Reclaiming the Long View: How Network Optimisation and Scenario Modelling Drive Strategic Investments in 2025

Introduction: A Shift in Perspective

2024 was a year of firefighting for many organisations, with leaders focused on managing immediate pressures such as supply chain disruptions, inflation, and geopolitical uncertainty. As the dust settles, 2025 is shaping up to be a year of recalibration. Companies are once again exploring medium to long-term investments to secure a competitive edge in an evolving landscape.

Network optimisation and scenario modelling are pivotal in this shift. These tools allow organisations to analyse, predict, and plan their supply chain strategies more effectively, unlocking cost savings and operational efficiencies across multiple areas.

This article delves into how network optimisation can drive tangible benefits across warehouse labour, freight, warehouse rents, and inventory, enabling organisations to achieve a balance between short-term agility and long-term sustainability.

Understanding Network Optimisation and Scenario Modelling

Network Optimisation involves evaluating an organisation's supply chain and logistics networks to determine the most efficient configuration. This might include decisions about warehouse locations, transport routes, and inventory placement, all aimed at minimising costs and maximising service levels.

Scenario Modelling complements optimisation by allowing businesses to simulate different conditions, such as changes in demand, costs, or constraints. This proactive approach helps leaders make informed decisions in an uncertain environment.

In 2025, organisations leveraging these tools gain the ability to:

• Reduce costs through efficiency improvements.
• Enhance customer satisfaction by improving service reliability.
• Build resilience by stress-testing networks against potential disruptions.

Key Areas of Cost Optimisation

1. Warehouse Labour Spend

Labour remains one of the most significant operating costs in supply chains. Network optimisation identifies opportunities to reduce labour spend by:

• Consolidating Warehouses: Reducing the number of facilities while maintaining service levels can eliminate redundant labour requirements.
• Improving Labour Utilisation: Optimising workflows and scheduling can ensure the workforce is deployed efficiently.
• Leveraging Automation: Network analysis can highlight where investments in automation, such as robotics or advanced WMS (Warehouse Management Systems), could deliver a strong ROI.

Example:
A major FMCG company used network optimisation to consolidate three regional warehouses into one strategically located distribution centre. This move reduced labour costs by 20%, as fewer workers were needed to manage inventory and fulfil orders.

2. Freight Spend

Freight is another high-impact area where optimisation delivers results. By evaluating transport routes, carrier options, and modal choices, organisations can:

• Minimise shipping costs through efficient routing.
• Improve load utilisation, reducing the number of trips required.
• Shift to cost-effective transport modes where feasible, such as rail or sea freight for long distances.

Scenario Modelling in Action:
Businesses can use scenario modelling to assess the impact of fuel price increases or changes in carrier rates, allowing them to secure better contracts or adjust pricing strategies.

Case Study:
A retailer in ANZ re-evaluated its distribution network, switching from road to rail for inter-state deliveries. This reduced freight costs by 15% and lowered carbon emissions, aligning with sustainability goals.

3. Warehouse Rents

In 2025, skyrocketing commercial property prices and rising rental rates are pressing issues for businesses. Network optimisation can help mitigate these costs by:

• Identifying underperforming warehouses that could be closed or relocated.
• Assessing lease agreements and exploring renegotiation or alternative options.
• Exploring shared warehousing models or co-location with partners to reduce fixed costs.

Data-Driven Lease Decisions:
Scenario modelling can simulate the long-term financial impact of staying in a high-rent facility versus moving to a more affordable location, considering factors like transport cost implications and service levels.

4. Inventory and Working Capital

Inventory optimisation is a cornerstone of working capital management. Excess stock ties up capital and increases carrying costs, while stockouts can damage customer relationships. Network optimisation addresses this by:

• Balancing inventory levels across the network to minimise overstocking and understocking.
• Positioning inventory closer to demand centres to reduce lead times and safety stock requirements.
• Improving demand forecasting to align inventory with actual market needs.

Advanced Tools:
AI-powered forecasting and optimisation tools can further enhance accuracy, helping businesses dynamically adjust inventory in response to changes in demand or supply.

Real-World Impact:
A healthcare company used network optimisation to centralise its inventory at a regional distribution hub. This reduced inventory holding costs by 25% while maintaining 98% service levels.

Why 2025 is the Year for Medium to Long-Term Investments

The Supply Chain Behind Building Homes in Australia: Challenges and Opportunities in Scaling Up for Housing Affordability

Australia is facing a housing crisis. Skyrocketing prices, tight rental markets, and a growing population have left many struggling to find affordable housing. In response, governments and industry leaders have called for a significant ramp-up in housing construction. However, achieving this goal is not as simple as just building more homes. The construction of houses depends on a complex supply chain, and any disruption in this ecosystem can slow progress, increase costs, and undermine affordability initiatives.

From raw materials and manufacturing to logistics and labour availability, the entire supply chain must gear up to meet demand. This article explores the supply chain behind home construction in Australia, the current bottlenecks, and what needs to change to support the ambitious push for increased housing supply.

1. The Housing Construction Supply Chain: A Complex Ecosystem

Building a home in Australia requires the seamless coordination of multiple supply chain components, from sourcing raw materials to final construction. The supply chain for housing consists of:

1.1 Raw Material Extraction & Processing

The foundation of home construction lies in key materials such as:

• Timber (for framing, flooring, and cladding)
• Concrete and cement (for foundations, slabs, and walls)
• Bricks and steel (for structural elements)
• Glass and plasterboard (for interiors)

These materials are sourced domestically and internationally, with significant reliance on imports for steel, engineered wood products, and fixtures. The demand surge for housing means these materials must be supplied in greater volumes and at a steady rate to avoid project delays.

1.2 Manufacturing & Fabrication

Once raw materials are processed, they move into manufacturing:

• Prefabricated wall frames and trusses
• Windows and doors
• Cabinetry, plumbing, and electrical components
• Fixtures like taps, sinks, and appliances

Australia’s manufacturing sector must be prepared for higher production volumes, requiring investment in machinery, automation, and workforce expansion.

1.3 Transport & Logistics

Getting materials from manufacturers to building sites is a critical but often overlooked aspect of the construction supply chain. The industry relies on:

• Domestic freight networks (road and rail)
• Ports for imported materials
• Warehousing and distribution hubs

Delays in transport—due to congestion, driver shortages, or fuel costs—can impact construction timelines and inflate costs.

1.4 Labour & Construction

Labour availability is one of the biggest constraints in homebuilding today. Skilled trades such as carpenters, bricklayers, electricians, and plumbers are already in short supply. With the push for more housing, Australia will need a significant increase in construction workers.

2. Current Bottlenecks in the Housing Construction Supply Chain

While there is growing demand for housing, various supply chain bottlenecks make it difficult to accelerate construction. These include:

2.1 Supply Chain Disruptions

The pandemic exposed vulnerabilities in global and domestic supply chains, with extended lead times and price volatility for key materials. The war in Ukraine and geopolitical tensions have further impacted global trade, leading to:

• Increased costs for steel, timber, and other critical materials
• Delays in the arrival of imported building products
• Shortages of essential components such as plumbing and electrical fittings

2.2 Labour Shortages

The construction industry has long struggled with workforce shortages, and this issue has only worsened. Factors contributing to the problem include:

• An ageing workforce and lack of new apprentices
• Border closures during COVID-19, limiting skilled migration
• Rising costs of living deterring people from trades
• Competition from infrastructure and mining projects

Without a concerted effort to attract and train workers, labour shortages will continue to delay housing projects.

2.3 Land Supply & Planning Delays

Even if materials and labour are available, planning processes can slow down housing developments. Local councils and state governments control zoning, approvals, and infrastructure provisioning, which can create bottlenecks. Key issues include:

• Lengthy approval times for new housing developments
• Infrastructure constraints (roads, utilities, public transport)
• Restrictive zoning laws limiting density in urban areas

2.4 Cost Inflation

Rising costs in construction make affordability a moving target. Builders are facing:

• Higher material costs due to supply chain disruptions
• Increased wages due to labour shortages
• Inflationary pressures on fuel and logistics
• Increased financing costs due to rising interest rates

Without intervention, these cost pressures will continue to push home prices higher.

3. Scaling Up the Supply Chain to Support Housing Growth

If Australia is serious about increasing housing supply, the supply chain needs to scale up in multiple ways:

3.1 Expanding Local Manufacturing & Material Supply

Reducing reliance on imports by investing in local manufacturing can provide stability in material supply. Initiatives should include:

• Expanding timber plantations and sawmills
• Increasing steel and concrete production capacity
• Supporting prefabrication and modular housing manufacturing
• Encouraging investment in circular economy construction materials

3.2 Strengthening Logistics & Freight Networks

Supply chain resilience depends on efficient logistics. Improvements could include:

• Investment in better road and rail freight infrastructure
• Digitisation of supply chain tracking for real-time visibility
• Reducing red tape in cross-border transport of building materials
• Incentives for sustainable freight options

3.3 Addressing Workforce Shortages

To meet demand, Australia must boost its construction workforce by:

• Expanding apprenticeship programs and funding trade education
• Accelerating skilled migration for construction trades
• Increasing wages and conditions to attract workers to the industry
• Encouraging more women and underrepresented groups into construction

3.4 Reforming Planning & Development Processes

Regulatory reforms can accelerate housing supply by:

• Fast-tracking approvals for well-located housing projects
• Encouraging medium-density housing in suburban areas
• Investing in infrastructure to unlock new housing supply
• Providing incentives for build-to-rent developments

3.5 Embracing Innovation & Technology

Technology can play a role in scaling up housing supply. Innovations include:

• Prefabricated and modular housing to speed up construction
• Building Information Modelling (BIM) for more efficient planning
• Automated construction techniques to reduce reliance on manual labour
• Sustainable materials and energy-efficient design to lower long-term costs

4. The Role of Government & Industry Collaboration

Scaling up the housing supply chain requires collaboration between government and industry. Key strategies include:

• Public-private partnerships to invest in supply chain capacity
• Incentives for local manufacturing and prefabrication
• Fast-tracking visa processing for skilled trades
• Regulatory reforms to streamline development approvals
• Subsidies or tax incentives for affordable housing projects

Government-led programs such as the National Housing Accord and state-based housing funds will be crucial in aligning the interests of builders, suppliers, and policymakers.

Building the Future of Housing in Australia

The push for more housing in Australia is not just about construction—it’s about strengthening the entire supply chain that supports it. Without addressing supply chain constraints, workforce shortages, and regulatory bottlenecks, efforts to improve housing affordability will face significant roadblocks.

By expanding local material production, improving logistics, attracting more workers, and reforming planning systems, Australia can create a more efficient, resilient, and scalable housing supply chain.

The question remains: Will the industry and government work together fast enough to meet the challenge?

The Critical Role of Back-of-House (BOH) Operations in Hospital Master Planning

Why BOH Operations Matter in Hospital Development

Hospital master planning is a complex undertaking that shapes the functionality, safety, and efficiency of a healthcare facility for decades to come. While much attention is given to clinical spaces, patient experience, and aesthetics, one critical yet often overlooked aspect is back-of-house (BOH) operations.

BOH areas—loading docks, supply chain logistics, waste management, food service, linen handling, and sterile processing—are the lifeblood of hospital operations. Poor planning can lead to safety risks, inefficiencies, traffic congestion, compliance failures, and escalating costs to serve.

This is particularly critical in the Asia-Pacific (APAC) region, where rapid urbanisation, population growth, and ageing demographics are driving demand for efficient, scalable, and cost-effective healthcare facilities.

This article explores why BOH operations must be prioritised in hospital master planning to mitigate risks and optimise performance.

1. BOH Infrastructure & Traffic Management: Mitigating Safety & Congestion Risks

The Challenge: Overcrowded Loading Docks & BOH Corridors

Many hospitals in densely populated APAC cities face severe congestion in their BOH areas due to:
❌ High delivery volumes from multiple suppliers
❌ Poorly designed loading docks that create bottlenecks
❌ Limited space for goods movement
❌ Inadequate separation of hospital staff, suppliers, and patients

Without careful planning, these issues lead to:
⚠ Traffic congestion → Delayed deliveries & increased logistics costs
⚠ Worker & patient safety hazards → Risk of accidents in loading dock areas
⚠ Service inefficiencies → Staff spending more time managing deliveries instead of patient care

The Solution: Smart BOH Design & Traffic Flow Optimisation

Hospitals can proactively mitigate these risks through:

✔ Optimised loading dock layouts → Dedicated zones for deliveries, waste removal & linen services
✔ Vehicle scheduling & dock appointment systems → Reduces congestion & waiting times
✔ Separation of BOH & patient flow → Avoids cross-contamination & ensures HACCP compliance
✔ Use of Automated Guided Vehicles (AGVs) → Minimises manual handling & enhances safety

Strategic BOH master planning ensures that logistics and clinical operations are seamlessly integrated, reducing traffic risks, service disruptions, and operational costs.

2. Cost-to-Serve & Operational Efficiency: The Hidden ROI of BOH Planning

The Challenge: Uncontrolled Operating Costs Due to Poor BOH Design

If BOH operations are not considered early, hospitals face higher long-term costs from:
❌ Inefficient workflows → Increased manual labour & staff fatigue
❌ Excessive stockholding & poor inventory management → Inflated working capital costs
❌ Poor layout of central stores → Inefficient picking & replenishment
❌ High transport & distribution costs → Due to suboptimal supply chain networks

The Solution: Integrated BOH & Supply Chain Design

✔ Automated storage & retrieval systems (ASRS) → Improves accuracy & labour efficiency
✔ Demand forecasting & AI-driven inventory models → Reduces carrying costs while ensuring supply availability

When hospitals design BOH operations with a supply chain mindset, they unlock significant savings in labour, inventory, logistics, and utilities, making long-term operations more financially sustainable.

3. Food & Linen Services: HACCP & Compliance Considerations

The Challenge: Food Safety & Linen Handling Risks in Hospital BOH Areas

Hospital food & linen services present serious risks if BOH workflows are not carefully managed:
⚠ Cross-contamination risks → Poor segregation of clean & dirty zones
⚠ HACCP non-compliance → Leading to regulatory penalties & foodborne illness risks
⚠ Delivery bottlenecks → Late meal & linen replenishments impacting patient care

The Solution: BOH Design for Safe & Compliant Service Delivery

Hospitals must adopt purpose-built BOH spaces with:

✔ Separate entry & exit zones for food, linen, and waste flows
✔ Temperature-controlled food storage & distribution areas
✔ Barrier workflows & segregated waste handling for infection control
✔ Digital traceability & HACCP-compliant food monitoring systems

By designing BOH with compliance at the core, hospitals avoid safety risks, regulatory issues, and costly operational inefficiencies.

4. Waste Management & Sustainability: Future-Proofing BOH for Green Hospitals

The Challenge: Rising Waste Volumes & Sustainability Pressures

Hospitals generate enormous waste streams, including:
🗑 Clinical & biohazard waste → Requires strict disposal protocols
♻ Recyclable & general waste → Growing regulatory pressure for sustainability
🍽 Food & organic waste → Needs proper composting & disposal

Poor BOH waste handling leads to:
❌ Environmental & regulatory compliance risks
❌ Odour, hygiene & pest control challenges
❌ High disposal costs & inefficiencies

The Solution: Sustainable BOH Waste Management

✔ Automated waste chutes & pneumatic waste disposal → Reduces contamination risks
✔ Recycling & circular waste economy → Reduces landfill impact
✔ On-site food waste digesters & composting → Sustainable F&B operations
✔ Green building certifications → Aligns with APAC healthcare sustainability goals

Hospitals that integrate sustainable BOH waste systems achieve lower costs, better hygiene, and regulatory compliance while improving their environmental footprint.

BOH Master Planning—A Critical Success Factor for APAC Hospital Developments

As APAC’s healthcare infrastructure expands, hospital developments must prioritise BOH operations in the Master Planning phase to:

✅ Avoid congestion, traffic & safety risks → Through smart loading dock & logistics design
✅ Optimise cost-to-serve & service efficiency → By integrating BOH & supply chain strategies
✅ Ensure HACCP compliance & safe food/linen services → Through workflow segregation & monitoring
✅ Implement sustainable waste management → To align with green hospital standards

Neglecting BOH operations in master planning creates long-term operational challenges that are costly, inefficient, and difficult to fix post-construction.

Is your hospital project designing for BOH success? By engaging supply chain and healthcare logistics specialists early, APAC hospital developments can achieve safer, more efficient, and future-proof healthcare infrastructure.
