Value Function Methods: Indirect And Interactive

  • Valerie Belton
  • Theodor J. Stewart


In the previous chapter, we discussed different methods for assessing value functions expressed in the additive form:
$$V(a) = \sum\limits_{i = 1}^m {{w_i}{\upsilon _i}(a)}$$
on the assumption that the relevant preferential independence axioms hold. For the purposes of this chapter, it will be convenient to reformulate the above into the form:
$$V(a) = \sum\limits_{i = 1}^m {{u_i}(a)}$$
wheretz. u i (a) = w i v i (a). In other words, the partial value functions are now scaled in proportion to their importance weight.
