<dc:description>This paper describes the problems associated with the implementation of a real-time&#xd;
optimization (RTO) decision support tool, for the operation of a large scale hydrogen&#xd;
network of an oil refinery. In addition, a formulation which takes into account&#xd;
the stochastic uncertainty of hydrogen demand, due to hydrocarbons quality change,&#xd;
is described and further studied, focusing on its utility in the decision-making process&#xd;
of operators. An integrated robust data reconciliation, and economic optimization,&#xd;
considering plant-wide uncertain parameters is presented and discussed. Moreover,&#xd;
stochastic uncertainty in hydrogen demand is assessed for its inclusion within&#xd;
the RTO framework. A novel approach of the decisions stages at hydrogen producers&#xd;
and consumers is proposed, which supports the formulation of the problem as&#xd;
a two-stage stochastic non-linear program. Representative results are presented and&#xd;
discussed, aimed at assessing the potential impact in the hydrogen management&#xd;
policies. For this purpose, the value of the stochastic solution, perfect information,&#xd;
and expectation of the expected value are analyzed. Complementarily, a risk-averse&#xd;
formulation is presented (value-at-risk and conditional-value-at-risk) and its results&#xd;
compared against the formulation without risk considerations. Finally, some attention&#xd;
is given to future directions of this decision support tool, based on these work&#xd;
contributions, including the importance of the decision makers’ participation in the&#xd;
analysis of the potential impact of risk-averse results.</dc:description>
