Abstract: Preemptive goal programming is applied to the real‐time, daily operation of multiple‐purpose, multiple‐reservoir systems. A significant advantage of the goal programming approach is that it may be based on physical operating ...

Abstract: Existence of several problems associated with the optimization of real‐time operations of reservoir systems is demonstrated. The first problem presented is due to the use of imperfect streamflow (inflow to the reservoir) ...

Abstract: Aggregate blending models that incorporate the optimization of two objectives with their priority levels are presented. The two objectives include the minimization of the mean deviation (or mean absolute deviation) from ...

Abstract: An optimization model of aggregate blending is presented that considers gradation, cost, and design requirements and is applicable to the blending of any number of aggregates. The model is formulated as a quadratic programming ...
