On product-form approximations of cooperating stochastic models

The main focus of this paper is to enlarge the applicability of product-form solutions by regarding models that yield this property as approximations of models that do not. To achieve this, we make use of Reversed Compound Agent Theorem (RCAT)[2, 3] and devise a useful and practical method to modify non-product form models into productform ones. Our technique provides meaningful approximations of the original models.
