Hybrid dynamics of multi-species resource exploitation

Abstract In this paper, we analyze a bio-economic model of exploitation renewable commercial resources. To take into account the typically continuous-time modeling biological species and, instead, specialized harvesting activities, which by its nature cannot change continuously, resulting dynamic system is hybrid type, i.e. continuous for variables and discrete economic ones. Through discretization variables, problem then reformulated means three-dimensional map. Of map, study properties to understand how parameters influence long-run availability
