Abstract: Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that the laminate design problem is a good candidate for implementation with a constraint network because it does not involve complex branching, which is better supported by a procedural language. In addition, the ability of constraint networks to propagate data throughout a set of equations without a specific ordering is relevant and useful in the design of laminates. To test this theory, a program known as the Composite Laminate Design Advisor (CLDA) was written using a constraint satisfaction system.
