Last year was the 25th anniversary of two seminal transportation hub location publications,
which appeared in 1986 in Transportation Science and Geographical Analysis. Though …

The Steiner tree problem (STP) in graphs is one of the most studied problems in
combinatorial optimization. Since its inception in 1970, numerous articles published in the …

The increasing concern over global warming has led to the rapid development of the electric
vehicle industry. Electric vehicles (EVs) have the potential to reduce the greenhouse effect …

This article comprises the first theoretical and computational study on mixed integer
programming (MIP) models for the connected facility location problem (ConFL). ConFL …

We consider a fixed-charge capacitated relay network design problem (CRNDP), which has
widespread applications in the design of telecommunication and transportation networks …

Because of the limited range of alternative fuel vehicles (AFVs) and the sparsity of the
available alternative refueling stations (AFSs), AFV drivers cooperatively deviate from their …

We introduce a practically important and theoretically challenging problem: finding the
minimum cost path for PHEVs in a road network with refueling and charging stations. We …

We present exact algorithms for solving the minimum connected dominating set problem in
an undirected graph. The algorithms are based on two approaches: a Benders …

Placement of regenerators in optical networks has attracted the attention of recent research
works in optical networks. In this problem we are given a network, with an underlying …

We consider a scheduling problem in which a bounded number of jobs can be processed
simultaneously by a single machine. The input is a set of n jobs J={J1,…, Jn}. Each job, Jj, is …
