A SYSTEM FOR THE AUTOMATION OF ONE-AT-A-TIME SENSITIVITY ANALYSIS IN ODE SYSTEMS

Matheus Fajardo Galvão, Marcelo Lobosco

Resumo


Sensitivity analysis is a widely used tool in computing modeling, being used fordistinct purposes, such as a better understanding of the relationship between parameter values in amathematical model and its results, and the identification of parameters whose change in their valuesimplies in a larger variation in the results of a model, among others purposes. Several approachescan be used to perform sensitivity analysis. One of the simplest is one-at-a-time, which analyzes theimpact of changing a single parameter on a model while keeping the others one fixed. Depending onthe number of parameters and the variations adopted, the sensitivity analysis of a large model maygenerate a large volume amount of results and it can be hard to identify the most sensitive parametersof the model. This paper presents a tool that automates the identification of these parameters.
