When a SCADA (Supervisory Control and Data Acquisition) system monitors and manages other complex infrastructures through the use of distributed technologies, it becomes a critical infrastructure by itself: A failure or disruption in any of its components could implicate a serious impact on the performance of the other infrastructures. The connection with other systems makes a SCADA system more...

this study has examined the organizational antecedents and consequences of hypocritical behaviors in interpersonal communication in najafabad public organizations. to this end, proportional questionnaires were distributed among 280 employees of organizations as a sample. to test the hypothesis, the data were fitted to structural equation models based on chi-square, normed chi-square, incrementa...

The seminal work on theory of Supervisory control in Discrete Event Systems was pioneered by Ramadge and Wonham. Taking inspiration from this work, extensive research has been done to extend the theory to real-time. The main problem in the research related to real-time supervisory control is that theories of RW framework are not directly applicable because of infiniteness of state space. This p...

This paper gives a framework of supervisory control of boiler drum level system. The design and implementation of this process is done by the LabVIEW software. The data of the process variables Level from the boiler system need to be logged in a database for further analysis and supervisory control. A LabVIEW based data logging and supervisory control program simulates the process and the gener...

Heaps models are powerful models for concurrent timed discrete event systems. They admit linear description using dioid algebras. Inspired by supervisory control of logical discrete event systems we introduce parallel composition of heap models, called synchronous product, to formally describe the action of supervisor (represented by another heap model) on the system. This additional explicit c...
