Many warehouses do not automate every storage and transport area at the same time. A phased AGV rollout can reduce operational disruption and allow the warehouse team to validate each stage before expanding automation.

However, phased deployment requires more than dividing the warehouse into several physical areas. The fleet, software, traffic rules, interfaces, and operating procedures must be designed so that each phase can connect to the next.

Why Use a Phased AGV Rollout?

A phased project can allow the warehouse to start with a defined operating area and expand after the initial workflow has been validated.

Potential advantages include:

• Lower initial operational disruption

• Earlier validation of the automation workflow

• Opportunity to improve processes before expansion

• Controlled staff training

• Progressive integration with WMS and other systems

How Should the First Zone Be Selected?

The first zone should not automatically be the largest warehouse area.

Consider:

• Transport volume

• Process stability

• Available floor space

• Pallet standardization

• Traffic complexity

• WMS readiness

• Availability of staging areas

• Potential for future expansion

A controlled, representative zone can provide better information for later phases than a highly complex area with many exceptions.

What Should Be Standardized Before Expansion?

The first phase should establish reusable standards wherever possible.

These may include:

• Pallet handling rules

• Task interfaces

• AGV traffic rules

• Safety procedures

• Charging strategy

• Exception handling

• Data interfaces

• Operator procedures

Standardization makes the second and third phases easier to plan.

How Should WMS Integration Be Planned?

A common mistake is to treat each rollout phase as a separate software project.

If the warehouse eventually intends to operate one integrated automated fleet, the system architecture should be considered from the beginning.

The initial phase should clarify how future zones will be added without creating separate task-management processes.

Can Different Warehouse Zones Use Different AGV Routes?

Yes. Each zone may have its own traffic pattern, storage rules, and operating restrictions.

However, the fleet-control system should understand how these zones connect.

For example, a pallet may move from:

Receiving Zone → Automated Storage Zone → Shipping Zone

If only the storage zone is automated initially, the warehouse should still consider how future AGV routes will connect receiving and shipping operations.

How Should Additional AGVs Be Added?

Fleet expansion should consider more than vehicle quantity.

Additional vehicles can affect:

• Traffic density

• Charging demand

• Intersection behavior

• Fleet communication

• Staging capacity

• Task allocation

The supplier should confirm how additional vehicles are commissioned and how the existing fleet continues operating during expansion.

How Should Each Phase Be Accepted?

Each phase should have its own acceptance criteria.

Possible checks include:

• AGV navigation

• Pallet pickup

• Pallet placement

• WMS task execution

• Safety functions

• Charging

• Exception handling

• Operator procedures

Acceptance should be based on the actual operating conditions of that phase.

How Should the Warehouse Operate During Expansion?

The warehouse may need to operate manual and automated processes simultaneously while the next zone is being prepared.

The transition plan should therefore define:

• Temporary manual routes

• Temporary staging

• AGV operating boundaries

• Construction or installation areas

• Staff access

• Emergency access

Temporary operating conditions should be treated as part of the project plan rather than left to warehouse operators to resolve on their own.

What Should Be Reviewed After Each Phase?

Before starting the next phase, review actual operational data.

• AGV utilization

• Task waiting time

• Manual interventions

• Traffic congestion

• Charging performance

• WMS exceptions

• Pallet handling errors

• Operator feedback

The purpose is to identify problems that should be corrected before they are replicated across the next automated zone.

What Should Be Included in the Long-Term Expansion Plan?

When selecting the initial AGV supplier, discuss the intended future state even if the first purchase is relatively small.

Important questions include:

• Can future warehouse zones use the same fleet software?

• Can additional vehicles be added later?

• Can new storage locations be configured?

• Can new WMS tasks be added?

• Can the network support the expanded fleet?

• Can charging infrastructure be expanded?

• Can the safety system accommodate additional operating areas?

A phased rollout works best when the first deployment is designed as the foundation of the future warehouse automation system rather than as an isolated project.
