Key Optimization Considerations in Cutting Stock Problems

CutsBest is designed to handle a wide range of real-world complexities in optimizing material usage. Below are some of the key factors that CutsBest considers:

1. Cost Optimization

• Minimizing Raw Material Costs – The primary goal is to reduce the total cost of raw materials by optimizing cutting patterns.
• Machine Usage Costs – CutsBest considers operational costs and encourages solutions that efficiently use wide raw material widths.
• Setup & Order Splitting Costs – Reducing the cost of switching between patterns and minimizing consolidation efforts for shipments.

2. Material Constraints & Availability

• Limited Raw Material Supply – The software accounts for finite inventory levels and prevents cutting beyond available stock.
• Minimum Order Quantities – If raw materials must be ordered in bulk, CutsBest ensures compliance with supplier minimums.
• Bundles of Raw Material – Some materials, such as steel rods, are shipped in fixed bundle sizes, requiring cuts to align with bundle quantities.

3. Cutting & Waste Management

• Kerf (Cut Waste) – When using saws instead of shears, the system factors in material lost during cutting.
• Edge Waste vs. Overage Waste – CutsBest balances leftover raw material against excess finished goods to optimize future usage.
• Minimum & Maximum Edge Waste – Some industries need to restrict edge waste for handling and disposal efficiency.

4. Production Flexibility

• Material-Specific Products – Ensures that different materials (e.g., varying thickness or surface finish) are not mixed in the same cutting pattern.
• Upgrading Costs – When beneficial, CutsBest allows for using higher-grade material to reduce waste or improve efficiency.
• Stock Width Change Costs – Pattern changes that require switching raw material widths take longer, so the system favors solutions minimizing these changes.

5. Production Scheduling & Logistics

• Due Dates & Sequencing – Prioritizes urgent orders and sequences production for faster fulfillment.
• Inventory Restrictions – Aims to consolidate customer orders into fewer cutting patterns to minimize work-in-process inventory.
• Limit on Pattern Changes – In industries like paper manufacturing, frequent pattern changes slow production; CutsBest optimizes batch processing.
• Pattern Restrictions – Limits the number of widths per pattern to meet industry constraints (e.g., take-up reels in paper mills).
• Pattern Pairing – In certain manufacturing setups, two cuts must be made simultaneously (e.g., plastic wrap or paper production with defects).

6. Advanced Optimization Considerations

• Raw Material Library Selection – Helps manufacturers decide the best standard raw material lengths to stock based on demand forecasts.
• Order Splitting Costs – Balances the cost of producing a demand width across multiple patterns against consolidation costs.
• Two-Dimensional Cutting – Supports cutting layouts for sheet-based materials like plywood, fabric, or corrugated paper.
