  In this paper we study the volatility and its probability distribution
function for the cumulative production based on the experience curve
hypothesis. This work presents a generalization of the study of volatility in
[1], which addressed the effects of normally distributed noise in the
production process. Due to its wide applicability in industrial and
technological activities we present here the mathematical foundation for an
arbitrary distribution function of the process, which we expect will pave the
future research on production and market strategy.
