Unit 4 JIT and Lean Production Contents Development of Materials Management System Push System Pull System Just-in-time Logistics The Agile Supply Chain Competing in Volatile Markets Development of Materials Management System Push System Material is pushed from the production facility through distribution until the product reaches the customer based on forecast or schedules. Pull System In a Pull system, an order from a customer generates an order from the DC, which triggers production run to replenish the plant warehouse. Pull System Benefits Reduced safety stock and system-wide inventory levels No stock transfers between DCs are required to cover regional demand variability Direct shipments from the manufacturing plant to the customer Liabilities Larger on-site manufacturing warehouses Reduced customer satisfaction from slower order fill time Higher transportation costs as shipments from manufacturing are less full and more frequent Pull System Pull System Pull System A hybrid approach of both systems requires storing slower-moving items in a smaller warehouse at the plant while pushing truckload quantities of more popular items to the DCs. Just-in-time Logistics Just-in-time Origin JIT is a manufacturing/delivery process where a minimum of goods are kept in stock and items are planned to arrive precisely at the time they are required for use or dispatch. Henry Ford described essentially the same process, although it wasnt then named, in his autobiography My Life and Work in 1922. Toyota named the process in the 1950s and it spread to the US and UK in the 1970s. Just-in-time Logistics Waste and Variability Reduction Waste is anything that does not add value from the customer point of view. Faster delivery, reduced work-in-process, and faster throughput all reduce waste. JIT systems require managers to reduce variability which results in less waste.
