SENVAR - A CODE FOR HANDLING CHEMICAL UNCERTAINTIES IN SOLUBILITY CALCULATIONS

Deterministic computer programs are used in many different sciences an d their results are often the base on which decisions are made. In mos t situations the input data to these programs are encumbered with unce rtainties or errors, and therefore the results of the calculations are potentially unreliable. In order to take these factors into account, an uncertainty and sensitivity analysis is often made. This paper pres ents a computer program package where uncertainty and sensitivity anal yses are made on solubility calculations. The input data which are dee med uncertain are stability and solubility constants, pH, pe, and temp erature. The output specifies which of the input data are important, a graph showing the empirical distribution function of the solubility, and some calculated statistics. The approach adopted is simple Monte C arlo sampling of the input data. Copyright (C) 1996 Elsevier Science L td
