Changeover Optimizer

Overview

The Changeover Optimizer skill provides comprehensive capabilities for reducing setup and changeover times. It supports SMED (Single-Minute Exchange of Die) methodology, sequence optimization, and changeover time tracking.

Capabilities

• Internal/external setup separation
• Changeover video analysis
• Parallel task identification
• Standardization opportunities
• Quick-release mechanisms
• Sequence optimization
• Changeover matrix
• Time reduction tracking

Used By Processes

• LEAN-004: Kanban System Design
• CAP-002: Production Scheduling Optimization
• LEAN-003: Kaizen Event Facilitation

Tools and Libraries

• Video analysis tools
• SMED templates
• Time study software
• Scheduling optimization

Usage

skill: changeover-optimizer
inputs:
  equipment: "Injection Molding Press 5"
  current_changeover_time: 120  # minutes

SMED Methodology

Stage 1: Separate Internal and External Setup

Stage 2: Convert Internal to External

• Pre-stage tools and materials
• Pre-heat/pre-cool components
• Prepare documentation
• Pre-adjust settings

Stage 3: Streamline All Operations

• Parallel tasks (multiple operators)
• Eliminate adjustments
• Standardize procedures
• Use quick-release mechanisms

Changeover Analysis

Current State:
- Total time: 120 minutes
- Internal: 100 minutes
- External: 20 minutes

Improvement Opportunities:
1. Move mold retrieval to external: -20 min
2. Pre-heat mold: -10 min
3. Use quick-clamps: -15 min
4. Parallel connection work: -10 min
5. Eliminate test shots: -15 min

Target State:
- Total time: 30 minutes
- Internal: 25 minutes
- External: 35 minutes
