Robust supplier selection problem, in a scenario-based approach has been proposed, when the demand and exchange rates are subject to uncertainties. First, a deterministic multi-objective mixed integer linear programming is developed; then, the robust counterpart of the proposed mixed integer linear programming is presented using the recent extension in robust optimization theory. We discuss dec...

We do not feel that the linear programming user’s most pressing need over the next few years is for a new optimizer that runs twice as fast on a machine that costs half as much (although this will probably happen). Cost of optimization is just not the dominant barrier to LP model implementation. The process required to manage the data, formulate and build the model, report on and analyze the re...

A three-step algorithm is presented for discrete gate sizing problem of delay/area optimization under double-sided timing constraints. The problem is rst formulated as a linear program. The solution to the linear program is then mapped onto a permissible set. Using this permissible set, the gate sizes are adjusted to satisfy the delay lower and upper bounds simultaneously.
