The Sherry Solera: An Application of Partial Difference Equations

Resumo

The sherry solera is a sequential batch-mixing process designed to produce sherry with uniform quality from year to year. The startup of solera is modeled by linear partial difference equations that are solved by four different theoretical methods. Three apparently, but not actually, different solutions are found. The aim of this paper is to illustrate the use of these methods in solving linear partial difference equations.
