FAQs on Handwritten Notes: PERT and CPM - Industrial Engineering - Mechanical Engineering

1. What is PERT and CPM in Mechanical Engineering?
Ans. PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are project management tools used to schedule, organize, and coordinate tasks within a project in mechanical engineering. PERT focuses on time management, while CPM emphasizes cost efficiency.
2. How are PERT and CPM different from each other?
Ans. PERT is a probabilistic model that allows for uncertainty in task times, while CPM assumes a deterministic model with fixed task durations. PERT also incorporates three time estimates for each task (optimistic, pessimistic, and most likely), while CPM uses a single duration estimate.
3. What are the key benefits of using PERT and CPM in mechanical engineering projects?
Ans. PERT and CPM help identify the critical path of a project, determine project completion time, allocate resources efficiently, and minimize project delays. They also facilitate effective communication among project team members and stakeholders.
4. How can PERT and CPM be applied in real-world mechanical engineering projects?
Ans. In real-world projects, PERT and CPM can be used to plan and schedule tasks such as designing, manufacturing, testing, and installation. By identifying critical activities and dependencies, project managers can optimize project timelines and resource allocation.
5. Are there any limitations to using PERT and CPM in mechanical engineering projects?
Ans. Some limitations of PERT and CPM include the assumption of independent tasks, the need for accurate task duration estimates, and the lack of flexibility in handling unexpected changes or disruptions in the project schedule. Additionally, these methods may not account for resource constraints or external factors impacting project delivery.
