The offshore oil and gas industry has recently been going through a digitalisation drive, with use of `smart' equipment using technologies like the Industrial Internet Things (IIoT) Cyber-Physical Systems (ICPS). There also corresponding increase in cyber attacks targeted at companies. Oil production is usually remote locations, requiring access control. This achieved by integrating ICPS, Super...

undermine line authority; and (5) the fact that aspirants to higher staff offices could gain promotion only through approval of influential line executives. If further esearch should prove that staffline behavior of the character presented here is widespread in industry, and if top management should realize how such behavior affects its cost and production goals-and be concerned to improve the ...

Conflicts in schools occur due to the appearance of incompetent teacher. The principal's performance can be optimal or not influenced by collaboration with other school personnel. purpose this study was determine supervisory system principals through academic supervision. research method uses a qualitative library approach using observation, interview, and documentation data collection techniqu...

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...

<p>Cleanroom parameters such as temperature, relative humidity and particle count are vital in maintaining cleanliness. People machines working inside the cleanroom main contributors for sudden changes of separameters. Measurements monitoring these therefore necessary to reduce rejects downtime production micro-electro-mechanical systems (MEMS). This paper presents a method developmentof ...

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...
