Slot Based Production

Tags: Glossary

A lean manufacturing term used to describe a production system that has been level loaded (Heijunka), with a few slots held open for situations where demand must be met immediately.

What is Slot Based Production?

Slot Based Production is a term commonly used in the field of lean manufacturing to describe a production system that aims to achieve a balance between efficiency and flexibility. In this system, the production process is level loaded, meaning that the workload is evenly distributed over a specific time period. However, a few slots are intentionally left open to cater to situations where immediate demand needs to be met.

The concept of level loading, also known as Heijunka, is a fundamental principle in lean manufacturing. It involves smoothing out the production schedule to avoid peaks and valleys in production volume. By doing so, it helps to eliminate waste, reduce inventory levels, and improve overall efficiency. Level loading allows manufacturers to better plan their resources, optimize production flow, and respond to customer demand more effectively.

In a slot based production system, the level loaded schedule is further enhanced by reserving a few slots for urgent or unexpected orders. These slots act as a buffer, providing the necessary flexibility to accommodate sudden changes in demand. By keeping a small number of slots open, manufacturers can quickly respond to customer requests without disrupting the entire production process.

The reserved slots in slot based production are strategically allocated based on various factors such as the frequency and urgency of demand fluctuations, the capacity of the production line, and the lead time required to fulfill orders. These slots are typically kept at a minimum to ensure that the production system remains efficient and cost-effective.

One of the key advantages of slot based production is its ability to strike a balance between efficiency and responsiveness. By level loading the production process and reserving a few slots, manufacturers can achieve a smooth and predictable workflow while still being able to meet immediate customer needs. This approach minimizes the risk of overproduction or underproduction, leading to improved customer satisfaction and reduced costs.

Furthermore, slot based production promotes better coordination and collaboration among different departments within a manufacturing facility. With a clear and predictable production schedule, teams can align their activities and resources more effectively. This synchronization helps to minimize bottlenecks, reduce lead times, and enhance overall productivity.

In conclusion, slot based production is a lean manufacturing concept that combines the principles of level loading and flexibility. By maintaining a level loaded schedule and reserving a few slots for immediate demand, manufacturers can achieve a balance between efficiency and responsiveness. This approach not only improves resource planning and production flow but also enhances customer satisfaction and reduces costs.
