Just finished my last Management Science lecture for this semester. This is the first time I theach this introductory course to Business Students. Topics are linear and integer programming, goal programming, simulation and network models.

En populærvidenskabelig artikel er netop udkommet i OrBit omkring min MDP model for udskiftning af malkekvæg. “Det optimale udskiftningstidspunkt for en malkeko“, L.R. Nielsen and E. Jørgensen, OrBit, 17, 14-16 (2010).
The research paper “Quantifying walking and standing behaviour of dairy cows using a moving average based on output from an accelerometer” have been accepted for publication in Applied Animal Behaviour Science. It presents research from my time at DJF where we use a moving average to predict walking and standing behaviour of dairy cows.
I am currently participating in the EURO conference in Lisbon. I gave a talk about “Optimal replacement policies for dairy cows” yesterday. The conference has approximately 2300 participants and many streams.
I have written a small note about mapping a multidimensional index into a unique id. An unique id might be useful e.g. when having multiple state variables in an Markov decision process. Here each state at a stage may be identified using the id.
The from February to May this year I have been teaching in “Seminar in Business Studies” a bachelor course (HA – 4. semester). The course represents a teaching and form of learning where a group of 12 students with one or more teachers discusses selected issues and problems in management science. First the student should write a 10 page report on a specific subject. The report should provide the possibility of in-depth studies of theories, models and methods in management science. While writing the report he can use the assigned advisor for at most 1.5 hours. Second the student, 2 weeks after delivering the report, should give a 10 minutes presentation about their report. Afterwards there is time for 30 minutes of discussion and last 5 minutes for giving a grade. I was assigned 59 students in 6 groups. In 4 of the groups I was the only teacher. In […]
Den 16. marts deltog jeg i kursuset “Vejledning af større studenteropgaver – bachelorprojekt og kandidatafhandling”. Det giver et hurtig overblik over hvilke redskaber man kan bruge i sin vejledning og kan stærkt anbefales.
Two of my papers have been accepted for publication. “Optimal Replacement Policies for Dairy Cows Based on Daily Yield Measurements” have been published in Journal of Dairy Scienc. Abstract: Markov decision processes (MDP) with finite state and action space have often been used to model sequential decision making over time in dairy herds. However, the length of each stage has been at least 1 mo, resulting in models that do not support decisions on a daily basis. The present paper describes the first step of developing an MDP model that can be integrated into a modern herd management system. A hierarchical MDP was formulated for the dairy cow replacement problem with stage lengths of 1 d. It can be used to assist the farmer in replacement decisions on a daily basis and is based on daily milk yield measurements that are available in modern milking systems. Bayesian updating was used […]
