Modeling Method for Enhanced and Generalized Reliability Prediction in Safety-Critical Software with Simplified Model Selection
Abstract
Our proposed approach in this paper presents an integrated software reliability model (CSRM) that combines
multiple software reliability evolution models (SRGMs) of the non-homogeneous Poisson process (NHPP) to achieve a
balance between precision, adaptability, simplicity, and stability. By using machine learning, the CSRM efficiently combines
the strengths of each SRGM while balancing their weaknesses through appropriate evaluation and calibration techniques.
The developed CSRM has been successfully applied and validated to enable more efficient and accurate evaluation of
software component reliability targets in autonomous robotic wheelchairs (ARWs). Based on the validation results, this
novel approach has significantly improved the efficiency of the assessment process to achieve the defined reliability
objectives. It also enables a more accurate assessment of the need for additional test executions and better planning of the
required verification and validation sessions. This innovative approach provides valuable insight into the reliability of the
developed software, especially for software developers who have limited experience in identifying and applying appropriate
SRGMs.
