* Each higher layer of the tree operates with a longer legal separation of cookery and execution time than its immediately land layer.
* The lower layers have local tasks, goals, and sensations, and their activities are planned and coordinated by higher layers which do not generally override their decisions. The layers salmagundi a hybrid intelligent system in which the lowest, responsive layers are sub-symbolic. The higher layers, having relaxed time constraints, are capable of argumentation from an abstract world model and performing planning. A stratified task network is a good fit for planning in a hierarchical control system.
Besides conventionalized systems, an animals control systems are proposed to be organized as a hierarchy.
In perceptual control theory, which postulates that an organisms behavior is a bureau of controlling its perceptions, the organisms control systems are suggested to be organized in a hierarchical pattern as their perceptions are constructed so.
[edit] Applications
[edit] Manufacturing, robotics and vehicles
Among the robotic paradigms is the hierarchical paradigm in which a robot operates in a top-down fashion, heavy on planning, especially motion planning. Computer-aided exertion engineering has been a research focus at NIST since the 1980s. Its change Manufacturing Research Facility was used to develop a five-spot layer production control model. In the early nineties DARPA sponsored research to develop distributed (i.e. networked) intelligent control systems for applications such as military command and control systems. NIST built on...If you want to ask a full essay, order it on our website: Ordercustompaper.com
