Abstract:In order to manage the progress of manned space projects better, this paper establishes a complete risk assessment system for the progress of space projects, which consists of five aspects, 21 elements and 89 indicators, involving the design, production and testing of space projects. Besides , author establishes a new algorithm model by using the Fuzzy Analytic Hierarchy Process (FAHP) based on the Fuzzy Consistency Matrix , The consistency checking and revising process of the results are integrated into a non-linear programming problem, and optimized by particle swarm optimization (PSO). The weight results satisfying the consistency requirements are obtained. According to the results, the important processes in space project schedule management are identified, so as to improve the efficiency of prior management and ensure the progress of the project. Finally, taking the space application system XX experimental system of space station engineering as an example, and inviting experts in the field to score it, based on the algorithm studied in this paper, the key points of the project's progress risk control are clarified. The rationality and feasibility of the model and method are proved by theoretical analysis and the results of actual project progress, which can be used to control the progress risk of manned space projects. It provides effective technical support with management.
