Case-Based Reasoning in a Safety Critical Systems Integrated Development Environment

Progress is described in an on-going project, the aim of which is to provide an integrated environment to support the design of safety critical systems. Central to the research is the development and use of an electronic analogy of a designer’s journal, to enable design traceability through the capture and later recall and replay of sequences of design actions. An important aim is to facilitate the production of high quality designs through the reuse of previously proven designs; for this, the application of case-based reasoning is considered to be appropriate. Proposals for the enhancement of the environment, through the provision of case-based design support, are discussed.
