In a recent series of papers a new type of objective function in location theory, called
ordered median function, has been introduced and analyzed. This objective function unifies …

One of the classics in the field of Location Science is the book on the theory of industrial
location by Weber (1909). Weber used a simple construct comprised of a 3-point triangle to …

When a group of decision-makers faces the problem of ranking a set of decision alternatives,
it is usually necessary to reach a consensus among the group members on ranking …

Given are a finite set of points P and a compact polygonal set S in R2. The problem is to
locate two new facilities in S, maximizing the minimum of all weighted distances between the …

In this paper we consider several different problems of placing an obnoxious facility on
geometric networks. In particular, our main results show how to obtain efficient polynomial …

Facility location problems are concerned with the location of one or more facilities in a way
that optimizes a certain objective such as minimizing transportation cost, providing equitable …

In this paper, we introduce and study the problem of facility location along with the notion of
'social distancing'. The input to the problem is the road network of a city where the nodes are …

We consider single facility location problems defined on rectilinear spaces and spaces
induced by tree networks. We focus on discrete cases, where the facility is restricted to be in …

In this paper, we present a novel algorithm and efficient data structure for anomaly detection
based on temporal data. Time-series data are represented by a sequence of symbolic time …

An obnoxious facility is to be located inside a polygonal region of the plane, maximizing the
sum of the k smallest weighted Euclidean distances to n given points, each protected by …
