Abstract:

In order to determine the different patterns of supplier involvement in collaborative R&D process of aviation complex equipment, the knowledge accumulation function is established according to the information accumulation process of main manufacturers, the rework function is established based on supplier's collaborative degree and dependence degree. Then, a model is established about supplier involvement aiming for involvement time of the supplier and information communication frequency by constructing the global gain variables considering trade-off between product development time and cost, and the criteria for different patterns of supplier involvement obtained. Finally, an example is given to verify the result, which can provide guidance for practical application.

Key words: collaborative R&D of aviation complex equipment, knowledge accumulation function, rework function, optimal involvement time, communication frequency
