Optimization Systems Associates

Bandler founded OSA in 1983 to commercialize optimization methodology and algorithms which he and his colleagues had developed. OSA's first major project was the reengineering of key software for simulation and optimization of waveguide multiplexers for satellite communications under contract to COM DEV International.

In the 1980s OSA contributed optimization methodology and algorithms to EEsof’s early microwave CAD software Touchstone and Libra, and then reengineered Compact Software’s principal software products SuperCompact and Microwave Harmonica.

OSA implemented a yield-driven CAD and optimization capability for Raytheon Research Division in 1985. OSA was then subcontracted by Compact Software Inc. as part of the Raytheon/Texas Instruments Joint Venture MIMIC Program within the U.S. Department of Defense.{{cite magazine |author=E. D.
