With the scale and complexity of aerospace projects raising, how to shorten the development time of aerocomponents has become an emergent problem. In this paper, we focus on the technical needs in Complex Product Development Process Planning (CPDPP) for aerospace projects. The difficulties of designing a complex aero-component result not only from masses of tasks, but also from iterations between coupled tasks. Iteration is a somewhat negative word since it implies re-doing work and often takes a long time to converge during a whole development process.Under the support of researches in the past, this paper specifies the steps of constructing Design structure matrix (DSM) and proposes a method of handling overlapping iteration and sequential iteration, which makes designers integrate all DSMs established from different views and understand products design structure on the whole. Furthermore it proposes a new decoupling method of DSM based on relevant analyses which is evaluated by an index system consisted of sensitivity and changeability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
