Hierarchical supervisory control of complex Petri nets
… reboot the machine. This thesis is about finding supervisory control policies that enforce livelock-freedom in large complex systems that are modeled using Petri nets. The supervisory policy, when it exists, prevents the occurrence of certain events (i.e. activities) at specific states in such a …

Security against network attacks in supervisory control systems
… and communication capabilities to monitor and control physical processes. In order to do so, communication networks are commonly used to connect sensors, actuators, and controllers to monitor and control physical systems. The use of communication networks increases the vulnerability of the CPS …

Predictive models of procedural human supervisory control behavior
Human supervisory control systems are characterized by the computer-mediated nature of the interactions between one or more operators and a given task. Nuclear power plants, air traffic management and unmanned vehicles operations are examples of such systems. In this context, the role of the …

The role of expert systems in supervisory control applications
The development of control systems that incorporate aspects of Artificial Intelligence into their strategy has become a reality for engineering and manufacturing companies. Expert systems, as a branch of AI technology have attained a foothold in real-time control and in doing so have established …

Modeling human supervisory control in heterogeneous unmanned vehicle systems
… vision for network-centric operations, operator supervisory control of Unmanned Vehicle (UV) teams is likely to be a focal point of future research and development. Due to requirements for interoperability among UVs of varying attributes, heterogeneity in vehicle capabilities and tasks is likely …

Supervisory control of networked discrete event systems with timing structure
In this work, we study the supervisory control problem of Networked Discrete Event Systems with Timing Structure (NDESWTS), that is subject to bounded communication delays and intermittent loss of observations. We assume that the communication between the plant and the supervisor is carried out …

Mitigation of human supervisory control wait times through automation strategies
… network centric operations principles to human supervisory control (HSC) domains means that humans are increasingly being asked to manage multiple simultaneous HSC processes. However, increases in the number of available information sources, volume of information and operational tempo, all which …

Using the non-intrusive load monitor for shipboard supervisory control
… thesis investigates the use of the NILM as a supervisory control system in the engineering plant of gas-turbine-powered vessel. Field tests demonstrate that the NILM can potentially reduce overall sensor count if used in a supervisory control system. To demonstrate the NILM's capabilities in …

Towards Provably Correct Services: Automated Service Composition Via Supervisory Control Synthesis
… dissertation is to leverage the existing work on supervisory control to solve the problem of automated service composition with a focus on control and correctness. Therefore, in this dissertation, we develop a novel formal framework for modeling Web service compositions based on Supervisory …

The human factors aspects of alarms in human supervisory control tasks.
… aspects of industrial alarm systems within human supervisory control tasks. Typically such systems are located in central control rooms, and the information may be presented via visual display units. The thesis develops a human, rather than engineering, centred approach to the assessment, …

Supervisory Control of a Commercial Heating, Ventilating, and Air Conditioning System
The MPC supervisory controller generated 'optimal' setpoints for lower-level single-input, single-output controllers to maximally utilize the control system framework currently used in the industry. Two different supervisory controller configurations were developed and compared with the existing …

Disjunctive normal formula based supervisory control policy for general Petri nets
… every reachable marking. A liveness enforcing supervisory policy (LESP) determines which controllable transition is to be prevented from ring at a marking, to ensure the supervised Petri net (PN) is live. A LESP is said to be minimally restrictive if the following property is true { if a …

STPA Hazard Analysis of Human Supervisory Control of Multiple Unmanned Aerials Systems
… operations are shifting from multiple operators controlling a single-UAS to a single operator supervising multiple-UAS engaged in complex mission sets. To enable this paradigm change, there is wide consensus in the literature that limitations in human cognitive capacity require shifting low-level …

A discrete event simulation model for unstructured supervisory control of unmanned vehicles
… (UV) systems consist of teams of operators controlling a single UV. Technological advances will likely lead to the inversion of this ratio, and automation of low level tasking. These advances will also lead to a growth in UV use in large-scale applications such as urban search and rescue, …

Supervisory control of an autonomous underwater vehicle using an acoustic communication link
In this thesis, I designed and tested a supervisory control scheme for the Odyssey II-class Autonomous Underwater Vehicles that relies on a very-low-data-rate acoustic communication link. A human supervisor communicates with the AUV over a combination radio/acoustic network. The supervisor radios …
