A T= 4 T= 3 F T= 3 T= 3 D E G T= 1 T= 2 T= 2 The network diagram of a project along with the activity durations (T) is given in the figure. Which activities form one of the critical paths? @orsdemir. Copyrighted Content. Cannot be posted. CDEG O ABF О СВF O CF O None of these
This was a three part question. Bartelby helped me get A and B. The picture for Part A is the network diagram and Part B's answer is below for the critical path. My question I need to answer is Part C which is in the second picture. Part B There are the following paths in the project network. A –> B –> D –> G –> J = 2 + 4 + 2 + 3 + 7 = 18 A –> B –> E –> G – >J = 2 + 4 + 1 + 3 + 7 = 17 A –> B –> F –> H –> J = 2 + 4 + 8 + 5 + 7 = 25 A –> C –> F –> H –> J = 2 + 5 + 8 + 5 + 7 = 27 A –> C –> F –> I –> J = 2 + 5 + 8 + 4 + 7 = 26 The longest path in all the possible paths of the project network is A –> C –> F –> H –> J with the longest time. Therefore, the project duration is 27 days.
Three activities are candidates for crashing on a project network for a large computer installation (all are, of course, critical). Activity details are in the following table: Activity A B C Normal Time Crash Time Normal (days) (days) Cost 7 6 4 11 2 9 $5,000 $1,400 $4,000 Total Cost with Immediate Crashing Predecessor(s) $5,600 $3,300 $6,400 a) Activity that should be crashed first to reduce the project duration by 1 day is A b) Activity that should be crashed next to reduce the project duration by one additional day is A B A B C ect: 0
The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table. Draw the project network, and compute the expected time and variance for each activity. Develop an activity schedule for this project, compute activity slack time and identify critical path.

Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Dave's earliest start (ES) and earliest finish (EF) are: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A B C D 7 6 3 2 A A Activity A ES EFGH EF 7 3 6 11 6 B B C, E D, F
