Waste Management, Inc.

Waste Management, Inc.(WM) is North America's largest waste collection company. Two-thirds of WM revenue is from waste collection services: operational efficiency gained by addressing the needs of the fleet directly impacts the bottom line. Institute of Information Technology, Inc. was contracted to deliver WasteRoute™, a comprehensive route management application that took into account the specific routing considerations of WM: time windows, multiple vehicle disposal trips, and vehicles with varying capacities and service capabilities. The benefits of the system include reduced operating costs, improved customer service and appropriate pricing. The routing solutions of this system were gradually deployed across the nation beginning March 2003 with a net effect of 984 fewer routes at the end of 2003 . WM anticipates $44 million in annual savings in 2004 using WasteRoute™.
