In this paper we investigate a model where travel time is not necessarily proportional to the distance. Every trip starts at speed zero, then the vehicle accelerates to a cruising speed, stays at the cruising speed for a portion of the trip and then decelerates back to a speed of zero. We define...

Rejoinder to the previous note (Erlenkotter, D. 1974. Note--Dynamic facility location and simple network models. Management Sci. 20 (9) 1311.).

A dynamic or multiperiod location-allocation formulation is developed from the static problem of locating G facilities among M possible sites to serve N demand points. This dynamic model provides a tool for analyzing tradeoffs among present values of static distribution costs in each period and...

This note deals with the one-dimensional facility location model in which the weights, which can represent either demand volumes or demands and costs combined, are known only probabilistically. The demand points themselves, or at least the "feeder" routes to the demand points, for the facility...
