Improvement of Adaptable Model Versioning (AMOR) framework for software model versioning using critical pair analysis

Adaptable Model Versioning (AMOR) is a framework intended to be adapted for versioning of model artefacts. AMOR framework is known for some limitations in the operation and conflict detection process, as well as in the conflict resolution process. This paper presents an attempt to improve AMOR framework using Critical Pair Analysis (CPA), a computation conducted to determine potential conflicts between a pair of operations. CPA computation results are used to detect conflicts between operations and also to determine the conflict resolutions. The test results show higher accuracy for the operation detection process, but they also show a slower performance. For the conflict resolution process, the use of CPA provides a fast and accurate result.
