Abstract. Asbru is a complex formal language developed to represent clinical guidelines and protocols which are time- and processoriented. To facilitate and support the modeling in Asbru methods and tools are required. In this paper, we provide a systematic analysis of the various plan components and their temporal interdependences (written in Asbru) to infer heuristics for our methods and tools. We develop different forms of representations to display flows in Asbru to simplify the modeling process.
