To evaluate the performance of hybrid vehicular network framework, a unified vehicular network utility function
[OMEGA] is defined as
The utility function
of an individual under coercion from the full social income maximizes when the rate of technical substitution in consumption (the slope of the curve of indifference of the maximizer individual, denoted Ui) is equal to the technical rate of substitution in production (slope of the curve of production possibilities, denoted CPP, of the maximizer individual), i.e.
(3) However, this result applies only to the singular class of cubic utility functions
, for which changes in risk at orders above the third are irrelevant.
By this definition, visual satisfaction level could be modeled as a utility function
of variables describing the physical conditions, and preference is a comparative result of comparing the utility values corresponding to two (or more) conditions.
The Agent's utility function
. To obtain the solution of optimal contract, according to our assumption in Section 2.1, the agent is risk-neutral and the utility functions
of the agent are linear, i.e.,
I have observed in a variety of universities, especially in the United States, that professors and supervisors encourage their students to play around with the models, to try to make them more realistic, to infuse a degree of humanity in the utility functions
and the assumptions.
If the utility functions
are interdependent, the endogenous variable for price and quantity in each equation should be significant.
Figure 1 compares two exponential utility functions
for varying levels of risk tolerance - risk averse vs.
Some of them are chosen from the previous works and some factors are newly defined in the proposed utility function
. In this paper, the utility function
is also adopted as a decision-making criterion in the assessment and selection of parking.
where the utility functions
[U.sub.1](x) and [U.sub.2](x) are risk aversion functions.
