  Interacting particle systems are continuous time Markov processes which are
used to construct models in many disciplines. Monotonicity is a property that
some interacting particle systems possess. A monotone interacting particle
system is called attractive. A benefit of attractiveness is that it simplifies
certain calculations, one of which is the ability to use some computational
algorithms to sample exactly from the stationary distribution of an ergodic
process. Monotonicity is well understood for spin systems such as the contact
process. Spin systems only include two particle types however, while in many
applied models, it is desirable to include more species of particles. In this
paper a general framework of monotonicity will be outlined for a certain class
of multitype contact processes.
