From November 4-7, 2018 we have been participating the annual INFORMS conference, Phoenix, AZ, US. Talks have been interesting and for the first time CORAL joined the job fair to promote open Assistant and Associate Professor positions. The interest was overwhelming and some good candidates were found.

MCDM 2013 in Malaga

From 17-22 June 2013 I have been participating in MCDM 2013 in Malaga. The 22nd International Conference on Multiple Criteria Decision Making. The conference was held in a nice atmosphere and the city can be recommended. I coauthored a talk about the Bicriterion Stochastic Knapsack Problem which is a problem we currently are working on.

EURO Summer Institute 2009 (ESI 2009)

Aim of ESI 2009 is to bring together young scientists with academic experts on OR methods besides the development of applications for Agriculture, Forestry and related industries of the primary sector. Anders Ringgaard Kristensen and I will the first day talk about Markov decision processes (MDPs) for sequential decision problems in agriculture and forestry. First the theory of MDPs will be presented and next I will give an introduction to my new MDP package in R. The files needed for the exercises can be found here.

Kick-off meeting – The Intelligent Farrowing Pen

Today I am participating in a kick-off meeting of the project ‘The intelligent Farrowing Pen’. The four-year project is supported by Højteknologifonden, The Faculty of Agricultural Sciences, Skov A/S and Danish Pig Production. The goal is to develop a system whereby the condition and activity of the animals will be registered. For example, previous studies have shown that the sow is very active in the 24 hours prior to farrowing. She stands up and lies down often and spends time building a nest. This knowledge can be used to predict when she will farrow within a narrow margin. When the system predicts when the sow is expected to farrow, a message is given to the farmer and to a climate control system that ensures that there is more heat in the pen. Not only does this save piglets. It could perhaps also save heating bills in the farrowing barn, which […]
