Activity b AUDU. Precedes b, c d e End j g h, i k. End End End Estimated Duration (weeks) 11 11 12 10 17 18 15 9 8 9 f h i Part a) Draw the precedence network diagram. Note that you may need to add Start and End nodes when drawing the precedence network diagram, and both of them are assumed to have the estimated duration of zero days. Part b) Find the critical path by identifying all the start-to-end paths and calculating their lengths Part c) Find the slack time of each path and the expected duration of the project Part d Determine the following values for each activity by using PERT CPM solution techniquer the earliest start time, earliest finish time latest finish time, latest start time, and activity slack time. Parte Identify the critical activities and determine the citation of the moject based on PERTICPM solution technique
