Innovative solution links front-end ordering with manufacturing to cost- effectively meet customer demand

Aspen Technology, Inc.

By creating a close connection between Westlake's customer service team in Houston, Texas and its manufacturing operations in Lake Charles, LA, the AspenTech solution is expected to generate significant annual benefits. It is already reducing production of off-spec products and helping Westlake maintain inventory levels well below the industry norm.

"AspenTech's supply chain solution enables us to link our customer service managers, plant schedulers and production managers for the benefit of our customers," said Warren Wilder, Vice President of Westlake Polymers. "The technology helps us to provide these key groups with the real-time information they need to optimize production, scheduling and delivery relative to client demand. This improved responsiveness helps us to reduce costs across our internal value chain."

Westlake began implementation in May 2000 and has now rolled out the AspenTech solution in two of its three polyethylene plants. The solution -- which integrates with Westlake's SAP order entry system, its ACTA data warehousing system, and its in-house quality control system -- provides the company with better visibility of customer demand, making more detailed sales and ordering information accessible to its plants.

The availability of more precise demand forecasts allows Westlake to optimize reactor schedules and better manage customer delivery requests. Additional cost savings also stem from more accurate ordering of raw materials, resulting in less surplus stocks.

"Westlake has developed a visionary information technology strategy, integrating its front-end order systems with its manufacturing operations," said Larry Evans, Chairman and CEO of AspenTech. "By using supply chain technology to bring its plants closer to the customer, the company is able to both minimize costs and improve service."

For the past four years, AspenTech has been providing a variety of asset optimization and supply chain solutions to The Westlake Group of Companies, involving Westlake Polymers Corporation, Westlake Petrochemicals Corporation, and The Titan Group, a sister company of The Westlake Group.
