When conducting appraisal and scheme testing, it is important to be confident that the change you observe between scenarios is caused by the scheme test rather than noise.  It has often been said that dynamic models cannot converge. This statement is made as if it is obvious that this is the case. In this presentation, we will look at why it is difficult to achieve convergence in dynamic assignment and how convergence can be achieved through a change in methodology and careful decision making in design.
