Automatic decomposition of simulation model

A computerized apparatus having a processor, the processor being adapted to perform a method for decomposing a simulation model, the method comprising:

• obtaining the simulation model;
• automatically decomposing the simulation model into a predetermined number of co-simulation components, wherein each co-simulation component is allocated to a different simulation platform, wherein said automatically decomposing comprises:
• defining a target optimization function, wherein the target optimization function computes an estimated run time of the simulation model, wherein the target optimization function is based on a communication time within each co-simulation component and a communication time between each pair of co-simulation components;
• and
• determining a decomposition of the simulation model that optimizes a value of the target optimization function;
• and
• executing the decomposed simulation model by executing in parallel each co-simulation component on a different simulation platform, whereby the simulation model is executed in a distributed manner.

A computer program product for decomposing a simulation model, the computer program product comprising a non-transitory computer readable storage medium retaining program instructions, which program instructions when read by a processor, cause the processor to perform a method comprising:
