Abstract

NASA demonstrated that there are more than 500,000 pieces of space debris around the earth.It is necessary to remove the space junk because they do great harm to the aircraft. How to remove the space junk has become a universal concern.. In this paper, model is established to find the best alternative to remove the space junk. Fuzzy preference decision time-dependent model based on entropy weight and ameliorative AHP are applied to determine the best alternative or combination of alternatives that a private firm could adopt as a commercial opportunity to address the space debris problem. We analyze and calculate the costs, risks, equipment life, the number of space junk which can be cleared and profit operation of space elevator, small satellites, applications of current and magnetic and laser broom to get a best method.Finally, we analyze the relationship between orbit altitude and generality of collision.It is shown that the proposed models are feasible and reliable.
