\section{Objectives (Most relevant Array Performance Parameters)}  This section aims to include all the array performance objective that might be influenced by design choices.  \subsection{Minimize Brightness Sensitivity Limit}  Let $\eta_s$ be the system efficiency. If we assume each aperture has the same system temperature $T_{sys}$, System Equivalent Flux Density $SEFD$,  are observing the same bandwidth $\Delta\nu$, during the same correlator accumulation time $\tau_{acc}$, then the weak-source limit in the sensitivity of a synthesis image of a single polarization is \begin{equation}\label{eq:sens}  \Delta I_m = {\frac{1}{\eta_s }}{\frac{T_{sys}}{\sqrt{2 }}{\frac{SEFD}{\sqrt{2  \Delta \nu \tau_{acc}}}} \end{equation}  in units of Janskys per synthesized beam area.   \subsubsection{Minimize System Temperature} SEFD}  \subsubsection{Maximize System Efficiency}  \begin{equation}\label{eq:system_efficiency}  \eta_s = {\frac{1}{\eta_s }}{\frac{T_{sys}}{\sqrt{2 \Delta \nu \tau_{acc}}}}   \end{equation}  \subsection{Minimize Operations Costs}  \subsubsection{Minimize Maintenance Costs}  \subsubsection{Minimize Calibration Costs}
