Concept explainers
A.
Interpretation: Thepredecessors of every activity in the project are to be determined.
Concept Introduction: Network diagram is a graphical representation of tasks and events happening in a project. It depicts the workflow and is used to compute the total duration of the project.
B.
Interpretation: The critical path is to be identified by enumerating all the paths from node 1 to node 10 and computing the duration.
Concept Introduction: Network diagram is a graphical representation of tasks and events happening in a project. It depicts the workflow and is used to compute the total duration of the project.
C.
Interpretation: The critical path is to be identified by computing the earliest and the latest start and finish times.

EBK PRODUCTION AND OPERATIONS ANALYSIS
- the manpower requirement for each activity in a construction project is given in the attached table. All activities are scheduled to start at it's earliest Start times (1) draw the project network and determine the critical path and durationarrow_forwardA group of developers is building a new shopping center. A consultant for the developers has constructed the following project network and assigned activity times, in weeks. Determine the earliest and latest activity times, activity slack, critical path, and duration for the project.arrow_forwardDave 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.
