Total Non-Productive Time Solution

STEP 0: Pre-Calculation Summary
Formula Used
Non Productive Time = Batch Size*Setup Time
NPT = Nb*ts
This formula uses 3 Variables
Variables Used
Non Productive Time - (Measured in Second) - Non Productive Time is the total time wasted in setting up the machine or workpiece for a particular process.
Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
Setup Time - (Measured in Second) - Setup Time of each component is the time required to load/unload the workpiece and position the tool for production for one component.
STEP 1: Convert Input(s) to Base Unit
Batch Size: 2 --> No Conversion Required
Setup Time: 54 Second --> 54 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
NPT = Nb*ts --> 2*54
Evaluating ... ...
NPT = 108
STEP 3: Convert Result to Output's Unit
108 Second --> No Conversion Required
FINAL ANSWER
108 Second <-- Non Productive Time
(Calculation completed in 00.020 seconds)

Total Non-Productive Time Formula

​LaTeX ​Go
Non Productive Time = Batch Size*Setup Time
NPT = Nb*ts

Why do we need to reduce Non-Productive Time ?

Non-Productive Time is the time actually being consumed in processes that result in no benefit to the Production House. If these processes are optimized, then the time available for actual production increases, resulting in more profit for the day.

How to Calculate Total Non-Productive Time?

Total Non-Productive Time calculator uses Non Productive Time = Batch Size*Setup Time to calculate the Non Productive Time, The Total Non-Productive Time is defined as the total time taken to loading/unloading the workpiece and repositioning the tool for the manufacturing of a unit product. Non Productive Time is denoted by NPT symbol.

How to calculate Total Non-Productive Time using this online calculator? To use this online calculator for Total Non-Productive Time, enter Batch Size (Nb) & Setup Time (ts) and hit the calculate button. Here is how the Total Non-Productive Time calculation can be explained with given input values -> 108 = 2*54.

FAQ

What is Total Non-Productive Time?
The Total Non-Productive Time is defined as the total time taken to loading/unloading the workpiece and repositioning the tool for the manufacturing of a unit product and is represented as NPT = Nb*ts or Non Productive Time = Batch Size*Setup Time. Batch Size is the count of similar kinds of products to be manufactured & Setup Time of each component is the time required to load/unload the workpiece and position the tool for production for one component.
How to calculate Total Non-Productive Time?
