Abstract :
In this paper a methodology to the analysis of bifurcations of variable structure systems is proposed. This methodology, based on the use of symbolic computation packages, is derived from the conditions of the existence of variable structure bifurcations of planar systems, allowing a multi-parametric analysis, without intensive numeric computations. The proposal is applied to a predator-prey model with human intervention
