Security personnel time is assigned to a store property by generating an incident score based on a probability of an incident occurring on a store property. A set of ranges of incident scores, each range being associated with a number of hours of security personnel time, are retrieved from computer memory. A range of incident scores in the set of ranges of incident scores that the generated incident score falls within is identified and an associated number of hours of security personnel time is retrieved. Security personnel time is assigned to the store property using a processor based on the number of hours of security personnel time retrieved for the identified range of incident scores.
