Resilience is the ability of a system to overcome difficulties. Resilience develops within the system's organization and dynamics. The better the internal structure and the interrelations of a system are known, the better the degree of resilience of the system can be determined. This is illustrated by a simple predator-prey model.
An important fact in the concept of resilience is that it is not related to a one-time event. A specific type of difficult event that occurs repeatedly has to be overcome. The predator-prey model illustrates this point in a way that is easy to understand because of its simple structure. The limits of resilience are also demonstrated.
The quiz consists of 17 web pages that are interlinked. Various disruption scenarios are considered and the resulting dynamics are discussed in the quiz. The users have to answer a set of yes-no questions referring to the future development of the system. The quiz can be taken online or downloaded.
Two possible applications are recommended:
- The students take the quiz individually. No previous knowledge on resilience is required as the term is defined properly in the quiz. At the end, further contexts where the term is applied are described and a warning of oversimplification is delivered.
- A lecturer presents the quiz in a course. Each question is first discussed with the students and the answers are then considered.
For those interested in the mathematical background of the quiz, the equations used in the model are described on the last page.
