Mark Stephen Fox (born 1952) is a Canadian computer scientist, Professor of Industrial Engineering and Distinguished Professor of Urban Systems Engineering at the University of Toronto, known for the development of Constraint Directed Scheduling in the 1980s and the TOVE Project to develop an ontological framework for enterprise modeling and enterprise integration in the 1990s.

Biography
Fox received his B.Sc. in Computer Science from the University of Toronto in 1975, and his PhD in Computer Science from the Carnegie Mellon University in 1983 with the thesis "Constraint-directed search: a case-study of job-shop scheduling."
Fox started his academic career at Carnegie Mellon University as Associate Professor of Computer Science and Robotics, where he also headed the Center for Integrated Manufacturing Systems of The Robotics Institute. In 1991 he returned to the University of Toronto, where he was appointed Professor of Industrial Engineering at the University of Toronto. He is also Senior Fellow in the Global Cities Institute at the University of Toronto.
He is elected Fellow of the Association for the Advancement of Artificial Intelligence, and elected fellow of the Canadian Institute for Advance Research.
Work
Fox's current research interests concern smart cities, in particular "ontologies for modelling cities and their performance, 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)."
In the past he has been particularly interested the fields of "enterprise engineering (i.e., information technology for business process engineering), constrained-directed reasoning, a unified theory of scheduling, enterprise modelling (i.e., TOVE) and coordination theory."
TOVE project
The TOVE project, acronym of TOronto Virtual Enterprise project is a project to develop an ontological framework for enterprise integration (EI) based on and suited for enterprise modeling. In the beginning of the 1990s it was initiated by Mark S. Fox and others at the University of Toronto . Initially the project had defined four goals:
- provides a shared terminology for the enterprise that each agent can jointly understand and use,
- defines the meaning of each term (aka semantics) in a precise and as unambiguous manner as possible
- implements the semantics in a set of axioms that will enable TOVE to automatically deduce the answer to many "common sense" questions about the enterprise, and
- defines a symbology for depicting a term or the concept constructed thereof in a graphical context.
The TOVE framework wants to support reasoning about enterprises, and therefore "provides a characterisation of classes of enterprises by sets of assumptions over their processes, goals, and organization constraints." It has been further developed in the fields of concurrent engineering, supply chain management and business process re-engineering.
Enterprise modeling
In the 1995 seminal article "Methodology for the Design and Evaluation of Ontologies" (1995) Grüninger and Fox outline the definition and scope of enterprise modelling, stating:
In enterprise modelling, we want to define the actions performed within an enterprise, and define constraints for plans and schedules which are constructed to satisfy the goals of the enterprise. This leads to the following set of informal competency questions:Publications
