Organization Is Key for Just-In-Time Manufacturing
Andy Owen | Industrial Maintenance & Plant Operation
The concept of just-in-time was developed in Japan in the 1960s and '70s. The concept is that a business holds no stock and relies on deliveries of raw materials and components to arrive just in time to manufacture and fulfill a customer order. These deliveries arrive on the factory floor when required. This approach means that stock does not build up in the warehouse, which saves space and reduces the amount of capital held in the stock. However, it does mean that there is high pressure on manufacturers to deliver the stock quickly, and on plant managers to ensure there are no delays.
To successfully manage a just-in-time system, it is important for businesses to follow key processes. M. Sepheri, a JIT expert, published a methodology for businesses to follow. Sepheri considered housekeeping a top priority. He said that they should consider the physical organization and discipline of their plant, and that it should have a compact layout.
To maintain this orderly process, firms need to ensure that all of the steps in getting the product from the factory to the customer are efficient and do not waste any time or resources. A key step in this process is how businesses physically move goods. Traditionally, companies use forklift trucks or high levels of manual labor to move things. However, this is a slow process that can hinder the JIT methodology.
Traditional equipment, such as a crane or forklift, is fine for use at the periphery of a factory, but struggles as it gets closer to the production lines, where narrower walkways can post a safety risk to pedestrians. This means that more manual labor is required, which is not great if you're trying to roll out a JIT system. Instead, plant managers can use electric tugs, controlled by a pedestrian, to move heavier loads safely and much more quickly.
Congested walkways also delay workers' movements, if they have to wait for their path to clear or for a trained crane or fork lift operator to move the product.
By reducing safety hazards and reducing the amount of manual handling that workers do, businesses can reduce the potential of injury and subsequent sick leave. This allows the company to reduce labor costs and improves the company's safety record.
By following these processes and using electric tugs to move their products, companies can maximize the efficiency and speed of their production line to create an effective just-in-time process.
