A Dependability Evaluation Model Based on AHP-Fuzzy for Real-time Space TT&C Software
Cao Xi-zhen · Journal of Spacecraft TT&C Technology · 2010
With the increase of the scale and complexity of real-time software in space TTC systems,evaluation of the dependability of such software becomes more and more important.However,it is challenging to give an objective and reasonable assessment of the dependability of software.This paper analyzes the quality characteristics of real-time software in space TTC systems and summarizes the corresponding evaluation indicators of dependability.To get a comprehensive assessment of these indicators,a multi-level AHP-fuzzy synthesized evaluation approach is employed.The approach is based on independent test results from a third party to enhance objectiveness and rationality.
