The story of Tri-Pacific Software, Inc. begins with a group of software development and design engineers who came together in Tri-Pacific Consulting Corporation. They worked with the Software Engineering Institute (SEI) to promote Rate Monotonic Analysis (RMA), a powerful software engineering method. In 1994, working in conjunction with the University of Illinois at Urbana-Champaign, they created the PERTS product, a modeling and prototyping tool which utilizes RMA. That was followed by PERTS*Sim, a discrete event simulator. In 1998, the group founded Tri-Pacific Software, Inc. to provide real-time embedded systems solutions to the software industry. In 1999, Tri-Pacific Software introduced its RAPID suite of tools for real-time scheduling. In this suite, PERTS and PERTS*Sim are being re-engineered to use JAVA for a GUI front-end, making the programs more versatile and platform independent. The product names have been changed: PERTS is now RapidRMA.
