Signature reliability scrutiny of complex communication system utilizing path tracing approach with bounds

It is widely accepted that the reliability of aerospace devices is essential for aircraft during flight because the operational efficiency of aviation systems directly impacts the safety of flight. In complex structures, it is challenging to estimate accurate reliability properly. As a consequence, firstly the complex aerospace communication system is proposed with its logical and graphical representation to evaluate their min-paths and min-cuts via prevalence matrix and least cut matrix respectively. Secondly, we evaluate the accurate reliability function for the proposed system using the matrix-based approach namely the path tracing approach. Its polynomial form will allow the evaluation of the tail signature. Thirdly, by utilizing the tail signature, the signature reliability and cumulative signature have been depicted easily. Then, we deduce the lower and upper constraints for two-terminal reliability and methodologies, which will allow us to enhance the reliability of the proposed system using the Esary-Proschan bound and edge-packing bound with their upper and lower bounds. The reliability makes use of a listed set of min-pathways and a listed set of min-cuts. Lastly, the expected operational lifespan is estimated using the reliability of the provided complex model.
