Sigma Alimentos
AS/RS and WMS Case Study

MEAT AND CHEESE ON THE MOVE AUTOMATICALLY
Westfalia Technologies Inc. is currently installing an Automated Storage and Retrieval System (AS/RS) for Sigma Alimentos, Mexico’s top producer of refrigerated and frozen foods, at a new distribution center in Monterrey, Mexico.
A division of Grupo Alfa, Sigma operates one of Mexico’s largest refrigerated distribution networks and leads the Mexican market in processed meat and cheese products, with brands that include Chalet and El Cazo Mexicano. Its products are sold throughout Mexico, the Caribbean, Central America and the US. The company also holds exclusive rights to produce yogurt under the Yoplait brand in Mexico and Central America and to distribute Oscar Mayer products in Mexico.
System Features:
- 2 Storage & Retrieval Machine (SRMs)
- Savanna.NET Warehouse Management System
- 200 linear feet of conveyors
- 4 level racks
- Unique Product: 4 pallet transfer car
The new refrigerated distribution center is Sigma’s first automated warehouse, and utilizes Westfalia’s AS/RS and Savanna.NET® Warehouse Management System (WMS). The Westfalia system includes two Storage/Retrieval Machines (SRMs), 200 linear feet of conveyors and a 30ft. high rack structure with four levels, the first level designated for picking.
According to Gary Frank, V.P. of Automation for Westfalia, Sigma’s needs are met with a system that included a combination of standard and custom design elements. Unique system features include a four-pallet transfer car; the option for manual infeed with depalletizing for case-picking lanes; and an option to have two Satellite® rack entry vehicles on each SRM.
Westfalia’s Savanna.NET® WMS will manage all products as they travel through the distribution center, including order picking. With its modular structure, Savanna.NET is capable of adapting and integrating individual logistics requirements, such as the case picking, SKU organization and order consolidation Sigma requires.
Sigma’s new distribution center will be fully operational in the summer of 2007.
