Dynamic development coefficient analysis using grey system theory
Proceedings of 2011 IEEE International Conference on Grey Systems and Intelligent Services, 2011In this paper the value trends of the development coefficient is studied using the grey system theory for the dynamic development coefficient. After a brief introduction of grey system theory, the coefficient trend analysis and the dynamic development coefficient analysis using the grey system are discussed consequently. Next two numerical examples are

Contrasting grey system theory to probability and fuzzy
ACM SIGICE Bulletin, 1995By contrasting grey system theory with probability theory, statistics, and fuzzy systems, we know the features that make the grey system different are:• reality law• grey hazy set (foundation)• small sample (data)• nonrequirement for distribution• Disregard of a priori ...

Missing Data Imputation Based on Grey System Theory
International Journal of Hybrid Information Technology, 2014This paper proposed a new weighted KNN data filling algorithm based on grey correlation analysis (GBWKNN) by researching the nearest neighbor of missing data filling method. It is aimed at that missing data is not sensitive to noise data and combined with grey system theory and the advantage of the K nearest neighbor algorithm. The experimental results

Software reliability estimation in grey system theory
2007 IEEE International Conference on Grey Systems and Intelligent Services, 2007It is necessary for the software system to work in an acceptable degree of reliability and quality. Stochastic modelling, queueing systems and network models, neural networks models, wavelet models, etc are some of interpretative methods to forecast the reliability of software system. But these approaches contain some limitations.

Long‐Term Load Forecasting Using Grey System Theory
Electrical Engineering in Japan, 1995AbstractSupply and demand in power system planning and operation is required to be balanced. An operational reserve for protection against faults or accidental demands also is required. Therefore load forecasting is one of the most important fields and various load forecasting methods have been applied.In this paper the grey system theory which mats ...

Maneuver Target Tracking Based on Grey System Theory
2018 5th International Conference on Systems and Informatics (ICSAI), 2018The result of maneuvering target tracking based on theory of kalman filter depends on the state model of target and the measurement model. When the state model of target is imprecise or is not described by liner space model of state, the result will be volatilization. However, the establishment of mathematical models is complex and difficult. Sometimes,

Technology of QoS evaluation based grey system theory
Proceedings of 2012 2nd International Conference on Computer Science and Network Technology, 2012Grey system theory is a new method that studies less data, poor information uncertainty problems. Grey system theory, with "small sample" of which "partial information is known, some of the information is unknown" and "poor information" uncertainty system as the research object, mainly through the generation and development of "partial" known ...
