“…It is also reported to be very slow and unable to handle incremental definitions of constraints (Buchanan, 1993). AI planning techniques were used by Fromont and Sriram (1992). Although very general, the planning process for generating the first solution was computationally expensive, especially for small constraint sets.…”

This paper presents an approach to solving constraint satisfaction problems using Asynchronous Teams of autonomous agents (ATeams). The focus for the constraint satisfaction problem is derived from an effort to support spatial layout generation in a conceptual design framework. The constraint specification allows a high-level representation and manipulation of qualitative geometric information. We present a computational technique based on ATeams to instantiate solutions to the constraint satisfaction problem. The technique uses a search for a solution in numerical space. This permits us to handle both qualitative relationships and numerical constraints in a unified framework. We show that simple knowledge, about human spatial reasoning and about the nature of arithmetic operators can be hierarchically encapsulated and exploited efficiently in the search. An example illustrates the generality of the approach for conceptual design. We also present empirical studies that contrast the efficiency of ATeams with a search based on genetic algorithms. Based on these preliminary results, we argue that the ATeams approach elegantly handles arbitrary sets of constraints, is computationally efficient, and hence merits further investigation.

“…COSMOS further provides the inference chain that leads to a particular recommendation, that is, the rationale for providing such a recommendation. • COPLAN (Fromont & Sriram, 1992) provides the constraint handling mechanism needed for keeping consistency of constraints introduced by intents, justifications, and recommendations. • £>O7S77?£>lM (Culbert, 1992) provides the communication mechanism for information transfer among different designers working in different places and at different times.…”

Large-scale engineering projects typically involve many different types of professionals who must interact and communicate with one another. This interaction produces conflicts that need to be resolved. A framework is presented in which the rationale used in a collaborative design environment for designing an artifact is also used for conflict mitigation. The framework contains mechanisms for checking interactions and prompting hypotheses about the reasons for the interactions. These hypotheses, once verified by the designers, improve conflict resolution by assisting them in coordinating and negotiating conflicts. This, in turn, enhances communication during the design process and consequently increases productivity in the engineering industry.

“…However, with a lower strength and poor wear resistance, this material cannot be used in certain applications where excellent strength or good wear resistance are required [1]. In order to improve the wear resistance of pure Cu, several methods have been developed that raise the strength and wear resistance, including internal oxidation [2], chemical vapor deposition (CVD) [3,4], electroplating, electroless plating [5], and other methods [6][7][8]. Among these methods, electroless plating has the advantages of simplicity and greater relative feasibility in terms of changing the characteristics of a pure Cu surface [1].…”
