[#126] ____________ models assumes that the values of the variables do not change with time during a particular period.
Correct Answer

(A) Static Models

Explanation

Solution: Static Models assumes that the values of the variables do not change with time during a particular period. The static model describes the structure of a distributed parameter system, i.e. its state at a specific time instant. The intersection models relate the parameters that are to be combined in a composite field by means of their distribution models.

[#127] A _____________ models considers time as one of the important variable.
Correct Answer

(B) Dynamic Models

Explanation

Solution: A Dynamic Models considers time as one of the important variable. Dynamic models are generally models that contain or depend upon an element of time, especially allowing for interactions between variables over time. A separate idea with the same name is models that are updated over time with new data. In the case of Systems Dynamics, we often have variables that are looped.
