New Castle Building Products has reduced its fleet mileage by approximately 25,000 miles annually using Descartes Systems Group's (NASDAQ: DSGX) route planning and execution solution, according to a company announcement.

The New York-based distributor of exterior building materials replaced manual planning with data-driven routing to lower fuel consumption and costs while improving delivery performance. New Castle operates across six northeastern states including New York, New Jersey, Connecticut, Massachusetts, Pennsylvania, and Maryland.

"Before Descartes, route planning was much more manual and decentralized, making it difficult to consistently optimize deliveries across locations," said Keith Haskell, COO at New Castle Building Products. "With Descartes, we've been able to take approximately 25,000 miles out of our routes annually while improving delivery reliability."

The Descartes platform optimizes routes based on delivery windows, vehicle capacity and traffic conditions. The solution enables centralized dispatch operations and provides visibility for fleet performance monitoring.

New Castle Building Products, established in 2002 with roots dating to 1910, operates 24 locations serving commercial and residential roofing markets. The family-owned company distributes building materials throughout the northeastern United States.

Descartes Systems Group provides logistics technology solutions connecting shippers, carriers and logistics service providers on its Global Logistics Network. The company's platform manages domestic and international shipments, transportation payment, customs compliance and regulatory processes.
