This paper describes an approach to applications of case-based reasoni
ng in design based on utilising design methods used for solving simila
r problems in the past. In order to facilitate the implementation of t
his approach, data structures called MREM (Memory REconstruction Metho
ds) are developed. This is based on Kolodner's theory of reconstructiv
e memory. An MREM based model of design is implemented in a prototype
called CADREM (CAse based Design using REconstruction Methods). CADREM
's casebase contains cases of conceptual structural design of building
