In the IoT revolution for supply chains, visibility has become the eighth wonder of the world. Visibility enables shippers, carriers, and anyone delivering goods to know where they are and how they are performing at any given time. In the past, such visibility has been delayed – and in some cases it still is. But we are entering the age where supply chain monitoring is done in real-time, continuously, for single shipments or groups of shipments. Visibility and monitoring are not only gaining complexity, they are also becoming more effective than ever before; as a result, shippers expect significant gains from it.
Nowadays, shippers are most concerned with the quality of their cargo at arrival and the assurance that the cargo remains in its intended condition. To ensure this, data-centered thrust in the age of IoT strives to drive supply chains everyday by providing robust monitoring. When cargo is monitored through wireless sensors and other devices, information such as temperature and humidity of an environment, as well as other conditions like liquid levels, product, weight, or any other important parameters, are maintained to ensure safe arrival.
Cameras also provide another means of visibility by observing goods in transit. These devices visually monitor conditions and offer observers information to make quick decisions if necessary. This includes keeping an eye on storage configurations, pallet loads and their integrity, and any damage from combustion or other destruction that may occur. This method allows for early intervention to prevent further damage from taking place.
There are several ways that monitoring may take place. Each way offers different advantages to many in the extended supply chain, including shippers, carriers, and logistics agents who are responsible for the cargo.
The first type of monitoring to be introduced to the supply chain was single point monitoring, where the cargo is observed at one point in time. Such monitoring may or may not recur on a regular basis. It may be quite effective when limited time is available to check on cargo integrity. In other words, the shipped goods can be checked whenever desired.
However, the data may not be in real time and may be replicated from a signal downloaded from a server or, in some cases, a satellite. The information afforded by single point monitoring may be observed at a later date, but it may also be a time lapse image of the cargo with a delay between when the cargo is observed and when the actual photograph was taken via the camera shot.
Single point temperature monitoring typically occurs at time of shipment and delivery.
The second type of monitoring is continuous monitoring. Such monitoring may be delayed or in real-time. An information feed about the transported goods is “always on” and available to the observer. It allows the observer to monitor goods shipped wherever, whenever, and however the responsible parties wish. Such information may be fed into a dashboard, which may include a series of screenshots. The observer may query or recall the screenshots as desired, individually or all together in one single view. It's quite effective in ensuring confidence that the cargo is intact and is being satisfactorily transported.
Continuous temperature monitoring provides proof of temperature control from shipment to delivery to validate inventory temperature throughout the entire transport chain.
The third type of monitoring is real-time, continuous monitoring. With this type, data is fed as it happens. The observer knows what's going on at present, no matter when or where the cargo travels around the world. This is ideal for quick action to control the cargo shipments should anything occur that may require immediate intervention, such as making adjustments to the environment (temperature or humidity) or another procedure.
For example, if a fire breaks out, or if the cargo is leaking or becomes disheveled due to a vibration, somebody can intervene and act immediately, thanks to real-time monitoring. This may also take place on an “as needed” basis as continuous monitoring may not be necessary but may be viewed as conditions dictate – for instance, if the transportation asset goes through a storm, or if an accident occurs, or any other circumstances which may signal that the cargo could be in jeopardy. Continuous monitoring allows more control as needed, in real-time.
Real-time continuous monitoring offers additional monitoring capabilities through multiple sensors, and provides immediate visibility into temperature data.
These methods provide options for the observers to monitor the shipment of their goods and enable a better pathway to full visibility and control. Now, a large volume of cargo can be viewed and monitored with the use of more efficient monitoring options and technology through sensors made possible by IoT, dashboards, and advanced analytics. These methods also allow observers to see and monitor goods from one place and across different modes of transportation. With more advanced technology and new methods available to monitor transportation, observers have maximum visibility and control of shipments under their responsibility.
In the future, shippers will seek carriers and transportation agents who understand the value of monitoring and have the hardware and software to support the transportation of goods – intact, in top condition, and to the satisfaction of the end-users and customers at the end of the supply chain.
