Research On Error System Model And Its Application

Since ancient times, as the opposite of the truth, errors have occupied an important position in the history of human understand and transform the world. For error would lead to the results people in general do not hope to see, causing loss or disaster, human have never stop studying error. Since the 1980s, China scholar Professor Guo Kaizhong founded the Error-eliminate Theory, bringing the study of error into a new phase.The study of error system model inherits research results of Error-eliminate Theory, discusses errors based on system, takes errors in system as a research object, and then strives hard to find characteristics, attributes and laws of errors in system. It establishes a system of distinguishing rules and a procedure to effectively distinguish the errors of system. Furthermore, it also lay a solid foundation for further study e the causes of error of system occurs, the mechanism for its formation, the law of its transmission and transformation and the ways to eliminate and avoid it.After a detailed analysis of errors of system and taking the purpose of studing this model into account, we think that the model should include the system model that descripts the model system itself, the subjective function that expresses functions of system human hope to realize, the error function and error value that describes the error quantitatively.This paper starts the study around these four elements. To describe the system itself, we chose the structural model of general system as the system model. In this paper, we not only briefly introduced the model but also developed the model in order to make the study convenient. The structural model of general system includes the objective function that the system can achieve in. But whether the system can realize its subjective function will be decided by the relationship between the objective function and subjective function of the system. After that, studied the function of system by detail, this paper think that the function of system may be divided into subjective and objective. In order to study the relationship between the subjective function and objective function of system, we propose the notation of subjective performance function and objective performance function, and use them to judge the relationship between the subjective function and objective function. From the definition of error in error-eliminate theory, we can see that distinguishing errors depends on the rules. By the need of distinguishing errors of system, after study the characteristics of general distinguishing rule, this paper classifies the distinguishing rules and forms an organic system of distinguishing rules. A major feature of the error system model is quantitative description of the error. Because of this, the model must found error function and calculate the corresponding value of error. This paper not only studies the general natures and types of the error function, but also some general guiding principles by which the error function was established. Undoubtedly, it will be helpful to push the model into practising. After fully studying the four elements constituting the error system model, the paper finally provides the general form of it as well as discusses its characteristics and the process of practising it.Finally, checking the scientificalness, rationality and practicality of the error system model, with an example, this paper makes a preliminary study on its application.
