Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters.

Abstract:
ARP-4754 was created by SAE and published in the late 1996 to support the development of highly integrated or complex aircraft systems, especially those with intensive use of software (SAE, 1996). It is recognized by the aeronautical authorities as an acceptable means of compliance to system development activities. It has been adopted by the majority of the aircraft manufacturers as a de facto system development guide. ARP-4754 defines a top down development approach starting with the definition of aircraft functions, allocating these functions to systems, and system functions to items that can be implemented by hardware or software. The three specification domains and the link between them are key elements in the ARP-4754 implementation. ARP-4754, as any standard, does not define a specific way to perform these specifications and links. Our proposal is to use Design Structure Matrices – DSMs – to support the modeling of the three ARP-4754 specification domains and also use Domain Mapping Matrices – DMMs – to connect them. The intention is to apply techniques that can help engineers with the control of the system complexity. The DSMs/DMMs was the way chosen to make the system complexity evident.
