The OMNIUM technique, presented here, takes the transitory course of t
he waste heat supply and heat demand into account and was concertedly
developed for the use in the sectors small and medium-scale industry,
trade and consumption on a small scale and was translated into a softw
are programme. In the paper, the diagram of an industrial plant and th
