cost is related to the response time required to generate information and
communicate it. For systems with low response time, cost is high.
Value of information
Before
a particular piece of information is acquired, decision-makers must know its
value. In decision theory, the value of information is the value of the change
in decision behavior because of the information. The change in the behavior due
to new information is measured to determine the benefits from its use. To
arrive at the value of new information, the cost incurred to get this
information is deducted from the benefits.
