Facilitating Stakeholder Communication around AI-Enabled Systems and Business Processes

November 21, 2023
Author(s)
Edward Griffor, Matthew Bundas, Chasity Nadeau, Jeannine Shantz, Thanh Nguyen, Marcello Balduccini, Tran Son
Artificial Intelligence (AI) is often critical to the success of modern business processes. Leveraging it, however, is non-trivial. A major hurdle is communication: discussing system requirements among stakeholders with different backgrounds and goals

IoT Capabilities Composition and Decomposition: A Systematic Review

March 22, 2023
Author(s)
Edward Griffor, Khalid Halba, ahmed lbath, Anton Dahbura
Internet of Things (IoT) capabilities are features or services produced by IoT devices. IoT capabilities composition brings existing capabilities together to create a novel service with added value. IoT Capabilities decomposition works the other way around

Formalizing and Reasoning about Supply Chain Contracts between Agents

January 8, 2023
Author(s)
Dylan Flynn, Chasity Nadeau, Jeannine Shantz, Marcello Balduccini, Tran Son, Edward Griffor
Inspired by the recent problems in supply chains, we propose an approach to declarative modeling of contracts between agents that will eventually support reasoning about resilience of and about ways to improve supply chains. Specifically, we present a high

Smart Cities and Communities: A Key Performance Indicators Framework

June 14, 2022
Author(s)
David A. Wollman, Edward Griffor, Chris Greer, Michael Dunaway, Martin Serrano, Martin Burns, Sokwoo Rhee
This publication presents research findings and scientific work that advance the development and progression of smart city and community measurement methodology. The term 'smart,' as used in the phrase 'smart cities,' is defined here as the efficient use

Specifying and Reasoning about CPS through the Lens of the NIST CPS Framework

March 3, 2022
Author(s)
Thanh Nguyen, Matthew Bundas, Tran Son, Marcello Balduccini, Kathleen Campbell Garwood, Edward Griffor
This paper introduces a formal definition of a Cyber-Physical System (CPS) in the spirit of the CPS Framework proposed by the National Institute of Standards and Technology (NIST). It shows that using this definition, various problems related to concerns

A Methodology for Modeling Interoperability for Smart Sensors in Smart Grids

January 1, 2022
Author(s)
Edward Griffor, Kang B. Lee, Gerald J. FitzPatrick, Eugene Song
Smart sensors in smart grids provide real-time data and status of bidirectional flows of energy for monitoring, protection, and control of grid operations to improve reliability and resilience. Smart sensor interoperability is major challenges for smart

A Methodology for Modeling Interoperability for Smart Sensors in Smart Grids

January 1, 2022
Author(s)
Edward Griffor, Eugene Song, Kang B. Lee, Gerald J. FitzPatrick
Smart sensors in smart grids (SGs) can provide real-time data and status of modernized, bidirectional flows of energy, electrical power grids for monitoring, protection, and control of grid operations to improve reliability and resilience. Smart sensor

A Framework for the Composition of IoT and CPS Capabilities

September 9, 2021
Author(s)
Khalid Halba, Edward Griffor, ANTON DAHBURA, ahmed lbath
By 2030, over half-trillion devices will be connected to the internet. With so many devices with a wide range of capabilities, there is a need for a framework for innovation and reuse of IoT and CPS capabilities. Such framework should facilitate

Decision Support for Smart Grid: Using Reasoning to Contextualize Complex Decision Making

June 20, 2019
Author(s)
Edward R. Griffor, David A. Wollman, Patrick Kamongi, Claire Vishik, Michael Huth, Marcello Balduccini
The smart grid is a complex cyber-physical system (CPS) that poses challenges related to scale, integration, interoperability, processes, governance, and human elements. The US National Institute of Standards and Technology (NIST) and its government

Cyber-Physical Systems and Internet of Things

March 7, 2019
Author(s)
Christopher Greer, Martin J. Burns, David Wollman, Edward Griffor
This NIST Special Publication describes the relationship between the phrases "cyber-physical systems" and "Internet of Things." CPS and IoT both refer to trends in integrating digital capabilities, including network connectivity, with physical devices and

Elaborating the Human Aspect of the NIST Framework for Cyber-Physical Systems
