Production based on PULL method

The application of a pull system allows the start of a new production process only when there is a demand for the product / component from the subsequent production process. The initial signal to the last production process is the customer's order.

​

The traditional approach (push) causes, among other things:
- High production lead times
- Use of machines at their capacity (regardless of demand)
- Minimization of the number of changes
- Large batches and surplus to cover quality defects
- High Stock
- Material waiting queues at machines and stations
- Difficult production control
- High degree of defectiveness and long detection times
- No balancing of processes or machines
- No synchronization of operations between components

The PULL system surfaces problems and forces solutions to be generated:
- Small batch sizes
- Reduction of exchange times
- Minimization of stoppages due to breakdowns. Trend to TPM
- Reliable and integrated providers
- Minimum stocks
- Adequacy of components. Streamlined access to them
- Quick detection of quality problems
- Short lead times
- Short customer response times, improved compliance level
- Elimination of waiting
- Optimization of process control and information flow
