A decision support system for satellite layout integrating multi-objective optimization and multi-attribute decision making

Abstract

A decision support system, including a multi-objective optimization framework and a multi-attribute decision making approach is proposed for satellite equipment layout. Firstly, given three objectives (to minimize the C.G. offset, the cross moments of inertia and the space debris impact risk), we develop a threedimensional layout optimization model. Unlike most of the previous works just focusing on mass characteristics of the system, a space debris impact risk index is developed. Secondly, we develop an efficient optimization framework for the integration of computer-aided design (CAD) software as well as the optimization algorithm to obtain the Pareto front of the layout optimization problem. Thirdly, after obtaining the candidate solutions, we present a multi-attribute decision making approach, which integrates the smart Pareto filter and the correlation coefficient and standard deviation (CCSD) method to select the best tradeoff solutions on the optimal Pareto fronts. Finally, the framework and the decision making approach are applied to a case study of a satellite platform.

Planning Allocation for GTO-GEO Transfer Spacecraft with Triple Orthogonal Gimbaled Thruster Boom

“…It also provides a more efficient transfer scheme for future GEO orbiting satellites with significant engineering application value. However, most current propulsion schemes employ multi-degree-of-freedom space extension arms, which increases the mechanical design difficulty of the propulsion platform and places higher requirements on the overall control system performance [22]. At the same time, the coupling between the adjustment motion of the gimbaled thruster boom and the attitude control and orbit control of the spacecraft platform will be more severe under environmental disturbances [23].…”
