据我们所知，到目前为止，文献中提出的所有网络DEA模型都隐含或明确地假设由网络（系统）组成的所有实体都由单个所有者拥有，即，一个集中的系统。因此，这些模型不适用于实际中的各种分布式和混合系统的性能评估。因此，本研究的目的是显示在构建有效的网络DEA模型时，考虑网络（系统）的所有权结构的重要性，并相应地开发了三个所有权指定（集中式，分布式和混合）的网络DEA模型的输入和输出导向。一个数值例子被用来验证网络DEA方法和应用程序中的实体，从而网络的所有权的关键重要性。
To our knowledge, all network DEA models proposed in the literature so far either implicitly or explicitly assume that all entities comprised of a network (system) are owned by a single owner, i.e., a centralized system. As a result, those models are not applicable to performance evaluation for a wide variety of distributed and hybrid systems in practice. Therefore, this study aims to show the importance of taking into account the ownership structure of networks (systems) in constructing effective network DEA models, and accordingly develops three ownership-specified (centralized, distributed and hybrid) network DEA models in terms of both input- and output-orientation. A numerical example is used to validate the critical importance of the ownership with entities and thus networks in both network DEA methodologies and applications.
