Hierarchical task analysis: developments, applications, and extensions.
Hierarchical task analysis (HTA) is a core ergonomics approach with a pedigree of over 30 years continuous use. At its heart, HTA is based upon a theory of performance and has only three governing principles. Originally developed as a means of determining training requirements, there was no way the initial pioneers of HTA could have foreseen the extent of its success. HTA has endured as a way o...
متن کاملLocal Theory Extensions, Hierarchical Reasoning and Applications to Verification
We present some new results on hierarchical and modular reasoning in complex theories, as well as several examples of application domains in which efficient reasoning is possible. We show, in particular, that various phenomena analyzed in the verification literature can be explained in a unified way using the notion of local theory extension.
متن کاملConstructing Hierarchical Task Models Using Invariance Analysis
Hierarchical Task Networks (HTNs) are a common model for encoding knowledge about planning domains in the form of task decompositions. We present a novel algorithm that uses invariant analysis to construct an HTN from the PDDL description of a planning domain and a single representative instance. The algorithm defines two types of composite tasks that interact to achieve the goal of a planning ...
متن کاملIsomorphic Extensions and Applications
If π : (X,T ) → (Z, S) is a topological factor map between uniquely ergodic topological dynamical systems, then (X,T ) is called an isomorphic extension of (Z, S) if π is also a measure-theoretic isomorphism. We consider the case when the systems are minimal and we pay special attention to equicontinuous (Z, S). We first establish a characterization of this type of isomorphic extensions in term...
