The theory of constraints is an approach to production planning and control that emphasizes on the constraints to increase throughput by effectively managing constraint resources. One application in theory of constraints is product mix decision. Product mix influences the performance measures in multi-product manufacturing system. This paper presents an alternative approach by using of goal pro...

We propose a variant of the Hierarchical Constraint Logic Programming (HCLP) scheme of Borning, Wilson, and others. We consider compositionality and incre-mentality in Constraint Logic Programming, introduce HCLP, and present Wilson's proof 11] that it is non-compositional and non-monotonic. We deene a scheme for composing together solutions to individual hierarchies and show that hierarchy com...

In this article we review how constraint theory can be applied to proteins to give useful information about the rigid and flexible regions. This approach includes all the constraints in a biomolecule that are important at room temperature. A rigid region decomposition determines the rigid regions (both stressed and unstressed) and the flexible regions that separate them. Such a rigid region dec...
