Control Layer for Partial Rescheduling

A manufacturing control layer that preserves already prepared instructions and reschedules only the affected area after disruptions.

Control Layer Frozen Instructions Postponed Instruction Urgent Order Insertion API Ready

The Problem

Traditional Scheduling

Delay / urgent order → broad rescheduling

  • Large recalculation scope
  • Already prepared shop-floor instructions may change
  • Materials, tools, and operator preparation can be disrupted
  • Manual coordination cost increases

Control Layer Approach

Delay / urgent order → Control Layer → partial rescheduling

  • Frozen instructions remain unchanged
  • Problematic instruction is postponed
  • Urgent order is inserted after the frozen range
  • Only the unfrozen area is rescheduled

Demo Scenario

Example Conditions

  • Industry: Semiconductor
  • Postponed instruction: Order003 - Wafer Lot C / Material Waiting
  • Reason: Material shortage
  • Frozen range: First 2 instructions remain unchanged
  • Urgent order: UrgentOrder-X inserted after frozen range

Before Schedule

Initial production order before applying the Control Layer.

Position Instruction Line / Resource Sequence Duration
1 Order001 - Wafer Lot A / Standard Process Line 1 1 2h
2 Order002 - Wafer Lot B / Standard Process Line 1 2 2h
3 Order003 - Wafer Lot C / Material Waiting Line 1 3 3h
4 Order004 - Wafer Lot D / Standard Process Line 1 4 2h
5 Order005 - Wafer Lot E / Urgent Customer Lot Line 1 5 3h

Position Instruction Status Reason
1 Order001 - Wafer Lot A / Standard Process Frozen Already prepared instruction remains unchanged
2 Order002 - Wafer Lot B / Standard Process Frozen Already prepared instruction remains unchanged
3 UrgentOrder-X / High Priority Urgent Inserted immediately after the frozen range
4 Order004 - Wafer Lot D / Standard Process Rescheduled Moved within the unfrozen area
5 Order005 - Wafer Lot E / Urgent Customer Lot Rescheduled Moved within the unfrozen area
6 Order003 - Wafer Lot C / Material Waiting Postponed Material shortage

What This Demonstrates

Operational Value

  • Prepared instructions are not disturbed
  • Urgent orders can be inserted without full replanning
  • Only the affected area is recalculated
  • Change boundaries are explainable to operators

Business Value

  • Reduces manual coordination after disruptions
  • Supports stable factory execution
  • Can be integrated with APS / MES systems
  • Designed as an API-ready control layer
