Environment for Qualitative Temporal Reasoning

Objective

The objective of EQUATOR is to bring together existing techniques for reasoning about the behaviour of process-based systems in time, to develop and extend these techniques as necessary, and to make them available for use in the construction of large-scale knowledge-based systems in several industrial and commercial application areas which require them for their future development.
The objective of the project was to bring together existing techniques for reasoning about the behaviour of process based systems in time, to develop and extend these techniques as necessary and to make them available for use in the construction of large scale knowledge based systems in several industrial and commercial application areas which require them for their future development.
The project will deliver a software development environment for time dependent applications within which a system builder can find the reasoning mechanism or mechanisms appropriate to the problem, apply them singly or in combination, and tune them to function, as far as possible, within applicable run time operational constraints. This environment will be designed to meet the needs of a number of specified applications selected for their diversity and economic importance, and will be evaluated by reimplementing 2 of these as demonstrators.

Requirements for time dependent reasoning (TDR) applications have been identified and analysed through numerous industrial case studies (aviation, railways, urban traffic control, failure detection and analysis, production planning, monitoring, etc).
A general representation formalism (GRF) for TDR applications based on event calculus has been specified, as well as a common representation language (CRL). Both GRF and CRL have been validated using the case studies.
The architecture and basic tools of the development platform for time dependent reasoning applications are now complete, and the work focuses on the evaluation through the development of test cases in air traffic control, urban traffic control and telecommunications network diagnosis.
