Innovative Integration between AspenTech and Microsoft Applications Extends the Value of Simulation Technology

03/07/06
Aspen Simulation Workbook(TM) Integrates AspenTech's Rigorous Simulation Technologies and Microsoft(R) Excel, Creating New Opportunities to Leverage Process Models

CAMBRIDGE, Mass.--(BUSINESS WIRE)--March 7, 2006-- Aspen Technology, Inc. (NASDAQ: AZPN) today announced the availability of an innovative application that enables customers to significantly increase the value of their investment in simulation technologies. Aspen Simulation Workbook provides integration between AspenTech's process simulation applications - such as Aspen Plus(R) and Aspen HYSYS(R) - and Microsoft Excel, with no programming expertise required. The integration creates new opportunities for companies to use process models for operational decision making and to streamline their conceptual design workflows.

To allow customers to experience the capabilities provided by Aspen Simulation Workbook, AspenTech is currently running a free web-based trial program. Further details about the program can be found at www.aspentech.com/sws.

Aspen Plus and Aspen HYSYS, along with Excel, are the most commonly used tools in process engineering, both for supporting plant operations and in process design. Integrating AspenTech's simulators with Excel opens up a new range of possibilities for users who are not experts in simulation to make use of process models in plant operations and increase the quality and speed of conceptual design work. Aspen Simulation Workbook is built on the Aspen Open Simulation Environment (OSE)(TM) which is the integration environment that allows users to share the same internal and third-party engineering and operations models.

Some of the key capabilities made possible by Aspen Simulation Workbook include:

  • solving plant operating problems by creating simple Excel-based user interfaces to rigorous simulation models
  • reducing the effort to maintain and validate plant process models by making it easy to input real plant data
  • automating data transfer between simulation applications and Excel-based engineering tools, such as costing or equipment design programs.

The value delivered by Aspen Simulation Workbook has already been recognized by a number of leading companies. ABB Engineering Services, which provides simulation, energy, environmental and safety consultancy services to the process industries, has selected the product to improve the execution of simulation projects that require the use of multiple applications, including AspenTech's simulation products and other design tools.

"Aspen Simulation Workbook has enabled us to integrate Aspen Plus and Aspen FIHR(TM) with a third-party design program without the need to develop custom software," said John Martin, Senior Process Consultant, ABB Engineering Services. "The project requires data to be repeatedly transferred between the three applications. Aspen Simulation Workbook allows us to connect them together with a simple, off-the-shelf solution that is easy to use and maintain."

"Our major customers already garner tremendous value from our process simulation applications," said Blair Wheeler, Senior Vice President, AspenTech. "Aspen Simulation Workbook enables those customers to extend that value, and to make it accessible to a broader range of non-expert users. This creates significant new potential to use process models as part of day-to-day operational decision-making, as well as increasing efficiency and productivity during conceptual design."
