<p>A method and apparatus for controlling the operating speed of a papermaking facility is disclosed. It includes determining a desired operating speed that is dependent on at least one economic variable. The variables vary with the operating speed. Also, the operating speed is adjusted (if necessary) in response to the determination. Preferably the control is closed loop and includes determining a current operating speed and comparing the current operating speed to the desired operating speed. The operating speed is controlled in response to the comparison. The economic variable is preferably a cost of manufacturing, and/or manufacturing inflows, and/or manufacturing outflows. Also, a method and apparatus that determines the effect of one or more business transactions on the economic efficiency of the production of products in a paper manufacturing facility is disclosed. The economic efficiency is dependant on one or more economic variables that vary with operating speed. The current economic efficiency of the facility is obtained along with information on the business transactions that affects the economic variables. The economic efficiency of the facility with the proposed transaction, leaving the remaining variables constant is calculated. Then, the result is displayed to the end user.</p> |
