Abstract

The main purpose is modeling and optimizing sustainable growth of space community in order to guarantee its future development with minimun impact in the environment (social, economic and environmental goals) that surrounded it. Going from imagination of CSR principles and theory to real metrics and its implementation by quantitative analysis. A new substantive programmatic approach in CSR understanding pursuing a global maximum avoiding local ones.
 
Space sector is a key strategic area in mankind development that every government and company all around the world must support. For that reason sustainable principles are even more important in space sector rather than other ones, although in these industries sustainablity is "{\it cutting edge{\it "}} and is more studied than in space one.

It is proposed a set of tools to model, analyze, optimize and check the sustainability of a space project during its lifecycle, such as Goal Programming, Project Sustainable Profile, Risk Analysis, using a PDCA methodology.

{\bf PLAN}

 
\begin{itemize}\item Identify key project variables\end{itemize}
\begin{itemize}\item Define KPIs por those variables (\%)\end{itemize}
\begin{itemize}\item Identify dedicated resorces levelling\end{itemize}
\begin{itemize}\item Identify risks\end{itemize}

{\bf DO}

\begin{itemize}\item Model the project (Function Z to maximize, constraints...)\end{itemize}
\begin{itemize}\item Solve the model (Goal Programing, Multigoal Optimization)\end{itemize}
\begin{itemize}\item Establish the Sustainable Baseline in the Project Sustainable Profile and correspondent lower limit\end{itemize}
\begin{itemize}\item Evaluate and quantify risks (Balance variables in Z function)\end{itemize}

{\bf CHECK}

\begin{itemize}\item Monitor all variables and risks periodically through each corresponden KPI\end{itemize}
\begin{itemize}\item Update Project Sustainable Profile\end{itemize}

{\bf ACT}

\begin{itemize}\item Update level of resources needed to reach foreseen sustainability (increase/decrease)in case any variable is outside sustainability tolerances\end{itemize}

The sustainability function is defined as following: Max Z = \{X economics, X social, X environment\}, where Z is the Sustainable Project Index, and X the variables considered for the project. Those variables are balanced by coefficients coming from risk analysis, prioritizing the more critical ones by forcing a higher level, it means, more dedicated resources. Also a set of constratins, which represent the level of the resources dedicated, must be modeled.

As a result, it is obtained metrics and trends to pursue in accordance with the resources dedicated, and a global sustainbility index (Z value) to clasify and prioritize projects. Trying to support the more sustainable projects, or if it is necessary to support a project due to strategic reasons, provide the necessary resources to reach a minimum sustainable level.

The two major milestones reach with this work are:

\begin{itemize}\item Kick-off point considering sustainability as a decision parameter in space project evaluation and prioritization\end{itemize}
\begin{itemize}\item Triggering the standardization of space sustainable principles and best practices\end{itemize}
