| Abstract: |
| Objective To solve the varied and uncertain parameters of satellite extension mechanism. Methods The MU-GERT network model was constructed by the graphical review technique, whose parameters were represented by generalized Grey number. Considering the complexity of analysis algorithm in random network, this paper proposed a matrix determinant solution of MU-GERT network model. The algorithm was designed to solve the problem quickly and accurately by computer. Results The MU-GERT network model was used to calculate the time of making a qualified satellite extension mechanism when the probability was uncertain, to simulate the expectations and opportunities for producing a qualified satellite extension mechanism when the time was uncertain. Conclusion It provides references for the application of graphical evaluation review technique on the development of satellite extension mechanism. |
