Projection and bidirectional projection measures of single-valued neutrosophic sets and their decision-making method for mechanical design schemes

Projection measure is one of important tools for handling decision-making
problems. First, the paper proposes projection and bidirectional projection
measures between single-valued neutrosophic sets, and then the comparison
of numerical examples shows that the bidirectional projection measure is
superior to the general projection measure in measuring closeness degree
between two vectors.
