How IoT supply chain monitoring improves logistics

Track your assets in real-time with IoT supply chain monitoring for increased revenue, efficiency, fraud and tampering detection, and peace of mind.

In many industries, supply chains continue to be remarkably opaque. At their best, they run like perfectly orchestrated systems, the result of decades of process optimization. Still, much can happen to raw materials and finished goods as they transit to and from manufacturing sites. They can get damaged, degraded, accidentally mixed up, deliberately exchanged, lost, stolen, or simply delayed, each of these events requiring immediate remediation to avoid further delays. With the prevalence of just-in-time manufacturing and the subsequent reduction of storage capacities, early deliveries can be as disruptive as late ones.

The Internet of Things is bringing a new degree of visibility and predictability to all stages of the supply chain, combining extensive sensing, satellite-based positioning, wireless communication, and cloud platforms for data storage, processing, and visualization. By prying open the black box of conventional supply chains and shining light into all its processes, a growing number of industries are adopting IoT supply chain monitoring to save time, money, nerves, and in the pharmaceutical and medical sectors, lives.

A diverse landscape

Assets are at the heart of supply chains – and they are a mixed bag. Transported in bulk, packaged into bags or boxes, stacked onto pallets, loaded into cargo containers or unit load devices used in aviation, these assets traverse oceans, continents, factory floors, warehouses, and retail locations on the way to their next, sometimes final, destination. Vaccines and fresh fish may require varying degrees of cooling, fragile assets many need careful handling, and “attractive” products heightened levels of security against tampering, corrupt misappropriation, and theft.

This diversity in terms of packaging, transportation, and monitoring needs calls for versatile asset tracking solutions capable of locating the assets across a range of environments, indoors, outdoors, on rail, road, and sea. They need to be able to upload location and, potentially, monitoring data to the cloud. And, because of the global nature of today’s supply chains, they need work everywhere on the planet.

Technological considerations

Regardless of where they are deployed, IoT asset trackers are made up of a common set of building blocks and are subject to a common set of requirements. Deciding which positioning solutionswireless communication technologies, and services are the best match for a given use case requires carefully weighing competing interests in terms of edge versus cloud computing performance, geographical coverage, technical features, end device size, and cost.

  • Positioning: To provide real-time insights into their whereabouts, assets (or the containers they are transported in) need to be tagged with asset tags featuring a positioning solution.
    Decision criteria include availability and coverage (geographical, indoor/outdoor), performance (accuracy, reliability, update rate, battery-life), security (jamming and spoofing mitigation), size, and cost.
  • Wireless communication: IoT-based asset trackers generally require a wireless data link to transmit sensed data and position to the cloud, as well as to simplify commissioning, configuration, and maintenance, e.g., using smartphones or tablets as human-machine interfaces.
    Decision criteria include range and coverage (geographical, indoor/outdoor, remote), bandwidth requirements, architectural considerations (device to cloud versus device to gateway to cloud), network size, ease of deployment and scalability, power requirements, security, and cost.
  • Sensing: Depending on the scenario, asset trackers may require additional sensors to detect motion, shocks, temperature, pressure and humidity, and other metrics needed to monitor the state of assets while in storage or in transit.

Balancing cost, size, and performance

In an upcoming series of blogs, we will explore three broad categories of asset tracking applications and investigate strategies to optimally balance cost, size, and performance for each specific use case.

In our first blog, we will focus on solutions designed primarily to track the geographical location of large assets – intermodal containers transported across oceans on cargo ships or across continents on semi-trucks, as well as ULDs using in aerial logistics.

The second blog will explore solutions for a growing number of smaller assets requiring sensor-based monitoring in addition to geographical tracking and cloud connectivity.

And the third blog in the series will look at assets at rest, whether in outdoor container terminals or in indoor logistic hubs, factory floors, or warehouses.
