Super-efficiency based on a modified directional distance function

Chen, Yao; Du, Juan; Huo, Jiazhen - In: Omega 41 (2013) 3, pp. 621-625

The problem of infeasibility arises in conventional radial super-efficiency data envelopment analysis (DEA) models … developed based on a directional distance function. Although this N–L super-efficiency model does not suffer infeasibility …-efficiency model successfully addresses the infeasibility issues occurring either in conventional VRS models or the N–L super …

Additive super-efficiency in integer-valued data envelopment analysis

Du, Juan; Chen, Chien-Ming; Chen, Yao; Cook, Wade D.; … - In: European Journal of Operational Research 218 (2012) 1, pp. 186-192

Conventional data envelopment analysis (DEA) methods assume that input and output variables are continuous. However, in many real managerial cases, some inputs and/or outputs can only take integer values. Simply rounding the performance targets to the nearest integers can lead to misleading...

DEA Models for Parallel Systems: Game-Theoretic Approaches

Du, Juan; Zhu, Joe; Cook, Wade D.; Huo, Jiazhen - In: Asia-Pacific Journal of Operational Research (APJOR) 32 (2015) 02, pp. 1550008-1

In many settings, systems are composed of a group of independent sub-units. Each sub-unit produces the same set of outputs by consuming the same set of inputs. Conventional data envelopment analysis (DEA) views such a system as a "black-box", and uses the sum of the respective inputs and outputs...

Fixed cost and resource allocation based on DEA cross-efficiency

Du, Juan; Cook, Wade D.; Liang, Liang; Zhu, Joe - In: European Journal of Operational Research 235 (2014) 1, pp. 206-214

In many managerial applications, situations frequently occur when a fixed cost is used in constructing the common platform of an organization, and needs to be shared by all related entities, or decision making units (DMUs). It is of vital importance to allocate such a cost across DMUs where...
