Warehouse Management System (WMS) implementations can be challenging, and so no company looks to make such a technology move unless it has real problems with its existing system or a very strong ROI from upgrading its current technology.

But there must be a lot of that going around. Analyst Dwight Klappich, who covers the WMS space for Gartner, tells SCDigest he continues to field many calls from clients considering selection of a new WMS.

There are in fact a wide number of potential factors that driver companies to look for a new WMS solution, which we have handily grouped into 10 different logistics scenarious below.

Does the US only have to work through a truck driver shortage for another decade or so?

Perhaps, as German auto and truck maker Daimler said last week it was targeting 2025 for release of a self-driving truck into the marketplace.

The Mercedes-Benz Future Truck 2025 has successfully completed its first journey on a highway in Germany, thanks to new technology borrowed in large part from a system already available on Daimler's new Mercedes-Benz S-Class luxury sedan.

In addition to the Mercedes brand truck in Europe, the company sells Freightliner brand tractors in the US and the Fuso brand in Japan. Daimler is actually the world's largest truck maker.

The system makes use of already-available driver assist technologies, such as automatic braking, stability control and lane-warning systems, but adds a variety of radar systems to the mix.

In order to allow the truck to autonomously drive alongside other cars, what Daimler calls the Highway Pilot uses a combination of vehicle-to-vehicle communication via Wi-Fi (with a range of 1,640 feet), lateral radar on both sides of the truck (with a range of 197 feet) and full range (820 feet) and short-range (230 feet) radar mounted on the front of the truck. The truck also uses a front stereo camera, mounted just under its windshield.
