Process Modelling


Admission requirements

Not applicable


We have established in the course ICT enabled process innovation that process oriented thinking and the (re)engineering of business processes can change the way that companies carry out their business and improve their performance. In this course Process modelling we will focus on the process engineer, as an agent of this change, and provide him or her with a scientifically sound set of engineering methods and tools. During the course, the participants will become familiar with the look-and-feel of one informal approach to business process modelling, based on BPMN and one formal approach, based on Petri nets, and gain hands-on experience with the tools supporting these approaches in a realistic case study. Finally we will provide an overview of recent developments in the field of process mining and automated process discovery.

Course objectives

By the end of this course the student should :

  • be able to create business process models with BPMN and understand its relationship with more formal approaches

  • understand the formal approach to business process modelling and analysis based on Petri nets

  • have a basic understanding of the theory behind Petri nets

  • be able to create a Petri net model in a realistic case study

  • be able to analyze that model to establish the properties of the process design even before implementation, i.e. on the “drawing board”

  • be familiar with Woped and CPN Tools, both tools for creating and analyzing Petri nets.

  • have a basic understanding of methods for automated process discovery

  • be familiar with some of the more commonly used tools for process mining and automated process discovery


You will find the timetables for all courses and degree programmes of Leiden University in the tool MyTimetable (login). Any teaching activities that you have sucessfully registered for in MyStudyMap will automatically be displayed in MyTimeTable. Any timetables that you add manually, will be saved and automatically displayed the next time you sign in.

MyTimetable allows you to integrate your timetable with your calendar apps such as Outlook, Google Calendar, Apple Calendar and other calendar apps on your smartphone. Any timetable changes will be automatically synced with your calendar. If you wish, you can also receive an email notification of the change. You can turn notifications on in ‘Settings’ (after login).

For more information, watch the video or go the the 'help-page' in MyTimetable. Please note: Joint Degree students Leiden/Delft have to merge their two different timetables into one. This video explains how to do this.

Mode of instruction

Every week: 2 hours lecture and 1 hour exercise class per session

Assessment method

The final grade is a weighted average of the grades for the written exam and the exercise class. The grade for the written exam must be at least 5.0. The weighting factors are as follows:

  • Exercise class : 30 %

  • Written exam : 70 %
    Exercise class will be graded based on:

  • presence during class

  • results on selected exercises and assignments from the course syllabus

  • a final report of the running case, that must be handed in before the end of the course.

The teacher will inform the students how the inspection of and follow-up discussion of the exams will take place.

Reading list

We will use the following books:
1. Modelling Business Processes – A Petri Net-Oriented Approach, by W.M.P van der Aalst and C Stahl (MIT Press, 2011)
2. BPMN Method and Style by Bruce Silver (Cody-Cassiy Press, 2011)

Other materials like a syllabus and lecture slides will be provided during the course.


Every student has to register for courses with the new enrollment tool MyStudyMap. Please see this page for more information.

Please note that it is compulsory to both preregister and confirm your participation for every exam and retake. Not being registered for a course means that you are not allowed to participate in the final exam of the course. Confirming your exam participation is possible until ten days before the exam.
