In 1960, Ailsa Land and Alison Doig published the first linear programming-based branch-and-bound algorithm for the solution of mixed integer linear progra...

The Network Design Problem with Vulnerability Constraints and Probabilistic Edge Reliability (NDPVC-PER) is an extension of the NDPVC obtained by additionall...

In July 2022, I received the EURO Gold medal at the 32nd EURO Conference held in Espoo, Finland. On this occasion I was asked to deliver a 30-minute presenta...

In e-commerce warehouses, online retailers increase their efficiency by using a mixed-shelves (or scattered storage) concept, where unit loads are purposeful...

Metros and other rapid transit systems increase the mobility of urban populations while decreasing congestion and pollution. There are now 187 cities with a ...

This paper introduces two classes of location problems with interconnected facilities. These problems differ from classical location problems in the sense ...

Electric commercial vehicles (ECVs) are gaining importance as they are seen to provide a sustainable mean of transportation. However, practitioners still see...

This paper reviews the literature on vehicle routing problems and location-routing problems with intermediate stops. Besides providing concise paper excerpts...

The purpose of this paper is to develop a fast heuristic called FastCARP for the solution of very large-scale capacitated arc routing problems, with or witho...

Location-routing problems (LRPs) with intra-route facilities have recently gained the attention of researchers and practitioners. Intra-route facilities are ...

The aim of this paper is to computationally compare several algorithms for the Minimum Cost Perfect Matching Problem on an undirected graph. Our work is moti...

This paper introduces the pickup and delivery problem with time windows and handling operations. In this problem, the loading compartment of a vehicle is mod...

We model and solve the problem of sequencing a set of jobs with specified processing times and tool requirements on a set of identical parallel machines. D...

This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and multiple stacks. Each stack is rear-loade...

The Tube Challenge consists of visiting all stations of the London Underground in the least possible time. The competition started in 1959 and the current r...

In this article, we solve the pickup and delivery problem with time windows and last-in-first-out (LIFO) loading. LIFO loading minimizes handling while unloa...

This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and last-in-first-out (LIFO) loading constr...

Scheduling often plays an important role in vehicle routing. This paper describes several applications in which the author has been involved in recent years...
