summary An approach to developing design systems is presented, informed by the recognition that design criteria are incommensurable. The degree to which an artifact satisfies one criterion cannot be compared to the degree to which it satisfies another. Given this principle, it is not valid to combine different "scores " given to independent features in an evolving design into a global evaluation function. The design framework proposed here represents an alternative to the traditional approaches for combining independent criteria and organizational principles. It is based on the opportunistic nature of designing, the multiplicity of semantics active in a design session, and the dynamics of focus and distraction. By way of illustrating both this characterization of designing and the abstract computational framework on which it is based, a simple system for arranging blocks according to a set of formal massing principles is presented. The massing generator has some important properties that other systems lack, such as dynamism, robustness and the ability to deal with partial designs. Through a comparison with some artificial intelligence methods such as production systems and search, the proposed framework is used as a guideline for developing design systems. This paper focuses on designing as an activity, rather than engaging in an analysis of finished designs with the hope of capturing their syntactic properties. Thus the stress is placed on the generator's behavior, by giving examples of how it converges on a series of design alternatives in a dynamic fashion, avoiding oscillations and blocks.
