general efficiency value of the DMUs. The paper makes four contributions to the literature: (1) we take into consideration the … to deteriorate the efficiency score of the DMUs after input and/or output reduction; (3) we develop a common set of … models; (4) we extend a new approach to optimize the inputs and/or outputs contraction such that the efficiency of all DMUs …

Frontier-based performance analysis models for supply chain management; state of the art and research directions

AGRELL, Per; HATAMI-MARBINI, Adel - Center for Operations Research and Econometrics (CORE), … - 2011

Effective supply chain management relies on information integration and implementation of best practice techniques across the chain. Supply chains are examples of complex multi-stage systems with temporal and causal interrelations, operating multi-input and multi-output production and services...

Capacity utilisation and profitability: a decomposition of short run profit efficiency

COELLI, Tim; GRIFELL-TATJE, Emili; PERELMAN, Sergio - Center for Operations Research and Econometrics (CORE), … - 2001

The principal aim of this paper is to measure the amount by which the profit of a multi-input, multi-output firm deviates from maximum short-run profit, and then to decompose this profit gap into components that are of practical use to managers. In particular, our interest is in the measurement...

What do normative indices of multidimensional inequality really measure?

BOSMANS, Kristof; DECANCQ, Koen; OOGHE, Erwin - Center for Operations Research and Econometrics (CORE), … - 2013

We argue that normative indices of multidimensional inequality do not only measure a distribution’s extent of inequity (i.e., the gaps between the better-off and the worse-off), but also its extent of inefficiency (i.e., the non-realized mutually beneficial exchanges of goods). We provide a...

Fair allocation of disputed properties

JU, Biung-Ghi; MORENO-TERNERO, Juan - Center for Operations Research and Econometrics (CORE), … - 2014

We model problems of allocating disputed properties as generalized exchange economies in which agents have preferences and claims over multiple goods, and the social endowment of each good may not be sufficient to satisfy all individual claims. In this context, we investigate procedural and...

Stable and efficient coalitional networks

CAULIER, Jean-François; MAULEON, Ana; … - Center for Operations Research and Econometrics (CORE), … - 2011

We develop a theoretical framework that allows us to study which bilateral links and coalition structures are going to emerge at equilibrium. We define the notion of coalitional network to represent a network and a coalition structure, where the network specifies the nature of the relationship...
