The scientific background that grey systems theory comes into being, the astonishing progress that grey systems theory has made in the world of learning and its wide-ranging applications in the entire spectrum of science, and the characteristics of unascertained systems include incomplete information and inaccuracies in data are presented in this paper. The scientific principle of simplicity and how...
The observation that the world can be seen as grey, or uncertain, is discussed at a fundamental level. Attention is given first to arguments that suggest that the future should be seen as totally unknown, or black. Reasons are given for dismissing these arguments, and then consideration is given to fundamental causes of uncertainty which prevent the world being white or totally known. The treatment...
A grey set can have its characteristic function values restricted by grey numbers, and such a representation makes the operations of grey sets different from other sets. Based on the new concept of whitenisation of grey sets, a series of operations of grey sets are defined and the difference between grey sets and interval-valued fuzzy sets is illustrated.
It is a complex and challenging problem to evaluate the manufacture efficiency of mechanical slicer. Based on the grey relational theory, different evaluation models and algorithms for the manufacture efficiency of mechanical slicer are reviewed in the paper and then a novel grey relational theory-based model is proposed. A numeral example is given to prove that the proposed evaluation model is effective...
Objective: In order to strengthen and standardize the general hospital of traditional Chinese medicine, strengthen the inner construction, highlight the characteristics and advantages of Chinese medicine and improve Chinese medicine services capacity and competitiveness, we decided to study this subject. Method: Through data analysis and face to face interviews, we find the influential factors for...
In this paper a grey weighted relationship prediction pattern is proposed for the soil organic matter content spectral inversion under the uncertainties between soil organic matter contents and spectral characteristics and the theory of grey system. In order to take full use of the information of grey relationship sequences, the maximum grey relationship discrimination principles are improved, by...
After several years' rapid development, grey system theory has been applied in various research areas successfully. However, the application of grey system theory in psychology and medicine is rare. This paper analyses the characteristics of neuropsychological studies, such as the particularity of the study subjects and the specialty of the study scheme. As the traditional statistical method cannot...
An influence factors analysis method for online auditing performance assessment based on AHP (analytic hierarchy process) and GIA (grey incidence analysis) is proposed in this paper according to the requirements of online auditing performance assessments. In this method, a grey incidence model is developed to analyze the influence factors of online auditing performance based on the characteristics...
In this paper the relationship between university R&D input and output of scientific and technological achievements in China is analyzed systematically. By analyzing the present situation of university R&D activities in China, the outputs of scientific and technological achievement are divided into two categories: intermediate outputs and final outputs. Using grey relational analysis method,...
Superior grey relational analysis is used to study the relationship among the parameters of age, casual blood pressure and 24-hour ambulatory blood pressure with left atrial and ventricular structure, and left ventricular filling function in systolic hypertensives (SH). The results show that among the independent variables, 24-hour ambulatory systolic blood pressure (ASBP24) is the most important...
By making an analogy with the human body, the present paper tries to underline the relations between firm's failure causes and its current situation, in terms of the syndrome that can be identified at its level. For this reason, some elements taken from medicine, such as symptoms, causes and syndromes are presented and characterized from the firm point of view. Knowing the type of syndrome and the...
For the grey correlation model in grey clustering method, correlation model of interval number is put forward in this paper. From the point of the principle of gray correlation, in order to avoid the distance between interval numbers, we calculate the correlation coefficient of two interval numbers directly. At last, we study the software development risk factors clustering based on correlation model...
The purpose of this paper is to investigate the granger causality relationship between GDP and coal consumption or coal production in China during the period of 1978–2008, after the policy of economics reform and opening was implemented in China. Results of the cointegration and Granger causality tests show that there exists a unidirectional causality between GDP and coal consumption or coal production...
For the bearing track correlation problems of multi-sensor on the same platform, in this paper an algorithm for bearing track correlation is presented based on grey incidence analysis. In this algorithm each track's azimuth information is considered as a discrete function of time. The grey incidence analysis for multi target track's azimuth information is performed by using the degree of grey incidence...
Distributor selection is an important component of channel design, and in this paper is a novel selection medel is proposed based on grey incidence analysis. First the relevant literature is reviewed and summarized the situation and the limitations of the study. The problems in the process of channel construction of Eastern flour milling corporation and the proposed the propositions of this study...
The real estate industry is very important to our living environment and the development of society. Changzhou, a city in Jiangsu Province, has a special performance in its housing industry compared with surrounding cities, as the housing price of Changzhou is in the lower level of the whole Yangtze River delta. In this paper, grey relation analysis is used to study the factors affecting the house...
The purpose of this paper was to investigate the dynamic relationship of systolic blood pressure (SBP) with heart rate (HR) and plasma endothelin (ET) in reverse-dipper hypertensives using ergodic grey relation analysis (EGRA). To achieve the above goal, seventeen reverse-dipper patients were selected from the borderline or mild-to-moderate hypertensives. SBP and HR were recorded from ambulatory blood...
