This paper describes how the structure of initially retrieved conceptual designs are adapted in EADOCS. Specialist operations for structural adaptations are not available from domain knowledge and have to be retrieved from the case-base. Some characteristics of the application domain are:
A small case-base with poor coverage of the design space.
Cases define only a small part of the (intended) design problems that can be solved by their solutions.
No causal relations are defined to relate design requirements to subsolutions.
Design requirements can be satisfied by different configurations that cannot be mutually adapted.
Optimality of configurations cannot be retrieved from the case-base.
Parametric adaptation is solved by heuristic operations and numerical optimisation routines.
A simple and domain independent approach to structural adaptation is presented:
Structural adaptations are retrieved from differences of similar case solutions that satisfy additional design requirements.
This approach is based on several assumptions:
Similar solutions have similar behaviour and functionality.
Design problems and solutions can be categorised and treated at an abstract level.
A prototype solution is available to define the (locally) optimal configuration.
Conservative structural adaptations can be defined.
