Process knowledge management, metrics

Therefore, in this approach, we develop Risk Model III as a reformulation of Risk Model II by employing the mean-absolute deviation (MAD), in place of variance, as the measure of operational risk imposed by the recourse costs to handle the same three factors of uncertainty (prices, demands, and yields). To the best of our knowledge, this is the first such application of MAD, a widely-used metric in the area of system identification and process control, for risk management in refinery planning. 

Finally, management must cultivate a positive process safety culture that will inspire people to support process safety and metrics efforts. Perhaps the largest enticement to implementing new or revised process safety metrics is the knowledge that the results will be handled seriously and appropriately, with proper remedial action taken when necessary. A positive and mature safety culture promotes open dialogue on issues, discusses improvement strategies by engaging a broad array of employees, and will not tolerate deviation from established procedures.
