Figure 1: Venn diagram of a DSm hybrid model for a 3D frame.

<p>As another simple example of hybrid DSm model, let&#39;s consider the 3D case with the frame &pound; = f&micro;1; &micro;2; &micro;3g with the model M 6= Mf in which we force all possible conjunctions to be empty, but &micro;1 \ &micro;2. This hybrid DSm model is then represented with the Venn diagram on Fig. 1 (where boundaries of intersection of &micro;1 and &micro;2 are not precisely de&macr;ned if &micro;1 and &micro;2 represent only fuzzy concepts like smallness and tallness by example).</p>
