摘要：Critical elements in deep space mission reside in that the rover travels over the surrounding undetermined environment of planet and conducts scientific exploration under the ground control via teleoperation system. Such a teleoperation system plays a vital role in the whole deep space mission. Different from other information systems, the teleoperation system cannot be modified once the deep space mission has been launched. Therefore, it must be assessed quantitatively before and during its implementation. Following the "Net Assessment" theory in the field of national defense and taking national military software standards as baseline, the system development process net assessment model covering “Man, Machine, Material, Method, and Environment (4M1E)” is established in this paper. Then the Net Assessment Method (NAM) combined with the Analytic Hierarchy Process (AHP) and Entropy Weight Method (EWM) is proposed to solve the weight vector. In the final part of this paper, the teleoperation system for China’s Chang'e 3 (CE-3) and Chang'e 4 (CE-4) deep space missions is employed as a case study to verify the applicability of this study, meanwhile the untrustworthy elements of the teleoperation system are discovered upon the net assessment result. The work completed in this paper is beneficial to the development process improvement of military information system.
