Online optimisation for ambulance routing in disaster response with partial or no information on victim conditions (2023)
Journal Article

In response to mass casualty incidents, medical aid must be provided to numerous victims synchronously under challenging circumstances including uncertainty about the condition of victims. Therefore, it is essential to have decision support tools whi... Read More about Online optimisation for ambulance routing in disaster response with partial or no information on victim conditions.

Minimizing total weighted latency in home healthcare routing and scheduling with patient prioritization (2023)
Journal Article

We study a home healthcare routing and scheduling problem, where multiple healthcare service provider teams should visit a given set of patients at their homes. The problem involves assigning each patient to a team and generating the routes of the te...

Integrated and Coordinated Relief Logistics and Road Recovery Planning Problem (2022)
Journal Article

Sudden onset disasters can block roads and hinder relief logistics. With the objective of facilitating access to critical locations in the disaster-stricken area, we propose a new mathematical model that determines the schedule and routes of a relief...

A bi-objective blood supply chain model under uncertain donation, demand, capacity and cost: a robust possibilistic-necessity approach (2022)
Journal Article

This paper addresses a multi-objective blood supply chain network design, considering economic and environmental aspects. The objective of this model is to simultaneously minimize a blood supply chain operational cost and its logistical carbon footpr...

Electric vehicle routing problem with flexible deliveries (2022)
Journal Article

Growing concerns about the climate change have forced governments to initiate tighter environmental regulations and tougher emission reduction targets, increasing the interest on electromobility. Logistics operators started employing electric vehicle... Read More about Electric vehicle routing problem with flexible deliveries.

A Review of Applications of Operational Research in Healthcare Coordination in Disaster Management (2021)
Journal Article

Many disasters that have happened in the last decades, including the latest COVID-19 pandemic, have caused a shortage of healthcare resources and change in healthcare operations. Given these impacts, the Operational Research (OR) community has applie... Read More about A Review of Applications of Operational Research in Healthcare Coordination in Disaster Management.

An online optimization approach for post-disaster relief distribution with online blocked edges (2021)
Journal Article

Disasters can disrupt road networks by blocking some of the roads and consequently impeding accessibility to critical locations. In the immediate post-disaster response phase, while the blockage information is yet to be collected, relief distribution... Read More about An online optimization approach for post-disaster relief distribution with online blocked edges.

Routing multiple work teams to minimize latency in post-disaster road network restoration (2021)
Journal Article

After a disaster, often roads are damaged and blocked, hindering accessibility for relief efforts. It is essential to dispatch work teams to restore the blocked roads by clearance or repair operations. With the goal of enabling access between critica... Read More about Routing multiple work teams to minimize latency in post-disaster road network restoration.

Analysis of the sharing economy effect on sustainability in the transportation sector using fuzzy cognitive mapping (2021)
Journal Article

Along with the significant growth of the sharing economy in recent years, its effect on the economy, society, and the environment at the level of governments, academic communities, and researchers has been widely discussed. One of the main debates is... Read More about Analysis of the sharing economy effect on sustainability in the transportation sector using fuzzy cognitive mapping.

A decomposition-based heuristic for a multicrew coordinated road restoration problem (2021)
Journal Article

Natural disasters disrupt the connectivity of road networks by blocking road segments, which impedes efficient distribution of relief materials to the affected area. We study the problem of finding coordinated paths for clearing teams so that the con... Read More about A decomposition-based heuristic for a multicrew coordinated road restoration problem.

Online Failure Diagnosis in Interdependent Networks (2021)
Journal Article

Motivation. In interdependent networks, nodes are connected to each other with respect to their failure dependency relations. As a result of this dependency, a failure in one of the nodes of one of the networks within a system of several interdepende... Read More about Online Failure Diagnosis in Interdependent Networks.

Online routing and scheduling of search-and-rescue teams (2020)
Journal Article

We study how to allocate and route search-and-rescue teams to areas with trapped victims in a coordinated manner after a disaster. We propose two online strategies for these time-critical decisions considering the uncertainty about the operation time... Read More about Online routing and scheduling of search-and-rescue teams.

Minimizing latency in post-disaster road clearance operations (2019)
Journal Article

After a natural disaster, roads and bridges can be damaged or blocked by debris, causing inaccessibility between critical locations such as hospitals, disaster response centers, shelters and disaster-struck areas. We study the post-disaster road clea... Read More about Minimizing latency in post-disaster road clearance operations.

Multi-vehicle prize collecting arc routing for connectivity problem (2017)
Journal Article

© 2017 Elsevier Ltd For effective disaster response, roads should be cleared or repaired to provide accessibility and relief services to the affected people in shortest time. We study an arc routing problem that aims to regain the connectivity of the... Read More about Multi-vehicle prize collecting arc routing for connectivity problem.

Multi-vehicle synchronized arc routing problem to restore post-disaster network connectivity (2016)
Journal Article

© 2016 Elsevier B.V. After a natural disaster roads can be damaged or blocked by debris, while bridges and viaducts may collapse. This commonly observed hazard causes some road sections to be closed and may even disconnect the road network. In the im...
