Delivering what business demands

According to the weekly plan generated by the planning module, the production order is created to be scheduled. The schedule includes all current and backlog production orders. Based on the production schedule, charging schedule gets generated which tells about inventory position and their availability at EAF, skid and further processing unit. Yard operators are provided with visibility to keep material according to the feed requirement.

Scheduling considers the campaign requirements of all the processes to deliver the best sequence of heats. Scheduling works on Theory of Constraints (TOC) to identify the critical operation and accordingly builds the campaigns on all the operations. Building campaigns as per caster heat sequence results into sub-optimal utilization of the overall capacity.

Scheduling optimizes based on various constraints & objectives. Some key system objectives are defined below:

  • Cost minimization
  • Throughput maximization
  • On-time delivery
  • Mill utilization maximization

Some of the scheduling rules and constraints are listed below:

  • Processing Speed
  • Capacity Limitations
  • Equipment Life [rolls.. etc.]
  • Start up constraints and end constraints
  • Grades compatibility.
