      An event that represents the initiation of more than one activity is called the burst event.

    • B. 

      The longest path of a given project gives the maximum duration, while its shortest path indicates the shortest duration.

    • C. 

      The resource allocation programs aim to allocate the given resources in a manner that the project completes in minimum time.

    • D. 

      A non-critical activity may or may not have any free float.

Which of the following statement is correct PERT is deterministic?

Answer» b. PERT is considered as a probabilistic techniques and CPM is considered as a deterministic approach.

Which of the following is characteristic of PERT?

PERT uses event oriented Network. Estimate of time for activities is not so accurate and definite. It is used mostly in research and development projects, particularly projects of nonrepetitive nature. The probabilistic model concept is used.

What is a PERT Mcq?

Programs or Project Management and Review Technique (PERT) is appropriate for those projects where the time required to accomplish different activities are not known. CPM or Critical Path Method is appropriate for the projects that are reappearing (recurring) in nature.

Which of the following is a basic assumption of PERT?

The main PERT assumptions are given along the following lines: The activity durations are independent random variables. The critical paths are independent (i.e. have no activities in common) The normal distribution can be applied (n is sufficiently large) thanks to the central limit theorem.
