How to Improve ASRS Throughput in Dutch Warehouses

Greenfield warehouse projects start with a blank canvas. You design the building around optimal automation specifications, specify exact floor tolerances, and configure racking from day one for automated operation.

Dutch retrofits work differently. You inherit existing manual pallet racking, floor surfaces that may not meet traditional ASRS flatness requirements, and buildings designed decades ago for forklift operations. Ceiling heights often restrict vertical storage options that newer facilities take for granted.

Floor flatness presents one of the most significant retrofit challenges. Traditional ASRS systems require super-flat floors with tolerances measured in millimetres. Older Dutch warehouses rarely meet these specifications, forcing expensive floor remediation or limiting automation options.

Column placement creates another obstacle. Buildings designed for manual operations position structural supports based on construction efficiency, not optimal automation flow. These columns interrupt ideal racking configurations and create traffic routing complications.

Electrical infrastructure also requires assessment. Older facilities may lack the power capacity or distribution points needed for shuttle charging stations, VTUs, and conveyor systems operating at full throughput.

Free-roaming shuttle technology offers a more flexible approach to retrofit automation. Rather than relying on a rigid, one-size-fits-all ASRS layout, Moffett Automation designs shuttle-based storage systems around the constraints of the existing facility, including building dimensions, column positions, pallet profiles, operational flows and available floor space.

The shuttle operates freely within the engineered storage structure, allowing high-density automated storage to be adapted to real-world retrofit conditions while reducing the need for unnecessary building disruption and supporting strong throughput performance.

Accurate throughput assessment prevents costly mistakes during retrofit planning. You need baseline data on current operations, realistic projections for automated performance, and clear understanding of where bottlenecks will shift as you introduce automation.

Start by documenting how pallets move through your facility today. Track inbound receiving patterns, storage location assignments, retrieval sequences, and outbound staging workflows. This mapping reveals inefficiencies that automation can address and highlights areas where manual processes will continue.

Peak period analysis matters more than average throughput figures. Your system must handle the busiest hours, not just typical operations. Document seasonal variations, promotional periods, and any patterns that create demand spikes.

Bottlenecks in manual pallet racking systems typically cluster around a few key points. Aisle congestion occurs when forklifts compete for access to popular storage locations. Receiving docks back up when inbound volume exceeds put-away capacity. Picking areas slow down when order profiles change faster than layout adjustments can accommodate.

These same bottleneck locations often shift rather than disappear when you introduce automation. Understanding current constraints helps you design systems that eliminate root causes rather than simply moving problems to new locations.

Many vendor specifications describe ideal conditions. Your retrofit will not achieve ideal conditions. Calculate realistic targets by accounting for mixed operations during phased implementation, integration points between automated and manual zones, and maintenance windows that reduce available operating hours.

Build your projections conservatively. A system that consistently exceeds expectations creates operational confidence. One that falls short generates frustration and undermines support for further automation investment.

Layout modifications during retrofits require balancing throughput optimisation against practical constraints. You cannot move structural columns or dramatically expand floor space. However, strategic changes to storage configuration and intelligent use of zoning and buffering can substantially improve automated throughput within existing footprints.

Manual pallet racking aisles were designed for forklift operation. These aisles often exceed the width shuttles require, wasting valuable floor space. Narrower aisles dedicated to automated traffic increase storage density while maintaining or improving throughput.

Consider aisle direction relative to inbound and outbound points. Shuttles moving pallets from receiving to storage and from storage to shipping should travel the shortest practical distances. Layout changes that reduce average travel distance directly improve throughput capacity.

Every retrofit includes interfaces between automated and manual operations. These buffer zones handle transitions, pallets arriving from trucks before entering automated storage, or retrieved pallets staging for manual order assembly. Insufficient buffer capacity creates bottlenecks that ripple through the entire system.

Design buffer zones based on peak flow rates, not averages. Include enough capacity to absorb temporary imbalances in operations. This buffering prevents temporary slowdowns in one area from halting production throughout the facility.

Moffett Automation VTU placement is determined by the overall system flow rather than by layout convenience alone. Each VTU is positioned to support the required pallet movements between storage levels, inbound and outbound interfaces, conveyor connections, shuttle routes and operational demand patterns.

Where throughput requirements justify it, multiple VTUs can be used to increase vertical movement capacity, reduce waiting time and add resilience. However, VTU performance depends on the full system design, including shuttle allocation, buffer strategy, software sequencing and integration with upstream and downstream equipment.

Hardware alone cannot maximise ASRS throughput. Warehouse Control System (WCS) software orchestrates shuttle movements, manages traffic flow, and coordinates operations across all system components. Optimised WCS configuration often delivers throughput improvements exceeding what hardware upgrades alone can achieve.

Multiple shuttles operating in shared spaces create traffic management challenges. Without intelligent coordination, shuttles wait for each other, take inefficient routes, and create congestion at popular storage locations.

Moffett Automation WCS software implements real-time traffic management that anticipates conflicts before they occur. The system calculates optimal routes considering current shuttle positions, pending tasks, and predicted movements. This predictive approach keeps shuttles moving continuously rather than waiting for reactive path clearing.

Static storage location assignments waste throughput capacity. Popular items stored far from outbound points require longer retrieval times. Seasonal products remain in premium locations after demand declines.

Dynamic storage allocation continuously adjusts inventory positioning based on actual demand patterns. The WCS monitors retrieval frequency and automatically relocates inventory to optimise overall throughput. High-velocity items migrate toward outbound points while slower-moving stock shifts to less accessible locations.

Inbound and outbound operations compete for system capacity. Uncoordinated scheduling creates periods of intense activity followed by idle time. This uneven demand reduces effective throughput and increases peak capacity requirements.

Advanced WCS scheduling balances inbound receiving with outbound shipping demands. The system sequences tasks to maintain steady throughput rather than handling operations on a first-come basis. This coordination smooths demand peaks and extracts maximum throughput from available capacity.

Throughput optimisation extends beyond speed. Energy consumption per pallet handled affects operating costs, especially in cold storage environments where every unnecessary shuttle movement adds heat load to refrigeration systems.

Intelligent traffic routing minimises total shuttle travel distance while maintaining throughput targets. The WCS consolidates movements when possible, selects energy-efficient routes, and coordinates charging schedules to keep shuttles available during peak demand periods. Moffett Automation’s Eco Traffic Intelligence delivers both throughput and sustainability benefits.

Your warehouse management system tracks inventory, processes orders, and directs operational activities. The WCS must exchange information with your WMS to coordinate automated and manual operations.

Moffett Automation systems integrate with existing warehouse management and ERP platforms through standard interfaces. This integration ensures inventory accuracy, order processing efficiency, and operational visibility across both automated and manual warehouse zones.

Complete warehouse automation rarely happens overnight. Phased implementation maintains operations during the transition while progressively expanding automated coverage. Successful phasing requires careful sequencing, clear handoff points between project stages, and realistic timelines for each phase.

Start automation where it delivers the greatest immediate benefit. High-turnover storage zones, temperature-sensitive areas requiring reduced human exposure, and locations with persistent labour challenges typically offer the best initial returns.

Initial phase success builds organisational support for continued investment. Select areas where automation advantages will be immediately visible and measurable. Early wins create momentum for subsequent phases.

Your warehouse cannot stop shipping orders during retrofit construction. Phased implementation must maintain adequate manual capacity throughout the transition. This often means accepting temporary inefficiencies as you operate hybrid automated and manual systems simultaneously.

Plan manual capacity requirements for each phase carefully. Identify which staff, equipment, and processes will continue operating and for how long. Communicate transition timelines clearly so operations teams can prepare for changing workflows.

Adding capacity to operating automated systems requires coordination. New shuttles must integrate with existing traffic management. Additional storage levels need VTU capacity to handle increased vertical movement. Expanded zones must interface cleanly with already-automated areas.

Moffett Automation designs systems with scalability built in from initial installation. Modular hardware configurations and software architectures accommodate expansion without requiring fundamental redesign. This scalability planning reduces disruption and accelerates completion of subsequent phases.

Transfer points – locations where pallets move between different handling systems – frequently become throughput constraints. Automated systems may operate well independently while their connection points limit overall performance. Addressing these bottlenecks requires both hardware solutions and operational process changes.

Pallets arriving by truck must transition from manual unloading to automated storage. This receiving integration often limits how quickly inbound volume enters the system. Dock door availability, pallet inspection requirements, and label scanning all affect receiving throughput.

In-rack conveyor systems can accelerate receiving by moving pallets from dock areas directly into automated storage zones. This integration eliminates forklift transport between receiving and storage, reducing labour requirements while increasing throughput.

Retrieved pallets moving toward shipping face similar transition challenges. Outbound staging areas must accumulate complete orders before loading, handle mixed-temperature shipments, and accommodate varying carrier pickup schedules.

Intelligent outbound sequencing retrieves pallets in loading order rather than random storage location sequence. This sequencing reduces staging area requirements and accelerates truck loading. The WCS coordinates retrieval timing with carrier schedules to have pallets ready precisely when needed.

Dutch cold storage facilities often maintain multiple temperature zones – ambient, chilled, and frozen. Pallets moving between zones require careful transfer management to maintain temperature integrity while maximising throughput.

Rapid envelope doors minimise heat exchange during pallet transfers between temperature zones. Moffett Automation integrates these doors with shuttle traffic management, coordinating movements when possible and reduce the frequency of door openings. This coordination maintains cold chain integrity while optimising energy efficiency.

Throughput capacity means nothing if systems cannot operate reliably. Equipment failures, software issues, and maintenance requirements all affect real-world throughput. Building redundancy into system design ensures you achieve projected throughput consistently rather than only under ideal conditions.

Single points of failure create throughput risks. If one shuttle path or VTU lift becomes unavailable, affected pallets cannot move. System design should include alternative routing that maintains operations when individual components require service.

Free-roaming shuttle technology offers inherent routing flexibility. Unlike fixed-track systems that depend on specific path availability, free-roaming shuttles navigate around obstacles and find alternate routes automatically and utilise alternative VTU lifts in the system. This flexibility maintains throughput during partial system disruptions.

Preventive maintenance keeps systems operating reliably, but maintenance activities consume capacity. Scheduling maintenance during low-demand periods preserves throughput when you need it most.

Moffett Automation service contracts include planned maintenance scheduling coordinated with your operational calendar. Preventive service happens during off-peak hours, ensuring equipment reliability without sacrificing throughput during critical periods. Remote monitoring identifies potential issues before they cause unplanned downtime. Taxi pallet shuttle maintenance areas can also be built into each system.

Remote monitoring identifies potential issues before they cause unplanned downtime. Taxi pallet shuttle maintenance areas can also be built into each system.

When issues occur, resolution speed determines throughput impact. Systems that require on-site technician visits for every problem accumulate significant downtime over time.

Remote configuration and fault resolution capabilities allow many issues to be addressed without waiting for physical service visits. Moffett Automation’s 24/7 remote technical support diagnoses problems quickly and implements software-based solutions immediately. This remote support capability minimises throughput losses from system issues.

Implementation completion marks the beginning of ongoing throughput optimisation. Actual performance data reveals opportunities invisible during planning. Improvement processes extract maximum value from your automation investment.

Track metrics that directly reflect throughput performance. Pallets per hour by zone, average retrieval time, VTU utilisation rates, and shuttle idle time all indicate system health. Monitor these KPIs against targets established during planning.

Look beyond averages to understand performance variation. Consistent throughput matters more than occasional peaks. Identify conditions that cause performance to drop below targets and address root causes.

Automated systems generate extensive operational data. This data reveals patterns invisible to human observation – subtle bottlenecks, inefficient routing decisions, shift efficiency patterns and storage allocation opportunities.

Moffett Automation WCS software harnesses this data through machine learning algorithms that refine system operation over time. Traffic patterns improve as the system learns from actual movements. Storage allocation automatically adapts to changing demand patterns. This optimisation extracts increasing throughput from the same hardware investment.

Successful automation often reveals new opportunities. Areas initially left manual may become obvious expansion candidates. Throughput gains in automated zones may expose new bottlenecks in remaining manual operations.

Plan expansion decisions based on concrete data rather than initial projections. Actual throughput performance, ROI achievement timeline, and operational experience all inform expansion timing. Modular system designs make expansion straightforward when the business case supports growth.

ASRS systems do not operate in isolation. Integration with warehouse management systems, enterprise resource planning platforms, and operational processes determines whether automation delivers its full value. Dutch warehouses must address several specific integration requirements.

Your warehouse management system tracks inventory, processes orders, and directs operational activities. The WCS must exchange information with your WMS to coordinate automated and manual operations.

Moffett Automation systems integrate with existing warehouse management and ERP platforms through standard interfaces. This integration ensures inventory accuracy, order processing efficiency, and operational visibility across both automated and manual warehouse zones.

Real-time visibility into system performance supports operational decision-making. Dashboards displaying throughput rates, equipment status, and exception conditions allow supervisors to identify and respond to issues promptly.

Monitoring extends beyond the warehouse floor. Remote access to system status enables support teams to assist regardless of physical location. Moffett Automation’s monitoring capabilities give operations and support personnel the visibility they need to maintain throughput performance.

Many Dutch warehouses serve food, pharmaceutical, or other regulated industries. These operations require documented traceability, temperature monitoring, and audit capabilities that automation must support.

ASRS systems can enhance compliance by recording pallet movements, storage conditions, and handling times precisely. Verified pallet scanning ensures accurate tracking while automated handling reduces contamination risks from human contact. These compliance benefits often justify automation investment beyond throughput improvements alone.

Cold storage operations present unique throughput challenges. Low temperatures affect equipment performance, energy costs amplify inefficiencies, and worker safety concerns limit manual handling options. ASRS retrofits in cold storage facilities must address these specific conditions.

Standard warehouse equipment often falters in cold environments. Lubricants thicken, batteries lose capacity faster, and electronic components may malfunction. ASRS systems intended for cold storage require components rated for low-temperature operation.

Moffett Automation shuttle systems are proven in deep-freeze environments, maintaining high performance under conditions that would disable standard equipment. This cold storage capability ensures throughput targets remain achievable regardless of operating temperature.

Every joule of energy entering a cold storage facility must be removed by refrigeration systems. Inefficient automation adds heat load that increases operating costs and may exceed cooling capacity.

Lightweight shuttle design reduces energy consumption per pallet movement. Intelligent traffic management minimises total shuttle travel distance and therefore total energy input. Eliminated forklift traffic removes a significant heat source. These efficiency measures help cold storage facilities approach net-zero energy operation for storage and retrieval activities.

Manual cold storage work exposes employees to health risks from extended low-temperature exposure. Labour regulations limit work time in cold environments, and worker turnover in these roles remains high across the industry.

Automation dramatically reduces the number of personnel required in temperature-controlled zones. Employees focus on supervision and exception handling rather than routine pallet movements. This reduction in cold exposure improves worker safety while addressing chronic labour challenges in cold storage operations.

Retrofitting existing facilities with automated systems creates safety challenges different from new construction. Mixed traffic between automated equipment and personnel, transition hazards during phased implementation, and integration with existing safety systems all require attention.

Clear physical separation between areas where automated equipment operates and zones with personnel traffic prevents accidents. Fencing, light curtains, and controlled access points establish boundaries that protect workers while allowing necessary system access.

Moffett Automation installations include robust safety measures designed for each facility’s specific configuration. Safety fencing, automated gates, and muting sensors create secure boundaries while maintaining operational flexibility for maintenance and exception handling.

Emergency situations require immediate system response. Fire alarms, medical emergencies, and evacuation orders must trigger appropriate automated system behaviour. Integration between facility safety systems and ASRS controls ensures coordinated response.

Define and document emergency procedures before system commissioning. Train personnel on emergency protocols specific to automated operations. Regular drills verify that procedures work as intended and that staff respond appropriately.

European safety regulations require CE marking for automated equipment. Systems must meet applicable standards for machinery safety, electromagnetic compatibility, and low-voltage equipment. Compliance documentation supports regulatory inspection and liability protection.

Work with automation vendors who understand European regulatory requirements. Compliance should be built into system design rather than addressed as an afterthought. Moffett Automation systems meet applicable European standards and include documentation supporting regulatory compliance.
