Non-Productive Time for Each Component given Average Production Time Solution

STEP 0: Pre-Calculation Summary
Formula Used
Setup Time = Average Production Time-(Machining Time+(Number of Tools Used*Time to Change One Tool/Batch Size))
ts = tp-(tm+(Nt*tc/Nb))
This formula uses 6 Variables
Variables Used
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.
Average Production Time - (Measured in Second) - Average Production Time is the time taken to produce a single component out of a lot of produced batches.
Machining Time - (Measured in Second) - Machining Time is the time when a machine is actually processing something. Generally, machining time is the term used when there is a removal of unwanted material.
Number of Tools Used - The Number of Tools Used is the total number of tools used for manufacturing a batch of products.
Time to Change One Tool - (Measured in Second) - Time to Change One Tool is the measure of time it takes to change one tool during machining.
Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
STEP 1: Convert Input(s) to Base Unit
Average Production Time: 10 Minute --> 600 Second (Check conversion here)
Machining Time: 46 Second --> 46 Second No Conversion Required
Number of Tools Used: 3 --> No Conversion Required
Time to Change One Tool: 5 Minute --> 300 Second (Check conversion here)
Batch Size: 2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ts = tp-(tm+(Nt*tc/Nb)) --> 600-(46+(3*300/2))
Evaluating ... ...
ts = 104
STEP 3: Convert Result to Output's Unit
104 Second -->1.73333333333333 Minute (Check conversion here)
FINAL ANSWER
1.73333333333333 โ‰ˆ 1.733333 Minute <-- Setup Time
(Calculation completed in 00.004 seconds)

Go Time to Change One Tool = Total Tool Changing Time/Number of Tools Used
Total Tool Changing Time
Go Total Tool Changing Time = Number of Tools Used*Time to Change One Tool
Cost of Tool given Total Cost of Tools
Go Cost of a Tool = Total Cost of Tools Used/Number of Tools Used
Total Cost of Tools Used
Go Total Cost of Tools Used = Number of Tools Used*Cost of a Tool
Machining Time for one Component using Total Machining Time
Go Machining Time = Total Machining Time/Batch Size
Total Machining Time or Total Machine Time
Go Total Machining Time = Batch Size*Machining Time
Size of Batch given Total Machining Time
Go Batch Size = Total Machining Time/Machining Time
Load or Unload or Setup Time given Total Non-Productive Time
Go Setup Time = Non-Productive Time/Batch Size
Size of Batch using Total Non-Productive Time
Go Batch Size = Non-Productive Time/Setup Time
Total Non-Productive Time
Go Non-Productive Time = Batch Size*Setup Time

Non-Productive Time for Each Component given Average Production Time Formula

Setup Time = Average Production Time-(Machining Time+(Number of Tools Used*Time to Change One Tool/Batch Size))
ts = tp-(tm+(Nt*tc/Nb))

Significance of Non-Productive Time

The Non-Productive Time helps the concerned to determine the resource of the industry being wasted due to time lapse in important but non-profitable processes of the production line. It also helps in determining the required measures to be taken to increase the productivity of the plant which generally includes steps to decrease the Total Non-Productive Cost.
