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.
