A high and constant machine reliability in combination with low life cycle cost is the key challenge for today's production. Equipping highly integrated production facilities with robust components and monitoring functions combined with the applicable technical services contributes significantly to guaranteeing machine reliability. In this context, binding reliability predictions are demanded within...
This paper discusses application of risk management to transportation projects. Insufficient attention to risk management can lead to significant cost overruns and schedule delays. Successful risk management depends on proper planning and execution. A risk register based approach is a useful starting point, but is insufficient for determining the extent of cost and schedule risk. Using additional...
5000 km high-speed railway with 350 km/h speed will be constructed in China in the next five years. Traction substations convert the high voltage electricity from the public power system to 25 kV single phase electricity, which are implemented to support the high-speed locomotives through the catenary system. These substations and the catenary system form the traction power supply system (TPSS). Researches...
Grid computing is a newly developed technology. Although the developmental tools and techniques for the grid have been extensively studied, the reliability of grid service can not satisfy the real-world application requirements. To resolve this problem, this paper introduces a fault recovery mechanism into grid nodes and gives a constraint on recovery amount. Moreover, a multi-objective optimization...
