Abstract

An important step in model building that has been given little attention is the formulation of consistent initial state – and parameter vectors. In this paper we motivate that indeed this step is error prone. Improvement is obtained by incorporating in the model ‘static relations ’ that limit the freedom in choosing values for the initial state – and parameter vectors. Such relations should be implemented by means of constraints. A prototype realisation in 20-sim is described
