The main successful keys of product development is risk management, and time- investing and cost in the early stages, so that we don't have to make costly changes in the future. and. Therefore, this paper aims identify and modeling the Effective factors in designing process of complex aerospace products ,
This paper intends for practical purpose and for methodological, is a mixed approach , In the quantitative section whit interviews and fuzzy Delphi surveys of system managers and engineers, these factors identified in the process of development complex aerospace products. , the causal relations of these factors were analyzed using the fuzzy DEMATEL approach In the qualitative section.
The findings and results shows the, identifying and classifying the complex product development process risks in six main categories and 32 risk drivers and also attributes of complex aerospace products in nine categories, and the characteristics of the complex aerospace product development process in three categories. The determining of system engineering as the characteristic of complex product development process is new findings of this paper. Finally, a causal framework provides theoretical relations between these factors. It can be argued that, in addition to taking into account key factors, it also illustrates the hypothesis or theoretical relations between the hypotheses.
