Sensitivity analysis
### Sensitivity analysis

The multiple objective optimization problems involve computing the [tradeoff](/wiki/Tradeoff "Tradeoff") between the costs and benefits resulting in a set of solutions that can be used for sensitivity analysis and tested in different scenarios. But there is no single optimal solution that will satisfy the global optimality of both objectives. As both objectives are to some extent contradictory, it is not possible to improve one objective without sacrificing the other. It is necessary in some cases use a different approach. (e.g. [Pareto Analysis](/wiki/Pareto_analysis "Pareto analysis")), and choose the best combination.
