Scala is awesome for real-world implementation to solve all sorts of problems!
Audi, car manufacturer use Scala to help them with solving issues and in this talk by Christian Raimann and Christina Stamm at Scala Days Berlin you'll find out exactly how they do this.
Scala at Audi Optimization of assembly lines
The process of assembling cars is highly complex. A car manufacturer like Audi builds a lot of derivatives on just a few assembly lines. One of the problems to solve is the question which car to build on which assembly line to achieve the various optimization goals like minimizing the number of parts, that have to be provided per line.
This talk is about a real-world implementation in Scala to solve that problem. In particular it will describe two approaches, a distributed solution on top of Apache Spark and an in-memory implementation with plain Scala, and pointing out their pros and cons.
