Which activities have zero slack?
Activities with zero slack cannot be delayed without affecting the entire project duration and are called critical activities.
When activity times are uncertain an activity’s most likely time is the same as its expected time select one True False?
Terms in this set (25) Critical activities are those that can be delayed without delaying the entire project. A critical activity can be part of a noncritical path. When activity times are uncertain, an activity’s most likely time is the same as its expected time.
Which path is the critical path?
The critical path (or paths) is the longest path (in time) from Start to Finish; it indicates the minimum time necessary to complete the entire project.
Which activities can be delayed without delaying the entire project?
Slack is the amount of time an activity can be delayed without delaying the entire project.
Can activity d be delayed without delaying the entire project?
ii) Activity D cannot be delayed without delaying the entire project, since it is an activity in the critical path A-D-F-H.
Can activity C be delayed without delaying the entire project if so by how many weeks?
Can activity C be delayed without delaying the entire project? If so, by how many weeks? Yes, C can be delayed by 2 weeks.
What is CPM and PERT technique?
1. PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.
What are the major differences between PERT and CPM?
PERT vs CPM
| Abbreviation | |
|---|---|
| PERT – Project Evaluation and Review Technique | CPM – Critical Path Method |
| Focus | |
| PERT – The main focus of PERT is to minimise the time required for completion of the project | CPM – The main focus of CPM is on a trade-off between cost and time, with a major emphasis on cost-cutting. |
| Orientation type | |
What is the basic difference between PERT and CPM?
PERT deals with unpredictable activities, but CPM deals with predictable activities. PERT is used where the nature of the job is non-repetitive. In contrast to, CPM involves the job of repetitive nature. There is a demarcation between critical and non-critical activities in CPM, which is not in the case of PERT.
What is PERT CPM example?
In PERT, time is not related to cost. In CPM, the objective is developing an optimum time-cost relationship. PERT is suitable in defense projects and R&D where activity time cannot be reliably predicted. CPM is suitable for problems in industrial setting, plant maintenance, civil construction projects etc.
What is CPM example?
For example, in the diagram below, activities E, F, G, H, and I make up the critical path. Their total duration is 100 hours. Activities B, C, D and E make up the second longest sequence with a total duration of 90 hours. The difference between their total duration is 10 hours.
What is activity in PERT CPM?
Each activity (or sub-project) in a PERT/CPM Network is represented by an arrow symbol. Each activity is preceded and succeeded by an event, represented as a circle and numbered. At Event 3, we have to evaluate two predecessor activities – Activity 1-3 and Activity 2-3, both of which are predecessor activities.
What is the use of PERT and CPM?
PERT (Program Evaluation and Review Technique) was first used in the development of submarines capable of firing Polaris missiles. CPM (the Critical Path Method) was used to manage the annual maintenance work in an oil and chemical refinery.
Why do we use CPM?
Critical path method (CPM) is a resource-utilization algorithm for scheduling a set of project activities. The essential technique for using CPM is to construct a model of the project that includes the following: A list of all tasks required to complete the project. The dependencies between the tasks.
What is the full form of CPM?
Cost per mille, the advertising cost per thousand views. Cost per thousand impressions, the online advertising equivalent.
