In this paper, we introduce the notion of multicriteria-based directional distance determination for estimating the efficiency of decision units under different (and sometimes conflicting) interests and objectives. Different objectives are interpreted as different dimensions of a production system. Multidimensional industries, such as the Higher Education system, usually have clear preference structures and value judgments over teaching, research and service (outreach), leading to ranking differences for countries and organizations based on policy perspectives, production compensations, substitutions or complementation. We develop this framework based on the non-compensatory reasoning of outranking multicriteria methods to determine the most practical directional vector for the output expansion of Higher Education and support a multidimensional efficiency measurement. The numerical application using panel data illustrates policy-directed European countries based on the three dimensions of higher education. A similar understanding can be extended for determining directional efficiency for service units based on other multicriteria methods and heuristics.
