DSM-based complex aerospace projects development process design and optimization

Abstract

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.

Defining a New Role of System Architect at the Product Strategy Stage of a MedTech Product Development Through the DSM-Based Method

“…The Design Structure Matrix (DSM) approach proved its utility in various ways. One area of utility is the DSM application to different industrial cases, showing its universal utility among various topics (Eppinger and Browning, 2012), such as aerospace (Xiong et al, 2015), petroleum (Golkar et al, 2009), automotive (Gaertner et al, 2015). Another area of utility is the extension of the method itself towards the cross-domain Domain Mapping Matrix (DMM) approach (Danilovic and Browning, 2007;Danilovic and Browning, 2004) and the Multiple-Domain Matrix (MDM) (Maurer, 2007;Lindemann et al, 2008).…”
