BREA, Calif.--(BUSINESS WIRE)--Sept. 24, 1998--Simulation Sciences Inc. (SIMSCI)(Nasdaq:SMCI) Thursday announced the signing of a perpetual contract with Philip Morris Holland.

The agreement covers license and engineering service fees for SIMSCI's AIM-AT Suite, a Windows NT-based enterprisewide information management and control system for the process and discrete manufacturing industries.

The AIM-AT Suite is based on a new 32-bit distributed architecture incorporating the latest industry standards, using the client/server model and object-oriented programming techniques. The AIM-AT Suite features the AT-Historian database and information dispersal engine; gateways for real-time data transfer from plant floor data sources; and OLE, AtaGlance/IT and ODBC connectivity agents.

Other product components include an add-in for Microsoft Excel, data analysis visualization tools for historical and real-time information, a software development kit (SDK) for C and C++ applications, and various configuration tools.

Commenting on the contract, Paul van den Boom, the IS project leader at Philip Morris's Bergen-op-Zoom, Netherlands, facility, said: "We've been using SIMSCI's AIM-Supervisor software within our primary operations for several years and continue to be pleased with its excellent performance. Our secondary operation required state-of-the-art technology under a Windows NT environment.

"After an extensive evaluation, the AIM-AT Suite was chosen for its flexibility, user-friendliness and client/server and Windows NT-based technology. The program fits well within our site infrastructure and SIMSCI's commitment to build a Digital BaseStar gateway will give us the capability to collect significant data from our high-speed manufacturing and packing machines," van den Boom added.

Larry Gozzard, SIMSCI's president, said: "We are pleased with Philip Morris' decision to use SIMSCI's AIM-AT software. We look forward to strengthening our partnership by providing them with best-in-class PIMS software solutions."
