Figure Ex. 7.1 represents a portion of a precedence diagram. From the data given compute the four float values for Activity E. Solution The float of an activity can be given as F = (TjL - TjE ) - tij The value of float for activity E can be FEC = 25 - 6 - 0 = 19 FEF = 25 - 6 - 8 = 11 FED = 25 - 6 - 4 = 15 FEG = 25 -6 - 10 = 9 If you have any doubts related to the solution please post them in comments..
