We presented a procedure for multicriteria assignment problems. Assignment to a category is based on the comparison between an action and categories’s boundaries. Boundary is represented by the least typical action that can be included in the category, and is considered as the category’s inclusion threshold. Comparison is executed considering performance on evaluation criteria and calculation of a fuzzy inclusion relation, generalizing preference relations model with concordance and non-discordance concepts as used in ELECTRE methods. An illustrating example is also presented to demonstrate method’s application to assignment problems. The proposed procedure can be applied to a variety of domains, such as production and operations, as well as financial and human resources.
