The rise of Heterogeneous Fleet Management Systems
Picture this: a warehouse facility where cart tuggers, picking robots, autonomous pallet movers, cleaning robots, and people all work side by side. This reality, which not too long ago was possible only in our imagination, exists in a growing number of facilities.
Autonomous Mobile Robots (AMRs) have made huge strides over the past few years and are a key element in warehouse automation efforts. According to Gartner, 96% of their supply chain survey respondents had invested or were planning to invest in robotics over the next two years. What’s more, 93% of the companies who have already introduced robots to their operations plan to expand their fleet sizes and introduce additional use cases.
Growing fleets and the variety of use cases have the potential to create chaos. Robot activities need to be orchestrated and synchronized both from a process and operational point of view. Different tasks need to be synchronized to ensure the continuity of business flows. Robot movement needs to be controlled and synchronized to avoid congestion or collisions.
To date, most AMR vendors offer some level of fleet management software that helps manage their robots. The problem is that these systems are mostly vendor-specific. To manage an increasingly diverse robot fleet there is a need for a system that can manage robots from multiple vendors in a shared space – a Heterogeneous Fleet Management System (HFMS), or Multi-Agent Orchestration Platforms as Gartner calls them.
What is a Heterogeneous Fleet Management System and why is it needed?
Simply put, a Heterogeneous Fleet Management System ensures the efficient and continuous operation of multiple robots from different vendors in a shared space. It is the grand orchestrator that ensures business KPIs are met safely and efficiently.
Specifically, an effective HFMS contains a range of functionalities that ensure smooth fleet operation. Some of these tasks may seem straightforward or sound similar to vendor-specific Fleet Management Systems, but the difference is that they must apply to any robot type or make in the fleet – and there’s the rub!
Why do you need a Heterogeneous Fleet Management System?
Lack of heterogeneous fleet management can highly reduce efficiency. Task allocation and prioritization may be suboptimal, processes may not be synchronized end to end and uncoordinated use of shared resources may result in delays, deadlocks and unnecessary idle times. What’s more, the need to configure and operate multiple discrete systems creates employee overhead and increases the chance of errors. Heterogeneous Fleet Management systems improve efficiency, contribute to operational stability and continuity, allow customization, and ensure business agility.
Key functionality of a Heterogeneous Fleet Management System
Fleet status monitoring – Real-time dashboards, location tracking, alerts and notifications, logging, and health monitoring.
Fleet control – Basic commands for both individual AMRs and the fleet as a whole, task dispatching, and remote recovery.
Traffic management – Setup of standard traffic rules as well as conflict resolution strategies.
Tasks management – Task optimization, task queuing, and intelligent task assignment based on the fleet state.
External integrations with WMS, WES, WCS, ERP, and a variety of IIoT (Industrial Internet of Things) devices, such as doors, elevators, conveyors, scanning machines, sorting machines, and more. This integration should allow both the flow of information and control commands in real-time.
Vendor-agnostic setup and deployment – Enabling full definition of the environment, AMR onboarding, unified task definition, rules, etc. for all AMRs using a single pane of glass. Vendor-agnostic setup does not mean that you can set up each AMR separately in the same tool. It means that you can set up rules and infrastructure once and apply them to all AMRs. You can create compound tasks and check the setup on one AMR against the other for conflicts. It is a truly holistic setup.

A maturity model for HFMS: making sense of different solutions
HFMS are highly sophisticated systems that combine various technology types and approaches. While several systems have been introduced to the market, they widely differ in their ability to provide true heterogeneous fleet management. To help AMR operators and integrators better understand the differences between these solutions and the value they deliver, we suggest a four-level maturity model:
