Test: CPM & PERT Level - 2 - Mechanical Engineering MCQ

If the earliest starting time for an activity is 10 weeks, the latest finish time is 30 weeks and the duration time of the activity is 11 weeks, then the total float is equal to

The earliest occurrence time for event '1' is 8 weeks and the latest occurrence time for event' 1' is 26 weeks. The earliest occurrence time for event '2' is 32 weeks and the latest occurrence time for event '2' is 37 weeks.

If the activity time is 11 weeks, then the total float will be

Consider an activity having a duration time of T_ij. E is the earliest occurrence time and L the latest occurrence time (see figure given).

Consider the following statements in this regard:

1. Total float = L_j − E_i − T_ij

2. Free float = E_j − E_i − T_ij

3. Slack of the tail event = L_j − E_i

Of these statements

In a small engineering project, for an activity, the optimistic time is 2 minutes, the most likely time is 5 minutes and the pessimistic time is 8 minutes. What is the expected time of the activity?

Consider the following project network

The number of merge events are

For the network shown in the given figure, the expected completion time of the project is

The total float associated with the activity shown below is

Consider the network. Activity times are given in number of days. The earliest expected occurrence time (TE) for event 50 is

The variance (V1) for critical path a → b = 4 time units, b → c = 16 time units, c → d = 4 time units, d → e = 1 time unit. The standard deviation ‘d’ of the critical path a → e is

Consider an activity ‘A’ which is having the following values:

N_C = Rs 100

N_T = 3 days

C_C = Rs 150

C_T = 2 days

Find the cost of crashing activity A’ by single day

A project consist of following activities

Minimum time required to complete the project in (days) is __________

For the given project, to draw a network diagram how many dummy activities are required?

In the network shown below. The critical path is along

Consider the network shown in figure. The three time estimates for activities are given along the arrows. Then the standard deviation of the project is

Consider the following project find the critical path duration.

The expected project completion time is found to be 34 days. The standard deviation of the critical path is 5 days. Find the probability of completing the project in 39 days.

For the project network shown below calculate latest finish time of node 4.
