Q1 & 3

Problem 1 The following table gives expected times and variances for a probabilistic duration type of project (we are not given and we don't need the optimistic, most likely, and pessimistic time estimates). Expected Activity Variance Time 0.44 4 B 3 0.69 C 7 2.25 D 11 2.25 E 4 0.11 F 9 1.36 G 6 0.44 H 6 0.69 1 7 1.36 J 13 1.00 K 3 0.44 Given the project network below, find the early start (ES), Early Finish (EF), Late Start (LS) and Late Finish (LF) time indices, for the network show below. Use the "expected time" for the critical path method. D START c You should only have numbers in the following table. If you need to write some notes for me, please write it in the question/space that follows next. Activity ES EF LS LF A B D E F G H K If you need to write any notes for me for the above numbers, please use the next question/space to do so Which is the critical path? O AD-K O A-E-I-K O A-F-I-K OB-F1-K O C-G-I-K O C.H.J.K What is the expected time and variance for completing this critical path? Expected time? Variance
