Na metodologia DEA (Data Envelopment Analysis) existem dois importantes tipos de modelos para avaliar a eficiência relativa de um conjunto de DMUs (Decision Making Units): os modelos radiais e os modelos não radiais. Nos primeiros, a eficiência é obtida através da redução (expansão) proporcional e comum dos inputs (outputs) mantendo os outputs (inputs). Nos segundos, a eficiência é obtida usando os desvios associados aos excessos de input e aos défices de output, que são ignorados nos modelos radiais.
A presente dissertação destina-se a apresentar um estudo sobre esses dois tipos de modelos da metodologia DEA e sobre a aplicação de alguns desses modelos à avaliação do impacto, em termos de eficiência, decorrente da reorganização administrativa das freguesias do concelho de Lisboa, ocorrida no ano de 2013, que resultou numa redução considerável do número de freguesias de 53 para 24.
In the DEA (Data Envelopment Analysis) methodology there are two important types of models for evaluating the relative efficiency of a set of DMUs (Decision Making Units): the radial models and the non-radial models. In the former, efficiency is obtained by proportionally and commonly reducing (expanding) inputs (outputs) while maintaining outputs (inputs). In the latter, efficiency is obtained using the deviations associated with input excesses and output shortfalls, which are ignored in radial models. This dissertation aims to present a study on these two types of models of the DEA methodology and on the application of some models to the evaluation of the impact, in terms of efficiency, resulting from the administrative reorganization of the parishes in the municipality of Lisbon, which took place in 2013, resulting in a considerable reduction in the number of parishes from 53 to 24.
