DMD Industry 4.0 & Data Analytics

Question 1

What does 'Industry 4.0' primarily refer to in digital manufacturing?

Accepted Answer

The fourth industrial revolution integrating cyber-physical systems, IoT, cloud computing, and AI into manufacturing

Answer

Industry 4.0 describes the current transformation of manufacturing through interconnected smart machines, data analytics, and cyber-physical systems.

Question 2

What is the Industrial Internet of Things (IIoT) in a manufacturing context?

Accepted Answer

The network of sensors, machines, and devices in a factory that collect and exchange data over the internet

Answer

IIoT connects manufacturing equipment, sensors, and systems to collect real-time operational data that can be analyzed to optimize performance.

Question 3

Which type of analytics predicts future equipment failures before they occur by analyzing historical and real-time sensor data?

Accepted Answer

Predictive analytics

Answer

Predictive analytics uses machine learning models trained on historical failure data to forecast equipment breakdowns before they happen.

Question 4

In manufacturing data analytics, what does OEE stand for and what does it measure?

Accepted Answer

Overall Equipment Effectiveness — the product of Availability, Performance, and Quality rates

Answer

OEE = Availability × Performance × Quality and is the gold-standard metric for measuring how effectively manufacturing equipment is utilized.

Question 5

What is 'edge computing' in the context of smart manufacturing?

Accepted Answer

Processing data locally on or near the machine rather than sending it to a remote cloud server

Answer

Edge computing processes sensor data at or near the machine, reducing latency and bandwidth requirements compared to sending all data to a central cloud.
