Mathematical Methods for the Multi-Criteria Optimization of Structure and Management of Energy Efficient Gas Supply Chains

While the problem of the optimal operation of gas networks has been the object of a large amount of research work, the inclusion of market mechanisms and environmental issues, leading to more complex models resulting in stochastic multiobjective optimization algorithms, has not been considered in its generality. The goal of this article is double: to identify the most general models and algorithms, capable of providing a complete decision support tool, and to show how simplified models can be obtained from them if the complexity of the network makes it necessary to reduce the computational burden.
