Contribution of the Budapest University of Technology and Economics Department of Information and Knowledge Management to he USE-eNET Project

Petri Nets provide a highly effective and widely applied tool to build models and simulate them. These are discrete simulation models and the model construction is object oriented thereby providing a tool revealing the systems investigated in a realistic way. These interpreted Petri Nets can describe the operation of real systems in a wide range of fields.

The software and methodology of learning we intend to contribute to the project consists of the following.

  1. A collection of practical problems from a wide range of various fields of applications to be solved by interpreted Petri Net based simulation models will be provided. The tasks to be solved may be used as exercises by the students. In addition to this; a collection of solutions will be given (whether these latter ones will be reachable by the students or only for the teachers is a question of teaching policy).
  2. A software tool where the student can construct a Petri Net graphically on the screen (places, transitions and marking) will be provided.
  3. A possibility enabling the visualization of the token play in a step by step manner will be developed. Thereby the student can judge the correctness of his solution by evaluating the operation of the Petri Net built by her/him.
  4. After sending the solution to the teaching center the teacher may evaluate the correctness and quality of the solution.
  5. Finally a users' manual - to be reached electronically by the students - will be provided.

Summarizing the teaching material will consist of the following modules.

  1. An extendable library of problems to be described by interpreted Petri Net models.
  2. A tool for building Petri Nets by the students which can be displayed graphically on the screen.
  3. A simulator enabling the token play to be controlled in a step by step manner by the student providing simultaneously for displaying the operation of the model.
  4. A software tool providing for the correction and modification of the model by the student. The final model built by the student can be sent to the tutoring center.
  5. As the software system providing for the solution of the above will be located at the teaching center the evaluation of the work of the student by the tutoring center will be possible.
