We develop a method to locate bifurcations in time delay systems with a potentially high‐dimensional parameter space. It is based on the feedback loop breaking approach that we developed and applied earlier for bifurcation search in ordinary differential equations. The method is particularly suited for the analysis of biological networks, for example to determine which parameters are relevant for complex dynamical behavior in such networks. To illustrate the benefits that this approach yields for biological network analysis, we apply it to study the effect of parameter variations on oscillations in a model of the MAP kinase cascade with a time delay.
