The paper examines the computational efficiency of three methods of evaluating multiple diffraction integrals commonly encountered in electromagnetic problems. The solution based on the repeated integrals of the error function originally derived by Vogler is elegant, relatively easy to program, computationally inefficient, but accurate. For practical applications, the computational technique used must be amenable to rapid evaluation and yield an acceptable degree of accuracy. Following the analysis of Saunders and Bonar for propagation over multiple knife-edge models of building rows of irregular height and spacing, the Monte-Carlo integration technique .is extended to consider three-dimensional knife-edge and plateau diffraction.
