The criterion for the Next Higher Response Ratio (HRRN) is the Response Ratio (RR). It is calculated as RR = (wait time + burst time) / burst time
HRRN not only supports the shorter process, but also limits the waiting time of the longer process. The next highest response routine (HRRN) is a non-preventive discipline, similar to the following shortest work (SJN), in which the priority of each job depends on its estimated time of execution and also Time you've been waiting for. Jobs gain a higher priority the longer they wait, which prevents indefinite postponement (starvation process). In fact, jobs that have spent a lot of time hoping to compete against those who are estimated to have short run times.
