The layout problem of weighted circles is a class of layout optimization problems with behavior constraints. Aiming at this NP-hard problem, this paper puts forward a fast heuristic ant colony approach(FHACA). This approach obtains the heuristic information from weighted matrix and uses it to construct the better ants and design parameters of ant colony optimization. The layout schemes of some ants...
Accurate operation data is the foundation of system identification and system analysis. Based on the characteristic of operation parameters in power plant, the method of data selection and data processing was discussed and the correlation analysis of operation parameters was introduced to operation optimization. The correlation coefficients were proposed to measure the related degree between operation...
The rational determination of operation optimization values is very important to economical analysis and operation optimization in power plant. Based on the correlation of operation data, the economical analysis and operation optimization based on data mining was proposed to guide the operation optimization. The basic structure of economical analysis and operation optimization based on data mining...
The determination of the optimal oxygen content is very important in power plant operation optimization. Due to the disadvantages of traditional ways, this paper proposed a new method to decide the optimal oxygen content based on incremental updating data mining. This method could determine the optimal oxygen content and related frequent items by fuzzy quantitative association rule mining algorithm...
As the development of electric industry, more and more real-time data is sent to databases by data acquisition system and large amounts of data are accumulated. Abundant knowledge exists in those historical data. It is meaning to analyze those historical data in electric industry and find useful knowledge and rules from the mass of data to provide better decision support and better adjustment guidance...
Coal-fired boiler combustion system in power plant is a complex multi-input and multi-output plant with strong nonlinear and large time-delay. The determination of the optimal excess air coefficient is very important for economical analysis and operation optimization and it is a difficulty and bottleneck for operation optimization in power plants. Based on the association characteristic in electric...
The equipments in power plant are closely related and interacted, and the relationships among the equipments are manifested by operation data. According to the actual operation data, the potential associations can be found and applied to guide the operation optimization in power plant. The characteristics of operation data and the methods of correlation analysis were discussed in detail to estimate...
