The \(\mathcal{KRA }\) Model

  • Lorenza Saitta
  • Jean-Daniel Zucker


In this chapter the ideas introduced in the previous chapters are formalized in the \(\mathcal{KRA }\) model, which takes into account a problem to be solved and the observations and theory necessary to solve it. Both observations and theory can be expressed at several levels of detail. The model describes how this change of resolution can be achieved. The model is not intended to cover all uses of abstraction, but it is rather targeted toward problems where observations are an important part of the solution process.
