In this paper, we introduce an inclusion measure for interval neutrosophic sets, which is one of information measures of interval neutrosophic theory. For this purpose, we first give a system of axioms for inclusion measure of interval neutrosophic sets. Using the concept of distance measure, we develop a simple inclusion measure for ranking the interval neutrosophic sets. Finally, a multi attribute decision making problem is presented to show effectiveness of proposed inclusion measure, and
