Abstract:
This paper is about a new technique to find Petri net models for a clock pulse spotted simulation of processes in logistics and production. These models can be used to observe the raising and discharging of stocks in production in order to identify bottlenecks, to observe differences of push and pull strategies on the valued stocks, and to decide on strategic changes. For this, however, significant preliminary tasks had to be conducted first which are also objective of this paper: a novel, web-based Petri net modeling and simulation environment called Process-Simulation.Center (P-S.C) has been developed since existing tools are not at the least able to handle such sophisticated models. And at the moment the tool worked properly, different approaches to model the described situation had to be compared. A teaching laboratory for logistics has been chosen as a sample application. The simulation now helps students to scale up their personal observations in the lab with respect to time, amount and value. This paper explains the situation in the laboratory, the new features of the P-S.C that enable the modeling of these processes, and the finding of the model itself. Finally, its development led to another, different approach to describe the teaching processes by a so called event triggered simulation that is shortly considered in contrast.
