Strategic optimization of water reuse in wafer fabs via multi-constraint linear programming technique

Mathematical Model of Unsteady Groundwater Flow Through Aquifers and Calibration Via a Non-Linear Optimization Technique

In this study, the general partial differential equation of unsteady groundwater flow through non-homogeneous and anisotropic aquifer was solved by the fully implicit finite difference method with control volume approach. The calibration of permeability and storage coefficients as model parameters was performed by a transformation technique and application of Powell's non-linear optimization me...

On Integrating Constraint Propagation and Linear Programming for Combinatorial Optimization

Linear programming and constraint propagation are complementary techniques with the potential for in tegration to bene t the solution of combinatorial op timization problems Attempts to combine them have mainly focused on incorporating either technique into the framework of the other traditional models have been left intact We argue that a rethinking of our modeling traditions is necessary to a...
