A Study On The Theory And Approach Of Error Recognition And The Application In Decision Support System

Thousands of miles of dikes destroyed the colony, small errors cause large losses. Small mistake can cause major losses of individual, organization and the country. How to effectively recognize errors in the system, and to eliminate errors, is the problem sought by people.With the development of science and technology, especially the development of Computer technology, Artificial Intelligence and Automation. Error recognition is the main issue studied by computer, systems engineering and other fields. They mainly studied error recognition technology in computer industry fields. It contains voice, character, and biometric identification, uch as voice recognition technology research and its pronunciation error recognition system application[1], Chinese intelligence tools typographical errors in the identification[2] and others. They mainly studied error analysis and fault diagnosis to achieve system optimization in system engineering field.The paper construct a complete error recognition system theory and methodology, including error recognition object, error recognition rules, error recognition methods and the application of referees decision support system, to carry forward the Error Recognition Theory, use systems engineering, mathematics, logic and computer engineering theories and methods, etc.First, combine with the study of faulty logic, use six characteristics such as domain, things, features, value and time; Classify the identified objects by active state, the realization of system, features of the object denoted by T(t) and the value of the object denoted by L(t), discuss the application of the identified objects in object identify; And studied the state of the identified object. Divided the state of the identified object into four states, such as the identified state, the true state, the expected state and the target state. We discussed the relationship between the identified state, the true state and the expected state. Finally, we use1class of4equations AV X<B in Matrix logic equations to transform the identified state into the target state.Second, study the rule in error identification. Study the principles of rule set up, such as scientificity, relative completeness and internal non-contradiction etc.; Analyze the object system conditions T, conclusions J, inherent function GY, objective function MG, and relations R etc., set up the model and steps of object rule’s establishment; Rules are divided into quantitative and non-quantitative rules according to the rules of the index type. Quantitative rules are divided into four types of rules, such as interval index value, fixed index value, trend of small index value and large-scale trend index value. And discusses the different index types rules corresponding to different forms of error function, with certain elements in objects set; Study the operational method of intersection, union, set-difference, and discussed whether there is interaction between the rules.Third, combine with the study of fault diagnosis and error recognition, study several error identification methods, including pre-error analysis, false assumptions analysis, error checking table method, errors and operability methods, according to the particularity of object in the Error Recognition Theory; Establish ’PKR’ error identification method based on the perspective of system. The system is decomposed into the minimum feature set (may be called point sets), key set and path set. Then list the error identification table according to the rules of each object. After then judge the error with the corresponding rules. And finally to achieve the purpose of recognition errors effectively.Finally, the study error identification model of Nan Quan action specification based on error identification theory and method. Use mathematical models, the plane equation, analytic geometry and other methods and tools, formal description the fifteen actions rules in quality (A group) of Nan Quan Routine. study rule’s error function, establish error identification model in compute vision, and illustrate, in order to reduce the recognized difficulty and man-made influence, make more scientific and fair.The paper studied identified objects, rules, identification methods and error identification model of Nan Quan action specification as the starting point and focus, constructed error recognition methods and theories systematically, and the application in referees decision support systems. Not only provides a theoretical support for system errors identification and system optimization, but also provide practical methods and tools for error recognition, error elimination, error avoid, and referee decision support systems in production and management practices.
