This article revisits the standard results of demand theory when the preference relation is a continuous preorder that admits an equicontinuous multi‐utility representation. We study the consumer problem as the constrained maximization of a continuous vector‐valued utility mapping, and show how to rederive those results. In particular, we provide a link between the literature on vector optimization and the analysis of the consumer problem under incomplete preferences.
