All research carried out has been within the area of model based decision support in animal production with main emphasis on recurrent decision problems as for instance the animal replacement problem, where Markov decision programming techniques have been developed, modified and applied as a framework for management support in dairy cattle and pig production. Main results include:
Development of the notion of a hierarchic Markov process in order to circumvent the well known dimensionality problem of dynamic programming.
Introduction of a new criterion of optimality in order to optimize replacement policies under the milk quota system of the European Union.
Development of methods for representation of animal traits using Bayesian updating techniques.
Development of a framework for dealing with herd constraints as for instance a limited supply of heifers for replacement.
Simultaneous optimization of decisions at the tactical and operational level using multi-level hierarchical Markov processes. A software system is available.
Various applications of multi-level hierarchical Markov processes in pig production, steer production and grass ley management.
Dynamic simulation of a scavenging chicken flock.
Since 1991, the research has been carried out as part of DINA.
Herd management has been taught at undergraduate level since 1986 and post graduate level since 1991. Integrated basic courses (including management, feeding and housing) are given in dairy production and pig production, respectively. An advanced course in herd management is taught separately.
