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 […]

Den 20-22 oktober deltog jeg i DJFs universitetspædagogisk og didaktisk grundkursus der er et kursus ud af tre for at forbedre DJFs forskere I deres nye undervisningsforpligtelse. Kursuset omhandler organisering af undervisning, undervisningsformer samt eksamen og evaluering.
The 9.-11. September I have been participating in OR50 – The UK OR Society’s 50’th conference in York. The conference was held at the University of York’s beautiful lakeside campus. I gave a talk in the agricultural stream about ‘Optimal replacement policies for dairy cows based on daily yield measurements’.
A new working paper “Time-adaptive versus history-adaptive strategies for multicriterion routing in stochastic time-dependent networks” have been published.
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.
