Beginning in the 1960s, techniques from operations research began to be used to generate
political districting plans. A classical example is the integer programming model of Hess et …

When constructing political districting plans, prominent criteria include population balance,
contiguity, and compactness. The compactness of a districting plan, which is often judged by …

Delivery drones are a disruptive technology that is spurring logistics system change, such as
the adoption of urban micro-fulfilment centres (MFCs). In this paper, we develop and …

Location covering models are important spatial analytic methods, and have been widely
applied to different facility siting problems in order to support decision making processes. It …

This paper addresses the multi-period facility location problem during the market expansion
stage, where the decision maker plans to add a certain number of new facilities in each …

Location covering problems are important tools for supporting facility siting decisions in both
the natural and built environment. However, facility workloads often vary significantly using …

Emergency response preparedness requires strategic and operational planning. As natural
disasters, disease outbreaks, and bioterrorism continue to threaten public health and the …

We consider a bi-objective variant of the p-median problem where p facilities must be
located to serve a set of n customers with unitary demand. The considered objectives are …

Specialty medical care is often less accessible for patients from rural, remote or sequestered
areas where the opportunity to access advanced but necessary care is not available locally …

The p-median problem is among the most popular problem types in combinatorial
optimisation with a broad range of application areas from facility location–allocation and …
