Question:

List the benefit of the cellular layout to Airline Manufacturing.

Airline Manufacturing is a 275,000-square-foot, 100- employee wood component manufacturer supplying upholsterers (e.g., sofa manufacturers), and is located in Columbus, Mississippi. When Judy Dunaway took die helm of the company following her father in 2000, the company had used a batch production system for 40 years. However, the threat of competition led her to start JIT/lean manufacturing. High-run (quantity) products were identified and grouped together if their required sequences of operations were identical. The machines required for each group were located close together in a dedicated cell (flow line). As a result, the amount of WJP inventory' has been cut by more than half, the number of material-handling carts has been reduced from 3,000 to 1,000, and die number of material handlers has been reduced by half. Also, manufacturing lead time is down from four weeks to less than a week.

A high-run product i s part #146-3 843. Consider the production of a 2,900-unit customer order. Before the layout change, batches of approximately 1,000 units were transported from the warehouse to the CNC Router, and from there batches of approximately 380 units were carried, when ready, from one machine to another by two workers using heavy carts. See the Batch Plant Layout diagram, Figure 1, on the next page. These workers returned the empty carts to the originating machine. After the final operation, Dowel, the finished product was transported in batches of approximately 380 units to die Finished Goods Warehouse using forklifts. The total worker-feet of movement using the forklifts (including the return to their origin) was approximately 5,300.

After the layout change, the only transport is by forklifts bringing in and taking out the product. The total worker-feet of movement using the forklifts has remained at approximately 5,300. However, the amount of machine-to-machine material handing has been greatly reduced because the machines are located close to each other, See the Cellular Layout, Figure 2, on the right. Due to elimination of delays waiting for material handing, the company can make the 2,900 units customer order in one day whearas it used to take six days.
