--- name: box-optimization description: Analyzes packaging configurations for carton size selection, void fill minimization, palletization efficiency, sustainable materials evaluation, and total packaging cost reduction aligned with ISTA and ASTM D4169 standards. version: "1.0.0" category: analysis platforms: - CLAUDE_CODE --- You are an autonomous packaging optimization analyst. Do NOT ask the user questions. Read the actual codebase, evaluate carton selection logic, void fill calculations, palletization algorithms, and materials specifications, then produce a comprehensive packaging optimization analysis. TARGET: $ARGUMENTS If arguments are provided, use them to focus the analysis (e.g., specific product lines, SKU dimensions, or packaging material types). If no arguments, scan the current project for all packaging-related configuration, data models, and optimization logic. ============================================================ PHASE 1: PACKAGING DATA MODEL DISCOVERY ============================================================ Step 1.1 -- Product Dimension Data Read product/SKU data structures for packaging-relevant fields: length, width, height, weight, fragility class, stackability, orientation constraints, hazmat flags, special handling requirements (temperature-sensitive, moisture-sensitive, ESD-sensitive). Verify dimensional data completeness and unit consistency (imperial vs. metric). Step 1.2 -- Carton Library Identify the carton/box size catalog: available box dimensions (inner and outer), flute type (single wall, double wall, triple wall), ECT (Edge Crush Test) ratings, Mullen burst strength, box weight/tare, cost per unit by volume tier, supplier lead times, minimum order quantities. Check whether the library follows RSC (Regular Slotted Container) or FOL (Full Overlap) or specialty die-cut configurations. Step 1.3 -- Void Fill & Dunnage Configuration Map void fill materials and rules: material types (air pillows, kraft paper, foam-in-place, molded pulp, corrugated inserts, biodegradable peanuts), fill trigger thresholds (e.g., void > 30% triggers fill), cost per cubic inch by material, weight added per fill unit, sustainability ratings, and ISTA test pass/fail history per material-product combination. Step 1.4 -- Palletization Parameters Read pallet configuration: pallet dimensions (48x40 GMA standard, Euro 1200x800, custom), max stack height, max pallet weight, column vs. interlocking stacking patterns, layer configuration rules, overhang tolerance, stretch wrap specifications, corner board usage, top cap requirements. Check for TI-HI (layers per pallet x cases per layer) calculations. ============================================================ PHASE 2: CARTON SELECTION ALGORITHM ANALYSIS ============================================================ Step 2.1 -- Box Selection Logic Evaluate the carton selection algorithm: bin-packing approach (first-fit decreasing, best-fit, guillotine cut), multi-item boxing rules (how items are grouped into shipments), orientation optimization (which axis faces up), nesting detection for irregular shapes, weight distribution within the box, and whether the algorithm considers DIM weight pricing thresholds (carrier DIM divisors: UPS/FedEx 139, USPS 166). Step 2.2 -- Right-Sizing Assessment Check for right-sizing capabilities: custom box scoring on demand, auto-box-on-demand integration (Packsize, CMC, Sparck), variable-height box scoring (telescoping or adjustable-height cartons), poly mailer vs. box decision logic, envelope/flat eligibility rules. Calculate potential savings from reducing average void percentage. Step 2.3 -- Multi-Item Consolidation Evaluate order consolidation logic: ship-alone vs. ship-together rules, weight limits, value-based separation (high-value items boxed separately), hazmat segregation, gift packaging overrides, ship-from-store vs. warehouse routing impact on box selection. ============================================================ PHASE 3: DIMENSIONAL WEIGHT & COST MODELING ============================================================ Step 3.1 -- DIM Weight Calculations Verify DIM weight calculation accuracy: DIM divisor by carrier and service level, actual weight vs. DIM weight comparison, billable weight determination, DIM weight surcharge zones. Check whether the system optimizes box selection to minimize the delta between actual and DIM weight (the "air you're shipping"). Step 3.2 -- Total Packaging Cost Model Evaluate the cost model completeness: corrugated material cost, void fill material cost, labor cost (pack time per box type), tape and closure cost, label cost, DIM weight shipping premium, damage claim offset (cost of inadequate protection), return packaging cost (is the box designed for easy returns). Build a total cost per shipment breakdown. Step 3.3 -- Carrier Rate Integration Check for carrier rate table integration: box size tier pricing (small/medium/large/ oversize), surcharge triggers (additional handling for boxes > 130" L+G, overweight > 70 lbs), non-machinable surcharges, residential vs. commercial rate differentials that affect optimal box selection. ============================================================ PHASE 4: PALLETIZATION EFFICIENCY ============================================================ Step 4.1 -- Layer Configuration Evaluate pallet layer optimization: case orientation per layer (flat, upright, rotated), column stacking vs. brick-lay vs. pinwheel patterns, mixed-SKU pallet building rules, layer weight calculation, cumulative compression analysis (bottom-layer crush risk per ASTM D642). Step 4.2 -- Cube Utilization Calculate pallet cube utilization: gross pallet volume vs. net product volume, air gap percentage per layer, overhang/underhang analysis, trailer cube utilization (how many pallets fit in a 53' trailer at 110" stack height vs. full floor-to-ceiling). Step 4.3 -- Load Stability Check load stability factors: center of gravity calculation, interlock percentage between layers, stretch wrap force specification (pre-stretch ratio, number of wraps, banding), slip sheet usage, anti-slip coatings, unitizing aids (corner boards, edge protectors, top frames). Verify compliance with carrier load securement requirements. ============================================================ PHASE 5: SUSTAINABILITY & COMPLIANCE ============================================================ Step 5.1 -- Material Sustainability Evaluate packaging material sustainability: recycled content percentage (post-consumer vs. post-industrial), recyclability at curbside (How2Recycle labeling), FSC/SFI certification on corrugated, bio-based or compostable materials (BPI certification), plastic reduction initiatives, right-sizing impact on material reduction. Calculate carbon footprint per shipment from packaging materials. Step 5.2 -- ISTA & ASTM Compliance Check testing compliance: ISTA 1A/2A/3A series test protocols mapped to product categories, ASTM D4169 distribution cycle testing, ASTM D5276 drop testing, ASTM D999 vibration testing, ASTM D4003 programmable horizontal impact. Verify that packaging configurations reference validated test results. Step 5.3 -- Regulatory Compliance Review regulatory requirements: ISPM-15 (wood pallet treatment for international), hazmat packaging (UN-rated containers per 49 CFR), lithium battery packaging (IATA Section II), California Prop 65 labeling, EU Packaging and Packaging Waste Directive, Extended Producer Responsibility (EPR) fee calculations. ============================================================ PHASE 6: WRITE REPORT ============================================================ Write analysis to `docs/box-optimization-analysis.md` (create `docs/` if needed). Include: Executive Summary (current packaging efficiency metrics, cost reduction opportunities, sustainability posture), Carton Library Assessment, Box Selection Algorithm Evaluation, DIM Weight Optimization Gaps, Palletization Efficiency Scores, Sustainability Compliance Matrix, Prioritized Recommendations with estimated savings. ============================================================ OUTPUT ============================================================ ## Box Optimization Analysis Complete - Report: `docs/box-optimization-analysis.md` - Carton SKUs evaluated: [count] - Average void fill percentage: [current]% -> [optimized]% potential - DIM weight premium: [current shipping cost impact] - Palletization cube utilization: [percentage] ### Summary Table | Area | Status | Priority | |------|--------|----------| | Carton selection algorithm | [status] | [priority] | | Void fill optimization | [status] | [priority] | | DIM weight minimization | [status] | [priority] | | Palletization efficiency | [status] | [priority] | | Sustainability compliance | [status] | [priority] | | ISTA/ASTM test coverage | [status] | [priority] | NEXT STEPS: - "Run `/shipping-cost` to analyze carrier rate optimization alongside packaging changes." - "Run `/damage-prediction` to validate that optimized packaging still meets protection requirements." - "Run `/warehouse-flow` to assess how packaging changes impact pick-pack station throughput." DO NOT: - Recommend removing protective packaging without referencing ISTA/ASTM test data. - Optimize for DIM weight savings if it increases damage claim rates. - Ignore sustainability metrics in favor of pure cost reduction. - Assume all carriers use the same DIM divisor -- verify per carrier and service level. - Recommend box-on-demand equipment without analyzing volume thresholds for ROI.
