Size of Batch using Total Non-Productive Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Batch Size = Non Productive Time/Setup Time
N_b = NPT/t_s
This formula uses 3 Variables

Variables Used

Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
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.
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

Non Productive Time: 108 Second --> 108 Second No Conversion Required
Setup Time: 54 Second --> 54 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_b = NPT/t_s --> 108/54

Evaluating ... ...

N_b = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- Batch Size

(Calculation completed in 00.004 seconds)

Managing Non-Productive Time

The reduction of non-productive time is one of the key elements to remain competitive in a fabricating environment. This is usually done by:
1. Control front end processing time
2. Analyze total cycle time
3. Maintain machine cycle time
4. Reduce total order turnaround
