The Modified Levermore-Pomraning (MLP) equations have been recently proposed by Akcasu as a treatment of transport in stochastic media with scattering. Using the bimaterial Markovian density statistics originally introduced by Pomraning, a new derivation of the MLP equations is presented for the continuous transport equation with energy dependence and 'density' sources. A heuristic MLP model is also introduced for calculations in finite slabs and is compared to the Levermore-Pomraning model using theoretical considerations. Numerical comparisons of the MLP and LP models are presented for a set of standard tests as well as related problems for which we give reference results.
