To enhance the availability of superstructure optimization as a tool in process design for industries as well as science this work presents a fully Open sUperstrucTure moDeling and OptimizatiOn fRamework (OUTDOOR). This framework is written in Python using object-oriented programming in combination with algebraic modeling utilizing the PYOMO modeling language. In addition, an Excel-based data preparation tool, called Excel-Wrapper is presented. It provides an intuitive way to prepare process data and generate superstructures, which are ready-made for solving using open-source as well as commercial optimization solvers.
