Q1. (10 marks) Construct an activity on arrow network based on the activity descriptions below. Show all your work. Label activities in the network by their activity letters and node numbers. Remove any redundant dependencies and label dummy activities DUMMY1, DUMMY2, etc. • Activities H, R2, T1 start the project. • Activity T2 can start when Activities H, E1 and S are completed. • Activity E1 also depends on Activity R2. • Activity X follows Activity H and precedes Activity...
Consider the following project activities: Calculate the expected time (te) for each activity. Draw an Activity on Node (AON) diagram to reflect the flow of these activities. Calculate the Early Start (ES), Early Finish (EF), Late Start (LS), and Late Finish (LF) for each activity. Calculate the slack for each activity. Identify all activities on the Critical Path. Use the data to calculate the probability the project will finish in 20 weeks (Hint: z-score). Activity A 8 с D E...
