According to one embodiment of the invention, a method for integrated decision support is disclosed. The method includes receiving decision inputs. The method also includes converting the received decision inputs to graph representations and mathematical representations. The method further includes decomposing the converted decision inputs to sub-problems. The method further includes detecting strongly-connected components associated with the sub-problems. The strongly-connected components represent the sub-problems that are coupled. The method further includes solving the sub-problems.

Integrated decision support framework for collaborative product development

A method and system for applying constraints to a wireframe chain of curves for Computer-Aided Design (CAD) is disclosed, whereby a geometric constraint network can be expanded to include chains of curves as types of wireframe entities. As such, a chain of curves can be represented as one composite curve. As a result, a constraint solver can generate and/or maintain any constraint on a chain of curves, which enables the constraints to be solved while moving along the curves independently from the chain's geometry and topology changes.
