We develop two mathematical modeling-based approaches that incorporate these concerns in such problems. The first formulation aggregates the multidimensional efficiency and equality (equitability) concerns in a biobjective model. The second formulation defines an objective function for each benefit, which maximizes the total social welfare obtained from that specific benefit distribution; this results in an n-objective model, where n is the number of benefits. We illustrate and compare these approaches on an example public service provision problem.EnglishEqualityEquitabilityFairnessPublic service provisionPublic educationKnapsack problemEquityEpsilon constraint algorithmBi-objective optimizationArticle10.1016/j.seps.2021.1011761873-6041
