Comments, with reply, on "Evaluating fault trees (AND and OR gates only) with repeated events" by K.S. Brown

The commenter summarizes his own approach to fault tree analysis (see ibid., vol.R-36, no.2, p.250-54, 1987) and wonders why K.S. Brown (see ibid., vol.39, no.2, p.226-35, 1990), did not compare his own approach with the commenter´s approach. He asks Brown to comment on the latter and raises a number of questions about Brown´s paper. Brown, in reply, points out the limitations of the commenter´s approach and responds to each of the points he raises.<>
