This is a method for use in automated screening of tickets for plant protection based on negative feedback from past performance. In particular this invention provides an automated screening process that takes a dig ticket address from a ticket request and correlates it to known cable locations to determine which ticket dig addresses are too close to the buried fiber. This is done using a method that balances the risk of extra labor charges due to a Type I error with the risk of costs associated with a cable cut due to a Type II error.
