The electric power system is among the most critical infrastructures, being a support for many of them and for key resource sectors. In fact, the complex, digital world around us requires electric power for fundamental aspects of most business and consumer activities. Therefore, it is paramount to assure the correct power supply. Following the increasing trend in electricity generation from renewable...
Base on a comprehensive analysis of causes and classification of BIT false alarm, the stochastic characteristics mechanism of BIT false alarm is summarized, the parameters for BIT false alarm assessment is proposed, and the breakthrough of the method of BIT false alarm caused by which the noise analog and the research of BIT modeling and simulation methods considering stochastic characteristics. Therefore,...
With an increasing amount of intermittent renewable energy sources, such as wind and solar energy, there will also be an increasing demand for balancing power. Hydropower, and pumped storage in particular, can be an efficient way of providing the needed flexibility. Hydropower scheduling, particularly for large power systems with large amounts of hydropower, is a very complex task. Therefore there...
Fiber Channel is the new generation network and bus technology, with high property of good compatibility, low latency, high reliability, high fast transmission, distance transmission and so on. Based on periodic and event information, this paper took deterministic and stochastic Petri nets as a tool, to model a simulated FC-AE-ASM network in the Fiber Channel Avionics Environment. It also calculates...
We present analytical results related to a tool management model for a flexible machine equipped with a tool magazine, variable cutting speed, and sensors to monitor tool wear, when tool life due to flank wear is stochastic. Under some regularity conditions, we derive the special structure of decision rules for adjusting the cutting speed as a function of remaining distance, each time a tool change...
A challenging issue in performance evaluation of parallel storage systems through trace-driven simulation is to accurately characterize and emulate I/O behaviors in real applications. The correlation study of inter-arrival times between I/O requests, with an emphasis on I/O-intensive scientific applications, shows the necessity to further study the self-similarity of parallel I/O arrivals. This paper...
The quantity of handling robot (HR) required for effective handling of products among facilities are discused. In the first step, a preliminary solution is obtained by considering the time required for loading and unloading of products, loaded travelling, empty travelling and breakdown of HR. A detailed model, which integrates both operational and cost performance factors such as utilisation of HR,...
Traditional time-dependent reliability analysis methods aim to predict the product failure time based on binary component and system status, which have not considered the influence of some stochastic characters for the reliability such as internal parameters variation and environment factors fluctuation. Current integrated design method considers performance and reliability requirements simultaneously,...
