B. Resource Loading (33 pts). The network diagram below represents a project plan. a. b. C. Compute the early, late, and slack times. Include your diagram in your paper What is the project duration? What is the critical path -illustrate it on your diagram (such as a dotted line). Ch 8 Assignment Resources: P(ainter); T(rimmer) 0 A START P & T ES ID EF SL Resour LS Dur LF 2 As your text stated, a plan isn't a schedule until resources are assigned. Given that this project has only ONE of each resource (Painter, Trimmer), d. Using any approach you wish (e.g. trial and error), develop a Resource Loading schedule for the Painter (P) and Trimmer (T). Hint: This involves placing the appropriate task ID in the daily cells in the Loading Schedule (see below). This example says that the Painter will do task A from days 1-3. Complete this Schedule, keeping in mind task predecessors, task duration, and the fact that there is only one painter and one trimmer Resource Loading Schedule for Tasks A-G Painter A AIA Trimmer Day 01 2 3 45 6 7 8 9 10 11 12 13 14 15 16 e. Has the project duration changed when you loaded the resources? Explain. f. Have the critical tasks changed after creating the loading schedule? If so, what is the new critical path?

Answer #1

Network Diagram - Critical Path Method: in Hand written Format

A İEF FPF LSB LF Es Ealis 033 325 Finis么 LF- Late Rnish 12 A- Activitu 1D Fa Total Foal 2 A PA 63S 6 F- LF- CS Scanned with C

From the Network Diagram, It is clear that Critical Path is ADEH, as activities on that critical path have zero float, Further, Project needs at least 11 days time to finish as Critical path duration is 11 Days, which is here Maximum time, the critical Path is shown with Bold Arrow

Activity Duration Early Start Late Start Early Finish Late Finish Slack or Float Time = Late start - Early Start = Late Finish - Early Finish Critical path activities Yes or No
A 3 0 0 3 3 0 Yes
B 2 0 1 2 3 1 No
C 2 0 4 2 6 4 No
D 2 3 3 5 5 0 Yes
E 4 5 5 9 9 0 Yes
F 6 2 3 8 9 1 No
G 3 2 6 5 9 4 No
H 2 9 9 11 11 0 Yes
Resource Loading
Activity Duration Resource 1 2 3 4 5 6 7 8 9 10 11
A 3 Painter 1 1 1
B 2 Painter 1 1
C 2 Trimmer 1 1
D 2 Painter 1 1
E 4 Trimmer 1 1 1 1
F 6 Trimmer 1 1 1 1 1 1
G 3 Painter 1 1 1
H 2 Painter plus Trimmer 2 2
Total 3 3 3 3 3 2 2 2 1 2 2
Resource Leveling
Activity Duration Resource 1 2 3 4 5 6 7 8 9 10 11 12 13 14
A 3 Painter 1 1 1
B 2 Painter 1 1
C 2 Trimmer 1 1
D 2 Painter 1 1
E 4 Trimmer 1 1 1 1
F 6 Trimmer 1 1 1 1 1 1
G 3 Painter 1 1 1
H 2 Painter plus Trimmer 2 2
Total 2 2 2 2 2 2 2 2 2 2 1 1 2 2

After Resource loading and Leveling Project Duration has changed,

The new Project duration = 14 Days, or project needs at least 14 Days time to complete,

there will be new critical path as We have done Resource leveling and considering, there is only one Painter and One Trimmer, The New critical path would be ABGEH
