Usability and maintainability of the software tools VIOLIN and CORAL

Abstract

The software tools Virtual Acoustic FLyover Simulation (VIOLIN) and AirCraft Engine NOise AuRALization (CORAL) have been developed and continuously expanded in the course of this bachelor's program. So far, the focus was on a clean software programming development as well as the content of the software. However, in the process, the software quality of the tools was less prioritized. In the scope of this thesis, various modifications are implemented and designed in interest of the quality characteristics usability and maintainability and evaluated quantitatively. For this purpose, the quality model of the ISO/IEC 25010 and the complementary metrics defined in the ISO/IEC 25023 are used. The evaluation shows an evident quality improvement for both software tools. However, in doing so, the quality measures of ISO/IEC 25023 are critically reviewed and their informative value are put into question.
