Our new paper in the European Journal of Operational Research is now online. Abstract: Constraint programming solvers are known to perform remarkably well for most scheduling problems. However, when comparing the performance of different available solvers, there is usually no clear winner over all relevant problem instances. This gives rise…

Our new paper in Computers & Operations Research is now online. Abstract: We consider a semiconductor final-test scheduling problem that aims at minimizing the total weighted tardiness. In contrast to previous studies on this problem, we explicitly take account of the need to assign human operators to setup operations. We…

Our new paper in the International Journal of Production Research is now online. Abstract: This paper addresses a flexible job shop scheduling problem that takes account of workforce constraints and aims to minimise the makespan. The former constraints ensure that eligible workers that operate the machines and may be heterogeneously…

Our new paper in the European Journal of Operational Research is now online. Abstract: This paper treats the Piggyback Transportation Problem: A large vehicle moves successive batches of small vehicles from a depot to a single launching point. Here, the small vehicles depart toward assigned customers, supply shipments, and return…
