Early Finish Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Early Finish Time = Early Start Time+Safety Stock
EFT = EST+S
This formula uses 3 Variables

Variables Used

Early Finish Time - (Measured in Second) - Early Finish Time is the earliest point in time when the scheduled activity can complete.
Early Start Time - (Measured in Second) - Early Start Time is the earliest point in time when the scheduled activity can begin.
Safety Stock - Safety Stock is the extra stock that is always maintained to mitigate any future risks arising due to stock-outs.

STEP 1: Convert Input(s) to Base Unit

Early Start Time: 19 Day --> 1641600 Second (Check conversion here)
Safety Stock: 2560 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

EFT = EST+S --> 1641600+2560

Evaluating ... ...

EFT = 1644160

STEP 3: Convert Result to Output's Unit

1644160 Second -->19.0296296296296 Day (Check conversion here)

FINAL ANSWER

19.0296296296296 ≈ 19.02963 Day <-- Early Finish Time

(Calculation completed in 00.004 seconds)

Expected Waiting Time for Customers in Queue

Go Expected Waiting Time for Customers in Queue = Mean Arrival Rate/(Mean Service Rate*(Mean Service Rate-Mean Arrival Rate))

Standard Normal Variation

Go Standard Normal Variation = (Normal Variate-Expected Value)/Standard Deviation

PERT Expected Time

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

Time Taken for Manufacturing Model with Shortage

Go Time taken for Manufacturing Model with Shortage = EOQ Manufacturing Model with Shortage/Demand per Year

Independent Float

Go Independent Float = Early Finish Time-Late Start Time-Activity Time

Total Float

Go Total Float = Late Finish Time-(Early Start Time+Activity Time)

Free Float

Go Free Float = Early Finish Time-Early Start Time-Activity Time

Expected Waiting Time for Customers in System

Go Expected Waiting Time for Customers in System = 1/(Mean Service Rate-Mean Arrival Rate)

Time Taken for Purchase Model with No Shortage

Go Time taken for Purchase Model no Shortage = Economic Order Quantity/Demand per Year

Time Taken for Purchase Model with Shortage

Go Time taken for Purchase Model with Shortage = EOQ Purchase Model/Demand per Year

Total Float given Finish Time

Go Total Float given Finish Times = Late Finish Time-Early Finish Time

Standard Deviation given Optimistic and Pessimistic Time

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

Independent Float given Slack

Go Independent Float given Slack = Free Float-Slack of Event

Late Finish Time

Go Late Finish Time = Late Start Time+Duration of Activity

Early Finish Time

Go Early Finish Time = Early Start Time+Safety Stock

Total Float given Start Time

Go Total Float = Late Start Time-Early Start Time

Early Finish Time Formula

Early Finish Time = Early Start Time+Safety Stock
EFT = EST+S

What is Early Finish Time?

Early Finish Time is the earliest point in time when the scheduled activity can complete. For its calculation we use the forward pass; we will start from the beginning and proceed to the end. It is equal to the sum of the early start time and the safety stock.

How to Calculate Early Finish Time?

Early Finish Time calculator uses Early Finish Time = Early Start Time+Safety Stock to calculate the Early Finish Time, Early Finish Time is the earliest point in time when the scheduled activity can complete. We use a forward pass for calculating this. Early Finish Time is denoted by EFT symbol.

How to calculate Early Finish Time using this online calculator? To use this online calculator for Early Finish Time, enter Early Start Time (EST) & Safety Stock (S) and hit the calculate button. Here is how the Early Finish Time calculation can be explained with given input values -> 0.00022 = 1641600+2560.

FAQ

What is Early Finish Time?

Early Finish Time is the earliest point in time when the scheduled activity can complete. We use a forward pass for calculating this and is represented as EFT = EST+S or Early Finish Time = Early Start Time+Safety Stock. Early Start Time is the earliest point in time when the scheduled activity can begin & Safety Stock is the extra stock that is always maintained to mitigate any future risks arising due to stock-outs.

How to calculate Early Finish Time?

Early Finish Time is the earliest point in time when the scheduled activity can complete. We use a forward pass for calculating this is calculated using Early Finish Time = Early Start Time+Safety Stock. To calculate Early Finish Time, you need Early Start Time (EST) & Safety Stock (S). With our tool, you need to enter the respective value for Early Start Time & Safety Stock and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
