Abstract

The basic structure of a hierarchical control system is a tree, wherein each computational module has a single superior, and one or more subordinate modules. The top module is where the highest level decisions are made and the longest planning horizon exists. Goals and plans generated at this highest level are transmitted to the next lower level where they are decomposed into sequences of subgoals. In general, the decomposition at each level takes into account information derived from: (a) processed input data from sensors that measure the state of the environment, (b) reports from lower control levels as to the state of the control hierarchy itself, and (c) predictions (or expectations) generated by models, knowledge bases, or inference engines.
