Vertical Lift Modules Save Space and Improve Efficiency at ExpressJet Maintenance Facility Spare Parts Storage Picking slow and medium movers, saves space and increases efficiencies.
Welcome to our "Customer Overview" series of videos. Today Sapient Automation is featuring how ExpressJet of Newark, New Jersey handles their slow to medium moving spare parts inventory.
International Airport's new approach to storing service parts has reduced the amount of space required by traditional shelving, and has helped that operation more efficiently handle slow and medium moving inventory items.
The facility stores a wide range of parts for aircraft service and maintenance, from small fasteners to large air valves. In order to reduce the amount of floor space required for parts storage, and to improve part retrieval efficiency, ExpressJet installed two Vertical Lift Modules, or VLMs, to replace bays of shelving.
The VLMs, which are now being sold and serviced by Sapient Automation as the Viper VLM, were originally purchased and serviced by another organization (under the Power Column 2 brand). Sapient Automation now has the exclusive rights to sell and provide factory replacement parts and service to this VLM in North America.
The Viper VLM is an enclosed high-density storage and retrieval system that consists of two columns of trays in the front and in the back with a robotic extractor that delivers trays to an ergonomically positioned work counter. Vertical Lift Modules take advantage of unused overhead space to reduce the amount of floor space required by traditional shelving by up to 85%. "We placed our slow to medium movers, those parts that we don't retrieve on a regular basis for service and maintenance jobs, in the VLMs and kept our fast moving items, along with just a few bulk items, on the remaining shelving," With slow and medium movers, retrieval velocity is low, but the number of SKUs is large. This strategy helps dramatically reduce floor space by maximizing otherwise wasted vertical height and helps eliminate the walking and searching otherwise required when using shelving.
By analyzing Express Jet's inventory by size, velocity and value it is easy to create classes of items and determine the proper slow to medium moving items to store in the VLM, Likewise, it is easy to then configure the VLM's trays and storage strategy to accommodate every inventory class.
"There are approximately 3,000 SKUs in the two VLMs, 2,000 parts in one and 1,000 in the other. They are divided that way so that the larger, heavier parts are located in one unit and the smaller parts in the other to optimize the storage efficiency of the units." A Viper VLM comes with the ability to designate specific storage locations or to use the unit's optimization program. To optimize the storage cube of the VLMs, a dynamic tray height sensor automatically scans and optimizes storage density every time a tray is stored in the unit. The VLM's control, automatically directs every tray to the least amount of vertical space possible necessary for storage.
"The enclosed design of the VLMs also helps maintain the cleanliness of the parts more effectively than using the shelving, since these parts are slow to medium movers and stay on the shelves longer than faster moving parts. Next to space savings, cleanliness has been the biggest benefit." The side by side VLM configuration allows thousands of parts to be presented at the pick window in seconds. The modular design of the VLM also proved beneficial to the organization when it moved its operations, including all of its inventory and the VLMs, from one storage facility to another in 2004 to 2005. The VLM can be disassembled and reassembled and made shorter or taller. This makes moves such as this less costly and more efficient. Likewise, the VLMs can change to reflect an organization's current business requirements.
At the ExpressJet maintenance facility, all parts stored in the VLMs are labeled with a location number. To retrieve parts, operators key in the location number using the touch screen controls on each unit. The VLM automatically delivers the tray containing the part to the work counter.
"The Inventory levels are monitored by the software program... We have established minimum and maximum levels and we keep track of the levels through management reports." Vertical Lift Modules have helped ExpressJet reduce the amount of space required for storing a wide range of maintenance parts with a varied range of sizes, weights and shapes while providing a more efficient way to handle slow and medium moving parts retrieval.
