Abstract
We have Derringer and Suich’s desirability functions in mind,
especially, the two-sided ones in our analysis throughout this
study. We propose and develop a finite partitioning procedure
of the individual desirability functions over their compact and
connected interval which leads to the definition of generalized desirability functions. We call the negative logarithm of
an individual desirability function having a max-type structure
and including a finite number of nondifferentiable points as
a generalized individual desirability function. By introducing
continuous selection functions into desirability functions and,
especially, employing piecewise max-type functions, it is possible to describe some structural and topological properties of
these generalized functions. Our aim with this generalization is
to show the mechanism that gives rise to a variation and extension in the structure of functions used in classical desirability
approaches.
