Comprehensive Evaluation on Space Information Network Demonstration Platform Based on Tracking and Data Relay...

Area of Science:

• Space Systems Engineering
• Satellite Communications
• Network Evaluation

Background:

• The Tracking and Data Relay Satellite System (TDRSS) offers global coverage and real-time access for space information networks.
• Existing evaluation methods for TDRSS demonstration platforms face challenges with complex indicators, redundancy, and subjective scoring.

Purpose of the Study:

• To develop a robust evaluation method for TDRSS demonstration platforms.
• To address the complexities of indicator system construction and improve evaluation consistency.

Main Methods:

• Constructed a comprehensive evaluation index system with five criterions, 11 elements, and over 30 indicators using a three-step strategy.
• Applied Analytic Hierarchy Process in Group Decision-Making (AHP-GDM) to enhance evaluation consistency.
• Proposed a high-speed convergence consistency improvement strategy and a method for generating comprehensive judgment matrix aggregation coefficients.

Main Results:

• Successfully constructed a detailed evaluation index system for the TDRSS demonstration platform.
• The proposed AHP-GDM strategy and consistency improvement method effectively enhanced the reliability of evaluation results.
• Numerical experiments confirmed the improved consistency of the comprehensive judgment matrix.

Conclusions:

• The developed evaluation strategy is versatile and feasible for assessing TDRSS development.
• The method provides a more objective and consistent approach to evaluating complex space information network demonstration platforms.
