Late Finish Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Late Finish Time = Late Start Time+Duration of Activity
LFT = LST+dur
This formula uses 3 Variables

Variables Used

Late Finish Time - (Measured in Second) - Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint.
Late Start Time - (Measured in Second) - Late Start Time is the latest point in time when the scheduled activity can begin so as not to delay the project completion date or any constraint.
Duration of Activity - (Measured in Second) - Duration of activity is the total number of work periods required to accomplish the work of the activity.

STEP 1: Convert Input(s) to Base Unit

Late Start Time: 23 Day --> 1987200 Second (Check conversion here)
Duration of Activity: 21 Day --> 1814400 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

LFT = LST+dur --> 1987200+1814400

Evaluating ... ...

LFT = 3801600

STEP 3: Convert Result to Output's Unit

3801600 Second -->44 Day (Check conversion here)

FINAL ANSWER

44 Day <-- Late Finish Time

(Calculation completed in 00.020 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

Late Finish Time Formula

Late Finish Time = Late Start Time+Duration of Activity
LFT = LST+dur

What is Late Finish Time?

Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint. For calculating this we use the backward pass; i.e. we will start from the last activity and move back towards the first activity. It is the sum of the late start time and the duration of an activity.

How to Calculate Late Finish Time?

Late Finish Time calculator uses Late Finish Time = Late Start Time+Duration of Activity to calculate the Late Finish Time, Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint. Late Finish Time is denoted by LFT symbol.

How to calculate Late Finish Time using this online calculator? To use this online calculator for Late Finish Time, enter Late Start Time (LST) & Duration of Activity (dur) and hit the calculate button. Here is how the Late Finish Time calculation can be explained with given input values -> 0.000509 = 1987200+1814400.

FAQ

What is Late Finish Time?

Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint and is represented as LFT = LST+dur or Late Finish Time = Late Start Time+Duration of Activity. Late Start Time is the latest point in time when the scheduled activity can begin so as not to delay the project completion date or any constraint & Duration of activity is the total number of work periods required to accomplish the work of the activity.

How to calculate Late Finish Time?

Late Finish Time is the latest point in time when the scheduled activity can finish so as not to delay the project completion date or any constraint is calculated using Late Finish Time = Late Start Time+Duration of Activity. To calculate Late Finish Time, you need Late Start Time (LST) & Duration of Activity (dur). With our tool, you need to enter the respective value for Late Start Time & Duration of Activity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
