How can one optimize kernel parameters to enhance performance in a highly specialized real-time Linux environment? I really need, if someone know please help!

Using kernel parameters is usually targeted at quite specific issues. They could about booting, graphics, networking, power management, devices, the cpus, the memory and numerous other aspects. I guess the first port of call would be to peruse the kernel documents on kernel parameters to gain a sense of what they can apply to and manipulate. See here:
There are many kernel parameters that are undocumented, especially those which apply to particular software and hardware that either hasn't made into the kernel docs for one reason or another, or are specific to developments that are on-going or at the frontier. Parameters in these latter cases are often found in developer's or user's mailing lists or forums, but not always.

Given those considerations the idea to "optimize kernel parameters to enhance performance" doesn't look to have a simple overall answer. Rather, there'd likely be a more specific answer if the performance of one or more particular aspects of functioning were identified.
Optimising kernel configuration options, such as in the SCHED configuration options mentioned in the first link in post #2 by @f33dm3bits, is likely to be a more effective approach to optimisation compared with the sole use of kernel parameters, so perhaps that's worth considering in the optimisation stakes. That kernel configuration approach however, involves building kernels rather than just adding parameters to existing or default kernels. Using relevant kernel parameters with such optimised built kernels sounds like a more useful approach for optimisation.
This looks a lot like a homework question.
