Pitch Time and Pitch Diagram

 Pitch Time & Pitch Diagram

Pitch Time –

Pitch time is nothing but average time per operations i.e. ratio of the SAM (Standard Allowed Minutes) to the number of operations. Pitch time is mainly used by the industrial engineer (I.E.) for the purpose of balancing the production line. It may be calculate in minutes or seconds as per requirement.

Pitch Time = SAM / Number of operations

For Ex. 

Let time required to make one full sleeve formal shirt be 30 minutes and number of operators are 20, then as per formula, 

Pitch Time = 30 / 20 = 1.5 minutes or 90 seconds

90 seconds will be the pitch time. So the operations requiring less than 90 seconds to do a it will not need more operators and those requiring more than 90 seconds may need to have more than one operator.

Pitch Diagram –

Graph plotted with SAM on Y-axis and operations on the X-axis is called as the pitch diagram e.g. it is SAM v/s operations graph, including pitch time. It clearly shows how much operation time varies as compared to average time i.e. pitch time. Using this we can put accurate number of operators for various task as per need is concerned.

• Benefits of the pitch time

1. Main application is to balance the production line.

2. Help to draw pitch diagram.

3. Help in identifying critical operations.

4. Making arrangements of operators as per operations.

5. Identify the bottleneck and help to remove it.

6. Helps in method study and time study.
