Abstract: Assembling process of spacecraft plays a key role in its development cycle.To provide evidence for enterprise to choose the best process plan,method of evaluation of spacecraft’s assembling process plan based on fuzzy comprehensive evaluation and virtual assembly was proposed,in this method,target system of evaluating model was established;targets were evaluated by virtual assembly;then,a fuzzy comprehensive evaluation model was built.Finally,an assembly process of payload of spacecraft was development to illustrate the feasibility and validity of the proposed evaluation method.

Key words: assembly process of spacecraft, fuzzy comprehensive evaluation, virtual assembly, process optimization
