English abstract:
Introduction The MMT system (MMT stands for Mathematics, Modelling and Tools) was developed as an
environment to support e-learning in many ways. The MMT server consists of a huge amount of examples in
mathematics as well as modelling and simulation which is constantly increasing.
On the one hand the MMT is used in lectures for students of electrical engineering and geodesy and geomatics
engineering by showing examples in Linear Algebra and Analysis. Additionally to the demonstration in the lectures
the students get accounts for the MMT to have access to the corresponding examples. This way they are able to
train their knowledge and understanding of the current subject by experimenting on theMMTserver and comparing
the results given by MMT with their own ones.
In lectures about modelling and simulation, the MMT environment is used not only to show results of different
modelling approaches but also to give insight to the models itself by showing the underlying source codes. These
can be downloaded and modified on the studentīs own computer, so beginners in modelling can take proved and
validated models as a starting point and alter them to gain their own model without having to build a whole
complicated model on their own. The examples shown in those lectures are further used in exams via another
e-learning platform, e.g. TUWEL, the Moodle-based e-learning system of the Vienna University of Technology.
As mentioned above, the amount of examples on the MMT server is constantly increasing. Apart from models
particularly developed for certain educational needs by programmers of the MMath-EL Group, models created by
students during projects, bachelor or diploma theses are reviewed, validated and further adjusted and linked to the
MMT system.
Recent Developments Recently the MMT environment has successfully been updated to enable examples accessing
several MATLAB functions as well as Simulink models. Thus it is possible to install models of more or
less any complexity at the MMT interface. The various m-files just need to be called from a certain MATLAB
function to begin with.
Simulink models are called by a MATLAB function consisting only of the extraction of the input values of the
MMT server and the execution of the Simulink model. By having enabled examples using Simulink models,
teaching modelling and simulation can now focus also on the method of Physical Modelling.
Summary and Outlook Currently in the course of a collaboration of the Vienna University of Technology and
the University of Ljubljana complex models of linear an non-linear tank systems and petrinets are included into
the MMT system. In this way the different modelling approaches of both universities can be accessed by students
in Ljubljana as well as in Vienna, what will additionally extend their modelling skills.
Recently the focus of new MMT models was laid on discrete modelling for the usage of the MMT system in
lectures for students of business informatics. Contrary to most of the other examples implemented on the MMT
server which are dynamic systems described by ordinary differential equations, discrete models are described by
systems of difference equations.
Further goals are the inclusion of other programming languages like Java and Octave into the MMT environment.
This will enlarge the possibilities of teaching modelling and simulation via MMT by a significant amount.
