The paper “The Bicriterion Multi Modal Assignment Problem: Introduction, Analysis, and Experimental Results” have been accepted for publication in INFORMS Journal on Computing and is now avaliable online.
July 14-18, 2008 I participated in IBC – the XXIVth International Biometric Conference in Dublin. Here I presented a poster “Embedding a State Space Model into a Markov Decision Process”. Afterwards I spend a few days enjoying Dublin.
The paper “An algorithm for ranking assignments using reoptimization” are now available online at C&OR.
The first of March my research group Statistics and Decision Analysis was merged with the research group Bioinformatics and Statistical Genetics. The name of the new group is Bioinformatics, Genetics and Statistics. The reason for the merge is for instance a greater flexibility in teaching and a closer collaboration around bioinformatics.
Yesterday I participated in a theme day about Herd Navigator which is the commercial product developed under the Biosens I project. Herd Navigator makes it possible to provide decision support of individual cows in terms of reproduction, health and feeding, giving the farmer a financial benefit per cow per year. The herd manager gains a better overview of the condition of the herd and can take action early against diseases and at the right time for reproduction. Earlier intervention means savings in time and costs and also ensures optimal reproduction control. The product uses a combination of biosensors, IT, statistics and OR techniques. The product won the Agromek prize. The partners are Dansk Kvæg, DeLaval and FOSS.
After the Faculty of Agricultural Sciences joined University of Aarhus there have been much activity developing our new bachelor and master degrees. The last months I have been involved in creating new courses in statistics and management science. The degrees will be offered from the autumn of 2008. Their contents are now in the final stages of preparation.
The term Operations Research is not so well-known in Denmark. I found this video with Vijay Mehrotra about the subject that give a good description and why managers should care about OR.
The last days 5-9 November I have been visiting Professor Anders Ringgaard Kristensen at KU Life. We have been working on a package in R “MDP” which will provide tools for solving Markov decision processes and their extension multi-level hirarchic Markov decision processes. The package will be based on a solver made by Anders in Java.
The paper “Bicriterion shortest paths in stochastic time-dependent networks” have been accepted for publication in Lecture Notes in Economics and Mathematical Systems.
