Optimising the Selection of Metal Cleaning Processes or Cleaning Agents Using Desirability Functions

SUMMARY

It is suggested that the use of desirability functions offers a formalised and consistent means of taking into account both judgemental and numerical factors in the selection of the best process or agent for a particular application. An illustration of the use of desirability functions is given in the selection of a solvent cleaning process for decontaminating components intended for service in oxygen-enriched atmospheres. Final selection is made using a criteria matrix of factor/response desirabilities.
