OPTIMIZATION PROPLEM SETUP FOR A POWER MANAGMENT SYSTEM

The above is my objective function

Whereas:

m is the index of engine

M the total number of engines installed per one side

J number of modes of operation

j, the index of mode of operation

AND

My objective is to creat MATLAB CODE that find all values of X , Y and select MCR that minimize Total Fuel Consumption through all modes of operation . So, X, Y and MCR are decision variables. Other variables are dependent variables

I AM NOT LOOKING FOR Numerical Answer for this examble, i put it for illustration. i have started by defining variables as symbolic variables but i got stuck when i creat the main objective function

this is part of my project, the whole proplem is much complex with more details.

thank you in advance

my regards
