We describe a method to simulate the combined physical and dynamical evolution of Jupiter family comets. We integrate all the observed Jupiter family comets and three variant orbits until they leave the family. Regarding the physical modelling, the parameters are the nuclear mass (or radius) and the fraction of the surface area covered by dust mantles formed during previous orbital evolution. This picture is motivated by recent findings concering the coupled orbital and physical evolution of cometary nuclei. I present results concerning the lifetime of comets, both in the active and dormant phase, and snapshot distributions of the number of comets vs perihelion distance.
