Twenty billion. That's the estimated number of devices that will be connected to the Internet by 2020, according to analyst firm Gartner (currently, 5 billion connected things are in use). It's part of the global push behind what's known as the Internet of Things (IoT), defined by Gartner as "the network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment." Taking that definition to the next logical step, the McKinsey Global Institute adds that IoT devices "can monitor their environment, report their status, receive instructions, and even take action based on the information they receive."
In other words, if and when IoT technology takes root and is applied where appropriate, the status of raw materials, components, production machinery, finished products, material handling equipment, packaging, and transportation vehicles—basically, the entire supply chain—can be known and communicated at any time, from any place.
Although the buzzword itself is new, the core concept to the IoT has been around for decades. As Steve Banker, vice president, supply chain management with industry analyst firm ARC Advisory Group, notes, the IoT is "nothing new in logistics." As far back as 1975, he points out, companies were taking radio-frequency scans and using that data to improve warehouse processes.
However, while the basic data collection technology has been in place for at least 40 years, it hasn't been leveraged to its full potential until quite recently.
As exciting as the potential of the IoT may be, though, the reality is that nobody can quite yet imagine what the killer apps will be for their industry, notes Greg Braun, senior vice president with C3 Solutions. But the consensus appears to be that, at least within supply chain circles, "end-to-end visibility has long been the holy grail" and that's where you'll find the earliest examples of IoT technology being deployed in the real world, according to Braun.
IoT in the Real World
Here are a few examples of how companies are using IoT to improve areas of their logistics operations:
- Nestlé, one of the world's largest food producers, has deployed wireless vehicle management systems (VMS) developed by I.D. Systems on more than 2,000 industrial trucks across more than 60 manufacturing and distribution facilities. The VMS automatically uploads vehicle data, reports vehicle problems electronically, and schedules maintenance based on actual usage. For Nestlé, the VMS helps ensure that only trained personnel have access to the vehicles, and that safety protocols are followed before the vehicles are operated. The VMS includes a smart impact sensor, as well as automatic shut-off functions when trucks are left idling, which helps reduce fuel consumption and emissions.
