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

Used By Processes

CAP-002: Production Scheduling Optimization
TOC-002: Drum-Buffer-Rope Scheduling
LEAN-004: Kanban System Design

Tools and Libraries

Scheduling algorithms
Optimization solvers (Gurobi, CPLEX, OR-Tools)
ERP scheduling modules
APS systems

Usage

skill: production-scheduler
inputs:
  orders:
    - order_id: "ORD001"
      product: "Widget A"
      quantity: 500
      due_date: "2026-02-10"
      priority: "high"
    - order_id: "ORD002"
      product: "Widget B"
      quantity: 300
      due_date: "2026-02-12"
      priority: "normal"
  resources:
    - machine: "Press 1"
      available_hours: 16
      products: ["Widget A", "Widget B", "Widget C"]
    - machine: "Press 2"
      available_hours: 16
      products: ["Widget A", "Widget C"]
  changeover_matrix:
    "Widget A -> Widget B": 30  # minutes
    "Widget A -> Widget C": 45
    "Widget B -> Widget A": 25

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
