In this master's thesis, the minimal dark matter models with radiativeneutrino masses introduced in arXiv:1308.3655 are examined both in general and,using the model T1-3-B ($\alpha = 0$) as a representative, in more detail. Inthe process, it is both shown how such models are built and a numericalanalysis tool chain is established, automating as many steps as possible fromthe very beginning (deriving the Lagrangian from a given field content) to thevery end (calculating observables such as the dark matter relic density, thedirect detection cross section and the neutrino masses and mixing matrices).  As an important result in laying out the mathematical groundwork, aconvention for representations of SU(2) is established which, in this form, isnot found in previous works. Another major result is the development of theprogram minimal-lagrangians, whose capabilities are described in the thesis. Itis of great use both for the construction of Lagrangians for new models as welltheir verification or quick surveys. minimal-lagrangians can be applied to anymodel within the class it is designed to handle, extending its utility farbeyond a one-time result that is only obtained for a single model.  Finally, the first steps in the analysis of the model T1-3-B ($\alpha = 0$)are taken. It is shown that the model can reproduce both the singlet-doubletfermion dark matter model and the inert triplet model in the appropriatelimits. Moreover, the neutrino mass matrix is found and it is demonstrated thatthe model can accommodate current constraints on the neutrino masses. Lastly,the behavior of the dark matter relic density as it depends on the parameterresponsible for the generation of neutrino masses is investigated.  Further in-depth study of the model T1-3-B ($\alpha = 0$) was performed in aseparate publication (arXiv:1812.11133).
