STEP 0: Pre-Calculation Summary

Formula Used

Non Productive Time = (Batch Size*(Production Cost of Each Component-Cost of A Tool*Machining Time)-(Cost of A Tool*Number of Tools Used*Time to Change One Tool)-(Number of Tools Used*Cost of A Tool))/Cost of A Tool
NPT = (N_b*(C_pr-C_t*t_m)-(C_t*N_t*t_c)-(N_t*C_t))/C_t
This formula uses 7 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.
Production Cost of Each Component - Production Cost of Each Component is the total amount that it takes to produce a single component from scratch.
Cost of A Tool - The Cost of a Tool is simply the cost of one tool being used for machining.

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.

STEP 1: Convert Input(s) to Base Unit

Batch Size: 2 --> No Conversion Required
Production Cost of Each Component: 15000 --> No Conversion Required
Cost of A Tool: 80 --> No Conversion Required
Machining Time: 1.15 Minute --> 69 Second (Check conversion here)
Number of Tools Used: 4.16129 --> No Conversion Required
Time to Change One Tool: 0.5 Minute --> 30 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

NPT = (N_b*(C_pr-C_t*t_m)-(C_t*N_t*t_c)-(N_t*C_t))/C_t --> (2*(15000-80*69)-(80*4.16129*30)-(4.16129*80))/80

Evaluating ... ...

NPT = 108.00001

STEP 3: Convert Result to Output's Unit

108.00001 Second -->1.80000016666667 Minute (Check conversion here)

FINAL ANSWER

1.80000016666667 ≈ 1.8 Minute <-- Non Productive Time
