Question

Please use the information below to draw and solve the network on a piece of paper by: • Complete the forward and backward pass • Identify the critical path Fill in the requested information (Example: ESA - Early Start of Activity A; LFA - Late Finish of Activity A, etc) Duration 3 Predecessor Relationship N 2 - Activity Activity ID Contract sign A Survey Target market C Data collection Presentation Analyze results Demographics G Closing H FS Lag 3 N - 2 E,F,G Late Finish (0.5 marks each) Fill in the data in the table below with the network times: Activity ID Early Start Early Finish Late Start Activity A Activity B Activity C Activity D Activity E Activity F Activity G Activity H (2 marks) State the Total Float for activity ID-E: (2 marks) State the Critical Path for this network (example: ABCD)?

Answer 1

Construct the network diagram by the following way. Forward and backward pass. A EF ES A EF - LSDLF DLF LSD LF LSDLF Where, ES is the Early Start EF is the Early Finish A is the Activity LS is the Late Start

LF is the Late Finish D is the Duration S is the Slack AB 1 Activity ID Early Start Early Finish Late Start Late Finish 2 Activity A 0 3 Activity B 4 Activity C 5 Activity D 6 Activity E 7 Activity F 8 Activity G 6 9 Activity H 15 Uw The total float of the activity ID: E is 8 Hence, the critical path for this network is ACDFH.
