Recently I've developed a multivariable control strategy for scheduling control at the Valero Aruba Refinery by setting up the project management tool Primavera P4 program for planning and scheduling standardization, using project codes, activity codes, Refinery resources, layouts and reports. Through these efforts the scheduler can schedule its project in a timely matter and customize any type of reports before, during and after a Turnaround or Project for field execution team or management team.
