Data Quality assurance Techniques for a Monitoring and Diagnosis system

International Journal of Plant Engineering and Management 2007年第2期12卷 107-115页

By researching the data quality problem in the monitoring and diagnosis system （MDS） , the method of detecting non-condition data based on the development trend of equipment condition is proposed, and three requirements of criteria for detecting non-condition data： dynamic, syntheses and simplicity are discussed. According to the general mode of data management in MDS, a data quality assurance system （DQAS） comprising data quality monitoring, data quality diagnosis, detection criteria adjusting and artificial confirmation is set up. A route inspection system called MTREE realizes the DQAS. Aiming at vibration data of route inspection, two detecting criteria are made. One is the quality monitoring parameter, which is found through combining and optimizing some fundamental parameters by genetic programming （GP）. The other is the quality diagnosis criterion, i. e. pseudo distance of Spectral-Energy-Vector （SEV） named Adjacent J-divergence, which indicates the variation degree of adjacent data＇s spectral energy distribution. Results show that DQAS, including these two criteria, is effective to improve the data quality of MDS.

Journal of Landscape Research 2018年第2期10卷 75-80页

作者： ZHOU Lin GUO Shang SHU Mia LI Yao Institute of Edible Fungi Shanxi Academy of Agricultural Sciences Shea Labagh Dobberstain San Francisco CA Shanxi Xiu Tong Biotechnology Co. Ltd.

In order to provide consumers with more safe and edible fungus products and to create a faithful social environment of food quality, the edible fungus products quality safety events, as well as their evoked factors and effects on edible fungus industry were discussed in depth in this paper. The performance of edible fungus products quality management is a comprehensive reflection of technical effect, control effect and implementation effect. Among them, the implementation effect is the most important, which refers to the actual implementation effect of quality and safety rules by practitioners of edible fungus industry. Thus, the initiative implementation effect in quality management will be improved, and a quality assurance system in which practitioners are volunteered to participate and implement initiatively the quality standards and regulations so as to provide safe and high-quality products will be established, thereby achieving the best actual implementation effect in quality management.
