RTD (Real-Time Dispatching)

A solution that maximizes dispatching efficiency by selecting the optimal target in real-time for both equipment and lots.

Solution

RTD (Real-Time Dispatching)

Key Features

Determines lot and equipment priorities and issues transport instructions by configuring dispatching rules and linking with the Material Control System (MCS).
Dispatching Rule

  • What-Next rule (lot selection rule)

  • Where-Next rule (equipment selection rule)

  • Rule simulation function

Defect Analysis / Rule Improvement Management

  • Create priority rules based on various conditions - Same product/spec/production order priority rule - Priority-based rule - Reserved product priority rule - Queue time-based priority rule - Due date-based priority rule - Equipment with max idle port priority rule

Quality Certification / Document Management

  • View rule information applied to each process and equipment

  • Rule copy & phase function

  • Change history management of rules by process/equipment

  • Report on dispatched lots by process and equipment

Solution Advantages

Supports the establishment of full automation to enable efficient run execution.
Full Auto System Implementation

  • Eliminates operator’s discretionary decisions during run execution

  • Consistent run execution based on objective judgment criteria

  • Overcomes limitations of local optimization

Productivity Improvement

  • Enhances per-operator productivity by minimizing manual tasks on the shop floor

  • Improves overall process and equipment efficiency through full automation

  • Prevents operator errors with auto loading and unloading

Enhanced Customer Support

  • Improves quality by eliminating variability through systemization

  • Provides real-time tracking of product location via automated storage and movement

  • Reduces manufacturing turnaround time (TAT) through on-time delivery

Expected Benefits

Improved Equipment Utilization and Operating Rate

  • Minimizes downtime by assigning tasks based on current equipment status and priority

  • Balances workload by comparing planned vs. actual performance in real-time

Reduced Production Lead-Time

  • Reduces waiting time by allocating tasks based on real-time analysis of available resources (equipment, manpower, etc.)

  • Minimizes the gap between production plan and shop floor execution to achieve faster delivery

Minimized Work In Progress (WIP)

  • Issues work orders only as needed to reduce WIP and enhance process efficiency

  • Promotes smooth flow production through just-in-time and right amount input
