A Logic-Based Incremental Approach to Graph Repair [chapter]

Sven Schneider, Leen Lambers, Fernando Orejas
2019 Lecture Notes in Computer Science  
Graph repair, restoring consistency of a graph, plays a prominent role in several areas of computer science and beyond: For example, in model-driven engineering, the abstract syntax of models is usually  ...  Flexible edit operations temporarily create inconsistent graphs not representing a valid model, thus requiring graph repair.  ...  Some other recent rule-based graph repair approach [13, 20] (also not covered by the survey) proposes so-called change preserving repairs (similar to what we define as delta-preserving).  ...

Bayesian multivariate imperfect repair model

Shey-Huei Sheu, Chin-Chih Chang
2010 Journal of Statistics & Management Systems  
This paper generalizes a multivariate imperfect repair model by adapting a Bayesian approach.  ...  Based on the proposed model, we derive the distribution of waiting time between two successive perfect repairs and its corresponding failure rates.  ...  Perfect repair (or simply replacement) models assume that the item is returned to a "good as new" state immediately after perfect repair.  ...
