a5c-ai Production Scheduler
Overview
The Production Scheduler skill provides comprehensive capabilities for optimizing production schedules. It supports finite capacity scheduling, changeover optimization, due date prioritization, and real-time rescheduling to maximize throughput and on-time delivery.
Capabilities
- Finite capacity scheduling
- Changeover sequence optimization
- Due date prioritization
- Machine assignment optimization
- Setup time reduction
- Order splitting strategies
- Schedule compression techniques
- Real-time rescheduling

Scheduling Objectives
| Objective | Description | Metric |
|---|---|---|
| On-time delivery | Meet customer due dates | % on-time |
| Throughput | Maximize output | Units/day |
| Utilization | Efficient resource use | % utilized |
| Changeover | Minimize setup time | Total setup hours |
| WIP | Minimize work in process | $ WIP value |
Scheduling Rules
Priority Rules
- EDD (Earliest Due Date) - Schedule by due date
- SPT (Shortest Processing Time) - Shortest jobs first
- FCFS (First Come First Served) - Order received
- CR (Critical Ratio) - Time remaining / work remaining
Sequencing Rules
- Grouping - Similar products together
- Optimal changeover - Minimize total setup time
- Color wheel - Light to dark, small to large
Schedule Optimization
Minimize: Total Lateness + (Changeover Time x Weight)
Subject to:
- Capacity constraints
- Due date requirements
- Material availability
- Resource skills
Real-Time Rescheduling Triggers
- Machine breakdown
- Rush order arrival
- Material shortage
- Quality issue
- Labor absence
Integration Points
- ERP/MRP systems
- Manufacturing Execution Systems
- Order management systems
- Shop floor data collection
