Considers the application of returnable containers as an example of
reverse logistics. A returnable container is a type of secondary
packaging that can be used several times in the same form, in contrast
with traditional cardboard boxes. For this equipment to be used, a
system for the return logistics of the containers should be available:
this system should guarantee that the containers are transported from
the recipients to the next senders, and that they are cleaned and
maintained, if necessary. Outlines several ways in which the return of
these containers can be organized. Also includes a case study involving
the design of such a return logistic system in The Netherlands. Also
describes a quantitative model that can be used to support the related
planning process.

In this paper we give an overview of state‐of‐the‐art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to solve them. We do not only consider classical, well‐known topics such as timetabling, rolling stock scheduling and crew scheduling, but we also discuss some recently developed topics such as shunting and reliability of timetables.Finally, we focus on several practical aspects for each of these problems at the largest Dutch railway operator, NS Reizigers.
