# Vensim online course – advanced version

This course is intended for users that are new to Vensim. Only basic computer skills are needed. No statistical or specific mathematical education is required.

This course allows the student to acquire, in a time-efficient and uncomplicated manner, knowledge in the formation and construction of dynamic models using Vensim. The course will guide students through the construction of realistic hypotheses and elaborate behavior models as well as inclusion of external data.

At the end of the course, the student will be able to:

• Describe the components of a complex system.
• Diagnose the natural evolution of the system under analysis.
• Create a model of the system and present it using the simulation software.
• Carry out simulations and experiment with the model.

The documentation for the course will be provided in electronic format. Vensim PLE Plus is used during the basic course. The instructor is available to the student for any help during their studies, the support forum is also available for search and help.

Progress is continuously monitored through the completion of the different exercises and study cases.
