Condition-event Petri nets are a means to model technical, social, and natural processes and organizations in order to unterstand their behavior, to identify bottlenecks and resource shortcomings, and to propose appropriate changes. PETRI-HELP is an intelligent problem solving environment that supports this modelling activity. Since there is no clear-cut domain theory of Petri net modelling, net design processes can be supported only in limited ways. In order to overcome this situation, a cognitive model of problem solving, knowledge acquisition, and knowledge modification was developed which is an instance of a general theoretical framework. The main results of the model can be summarized in three hypotheses: Problem solving and knowledge acquisition in a domain without a worked-out domain theory 1. consists of i) applying weak heuristics and acquiring new knowledge in response to impasses, and ii) knowledge optimization 2. involves few simple, fairly general heuristics which seem to be important also to other design and configuration domains 3. can be supported by giving feedback and help information sensitive and adaptive to the actual needs of the learner, if appropriate behavioral indicators are provided.
