In this study we investigate the constraint qualifications for the Kuhn-Tucker conditions to hold for an inequality-constrained nonlinear programming problem. We present the qualifications in a consistent manner so that the interrelationships between them are highlighted. This gives rise...

This paper concerns marginal cost pricing in a capacity expansion problem for the electric utility industry. We develop a characterization of equipment selection and marginal capital cost allocation based on an optimal capacity plan, in the context of either a finite, discretely distributed...

In this paper, we address the issues of coal supply and blending pertaining to an electric utility company in Taiwan. Since the fuel used by coal-fired power plants are mainly imported in bulk from overseas sources, the planning of coal shipping and blending is of great economic importance. This...

Without successful large-scale regional evacuations, threats such as hurricanes and wild-fires can cause a large loss of life. In this context, automobiles are oftentimes an essential transportation mode for evacuations, but the ensuing traffic typically overwhelms the roadway capacity and...

Knowledge of motorists' origin-destination (OD) travel information is necessary for a wide range of transportation planning activities. The high cost of manpower and other expenses associated with conventional survey techniques for OD estimation have motivated the development of models that can...

We present a nonproportional-assignment, user-equilibrium motivated, linear programming model for estimating origin-destination (O-D) trip tables from available data on link traffic volumes. The model is designed to determine a traffic equilibrium network flow solution that reproduces the link...
