuation strategies for reducing potential safety hazards in VSLs, an effective and integrated application of stairs and elevators when a fire occurs in a VSL is necessary. Several evacuation routes were analyzed according to VSL structure and evacuation times in this study. Objective function corresponding to the minimum vertical evacuation time and related simulation model was subsequently developed to obtain a cooperative evacuation plan considering different numbers of evacuees. The Three Gorges ship lift was used as an example, and simulation results indicate that number of evacuees and exit selection are the main influencing factors of the total evacuation time in the stair- and elevator-coordinated evacuation mode. Furthermore, the distance between people trapped in ship reception chamber and evacuation exits affects evacuees’ choice of exits. The proposed model can provide a theoretical reference for evacuation research during initial fire events in VSLs.
