Maximum safety, efficiency and productivity are essential for the profitable operation of chemical plants. But, making decisions to drive these goals is not always clear cut because there are far-reaching consequences--The Department of Justice has estimated that nearly half of the 15,000 chemical plants in the US have the potential to affect upwards of one thousand people in the surrounding area. The EPA estimates that over 100 of those plants could affect more than one million people. The most advanced chemical companies are able to evaluate alternatives and their costs through optioneering. Optioneering makes it possible to explore alternatives by using simulation-based analysis to find the best solutions to problems and reduce risk.
