Abstract

In this paper a two-stage algorithm for finding non- dominated subsets of partially ordered setsis established. A connection is then made with dimension reduction in time-dependentdynamic programming via the notion of a bounding label, a function that boundsthe state-transition cost functions. In this context, the computational burden is partitionedbetween a time-independent dynamic programming step carried out on the bounding label anda direct evaluation carried out on a subset of “real" valued decisions. A computationalapplication to time-dependent fuzzy dynamic programming is presented.
