In the past decade, increasing interest in equity issues resulted in new methodologies in the
area of operations research. This paper deals with the concept of equitably efficient …

We consider a location problem where a planner has to decide where to open facilities
which have to be reached by customers at their own cost. The planner has two objectives …

While making location decisions, the distribution of distances (outcomes) among the service
recipients (clients) is an important issue. In order to comply with the minimization of …

We consider an uncapacitated location problem where p facilities have to be located in
order to serve a given set of customers, and we assume that a customer requesting for a …

Equity is an important consideration in public services such as Emergency Medical Service
(EMS) systems. In such systems not only equitability but also performance depends on the …

We consider single facility location problems with equity measures, defined on networks.
The models discussed are, the variance, the sum of weighted absolute deviations, the …

In location problems for the public sector such as emergency medical service (EMS)
systems, the issue of equity is an important factor for facility design. Several measures have …

In this paper, a multi-objective particle swarm optimization algorithm is used to obtain the
Pareto frontiers of the different commensurable and conflicting objective functions for fuzzy …

We propose models to investigate effectiveness–equity tradeoffs in tree network facility
location problems. We use the commonly used median objective as a measure of …

There have been a number of discrete facility location models that deal with the use of some
equality measures of the distances between the facility and the users. They have been used …
