Scheduled Time given Probability Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Scheduled Time = (Standard Deviation*Probability Factor)+Mean Time
T_s = (σ*Z)+t_e
This formula uses 4 Variables

Variables Used

Scheduled Time - (Measured in Day) - Scheduled Time is the time which is made as per the experience and practice by the creator of the project.
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.
Probability Factor - The probability Factor is a term used to find the probability of a project getting completed in the expected time.
Mean Time - (Measured in Day) - Mean Time, also called expected time is the time needed to complete an activity.

STEP 1: Convert Input(s) to Base Unit

Standard Deviation: 1.33 --> No Conversion Required
Probability Factor: 2.03 --> No Conversion Required
Mean Time: 4 Day --> 4 Day No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_s = (σ*Z)+t_e --> (1.33*2.03)+4

Evaluating ... ...

T_s = 6.6999

STEP 3: Convert Result to Output's Unit

578871.36 Second -->6.6999 Day (Check conversion here)

FINAL ANSWER

6.6999 Day <-- Scheduled Time

(Calculation completed in 00.004 seconds)

Optimistic Time given Expected Time

Go Optimistic Time = (6*Mean Time)-(4*Most Likely Time)-Pessimistic Time

Mean or Expected Time

Go Mean Time = (Optimistic Time+(4*Most Likely Time)+Pessimistic Time)/6

Most Likely Time given Expected Time

Go Most Likely Time = (6*Mean Time-Optimistic Time-Pessimistic Time)/4

Standard Deviation given Probability Factor

Go Standard Deviation = (Scheduled Time-Mean Time)/Probability Factor

Scheduled Time given Probability Factor

Go Scheduled Time = (Standard Deviation*Probability Factor)+Mean Time

Expected Time given Probability Factor

Go Mean Time = Scheduled Time-(Standard Deviation*Probability Factor)

Probability Factor

Go Probability Factor = (Scheduled Time-Mean Time)/Standard Deviation

Pessimistic Time given Expected Time

Go Pessimistic Time = 6*Mean Time-Optimistic Time-4*Most Likely Time

Earliest Expected Occurrence Time of Event j

Go Earliest Occurrence Time of j = Earliest Occurrence Time of i+Duration of i-j

Earliest Expected Occurrence Time of Event i

Go Earliest Occurrence Time of i = Earliest Occurrence Time of j-Duration of i-j

Expected Time of Activity i-j

Go Duration of i-j = Earliest Occurrence Time of j-Earliest Occurrence Time of i

Slack of Event i or j

Go Slack of an Event = LOT of Event j-Earliest Occurrence Time of j

Optimistic Time given Standard Deviation

Go Optimistic Time = -(6*Standard Deviation-Pessimistic Time)

Standard Deviation of Activity

Go Standard Deviation = (Pessimistic Time-Optimistic Time)/6

Pessimistic Time given Standard Deviation

Go Pessimistic Time = 6*Standard Deviation+Optimistic Time

Least Allowable Occurrence Time of Event i

Go LOT of Event i = LOT of Event j-Duration of i-j

Least Allowable Occurrence Time of Event j

Go LOT of Event j = LOT of Event i+Duration of i-j

Scheduled Time given Probability Factor Formula

Scheduled Time = (Standard Deviation*Probability Factor)+Mean Time
T_s = (σ*Z)+t_e

What is Probability of Occurrence of an Event?

The probability of a project to complete at expected time is 50% and this probability increases or decreases according to the increase or decrease on scheduled time. Since the probability distribution of the entire project is in normal distribution, the probability can be determined using probability factor. If the factor is 0, probability of completing project at expected time is 50%

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.2
