Mark S. Fox is the Distinguished Professor of Urban Systems Engineering at the University of Toronto. He is a Professor of Industrial Engineering with a cross appointment in the Department of Computer Science, Director Urban Data Centre in the School of Cities, founding director of the Centre for Social Services Engineering, and head of the Enterprise Integration Laboratory.
Prof. Fox is a Fellow of the Association for the Advancement of Artificial Intelligence (AAAI), was a AAAI councilor, and was a co-founder of the AAAI Special Interest Group in Manufacturing. He is a Fellow of the Institute for Electrical and Electronic Engineering (IEEE), and a Fellow of the Engineering Institute of Canada. He was a joint fellow of the Canadian Institute for Advance Research and PRECARN. He is a past holder of the NSERC Industrial Research Chair in Enterprise Integration, and was a Senior Fellow in the Global Cities Institute. He received a B.Sc. in Computer Science from the University of Toronto in 1975, and his Ph.D. in Computer Science from Carnegie-Mellon University in 1983.
Prior to his return to Toronto, he was an Associate Professor of Computer Science and Robotics at Carnegie Mellon University, He was a founding member of the Robotics Institute, and founding director of the Robotics Institute’s Intelligent Systems Laboratory and Center for Integrated Manufacturing Decision Systems.
As director of the Center for Integrated Manufacturing Decision Systems, he led one of the largest efforts in the United States focused on extending and applying Intelligent Systems, including Artificial Intelligence and Operations Research, to engineering and manufacturing problems, including: job-shop scheduling (ISIS/CORTES), project management (Callisto), alloy design (Aladin), facility design (WRIGHT), mechanical design (Design Fusion), cutting fluid selection (GREASE), distribution system analysis (INET), knowledge-based simulation (KBS), and process diagnosis (PDS). This work has been funded by Alcoa Corp., Air Force Office of Scientific Research, Boeing Computer Services, Cincinatti Milacron Inc., Digital Equipment Corp., Chrysler Corp., General Electric Corp., Gulf Oil, Westinghouse Electric Corp., IBM, and McDonnell Douglas Corp.
Prof. Fox’s research career has focused primarily on two questions:
- How to solve “real world” problems in the presence of constraints, and
- How to represent the knowledge required to solve “real world” problems.
Reasoning with Constraints
Prof. Fox’s early research in constraint-directed reasoning focused on manufacturing scheduling (Fox & Smith, 1984). His research introduced the concepts of automated constraint relaxation using utilities, and hierarchical scheduling using levels of abstraction (Fox, 1983). This work also introduced the use of “textures” to guide the search process (Fox et al., 1989; Sadeh & Fox, 1996; Beck et al., 1997) with extensions to distributed scheduling (Sycara et al., 1991), culminating in a unified approach to scheduling (Davis & Fox, 1994; Beck et al., 1998). His research was incorporated into KBLPS logistic planning and scheduling system adopted by the United States Department of Defence (Saks et al., 1993). His research contributed to the formation of Scheduling as a sub-field in Artificial Intelligence.
Representing Knowledge (Ontologies)
In conjunction with his constraint-based reasoning research, Prof. Fox began developing ontologies. Beginning with an ontology for describing distributed, multi-agent systems (Fox, 1979), he continued with ontologies for scheduling (Fox, 1987), and project Management (Sathi et al., 1986).
- activities (Gruninger & Fox, 1994),
- resources (Fadel, 1994; Fadel et al., 1994),
- products (Lin et al., 1997) and requirements (Lin et al., 1996),
- quality (Kim, 1999; Kim et al., 1999),
- activity-based accounting (Tham, 1999), and
- organization (Fox et al., 1998).
More recent his ontology research has focused on:
- knowledge validity and provenance (Fox & Huang, 2005),
- trust (Huang & Fox, 2006; Huang, 2007), and
- human resource skills and competency (Fazel-Zarandi & Fox, 2013).
Prof. Fox’s current research focuses on Smart Cities. In particular, ontologies for modelling cities and their performance (Fox, 2013), causal analysis of crowd sourced data (e.g., analysis of reports provided by citizens to the city), and process mapping and analysis of city services (e.g., social services).
Entrepreneurial and Industry Activities
Prof. Fox was a co-founder (1983) of Carnegie Group Inc, an Artificial Intelligence software company (publicly traded on NASDAQ until acquired in 1998) that focused on engineering, manufacturing, and telecommunications applications. Prof. Fox was also a co-founder (1993), Chairman and CEO of Novator Systems, a pioneering eRetail services and software company.
Prof. Fox was a member of the committee that created the University of Toronto Faculty of Applied Science and Engineering “Hatchery”, and continues to serve on its advisory board. The Hatchery provides an environment, resources and mentoring for undergraduate engineering students to develop their entrepreneurial abilities.
Prof. Fox designed the PDS system (Fox et al., 1983) as a consultant to Westinghouse Electric Corp., which was one of the first realtime sensor-based diagnosis systems. It has been in production use since 1985, and continues today as a Siemen’s service. It was recognized as one of the top 100 engineering achievements of 1986 (IR100).
Prof. Fox was a member of the board and executive committee of Canada’s Walk of Fame from 2000 thru 2008. He was also a member of the board and executive committee of the Miles Nadal Jewish Community Centre from 2003 thru 2013 and held positions as Vice President of Membership, Marketing and Strategy. Currently, he is a member of the board of directors of Ve’ahavta.
