Executive Summary (Proposal Submission)
1. Objective & Decision Request
To address labor shortages and wage inflation while simultaneously expanding throughput capacity and controlling fixed costs (labor reduction), we propose deploying automated material handling equipment (AMR integration with WMS) at the distribution center.
- Total Investment (CAPEX): 42 Million JPY
- Payback Period: Approx. 3.9 Years (Well within the 5-year corporate hurdle rate)
- Operating Profit Contribution: +20 Million JPY (Cumulative over 5 years, post-depreciation)
- Approval Request: Authorization of 42 Million JPY CAPEX allocation and vendor contract execution.
2. Current Operational Bottlenecks & Strategic Necessity
- 1. Wage Inflation & Recruitment Bottlenecks: Despite wage increases, peak-period hiring remains difficult, causing overtime costs (~1.5M JPY/year) and delivery delay risks.
- 2. Manual Picking & Inspection Accuracy Limits: Manual workflows incur mis-shipment costs (~0.6M JPY/year in re-shipping and returns) and quality variance.
3. Investment Breakdown & Financial Forecast
① Capital Expenditure Breakdown (CAPEX: 42 Million JPY)
- Core Robotics & Racking (AMR Hardware): 30 Million JPY
- WMS / WCS Integration & Software Interface: 8 Million JPY
- Electrical, Network, and Infrastructure Work: 3 Million JPY
- Implementation Consulting & Project Management: 1 Million JPY
② 5-Year Income & Cash Flow Forecast (Overview)
- Annual Operating Expense (OPEX): 3.4 Million JPY / Year (Maintenance, software licenses, power)
- Annual Gross Savings: 15.0 Million JPY / Year (3 FTE labor reduction 12M JPY + 3M JPY overtime, error, and storage savings)
* Year 1 assumes an 80% realization rate (12M JPY) during operational ramp-up.
【5-Year Financial Summary】(Unit: Ten Thousand JPY)
• Net Annual Cash Flow: Year 1 +8.6M / Years 2–5 +11.6M annually
• Cumulative Cash Flow: Payback achieved in Year 4 (+1.4M) → Year 5 Cumulative +13.0M
• Operating Income Impact (Post-Depreciation): Year 1 +1.6M / Years 2–5 +4.6M annually (5-Yr Total +20.0M)

💡 Long-Term Upside (Year 6 Onward)
After full depreciation in Year 6 (7M JPY/year depreciation ends), the system generates +11.6 Million JPY per year in pure net cash flow.
5. Key Risk Mitigation Strategies
1. Initial Go-Live Disruption Risk
Mitigation: Execute a 1-month parallel test run alongside existing lines and model Year 1 savings conservatively at 80% capacity.
2. System Downtime & Hardware Failure Risk
Mitigation: Execute 24/7 on-site maintenance contracts (included in OPEX) and establish manual backup Standard Operating Procedures (SOPs).
6. Implementation Schedule
- Month 1 (Post-Approval): PO execution and system requirement definition
- Month 4: On-site installation and network deployment
- Month 5: Integration testing and operator training
- Month 6: Full go-live (followed by a 1 to 2-month ramp-up phase)
Anticipated Board & CFO Q&A Guide
Five critical questions anticipated from Board Members and CFOs regarding this 42M JPY automation proposal (~3.9-year payback), along with strategic response logics:
Q1. "You claim a 3-FTE labor reduction, but can we actually achieve headcount reduction or reassignments?"
【CFO Intent】 The CFO wants to ensure calculated savings translate into real cost reduction rather than leaving uncaptured fixed labor costs.
Recommended Response: "This project does not require layoffs. The center currently experiences natural monthly turnover filled via agency staff. Upon system go-live, we will freeze 3 replacement requisitions, directly reducing cash payroll. Experienced staff freed up by automation will be reassigned to peak-period exception handling, directly cutting overtime expenses (avg. 15 hrs/person/month)."
Q2. "You model Year 1 realization at 80%. What happens under a worst-case scenario (e.g., 50% realization due to delays)?"
【CFO Intent】 Risk officers want sensitivity analysis demonstrating cash flow safety under operational disruption.
Recommended Response: "Even if Year 1 realization falls to 50% (7.5M JPY annual savings), Year 1 operating cash flow remains positive (+4.1M JPY). Payback extends to ~4.4 years, still beating our 5-year hurdle rate. Furthermore, our vendor contract includes 1 month of parallel testing and on-site support to prevent go-live delays."
Q3. "Why invest now? Should we wait for robotics prices to fall or technology to mature?"
【CFO Intent】 Testing investment timing against opportunity costs and technology obsolescence.
Recommended Response: "Delaying investment incurs severe opportunity costs: wasted labor and overtime expenses (~11M JPY/year) exceed any future hardware price declines. Additionally, our architecture utilizes standardized WMS APIs, allowing modular fleet expansion or upgrades without discarding base infrastructure."
Q4. "Statutory life is 6 years. Will unexpected major repair costs occur in Years 5–6 (e.g., batteries or motors)?"
【CFO Intent】 Checking for hidden CAPEX or unmodeled OPEX spikes.
Recommended Response: "Our 3.4M JPY annual OPEX includes an all-inclusive maintenance SLA covering regular inspections and wearable parts (tires, belts). Battery replacements (~hundreds of thousands JPY) are fully budgeted within our annual 340k JPY consumables reserve, eliminating surprise capital demands."
Q5. "Compared to peer failure cases, why is this specific system selected?"
【CFO Intent】 Ensuring management is not buying over-engineered, rigid machinery pushed by vendors.
Recommended Response: "Peer failures typically stem from rigid, fixed AS/RS systems that cannot adapt to volume swings. We selected a flexible AMR architecture requiring zero fixed floor modifications, allowing fleet scaling on demand. Furthermore, single-unit robot failures do not stop the line, ensuring operational resilience."
Comparative Analysis: AMRs vs. Automated Warehouses (AS/RS)
Autonomous Mobile Robots (AMRs) and Automated Storage and Retrieval Systems (AS/RS) represent two distinct automation paradigms:
1. Core Feature Comparison
| Factor |
AMRs (Autonomous Mobile Robots) |
Automated Storage (AS/RS) |
| Primary Objective |

Maximize vertical clear height, full retrieval automation |
| CAPEX Requirement |
Low to Moderate (Tens of millions JPY) |
High (Hundreds of millions to billions JPY) |
| Lead Time |
Short (2–6 months) |
Long (1–2 years construction) |
| Flexibility & Scalability |
Extremely High (Easy fleet adjustments/relocation) |
Low (Fixed infrastructure hard to alter) |
| Storage Density |
Standard (Uses existing racking layouts) |
Extremely High (Utilizes full vertical volume) |
| Payback Period |
3 – 5 Years |
7 – 10+ Years |
2. ROI Profile Comparison
AMR (Mobile Robotics) ROI Profile
- Modular Implementation: Start with small fleets and scale as volume grows.
- Rapid Payback (3–5 Years): Eliminates heavy civil/structural modifications, driving fast returns primarily via travel labor reduction.
- Low Residual Risk: Fleet units can be easily relocated if hub leases expire or networks restructure.
AS/RS (Automated High-Bay Storage) ROI Profile
- Long Horizon Return (7–10 Years): High CAPEX requires multi-year strategic horizon planning.
- Significant Real Estate Savings: ROI is heavily driven by building footprint reduction (up to 50% space savings lowering facility lease costs).
- Fixed Cost Risk: Fixed depreciation and maintenance costs persist during off-peak volume drops.
3. Application Guidelines
【Select AMRs When:】
• Seeking labor reduction without altering existing facility layouts
• Handling volatile SKU counts or seasonal demand swings
• Operating in leased facilities where fixed structural modifications are prohibited
• Excessive operator travel time is the primary picking bottleneck
【Select AS/RS When:】
• Operating in owned (or long-lease) facilities with high clear ceiling heights (8–12m+)
• Handling standardized unit loads (pallets/totes) requiring high storage density
• Forecasting stable, long-term shipping volumes (10+ year horizon)
• Operating in high land-cost urban infill zones where footprints must be minimized
System Selection Checklist
Key checklist items to evaluate whether AMRs or AS/RS best suit facility requirements:
1. Facility Specifications
- Lease Term: Leased Facility / Owned Asset
- Dimensions: Total Floor Area & Clear Height (e.g., 5.5m vs. 10m+)
2. Product Characteristics
- Unit Load: Small cartons/pieces vs. Heavy bulk/pallets
- SKU Profile: High-SKU e-commerce vs. Low-SKU B2B bulk
3. Primary Operational Goals
- Examples: "Reduce picker travel labor" vs. "Eliminate external storage leases by maximizing vertical density"
