Manufacturers lack the economic tools to properly perform maintenance procedures to increase
manufacturing reliability while reducing system energy consumption. A return on investment strategy is
developed to provide plant managers with a quantitative method to optimize the maintenance actions
that lead to the largest return on investment. Over the long term, this energy economic analysis results in
the largest decrease in energy costs for a manufacturing facility. A control methodology is developed to
increase profits on a daily basis by inserting energy opportunity windows at various machines thus
reducing energy consumption with minimal production impact. A simulation case study is performed to
validate the return on investment strategy and to test the control methodology's impact on the overall
profit of the facility
