I would like to know if there is any theory behind designing the fixation for any part. To optimise the number of mounting holes and fasteners.
If so what is it called and where can I get it? Please help me.

It depends on the context. In structural engineering it means a connection that would be strong enough to develop a plastic hinge after the applied stresses surpass the design stresses.
In trusses and spaceframes a joint that is not pinned can be designed to be fixed up to a certain limit and then fail in a controlled, energy consuming, ductile way.
In Machinery a fixation usually means minimum strength that can resist all the forces, vibrations and torques, so it is important the node be bolted in a balanced and symmetrical way so that the center of rigidity of the part coincides with the axis and point of action of the load, it was designed to support.
There are rules on how to place the bolts and fasteners so that they contribute evenly to rigidity.
Here is AISC handbook of steel connections. Connections in steel structures
