Automotive assembly lines have operated the same way for a century. Each worker takes charge of a single process and installs parts in vehicles as they move on a chain-driven or skillet conveyor.

For the last 100 years, dryers, ovens, refrigerators, washing machines and other household appliances have performed the same basic functions, such as keeping food hot or cold and getting clothes wet and dry. But, a new breed of “smart” appliances is emerging, thanks to advanced sensor technology and the Internet of Things (IoT).

Manufacturers today are producing a wider range of products than ever. Life cycles are shrinking and demand for customization is increasing. As a result, assembly lines must be as flexible as possible without compromising efficiency. That’s why companies producing everything from pumps to pistols and caskets to chainsaws depend on mixed-model assembly.
