Chapter 13, Problem 3P
A construction project has the following network and activity times:
- a. Make a forward pass and a backward pass on the activity times.
- b. Find the slack for each activity.
- c. Prepare a Gantt chart for this project.

PERT could be used to answer which of the following managementquestions?
A. Can we delay a particular activity and still finish the project on time?B. When are we scheduled to start a particular activity?C. Which activities should be finished on time?D. All of the above.
What is the optimal plan for expediting some activities so as to minimize the total cost of performing the project within the deadline?
The activities related to a project with their immediate predecessors have been provided in the table. You are required to perform a critical path analysis by computing the slack time.

- The following statement about a noncritical activity is FALSE: A. Delaying it beyond its slack will cause the delay of the whole project.B. It can be delayed.C. Both A and B.D. Neither A nor B.arrow_forward27. Consider a project with six activities: G, B, C, D, E, and F. Assume G and F can be started as soon as the project is kicked off. B can start as soon as G is completed, C can start as soon as both G and F are completed. D will start as soon as both B and C are completed. E will start as soon as D finishes. Which of the following choices is the correct collection of immediate precedence relationships in the project network? G--> B, F--> C, B --> D, C--> E, D--> E, F--> D G--> B, G--> C, B --> D, C--> D, D--> E, F--> C G--> B, G--> C, B --> D, C--> D, D--> E, D--> F None of choices G--> B, F--> C, B --> D, C--> D, D--> E, F--> D G--> B, G--> C, B --> D, C--> D, D--> E, D--> Farrow_forwardINSTRUCTIONS: Draw the AON network for Exercise 14 (pg ASSIGNMENT 200 & 201). Complete the forward and backward passes, calculate total slack for each activity, identify the critical path, identify the total project length (or how long it will take to complete the project) based on days, calculate free slack for appropriate activities, and create the Gantt chart. When creating the Gantt chart, you must include slack into the schedule.arrow_forward

(b) Identify the critical path, and show your working.arrow_forwardTo help with preparations, a couple has devised a project network to describe the activities that must be completed by their wedding date. A project network with 10 activities and 13 directed arcs is shown. Activity Start is connected to activity A and to activity B. Activity A is connected to activity C and to activity D. Activity B is connected to activity E. Activity C is connected to activity H. Activity D is connected to activity F and to activity G. Activity E is connected to activity F and to activity G. Activity F is connected to activity H. Activity G is connected to activity Finish. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities.

- Explain how project scheduling software may help. Please explain my question.arrow_forwardThe following is NOT one of the advantages of CPM and PERT:a) Straightforward concept and not mathematically complex.b) Graphical networks help highlight relationships among project activities.c) Critical path & slack time analyses pinpoint activities that need tobe closely watched.d) Project documentation and graphs point out who is responsible for variousactivities.e) Precedence relationships must be specified and networked together.f) Applicable to a wide variety of projects.arrow_forward. True/False Statements (Tick the correct option) Selection of the critical path in network activity diagram for any project, is always focused onresult of the minimum time duration of the critical activities [ True / False ] Suppose, we have total 03 activities in the project “X”; namely L, M and N respectively. An activity “M” is the immediate successor of the activity “L”, while the activity “M” is the immediate predecessor for the activity “N”. According to this scenario, an activity “M” will be the last activity of the project “X” in the network activity diagram [True / False ] The dummy activity consumes both time and resources [True / False ] Towards the optimal solution through stepping stone method, when degeneracy problem is occurred, the next step is to focus on searching lowest value on the independent position in a non-allocated cells [True / False ] Hungarian algorithm, first convert any given assignment matrix into row reduction matrix [True / Falsearrow_forward
