In safety-critical systems, components must be highly reliable. Once a component's reliability is lower than the criterion, it will be replaced and transferred to be used in another system which does not need such high reliability. The safety virtual age criterion not only relates with the cost of repair actions, but also with the repair degrees and the systempsilas wearing degrees. In this paper,...
The paper describes the research the application of artificial intelligence technology in analyzing engineering quality and proposed a method which bases on the faulty tree analysis of the fuzzy logical system. In practice, the indeterminacy exists in the occurrence probability of basic event. Based on the previous research, this paper adopts the way of expressing the occurrence probability of basic...
By rough programming, we mean the optimization theory dealing with rough decision problems. This paper constructs a general framework of rough chance-constrained programming. We also design a spectrum of rough simulations for computing uncertain functions arising in the area of rough programming. To speed up the process of handling uncertain functions, we train a neural network to approximate uncertain...
With the liberalization of electric market, the customers may have different reliability requirements, which generates different reliability costs to the grid company, that means they should afford different reliability price. An integrated electric power supply reliability differential pricing model was presented considering both the reserve costs and distribution and transmission investment costs...
Power generation adequacy is critical for the reliability of electricity supply service, and therefore its investment draws much attention. This paper builds a dynamic simulation model to solve the setting of two key parameters, the energy price cap and the capacity price in the generation market, and applies this model to various cases to analyze the generation capacity development. Based on the...
Based on analysis of traffic safety of third class highway in western area, the text has adopted 28 more important influence factors as the evaluation index from eight aspects, which is natural condition, route condition, and roadside condition and so on. With the help of safety reliability, it has set up the evaluation index system of third class highway traffic safety. The fuzzy synthetic model...
