The personnel task scheduling problem is a subject of commercial interest which has been investigated since the 1950s … scheduling problem (SMPTSP). To illustrate the increased efficacy of the proposed algorithm over an existing algorithm …, computational experiments are performed on a test problem set with characteristics motivated by employee scheduling applications …

We investigate two scheduling problems. The first is scheduling with agreements (SWA) that consists in scheduling a set … machines with two fixed processing times. The second problem is the so-called resource-constrained scheduling. We prove that … SWA is polynomially equivalent to a special case of the resource-constrained scheduling and deduce new complexity results …

In this paper we consider a production process at operative level on m identical parallel machines, which are subject to stochastic machine failures. To avoid long downtime of the machines, caused by unexpected failures, preventive maintenance activities are planned and conducted, but if a...

The paper deals with the two most important mathematical models for sequencing products on a mixed-model assembly line in order to minimize work overload the mixed-model sequencing (MMS) model and the car sequencing (CS) model. Although both models follow the same underlying objective, only MMS...

A network needs to be constructed by a server (construction crew) that has a constant construction speed which is incomparably slower than the server’s travel speed within the already constructed part of the network. A vertex is recovered when it becomes connected to the depot by an already...

In this paper we consider timetable design at a European freight railway operator. The timetable is designed by choosing the time of service for customer unit train demands among a set of discrete points. These discrete points are all found within the a time-window. The objective of the model is...
