Temporal constraint networks

TLDR
It is shown that the STP, which subsumes the major part of Vilain and Kautz's point algebra, can be solved in polynomial time and the applicability of path consistency algorithms as preprocessing of temporal problems is studied, to demonstrate their termination and bound their complexities.

TIGER: real-time situation assessment of dynamic systems

TL;DR: The TIGER ESPRIT Project is investigating a variety of tools and techniques for real-time situation assessment of dynamic systems, including a high-speed rule-based compiler, a situation assessment tool able to monitor dynamic responses over time, qualitative and numerical prediction of turbine response, and model-based diagnosis to help identify unknown faults.

A Probabilistic Approach to Robust Execution of Temporal Plans with Uncertainty

TL;DR: A new more general formalism called the Probabilistic Simple Temporal Problem (PSTP) is developed following a probabilistic approach and used to solve the problem of finding an optimal execution strategy, i.e. a dynamic schedule where scheduling decisions are made on-line.

Verification of temporal scheduling constraints in clinical practice guidelines

TL;DR: This paper presents a suitable verification method that is based on calculating the minimal network of temporal constraints on the execution of guideline activities and yields suggestions for an equivalent, yet more explicit representation of non-minimal constraints.

Consistency in Networks of Relations

TL;DR: The primary aim is to provide an accessible, unified framework, within which to present the algorithms including a new path consistency algorithm, to discuss their relationships and the may applications, both realized and potential of network consistency algorithms.
