The application of interval mathematics to utility economic analysis
John N. S. Matthews, Robert Broadwater, L.L. Long · IEEE Transactions on Power Systems · 1990
A review is presented of the basic concepts of revenue requirement theory and the varying forms of revenue requirement analysis. The discussion is followed by a brief overview of interval mathematics and its algebraic structure. An example problem using break-even analysis both in traditional single-value form and in interval form, is presented.>
