Please add some more information for your question so we can better help you.
A fittness function is just like any other function except it is expected to return a specific output that will be used by whatever function is calling the fittness function. Looks like you need to implement the function in the image you attached.
By the way, windows have a snipping tool that can easily capture screenshots without needing to use your camera.

Hello Feng
it is a simple problem. we just have to write these equations. which is the main problem for me now.
No of vehicle = 8
We have distance matrix
TIme depedent function of speed need to be made.
i have attached the refernce paper which i am following to solve the problem.
link of Genetic algorithm solver in matlab.
This will give some more insight in this regard.

Although I have implemented a fittness function with genetic algorithm but I never used the GUI. I just straight up programmed it. I am not familiar with the GUI part of the GA or GAmultiobj. Nevertheless, you can first try to create a simple error function that returns anything and see the results for yourself as a start.
