内容简介：

It is discussed the interval data fusion procedure intended for determination of an interval to be consistent with maximal number of given initial intervals (not necessary being consistent among each other) and to be with maximal likelihood including a value x∗ that can serve as representative of all the given intervals. An algorithm of the interval fusion with preference aggregation (IF&PA) is proposed and discussed that can be carried out with help of representation of intervals on the real line by weak order relations (or rankings) over a set of discrete values belonging to these intervals. It is possible to determine a consensus ranking for collection of discrete values rankings, corresponding to initial intervals. The highest ranked value, accepted as a result of the fusion, guarantees improved accuracy and robustness of the interval data fusion procedure outputs. It is considered a space of weak orders induced by the intervals, its properties and dimension. A reasonable number choice problem of discrete values, representing the interval data, is investigated. Related to the problem, computing experiment results and recommendations are given. The interval data fusion procedures can be widely applied in interlaboratory comparisons, prediction of fundamental constant values on the base of different measured values, conformity testing, enhancement of multisensor readings accuracy in sensor networks, etc.

Since 1977 he has been working in various positions in the Department of Computer-aided Measurement Systems and Metrology of the TPU. In 1999-2014 he was a Full Professor and a Head of the Department. Now he is a Full Professor of the Division of Automation and Robotics at the TPU. In 1991-2002 many times he acted as a Visiting Researcher in measurement information systems theory at the Department of Computer Science and Information Systems, University of Jyväskylä, Finland. In 2007-2009 he participated in joint researches in Sensor and Information Fusion under the EERSS Programme of the National University of Singapore. In 2016 for three months he was a Visiting Professor at Vignan University, India. He is a member of TC7, Measurement science (in 2006-2012 acted as a Vice-Chairman of the Technical Committee), and of TC1, Education and training in measurement and instrumentation, of the International Measurement Confederation (IMEKO). He is an editor of Sensor Review and reviewer of many international journals. He served as a Session Chair and Program Committee Member of many international conferences. He serves as an expert of the Russian Science Foundation; a member of Higher Certifying Commission's (VAK) expert board on electronics, instrumentation, radio engineering and communication (Moscow); a member of Academic Council of the TPU, etc. He has published over 180 scientific papers. His current research interests include measurement theory, sensor data fusion with preference aggregation, chemical measurements, electrical and magnetic measurements, modeling of measurement procedures and systems.
