Every fifty thousand miles an aircraft undergoes a complete inspection that involves 10 different diagnostic checks. Three of the checks require 4 hours each to complete, three more require 7 hours each to complete, and four of the checks require 15 hours each to complete. Moreover, none of the 15-hour checks can be started until all the 4-hour checks have been completed. Draw a project digraph for this scheduling problem.
