In reinforcement learning (RL), rewards have been considered the most important channel for understanding an environment’s dynamics and have been very effectively used as a feedback mechanism. However, recently there have been interesting forays into other modes of understanding the environment. Using sporadic supervisory inputs is one such alternative. This brings into the learning process ric...

We have discussed technical issues regarding supervised world perception modeling and task planning of cooperative mobile robots performing tactical tasks in unstructured environment. We have introduced a hierarchy Supervisory Controller for robust cooperative task deployment of heterogeneous semiautonomous robotic vehicles. Primarily, we have described functional and modular architecture of th...

It is well known that the nonblocking supervisory control problem is NP-hard, subject in particular to state space explosion that is exponential in the number of system components. In this paper we propose to manage complexity by organizing the system as a State Tree Structure (STS). STS are an adaptation of state charts to supervisory control theory. Based on STS we present an efficient recurs...

Normally the operator’s interaction with Supervisory Systems developed for an industrial automated process is a manual process, which depends on the operator’s skills and the constant operation’s attention. This work presents the development, application and tests of the expert system denominated SISES “Sistema de Integração de Sistemas Especialistas e Supervisórios”, that means System of Integ...

While the goal of verification is to check whether a model of the system under consideration has a desired property, supervisory control achieves correctness by adding a so-called supervisor that prevents the occurrence of incorrect behaviors to the original system. Supervisory control methods are appealing because they can be much more tractable than the corresponding verification problems. He...

Supervisory control of the mobile robot navigation system has critical importance. The supervisory control software development of mobile robot navigation can be performed in an unknown environment or for controlled robots in a known environment. Finite automata and graph theory are functional tools in modeling the robot navigation system through discrete environment. This research has emphasis...

The authors examined the effects of supervisory guidance (providing instruction to employees) and behavioral integrity (a pattern of word-deed alignment) on employee organizational citizenship behavior (OCB) and deviant behavior. Results revealed a pattern of Supervisory Guidance x Behavioral Integrity interaction effects, such that relationships between guidance and outcome variables were depe...

Because of their nondeterministic nature of behaviour, the supervisory control of manufacturing systems must be carried out in closed loop. This trait greatly increases the size and complexity of the Discrete-Event System (DES)-based supervisorycontrollers of manufacturing systems. In an attempt t o cope with this complexity, a Hybrid Supervisory Controller HSC) i s proposed. It splits pervisor...
