Space Logistics Orbital Chain Design And Management System Examination

Space Logistics Technology is one of the most important ways to ensure the feasibility, reliability, affordability and sustainability of human space missions. The United States started early in the field of space logistics technology, space logistical problems now have been considered as an important aspect in the design process of current U.S. space mission by NASA researchers, this is also a revelation to China. At present, China is to develop a series of deep space exploration activities such as the lunar exploration project, according to China's actual situation of space technology development, the research of space logistics technology is necessary.This paper chose moon mission as background, researched a lot of domestic and foreign space logistics information, built the model of space logistics orbital supply chain and space logistics supply management, then designed a mathematical simulation software, at last analyzed and evaluated the effectiveness of space logistics system.Firstly, this article analogized land-based logistics and space logistics, by comparison to industrial, commercial, military and other related neighborhood supply chain design, found their potential similarity with space logistics, then obtained the general design method, basic principles and design constraints of the space logistics supply chain, eventually formed a preliminary strategy for space logistics. After that we based on the principles of time optimal and fuel optimal to design the supply nodes, staging transportation track, transportation parking orbit, obtained the interplanetary space exploration orbit which met the space logistics requirements, established the network of space logistics supply orbit chain. Then through research to the supplies of interplanetary space exploration missions, considering the uncertainty of space missions as well as consumption rate of different types of supplies, necessity and priority issues, aging and loss, a more accurate supply-demand model was set up. Finally, we integrated this more accurate space logistics management model into the space logistics supply network, and developed an interplanetary logistics supply chain network simulation software in the Matlab environment based on network node. It could optimization the space logistics supply strategies on the basis of ensuring the reliability and feasibility, and gave more information visual display of spacecraft and supplies flow in the logistics network. This software provided an effective simulation tool for design and optimization of the space logistics supply network.
