In this paper, the criteria of detection of groups of objects are suggested. These criteria are based on uncertain estimates of objects qualitative attributes. The tasks of the homogeneous and heterogeneous detection of groups of objects are solved. In the homogeneous groups, the values of cognominal qualitative attributes are equal. In the heterogeneous groups, the values of such attributes may differ, but they have to match the a priori set valid combinations. The groups detection is based on the graph-theoretical approach. The decision about the pair of objects belonging to the same group is made by the ternary logic. That allows detecting possible and reliable object groups.
The paper presents the results of studies of a double-valued and a multi-valued elements stock (ES) for digital structures, including robots and flying vehicles, that operates by using linear transformations of current logic signals. A goal of the studies is to develop methods of synthesis and analog circuits engineering solutions of the alternative digital ES with the improved (as compared to the traditional elements stock) technical, technological and operational characteristics.
