Abstract:
Group screening can lead to a tremendous reduction in number of tests and costs, and therefore has attracted considerable attention in literature. For several decades, a model from Robert Dorfman was the de facto standard to determine the optimal group size. However, more recently, it has been pointed out that the model from Dorfman is rather static, i.e., a predetermined large number of items has to be screened, whereas in reality the context is rather dynamic: items arrive at random moments in time, in groups of different and random size. In this paper, we investigate to what extent the optimal group size in the static model from Dorfman remains efficient in a dynamic context. This is of vital importance for practitioners, as the model from Dorfman was the de facto standard for several decades and thus has to be validated. On top of that, even though dynamic models exist nowadays, these are much harder to implement and require a time-consuming processing time, due to the numerical work that is involved, such as repeatedly calculating zeroes of functions and solving sets of equations.
