I made a Simulink model to represent Ship performance which contains submodels. Each submodel represents a certain component of the ship system and has a different time response.

How should i decide the overall time step of my developed ship simulator ? Also how can i assign or give each submodel its corresponding time step ?

You can use the rate transition block in the parent model to control the execution of each block as well as the execution of the referenced models. The example here illustrates how to use rate transition block.

Thank you Sainath for your kind reply and help. If i have different sub-models with different time step, the global simulation time should be defined by the largest or the smallest time step of the used sub-models?
