Digital work instructions, cobots, radio frequency identification (RFID), augmented reality (AR) and other Industry 4.0 technologies can help. These technologies are designed to provide cognitive and physical support to people on the assembly line. How can engineers decide when such technologies are a worthwhile investment?
In a case study, industry 4.0 technologies application in a gear-box assembly line was studied.
Seven Industry 4.0 technologies were considered: RFID, digital work instructions, pick-to-light technology, AR, cobots, automated guided vehicles, and ergonomic manipulators.
Four quantitative criteria were used to rank the technologies: total investment cost, worker effort, workspace utilization and cycle time reduction.
RFID is one of the most important technologies for identifying and tracking assemblies in a production system. It provides precise information about the locations or states of goods in real-time and serves as a capstone for the establishment of the IoT within production.
Digital instructions are proven to reduce the assembly time and errors with complex assemblies.
Pick-to-light systems use LEDs on racks or shelves to show assemblers where to pick parts for an assembly and how many to retrieve. The lights guide assemblers through each step in the process. These systems are often connected with warehouse management systems.
AR also offers the possibility of significant improvement in cycle time, error rate, mental strain, worker focus.
Cobots are particularly desirable when people are confronted with heavy loads and repetitive, tedious activities. People can share the same workspace with the cobots, allowing managers to allocate tasks in a more flexible, efficient way.
AGVs can eliminate the need for people to transport parts and assemblies to and from the assembly line.
The ergonomic manipulator is an electronic device developed to improve ergonomics at the fifth assembly workstation. The device reduces the amount of physical effort needed to handle heavy components that must be mounted to the gearbox.
This article is a summary of a research paper co-authored by Aljinovic, Nikola Gjeldum, Ph.D., Boženko Bilic, Ph.D., and Marko Mladineo, Ph.D.

After visiting one of the Toyota brand assembly plants and three tier-two suppliers, I can unequivocally say that Toyota very clearly talks about cost management.
Cost management and productivity improvement were on the lips of every executive that we met with at each of the four companies.
