Technical issues• Missing features in Umple

(under development)• Class abstraction• Generics• No Multiple Interface Implementation• Exception Handling

• Oracle database server crashed• Inaccessible Real-Time data for Neural

Networks learning

19

Decisions and Solutions• Code generation from model • Implemented the following design patterns:• Factory Pattern• Repository Pattern• Singleton Pattern• Observer Pattern

20

Some more issues• Some ill-performing team members• Language semantics• Cultural misunderstandings

21

Results Complete Umple model as

Product Line Core Developed 3 working instances Extended the requirements from

Customer Neural Network for Arrival Time Prediction Quickest route finding
