Classification of group control precedents
Abstract
Introduction: In the context of the development of autonomy for unmanned vehicles, it is important to improve the methods for increasing the level of autonomy. One of such methods is the use of precedents that allow the system to make decisions in the current situation, based on past experience. Purpose: To develop a classification of group management precedents using the hierarchical and faceted method for the effective use of precedents, to estimate the capacity and fill factor of the classification of such precedents. Results: We introduce new definitions of a precedent state, precedent collision, precedent situation and precedent facts. We confirm the applicability of common classification methods – hierarchical and faceted ones – to group management precedents. We present the depth of the hierarchical classification for various classes that is sufficient for solving practical problems. We introduce two new definitions: “core” and “fringe” of a precedent, which are required to build a faceted classification. They make it possible to select several variants of typical precedents, in which the states of the group can described only by the “cores” of features, without paying special attention to the “fringe”. Using the logical-linguistic model as a base we create a facet formula for precedents, taking into account the “core” and “fringe” of the precedent. Finally, we carry out an assessment of the capacity and fill factor of the precedent classification. As a result, the capacity for each classification is determined. The analysis of the features of precedents allows us to conclude that the occurrence of a precedent in group management is a fairly complex phenomenon where various aspects of the precedent are taken into account. On the basis of the classification of precedents, a definition of a group precedent is formulated. Practical relevance: The classification of precedents makes it possible to implement more efficient control of unmanned vehicles, as it facilitates the search for suitable precedents when it is necessary to make a decision during the mission.
