Most Likely Time given Expected Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Most Likely Time = (6*Mean Time-Optimistic Time-Pessimistic Time)/4
t_m = (6*t_e-t₀-t_p)/4
This formula uses 4 Variables

Variables Used

Most Likely Time - (Measured in Day) - Most Likely Time is the normal time activity would take.
Mean Time - (Measured in Day) - Mean Time, also called expected time is the time needed to complete an activity.
Optimistic Time - (Measured in Day) - Optimistic Time is the shortest possible time to complete the activity if all goes well.
Pessimistic Time - (Measured in Day) - A Pessimistic Time is the longest time that an activity could take if everything is wrong.

STEP 1: Convert Input(s) to Base Unit

Mean Time: 4 Day --> 4 Day No Conversion Required
Optimistic Time: 2 Day --> 2 Day No Conversion Required
Pessimistic Time: 10 Day --> 10 Day No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_m = (6*t_e-t₀-t_p)/4 --> (6*4-2-10)/4

Evaluating ... ...

t_m = 3

STEP 3: Convert Result to Output's Unit

259200 Second -->3 Day (Check conversion here)

FINAL ANSWER

3 Day <-- Most Likely Time

(Calculation completed in 00.004 seconds)

What is PERT ?

Program Evaluation and Review Technique (PERT) is a method used to examine the tasks that are in a schedule and determine a variation of the Critical Path Method (CPM). It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project. It estimates the shortest possible time each activity will take, the most likely length of time, and the longest time that might be taken if the activity takes longer than expected.

What is Central Limit Theorem and Critical Path?

Central Limit Theorem: The theorem states that a project consists of a large number of activities, where each activity has its own mean time (te), standard deviation (σ), variance (σ2) and also its own ß-distribution curve.
Critical Path: The time-wise longest path is the critical path. In this path, any type of delay, in any event, will cause a delay in the project. These are shown by double lines or dark lines in a network.
