  Lattice investment projects support process model with corruption is
formulated and analyzed. The model is based on the Ising lattice model of
ferromagnetic but takes deal with the social phenomenon. Set of corruption
agents is considered. It is supposed that agents are placed in sites of the
lattice. Agents take decision about participation in corruption activity at
discrete moments of time. The decision may lead to profit or to loss. It
depends on prehistory of the system. Profit and its dynamics are defined by
stochastic Markov process. Stochastic nature of the process models influence of
external and individual factors on agents profits. The model is formulated
algorithmically and is studied by means of computer simulation. Numerical
results are given which demonstrate different asymptotic state of a corruption
network for various conditions of simulation.
