Experiences from an industry-university study on control benefits

A proper benefits study achieves more than simply estimating potential econ omic improvement. it provides the basis for variable selection. control des ign, equipment sperification. and implementation strategies. General approa ches for such studies are available but are not widely employed for two maj or reasons, lack of training and a mistaken idea that the study adds substa ntial cost to project. We review currently available methods and offer a pr oposal for improvements by focusing these methods on specific processes.
