In order to obtain the blocking factor BN, we need the mean number of tasks in the join queues. This number can be determined from Eq. (10.165), using Little s theorem:

All Pages: The page header and page footer print on every page. Not with Report Header: Neither the page header nor footer prints on a page with the report header. Not with Report Footer: The page header does not print with the report footer. The report footer prints on a new page. Not with Report Header/Footer: Neither the page header nor the footer prints on a page with the report header or footer.
