Redesign and reuse in compositional knowledge-based systems

摘要

The paper introduces a task model for the redesign of compositional knowledge-based systems based on a generic task model of design. A generic task model of design provides an abstract description of a design task and a generic structure which can be refined for design tasks in specific domains of application. A generic task model of design, shown to incorporate redesign, is presented and refined to a task model for the redesign of compositional knowledge-based systems. The applicability of this task model is illustrated for the redesign of a diagnostic knowledge-based system.
