  • Plenary Talk : Stochastic programming with mixed-integer variables

Stochastic programming studies models and solution methods to support decision making under uncertainty, thus aiming to explicitly cope with an important characteristic of many real world problems. Instead of assuming that future parameters are known, it is assumed that only probabilistic information is available at the time that decisions have to be taken.

We will give an overview of some of the main models studied in stochastic programming. Of particular interest are models involving integer (binary) variables as required for modeling many practical problems. For example, deciding on the location of a distribution center could be modeled as an integer stochastic program. However, solving such models is challenging since they combine the difficulties met in both stochastic and integer programming. Some recent developments in this active research area will be discussed.

Abstract

The logistics activities in an organisation include freight transport, storage, inventory management, materials handling and all the related information processing. The main aim of logistics is to design and operate these activities in a way that meets service requirements at minimum cost. In the past, this cost was often defined in purely monetary terms. In Green Logistics, the environmental and social costs must also be taken into account. These costs may include the effects of climate change, air pollution, noise, vibration and accidents.

In 2006, the Engineering and Physical Sciences Research Council (EPSRC), sponsored a research project, completed in 2010, to examine ways of achieving a more sustainable balance between economic, environmental and social objectives in the field of logistics. The project involved researchers from universities at Cardiff, Heriot-Watt, Lancaster, Leeds, Southampton and Westminster. The presentation will give an overview of some of the results from this project and outline scope for further modelling.

Issues to be discussed include:

What changes would be needed to road transport distribution to meet CO2 emissions targets?
Is on-line shopping greener?
What is the effectiveness of container train services?
How can waste be collected efficiently?
Can consideration of traffic congestion in vehicle routing reduce CO2 emissions?
