Logistics experts Inc (LEI) is a 3rd party logistics (3PL) provider. A 3PL is an organization that manages and executes a particular logistics function, using its own assets and resources, on behalf of another company (

LEI picks up freight from suppliers and delivers it to their clients. Multiple Toyota manufacturing businesses (e.g. TMMI – Toyota Motor Manufacturing Indiana, TMMK) are LEI clients. LEI is headquartered in Atlanta, GA and has a second major location in Toronto, ON. The Atlanta location houses the logistics design group as well as the executive team (total 1,750 people). The Toronto location houses administrative functions such as accounting, HR and corporate services (250 employees). LEI runs cross docks at 6 different locations, 2 in Canada and 4 in the US. The locations are Kitchener, ON, Toronto, ON, Detroit, MI, Atlanta, GA, Lexington, KY and Indianapolis, IN. Cross Docking is the transfer of inward deliveries from the point of reception directly to the point of delivery with limited or no interim storage ( Each cross dock location has administrative staff, cross dock workers and logistics experts (approximately 50 workers/cross dock). There is a leased line between the two major locations and each cross dock is connected back to the HQ through the internet using internet service provided by local ISPs. VPN technology is used to secure the connections over the internet.

LEI owns and or leases a large fleet of trucks (20,000 trucks, 30,000 trailers). 30,000 Truck drivers are on the company payroll. In order to provide process visibility to their customers, LEI must track the movement of each shipment from the moment they pick it up, to the time it is delivered to the customer. The trucks are equipped with GPS devices that communicate with a tracking server over the cellular network. LEI also uses RFID tags on all shipments to achieve process visibility and to provide tracking information to their customers.

LEI’s revenues are currently $2 billion. They expect to double the revenue in the next 5 years through aggressive growth by providing logistics services to more manufacturers in the US and by expanding into the Asian market, particularly China and India.

Dell OptiPlex desktops and Dell Latitude laptops are used for all client systems.

LEI expects 5 nine (99.999%) availability for their enterprise system. Availability of systems is critical since they provide JIT inventory services to their clients with significant liability clauses in their contracts with the clients.
