WebSep 28, 2024 · A uniformity index is proposed to address this limitation. While the definition of the index is simple, the maximization of it is expected to lead to network designs with an increasingly uniform flow, at each node, in which the burden of carrying inflows (or outflows) at each node is shared evenly among all input (or output) pipes.
