In the course of modeling administrative type business processes one of the crucial objective is to meet the criteria namely to produce the relevant and adequate documents with the help of the necessary input documents and resources. A further important goal is, however, to examine the dynamic behavior of the constructed model and to reveal resource constraints and bottlenecks during the operation of the system. Parallel to several existing models, the p-graph-based workflow model as well as business process modeling have been introduced in our earlier papers. One of their big advantages is the systematic generation of the optimal model structure. This paper presents a possible extension, namely the extension capable of the examination of the dynamic behavior of this model. The model originally is represented by p-graph. The extended model includes a special descriptor linked to each element of the p-graph, which stores the features of the given element. We precisely define each single characteristic of the document descriptor, the activity descriptor and the resource descriptor and even their interpretation in the system. As an extension of the already used visual notation we introduce animation in operation, which is a useful supplement in system examination. Based on this, congestions and scarcity can be identified in the system. The rate of these features can be calculated and precisely determined during the simulation for the purpose of effective evaluation of the operation. For the precise execution of administrative tasks it is necessary to pair the input documents, furthermore, the relevant legal regulations must be taken into account. The operation of activities in the simulation of the dynamic behavior is separately discussed, whose algorithm is defined in this paper. This kind of extension of the so far used p-graph-based business process model can be beneficially applied in the course of the analysis of the dynamic behavior of a system. Based on these analyses our models can be further optimized.
