Prioritization is the process of giving priority to something more than the other based on certain criteria. It can be depicted as a matrix where each row is defined an entity with a specific priority according to the values of cells in each row.
There could be constraints on the values of the variables (max, min), and possibly on other issues.
The objective is to maximize priorities and minimize losses. As an example you have many airlines (rows) each has specifications (cells in each row) such as alliance with national airline (give 1 for yes or 0 for no), paying fees on time (give 1 for yes and 0 for no)….etc (these are considered the chromosomes or the population individuals)
The objective is to give priority in service for airlines with high priority.
This is just an example which can be implemented easily using MATLAB GA
