), business processes (enterprise architecture, policy and procedures, logistics, project management, etc.
The structure of a process system, or its architecture, can be viewed as a dualistic relationship of its infrastructure and suprastructure.
As one traverses the process architecture from one level of abstraction to the next, infrastructure becomes the basis for suprastructure and vice versa as one looks within a system or without.
White-box requirements, such as engineering rules, programming syntax, etc., come from the process system's infrastructure.
Process systems are a dualistic phenomenon of change/no-change or form/transform and as such, are well-suited to being modeled by the bipartite Petri nets modeling system and in particular, process-class dualistic Petri nets where processes can be simulated in real time and space and studied hierarchically.
