Abstract: This paper provides a review of the evolution, development and future research directions on the use of weights restrictions and value judgements in Data Envelopment Analysis. The paper argues that the incorporation of value judgements in DEA was motivated by applications of the method in real life organisations. The application driven development of the methods has led to a number of different approaches in the literature which have inevitably different uses and interpretations. The paper concentrates on the … Show more

“…The weight restrictions are helpful in practical applications since their use can significantly improve the efficiency discrimination of DEA models (Allen et al, 1997). Thompson, Singleton Jr, Thrall, and Smith (1986) were among the first to proposed weights restriction to differentiate between efficient units, while Dyson and Thanassoulis (1988), considered that restricting weights is important to avoid ignoring of some inputs or outputs.…”

“…Different approaches to restricting weights are typically proposed as a possible remedy to this issue. One of the first and most important papers on weight restrictions in DEA was written by Allen, Athanassopoulos, Dyson, and Thanassoulis (1997). This paper offered a comprehensive overview of the development of weight restrictions in DEA and provided guidelines for future research in that area.…”

“…No entanto, os modelos de suavização existentes até agora, que tivessem praticidade de uso, eram apenas para o modelo BCC. Ora, o modelo BCC apresenta eficiências negativas implícitas, que aparecem em situações como projeções não radiais (Gomes Júnior et al, 2013) e avaliação cruzada , 2013, o que faz com que apenas em raras ocasiões possa ser usado em modelos de avaliação cruzada. Assim, o desenvolvimento de um modelo de suavização para DEA-CCR passa a permitir o uso de pesos calculados por este método em modelos de avaliação cruzada.…”

“…Allen et al (1997) Thompson et al (1990). Em (3) apresenta-se a formulação genérica do modelo BCC com as restrições ARI impostas aos outputs, onde α i e β i são constantes especificadas pelo decisor e que, após uma conveniente normalização, refletem os julgamentos de valor sobre a importância relativa entre os outputs i e i + 1.…”
