I want to keep a track of how many times my simulink model is run ? without using persistant variable and I also want to reset a variable when the simulink model is closed ? Please let me know if you have any ideas to implement this logic.

Generally speaking, it's impossible that you record statical value without using persistent variables.
If you can use Base Workspace variables, you can utilize Model Callbacks.

Example:
StartFcn : count up the counter.
CloseFcn : reset the counter to zero.
