STEP 1: Convert Input(s) to Base Unit

Batch Size: 2 --> No Conversion Required
Production Cost of Each Component: 11400 --> 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: 3 --> 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

T_np = (N_b*(C_pr-C_t*t_m)-(C_t*N_t*t_c)-(N_t*C_t))/C_t --> (2*(11400-80*69)-(80*3*30)-(3*80))/80

Evaluating ... ...

T_np = 54

STEP 3: Convert Result to Output's Unit

54 Second -->0.9 Minute (Check conversion here)

FINAL ANSWER

0.9 Minute <-- Non Productive Time

(Calculation completed in 00.004 seconds)

Components of Non-Productive Time

1) Setup Time: Time required to prepare the machine, tools, and workpiece for production.
2) Tool Change Time: Time spent on changing worn-out or broken tools.
3) Machine Downtime: Periods when the machine is not operational due to maintenance, repairs, or adjustments.
4) Material Handling Time: Time spent on loading and unloading materials and components.
5) Waiting Time: Time spent waiting for materials, tools, or instructions.
6) Maintenance Time: Time allocated for preventive or corrective maintenance activities on machines and equipment.

Significance

1) Cost Management: Helps in identifying and reducing non-value-added activities, thereby minimizing associated costs.
2) Production Planning: Allows for more accurate scheduling of production runs and resource allocation.
3) Efficiency Improvement: Enables the identification of bottlenecks and inefficiencies in the production process for targeted improvements.
4) Capacity Utilization: Optimizes machine and labor utilization by minimizing downtime and idle time.
