Assumed knowledge on:

Elementary mathematics, for instance as taught in the courses MAT-14903 Mathematics 2 and MAT-15003 Mathematics 3.
Specifically you should be acquainted with the following concepts and techniques: functions, differential equations, differentiation and integration.


Systems approaches are widely used in education, research and management to understand, analyse and manage systems with the help of simulation models. Moreover, more and more so-called 'ready-to-use' computer models are being offered and used. We then have to know whether a 'ready-to-use' model is appropriate for our objectives. Therefore, the objective of the course Models for Ecological Systems is: "To provide you with scientifically sound tools which you can use to judge or assess to what extent a model fits your purpose". Judging existing models, rather than developing models from scratch yourself, is the main objective of this course. For this purpose, the following topics are included.
The first topic is related to the content of simulation models (Model Content, MC) for forest and aquatic ecological systems and the associated biological, chemical and physical processes.
The second topic introduces a Good Modelling Practice (GMP) approach, i.e. how to design, build, analyse, and use simulation models to solve certain aspects of problems. Good Modelling Practice facilitates the (re)construction of a model based management study, which allows others to audit and evaluate the overall quality of these studies.
Thirdly, what is taught in MC and GMP will be applied to analyse complex existing simulation models that are used for current research and scenario studies. Students will implement their own (so-called) mini-models that are simplified versions of these complex models.
Finally, the complex models are used during group work to study real-world problems in the domain of Forest and Nature Conservation and Aquatic Ecology, and to learn how to judge such models with the help of the MC and GMP tools.
This course is not suitable for students already familiar with modelling taught in courses like PPS-20306.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- explain the concepts and basics of mathematical simulation models consisting of algebraic and/or differential equations. This includes state variables, rate variables and driving variables, feedback, time coefficient, conceptual model diagram, analysis of units, and numerical integration methods;
- practice mathematical formulations of some elementary (agro)ecological, chemical and physical processes, as part of such models;
- apply modelling according to Good Modelling Practice (GMP). This includes problem analysis, data requirement analysis, conceptual modelling, mathematical modelling, numerical integration, model analysis, model application, interpretation of results and activities to enable re-use of models and model components;
- implement, test and analyse small models (only during practical's and mini-models);
- evaluate models for complex, real world, problem solving in the context of ecological systems according to GMP principles. This includes identifying completeness and adequacy of required input, and checking and interpreting output.


- classroom lectures (25%);
- practical training (30%);
- mini-models (15%);
- group work (30%).
This includes the exam, presentations, a self-assessment, a question hour and 28 hours of scheduled self-study.


- written individual closed book exam with open questions (60%);
- group work: model journal (25%);
- presentations (15%);
To pass each component requires a minimum mark of 5.50).
