(a) Continuous modelling cannot be performed using computer-based modelling and simulation techniques,
1-True
2-False
(b) A network diagram is typically an example of:
1. A physical model.
2. An abstract model.
(c) A "white box" system is one in which the internal elements and associated couplings within the system boundary are not observable.
1-True
2-False
(d) Scenario development, analysis, and planning has superseded General Systems Theory in the 21st century and many industries and organisations are increasingly adopting it instead.
1-True
2-False
(e) Synthesis for a system can be performed using simulation models and methods.
1-True
2-False
(f) Cybernetics is closely associated with General Systems Theory.
1-True
2-False
(g) There are only three possible stable states in which a dynamic system can exist, namely static, transitory, and equilibrium.
1-True
2-False
(h)When defining a system model it is optional as to whether we define a system boundary, or boundaries for our model.
1-True
2-False
(i)Open loop systems generally have fewer inputs (taken from their environment) than closed loop systems.
1-True
2-False
(i) Which of the following is an example of a nonlinear dynamical system? (Choose the best correct option as your answer if you consider more than one option is correct.)
1. The supply chain of a brewery.
2. The global climate.
3. The human body.
4. The stock price of Enron Corporation until about mid-2001.
5. All of the examples listed here.
(j) If any element, subsystem, or coupling within a dynamic system fails then the dynamic system will irreversibly transition to a stable static state.
1-True
2-False
(k) We cannot model a particular system using both discrete and continuous model types since we can only use one or the other but not both.
1-True
2-False
(l) If we can develop a system model that enables us to simulate future possible scenarios ( behaviours, actions, interactions, and states) then we may attempt to change the characteristics of the system, change the interactions between the system and its environment, and/or change relevant factors or constraints within the system's environment in order to seek an actual future outcome we find to be more desirable.
1-True
2-False
(m)General Systems Theory encourages us to use a holistic approach to systems-based analysis and synthesis.
1-True
2-False
(n) Although the Principle of Superposition does not apply for nonlinear systems and corresponding system models (that also model as nonlinear) we can overcome this by ignoring any feedback stages of the system in our modelling and assuming the system is linear.
1-True
2-False
(o) Organisational Charts are an example of an abstract model of a system.
1-True
2-False
(p)The evaluation of various possible scenarios (either future or past) using simulation models can be tremendously valuable as a tool used in strategic plan development.
1-True
