Optimization

Introduction Optimization is the process by which APS creates a minute-by-minute schedule by assigning Activities to Resources at particular times according to all specified constraints, Release Rules, Optimize Rules and custom rules. If using the MRP option, Optimize also includes the process of comparing demands to supplies and creating Jobs or Purchase Orders to satisfy […]

Buffer Management

Introduction Buffer Management is the practice of using buffers to account for process variability. Monitoring time buffers enables planers to focus on Jobs that are at risk of critical delay which can impact on-time delivery and possibly starve Drum Resources. The Buffer Management Workbench is the primary tool to assist in monitoring risky buffer penetration. […]

Drum-Buffer-Rope Scheduling

Introduction This is the Theory of Constraints method for scheduling and managing operations that have a consistent internal constraint or capacity-constrained resource. In “Drum-Buffer-Rope”, the “Drum” is the consistent constraint that sets the pace of the rest of the non-constrained Resources. The Drum limits the amount of Throughput for the company. The “Buffer” is a […]

Release Rules

Introduction Release Rules determine how Manufacturing Orders are released for scheduling during an Optimization and therefore supercede the Optimize Rules (which come into play when choosing between released MOs that are in queue). Key Concepts Each Manufacturing Order is prevented from starting to schedule until it is “released”. APS can be configured to release Manufacturing […]

Optimize Rules

Optimize rules are used to create schedules that implement the scheduling objectives for your business. That is, when an optimization is performed, APS’s optimization engine allocates resources and materials according to the preferences defined by the rules in use. For example, APS can optimize based on increasing on-time delivery and utilization or on reducing costs […]
