The system is formulated into five function modules, and the research problem is to determine one auxiliary maintains plan, including the time allocation and frequency of maintenance. The case of Guangzhou metro is conducted to illustrate the applicability of SOMS, and the results reveal a number of interesting insights into subway maintenance system, i.e., the worksheet can reduce duplication of redundant maintenance work, the repair cost, and the damage caused by frequent disassembly.展开更多

Because most of the photovoltaic power stations are built in the high altitude and remote areas of Tibet, the special climate conditions make the traditional operation and maintenance mode not suitable for the rapid development of photovoltaic power generation industry. Based on the operation and maintenance status of photovoltaic power station equipment, this paper analyzes the difficulties faced by the operation and maintenance of photovoltaic power station in Tibet under the current situation, and deeply explores the innovative design scheme and key measures to realize the functional design of the operation and maintenance platform of photovoltaic power station.展开更多
