Inverse Optimisation and Planning

A Multi-Objective (MO) Problem

Example of

a bi-objective space (f

1

, f

2

)

. We assume as mentioned already the minimization

problem.

The

Pareto Front

is the boundary between the points P

1

and

P

2

of the

feasible set F

.

Solutions 1

and 3 are

non-dominated Pareto optimal solutions

.

Solution 2 is

not Pareto Optimal

as

solution 1 has simultaneously smaller values for both objectives.

There is no reason why

solution 2 should be accepted rather than solution 1.

Therefore the aim of MO optimisation is

to obtain a representative set of non-dominated solutions.
