Sensitivity analysis of physiochemical interaction model: which pair of parameters is sensitive?

E.N. Ekaka-a, N.M. Nafo, C Isreal-Cookey, E.O. Chukwuocha


The mathematical modelling of physiochemical interactions in the framework of industrial and environmental physics usually relies on an initial value problem which is described by a deterministic system of first order ordinary differential equations. In this paper, we considered a sensitivity analysis of studying the qualitative behaviour of a variation of two model parameters at a time on the solution trajectory of physiochemical interaction over a time interval. Our aim is to use this powerful mathematical technique to select the important pair of parameters of this physical process which is cost-effective.
