Abstract - During hospital planning, "flow-chart"-like
depictions of processes (nodes and edges) are often overlaid
over the floor plan of a clinic, in order to model patient
pathways. However, such static definitions may not be
accurate, as patients freely cross from one node into another,
depending on individual treatment. Modelling each possible
sequence of nodes is neither practical nor intelligible. This
means graphical complexity due to overlapping edges. In our
work, we thus present an edgeless process model in which each
node acts as "dispatcher": It carries the logic for choosing a
next node, thus enabling us to omit edges and introduce
dynamic distribution of simulated patients. "Processes" (i.e.
often-perceived sequences of activities) can nevertheless be
inferred in an a posteriori step with an algorithm that will be
presented, utilizing the actual patient pathways as indicator.
Furthermore, the visualization of how processes are generated
out of activity chains by reverse engineering will be discussed
too.
