Parameters for updating the rolling horizon model.

${\overline{E}}_{ir{t}^{*}}$	The amount of resource $\in R_{DUR}$, which are available in region $i\in I$ at the beginning of period $t^{*}$.
${\overline{C}}_{ir{t}^{*}}$	The capacity of resource $r\in R_{SER}$ in region $i\in I$ at the beginning of period $t^{*}$.
${\overline{X}}_{ik{t}^{*}}^s$	The number of hospitalized patients in type $k\in K$ at region $i\in I$ at the beginning of period $t^{*}$.
${\tilde{X}}_{ikt}$	The number of accepted patients in type $k\in K$ in region (hospital) $i\in I$ in periods before $t^{*}$, which they will be discharged at period $t$ based on ${\Gamma }_k$. This parameter is zero for $t\ge t^{*}+{\Gamma }_k.$
${\widehat{X}}_{ikt}$	The number of accepted patients in type $k\in K$ in region (hospital) $i\in I$ in periods before $t^{*}$, which is supposed to be discharged in period $t$ based on ${\Gamma }_k$, but they are discharged in periods before $t^{*}$.
${\overline{Q}}_{irt}$	The number of healthcare resources $r\in R_{TR}$, which are transshipped from other regions to region $i\in I$ in periods before $t^{*}$ and will be available at the beginning of period $t\in T$.
${\overline{W{}^{\prime }}}_{ik}$	The number of patients in type $k\in K$ at region $\in I$, which are not accepted in any regions in period $t^{*}-1$ (previous period of the beginning period).
