In this paper, a generalized method is proposed to predict the output of a typical wind farm with a multi-state probabilistic model. The impacts of ice coating on the wind farm power output (WFPO) on reliability is evaluated in detail. Based on the analysis of the data sets of ice coating loss from the wind farms located in Guizhou, the southern mountainous area in China, the WFPO model is modified...
To obtain the optimal attack position of antisubmarine helicopter in flight pickle, models to calculate airdrop parameters and torpedo's acquisition probability were built on the basis of analysis of flight pickle's attack process. Then simulations were made to analyze the effects of initial relative bearing and initial distance on torpedo's acquisition probability by using Monte Carlo method. The...
Abstract: The reform of the power market promoted the development of the power industry, meanwhile, also brought about the inherent uncertainty. Face the uncertainty of the market, transmission provider need relevant risk management in invest and trade. Based on learning the experience of the risk management in Finance &Insurance industry, this paper introduces the concept and meaning of the risk...
The macro-treatment model of mine geological environment, namely the prevention treatment model, the progressive treatment model and the aftereffect treatment model, was brought forward on the basis of mining level and severity of environmental geology problems. The control factors are emphasized and the scientific measures are advocated in the prevention treatment model. The progressive treatment...
At present, several feature meta-models have been come up with. However, they can't meet the requirements of dynamic Internet environment or software reuse. This paper proposes a feature meta-model based on ontology. In particular, it can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Finally, we give out...
With the popularization of information technology, the development trend of internet is transferring from PC- Internet to Mobile-Internet. More and more enterprises adopt M-commerce business model to achieve competitive advantage. Based on the review of present business model theory, this article clarifies the concept of M-commerce as a kind of emerging business model, and analyses the advantage of...
Based on classical Geom/G/1 model, setup mechanism is introduced and delayed vacation strategy is used, then a delayed vacation Geom/G/1 queue model with setup is formed. Choosing customer departure epoch as embedded point, by the method of embedded Markov chain, the probability generating function (PGF) of queue length is derived, the decomposition of the PGF is analyzed, the formula of average queue...
