15. How to solve it? Hybrid solution approach (General idea):
Exact methods
Good for solving limited-size problems
Metaheuristic methods
Can deal with large-scale problems
Hybrid solution approach (General idea):
Decompose the problem into sub-problems, each associated with a period
The sub-problems are of reduced size, so an exact method can be used
Combine the solutions of the sub-problems to get a solution of the original problem
Improve this solution using a metaheuristic method
