What is run and rate in production?
Run at rate in production plays a key role. Today I will introduce to you what is run at rate.
Details
The application of run at rate in production management is mainly reflected in the verification and evaluation of the production process to meet the forecast demand and meet the conditions for mass production. The core purpose of Run and Rate is to confirm whether the people, machines, materials, methods, and environments of a production process have met the QCD indicators (quality, cost, and delivery time) defined by mass production.
Definition and calculation method:
The production takt time refers to the ratio of the total effective production time to the number of customer requirements within a certain length of time. The specific calculation formula is:
[ T = \frac{Ta}{Td} ]
Wherein, (T) is the production takt time, (Ta) is the available working time (excluding rest time and all expected downtime), and (Td) is the number of customer requirements.
Importance of Run at rate
Confirm the production takt: The core purpose of Run at rate is to confirm whether the production line capacity can meet the forecast demand. Through the run at rate, it is possible to evaluate whether the actual production capacity of the production line matches the forecast demand, thereby ensuring the stability and efficiency of the production process.
Quality control in the PPAP (production part approval process), run at rate is an important input condition. Through the run at rate test, quality control in the production process can be ensured and the production of defective products can be reduced.
Demand regulation: The production rhythm reflects the regulatory effect of demand on production. When demand changes, the rhythm will also change, ensuring that the production process can flexibly respond to market changes.
Case
In General Motors, run at rate is called GP-9 and is one of the sixteen steps in product development. General Motors measures run at rate 8 weeks before PPAP approval to ensure that the adjustment of production plans and the acceptance and adjustment of equipment can proceed smoothly.
Through the application of run and rate, enterprises can better manage the production rhythm and ensure the efficiency and stability of the production process, so as to meet the predicted needs of customers and improve overall production efficiency and product quality.
