Determination of optimal pipe diameters for radial fixed-track district heating networks

Abstract

This paper presents the basics of Bellmann’s dynamic programming, to be applied for radial fixed-track district heating networks. A decision-making model thereof is produced, and Garbai’s scaling method [1] is applied in a new, narrower interval by using a tagging method well-known from computer science. Thereby the result yielded coincides with that of the previous method, but the number of calculations to be performed is reduced considerably.
