This paper presents a general mixed-norm minisum problem for locating a single facility in continuous space. It is assumed that several transportation modes exist between the new facility and a given set of fixed points (the customers), each mode bei

The weighted lp or lk,p norm is used to model travel distances in road networks. The parameters k and p are computed from a sample of actual road distances taken from the geographical area of interest. During the computation, a goodness-of-fit criter

We devise a new method to calculate the confidence intervals for estimated actual distances. For that purpose, we first develop a prediction error related random variable which is both homoscedastic and normally distributed, and then we use this rand

We consider the p-norm multi-facility minisum location problem with linear and distance constraints, and develop the Lagrangian dual formulation for this problem. The model that we consider represents the most general location model in which the dual

Distance functions are employed to estimate actual distances in a transportation network. The l bp -norm, which is a weighted sum of order p, is a generalization of the weighted l p -norm, a well-known distance-predicting function. We derive some mat

The weighted sum of order p , the l bp -norm, is a generalization of the well-known l p -norm used in predicting distances in a transportation network. The properties of the directional bias function and the unit balls for the l bp -norm are of theor

Distance predicting functions may be used in a variety of applications for estimating travel distances between points. To evaluate the accuracy of a distance predicting function and to determine its parameters, a goodness-of-fit criteria is employed.

A generalized form of the Fermat-Weber problem requires finding a point in R N to minimize a sum of nondecreasing functions of distances to m given points. In this paper, local convexity properties are investigated for the generalized problem. Suffic

Many heuristic algorithms for solving geometric traveller problems utilize the extreme points of the convex hull of the given points to provide an initial partial tour. These heuristics are supported by the property that an optimal lour visits the ex

In this paper we define and analyze a class of two-dimensional location-allocation problems that can be solved with a one-dimensional dynamic programming algorithm. We define a criterion that must be satisfied in order that a problem can be classifie
