NOTE: there will be no lecture on Tuesday 14th October.
You can find some useful mathematical background material for the course here.
If you are not already comfortable with all these concepts you will need to put in some additional work to begin with to get up to speed. This material will be assumed.
Lectures Slides Modelling and Simulation Lecture 1 Operational Laws Lecture 2 Constructing and Solving Markov Processes Lecture 3 More Complex Markov Processes Lecture 4 Queueing Networks Lecture 5 Solving Queueing Models Lecture 6 Stochastic Petri Nets Lecture 7 More about GSPN Models Lecture 8 Using a GSPN for Performance Evaluation Lecture 9 PEPA Lecture 10 The PEPA Plug-in for Eclipse PEPA Case Study: Rap Genius on Heroku
Over the course we will encounter a number of different approaches to constructing performance models and software tools to support their use. Example models will be made available here and students are encouraged to use the examples to gain a deeper understanding of both the modelling styles and the software tools.

PIPE (Platform Independent Petri net Editor) is an open source, platform
independent tool used of the creation and analysis of Petri Nets, and some
of their extension, developed at Imperial College. It is implemented in Java
and has a graphical user interface, which makes it very straightforward to use.
The most recent version is PIPEv4.3.0 and it is available for download from
Once you have unpacked the directory/folder PIPEv4.3.0, enter that directory and issue the command ./launch.sh or .\launch.bat according to your operating system, to launch the PIPE tool.
There is a short movie here which may help you with installing the PEPA Plug-in for Eclipse. You will find the plug-in and further instructions at http://www.dcs.ed.ac.uk/pepa/tools/plugin/download.html.
The summative feedback for the course will be two pieces of assessed coursework.
There are no tutorials for this course but individual assistance is available: mail me and make an appointment Jane.Hillston@ed.ac.uk.
Individual personalised feedback will be written on your submission and a specimen solution will be provided.
Formative feedback will be provided throughout the course in a variety of forms:
There is no textbook for this course but extensive notes will be given.
If you want further information on the topics covered you may consider the books in the course booklist.
