Production Scheduling Process

What is Production Scheduling?

Production Scheduling is the process of allocating production activities to the best production resource, at the best time in the best sequence and in the best quantity.

Scheduling is a key factor in calculating OEE.

Scheduling Considerations

Generating an optimal production schedule requires numerous data inputs. Fortunately these data inputs are generally available in the Manufacturing Execution System (MES).

Examples of this data includes:

  • equipment capacities
  • equipment capabilities
  • crew availability
  • material availability
  • waste
  • transition (changeover) duration
  • maintenance schedules
  • preventative maintenance requirements
  • Work In Progress (WIP) etc

Production scheduling is a challenging exercise that OpMetriks can help to solve.

Scheduling and OEE

Production Scheduling has a dual impact on plant performance.

Firstly, OEE uses Scheduled Availability (and therefore Scheduled Downtime)  as a primary input to the OEE calculation. Refer to the calculations here.

Secondly, and more importantly, consider the difference between a good, or optimal, schedule compared with a sub-optimal schedule. Both will deliver a similar OEE value, as OEE depends on scheduled availability. A sub-optimal schedule would have lower scheduled availability but the equipment performance and quality would be the same, thus OEE calculations would be similar.

This emphasises the importance of generating an optimal schedule.

Our engineers have extensive experience in designing and delivering production scheduling systems.
