Analysis And Processing On Main Contradiction In The Engineering Complex Contradictions

There are a large number of complex contradictory problems in engineering activities. At present, solving complex contradictory problems (ECCP for short) still mainly depends on individual experience and manual operation. How to realize intelligent processing on complex contradictory problems by computer is an urging task in the development of engineering. Study on intelligent processing on engineering complex contradictory problems, will not only provide the basic theory and method for solving them efficiently, but also lay the foundation for the development of intelligent processing software. This will promote the rapid development of information technology in various sectors of national economy.Surrounding intelligent processing on engineering complex contradictory problems, the following research works have been carried out.1. Analysis of complex contradictory problems.There are a large number of complex contradictory problems in the field of construction, environment, control, detection and other engineering fields. Facing up to complex contradictory problems, people often feel at a loss and do not know how to start. Therefore, this paper introduced the granular computing theory and established granular analysis model (ECC_QSCM for short) for engineering complex contradictory problems. Then some specific granular methods and granular steps based on the model were given. The model provides a theoretical basis for the analysis of complex contradictory problems.2. Identification of main contradictionSolving the main contradiction is the key to complex engineering contradictions. The problems often exhibit a remarkably high correlation in a complex engineering contradiction, so solving a contradiction will affect its related problems. It is not scientific to determine the main contradiction simply by the contradictory degree. Therefore, this paper discusses the theory and method of the main contradiction identification in the independent contradiction sets and the relevant contradiction sets from the view of engineering practice, and gives some theorems, process and algorithms.3. Transformation of contradictory problemsProcessing on contradictory problems is to transform condition party or its related matter element in the contradictory information, namely to find out corresponding conversion function. About conversion function setting of incompatible problem, studied the selection of transformation elements and operation, then built corresponding transformation principle, and defined21types of contradictory body transformation, a total of49new transformation operations. This will make the transformation more practical reference. In addition, the opposite problem conversion function obtained is also studied. Established conversion bridge construction principle, put forward four separation principles in construction of separation type transformation, and gave its formal representation and its application examples. This will provide proper guidance for intelligent processing on opposite problems in practical application.4. Research on conductive contradictionTo solve complex contradictory problems, should not only consider the single question processing, but also consider the links between them, namely the conductive contradictions possible caused. After studied on the causes of conductive contradictions often appear in the processing on complex engineering contradictory problems, gave the corresponding solution. This will provide reference for analysis and solution of engineering conductive contradictions.At last, the paper summarized the innovation of research and main research results, also pointed out further work.
