Critical path method (CPM) is a step-by-step process by which critical and non-critical tasks are defined so that time-frame problems and process bottlenecks are prevented.
We have the following project. Task times in weeks, as well as predecessors, for each task...

Q5: A construction project consists of activities, immediate predecessors (IPA) and duration in weeks are as shown in the following table. Draw the project network diagram, find the critical path and calculate the corresponding project completion time. Also, find the total float as well as the free float for each activity and the non- critical activities. (10 Marks) ТРА Duration (Weeks) Activity A B نما 4 с 14 D A 10 E F A BD BD с F.H 5 4...
