27 Summery: Model-based Engineering Proposition of Bosch Rexroth Leading in Drive & Control solutions Component, Module and System Supplier Services (, System Engineering, ) Gain of Model-based Engineering Better products (component optimization) Better market fit (virtual prototyping of new concepts) More effective engineering services More successful customers - strong cooperation - effective communication - cutting edge solutions The Model is the vehicle to bring the BR-technology into our customers application.

28 Functional Requirements on a Model-based System Engineering Environment System Modeling Requirements Engineering System Topology Test cases Multi-physics modeling Drives (Hydraulics, Pneumatics, Electrics, Power train) Multi-body Dynamics (rigid, flexible, contacts) Controls, Sensors HiL/SiL Simulation Synchronized bus-communication Real-time Parameter Application µcontroller Code Generation

29 Non-Functional Requirements on a Model-based System Engineering Environment Modeling/Simulation functionality shall be: transparent performant extensible customizable Integration Data/Model exchange - non-proprietary - standardized - well supported Open interfaces reusable, redistributable, freely available

30 Conclusions SysML and Modelica: Have the potential to fulfill the requirements on a standardized common modeling language in the field of System Engineering Enable an effective communication of Bosch Rexroth and his customers OpenModelica: strengthens the Modelica language makes the model-based engineering affordable (even for small businesses) serves as a default interpreter of the Modelica language decreases the dependency on commercial simulators provides a good starting point for powerful in-house simulation tools

31 Outlook OpenModelica: Level 2 Member of the OSMC Contributes to the OpenModelica Compiler (i.e. Solver Interface) Cooperation with the OSMC members Integration of the OpenModelica Compiler into the Bosch Rexroth in-house simulation platform D&C Engine OPENPROD ITEA2 project Partner and national coordinator of the project proposal Work packages related to demonstrators and model reduction MODELISAR project Partially involved into the design of the Functional mock-up interface
