FlightSafety International is the world's leading provider of aviation training and manufacturer of full flight simulators, visual systems and displays. With more than 40 Learning Centers, worldwide, 1,800 instructors, 3,000 courses on 135 aircraft types, FlightSafety International provides over a million hours of training each year on a wide variety of aircraft types from fixed wing to helicopters, used in corporate aviation, by commercial airlines, and government and military agencies. Using over 300 simulators to train customers in over 167 countries, FlightSafety International has one mission: Safety.
The Broken Arrow, OK manufacturing facility was moved to a new 375,000 square foot facility within the same city limits. This new facility allowed FlightSafety International to improve efficiencies and expand capabilities. With the capacity to produce up to 19 simulators at once, the stockroom keeps busy filling orders for the production line.
Component parts are picked on a daily basis and sent to kitting where the kits are stored until manufacturing is ready. With demand on the rise, the stockroom needed a more efficient and controlled environment. "Component parts and kits were stored in cardboard boxes on shelving, making order fulfillment a time consuming, labor intensive process and inventory susceptible to shrinkage," says Mike Halsey, Director of Manufacturing and Material Management. The move to the new facility was the perfect opportunity to improve the stockroom.
An Automated Solution
The installation of four, 36' tall Shuttle XP Vertical Lift Modules (VLMs) reduced the footprint of the component and kitting areas in the new facility from roughly 6,454 square feet to 960 square feet, an 85% floor space savings! The VLMs are used in two work zones. The first zone utilizes two of the VLMs for component parts. Integrated with pick to light technology, inventory management software and a 10 position batch station to increase productivity and improve inventory control. The second zone uses the other two VLMs integrated with pick to light technology and a 10 position batch station as buffer storage for kitting.
Inventory Control Reaches New Heights
Previously with the shelving system, there was unlimited access to inventory. This area was not secure and without inventory personnel available after hours to monitor parts movement, inventory parts would come up missing, creating an untraceable loss in inventory. "After implementing the Shuttle VLMs, inventory is much more accurate," says Halsey, "The VLM operators are given access to the machine, but each transaction is now monitored and recorded electronically in the inventory management software."
The old shelving system required seven people in the components area and seven people in the kitting area. Since installing the Shuttle VLMs, only one person is required in the components area and one person in the kitting area. With labor reduced by 86%, other workers have been reassigned to different areas of the warehouse to increase efficiencies. While the two workers that remain in the Shuttle VLM area are picking and kitting for the majority of the day, time is also spent working on other tasks such as inventory counts and replenishment orders. "Time spent walking and searching for parts and kits has been eliminated, allowing our staff to spend time on other important tasks such as replenishment," says Gene Harvey, Inventory Control Supervisor.
Accuracy Takes Off
A primary catalyst for implementing the Shuttle VLMs was the ability to increase accuracy. "The opportunity for human error was affecting our pick accuracy and impacting manufacturing," says Harvey. In the event of a mispicked part, not only did the incorrect part make it to the manufacturing floor in the first place, that part needed to be received back into the shelving area while the new part was picked and delivered to the production line. Further, the incorrect part was often left on the shop floor for quite a while until it was eventually returned. "When the wrong part makes it to manufacturing, it used to cause a shutdown - with the VLMs that doesn't happen now," says Harvey.
With the Shuttle VLMs, there is limited to no opportunity for error. Integrated with pick to light technology, the Transaction Information Center (TIC) directs the operator throughout the picking processing. "Accuracy is at 99.9% - up from the mid 90%'s," says Harvey.
Old Methods Are Cancelled
Previously, all component parts were stored on shelving and in cardboard boxes. "The amount of travel time one person would spend walking and searching for a part was time wasted," says Harvey. A paper pick ticket would tell the pickers what parts to pick for each order. The workers would walk the entire warehouse to collect parts for the order. Once all of the parts were picked the order would be delivered to the kitting area.
The kitting area would receive the order and store it as a kit in buffer storage shelving. Upon production request, kits would be pulled and assembled and then sent to production. In this manual process, parts were touched and moved multiple times before they made it to the production line, leading to inefficiencies.
VLMs Speed Processes
Just over 8,000 SKUs were moved from the old shelving area into the two new Shuttle VLMs dedicated to component parts. The other two VLMs were dedicated to buffer storage for kits. "There is now a continuous flow from the component parts to kitting and down to production," says Halsey.
The planning department generates orders in the MRP system. The orders are then sent to the inventory management software. Once the orders are loaded, the picker in the component area can start filling orders. Picking priority is based on the kit due date; therefore the most urgent kits are picked first.
There is a 10 position batch station located next to the Shuttle VLMs allowing the operator to pick up to 10 orders at a time. The operator selects up to 10 orders and assigns a tote on the batch station to each individual order, and then with the touch of a button the picking process starts. The inventory management software tells the Shuttle VLM which part needs to be picked, pulling the appropriate tray from the machine. The tray is delivered via an extractor that runs up and down the middle of the unit. Delivered to an ergonomic height, the TIC lights direct the operator to the appropriate part location, displays the part number and the quantity to pick. Once the first part in the order is picked, the operator confirms the pick with a task complete button, or with the VLM confirmation bar. A bar coded label is printed and the operator bags and tags the part for movement down the conveyor to the kitting VLMs. This provides positive identification of material throughout the entire process and ensures the appropriate part has been picked and kitted.
Each position on the batch station is fitted with a put light that directs the operator in which orders to put the parts picked from the VLM. While the operator distributes the parts among the orders in the batch, the VLM is delivering the next part to the access opening, eliminating wait time and maximizing productivity. As orders are completed they are sent to kitting via conveyor.
Upon arrival at kitting, the operator bar code scans each tote, placed at one of the ten batch light positions, and the VLMs presents a tray and uses the TIC to direct the operator to the exact location on the tray to store the kit. The kit can remain in the VLM buffer storage for up to 60-90 days. The production floor sends a request to kitting to pull the appropriate kit number and the operator retrieves the kit requested from the Shuttle VLM and delivers it to manufacturing.
"The machines are highly reliable with almost 0% downtime. The service team has an excellent response time when we've required it," says Halsey.
Leaning Out Waste
The previous shelving system was not efficient; resources were being wasted to complete daily tasks. "Valuable time and manpower was wasted in the previous system, eliminating that waste was part of the justification for this project," says Halsey.
Keeping Up With Demand
The Shuttle VLMs have improved stockroom processes and efficiencies, saving time and increasing inventory accuracy. "In order to meet the demand on the shop floor, we would have had to add more people - we couldn't have kept up otherwise. The Shuttle VLMs solved that problem and allowed us to increase productivity," says Harvey.
