This second edition systematically presents the underlying theory, model development, and applications of network Data Envelopment Analysis (DEA). It discusses the models used to measure the efficiency of systems in specific network structures and introduces readers to the latest applications. It demonstrates how the “network DEA” approach helps identify and manage the specific components that cause inefficiencies in the overall system. The existing models for measuring the efficiency of systems in specific network structures are also discussed, and the relationships between system efficiency and component efficiency are explored. Moreover, the book provides an advanced exposition on per...

This is the first full-length institutional study of the organization and functions of the Imperial Household Department under Ch'ing rule. That department constituted the emperor's 'personal bureaucracy.' In tracing the complex structure of this organization, Preston Torbert has avoided an exhaustive listing of nominal offices and their prescribed duties; instead, he has described the distinctive 'social groups' that made up the departments total personnel-the bondservants, the eunuchs, and the palace maids.

Relations between Inner Asian nomads and Chinese are a continuous theme throughout Chinese history. By investigating the formation of nomadic cultures, by analyzing the evolution of patterns of interaction along China's frontiers, and by exploring how this interaction was recorded in historiography, this looks at the origins of the cultural and political tensions between these two civilizations through the first millennium BC. The main purpose of the book is to analyze ethnic, cultural, and political frontiers between nomads and Chinese in the historical contexts that led to their formation, and to look at cultural perceptions of 'others' as a function of the same historical process. Based on both archaeological and textual sources, this 2002 book also introduces a new methodological approach to Chinese frontier history, which combines extensive factual data with a careful scrutiny of the motives, methods, and general conception of history that informed the Chinese historian Ssu-ma Ch'ien.
This handbook serves as a complement to the Handbook on Data Envelopment Analysis (eds, W.W. Cooper, L.M. Seiford and J, Zhu, 2011, Springer) in an effort to extend the frontier of DEA research. It provides a comprehensive source for the state-of-the art DEA modeling on internal structures and network DEA. Chapter 1 provides a survey on two-stage network performance decomposition and modeling techniques. Chapter 2 discusses the pitfalls in network DEA modeling. Chapter 3 discusses efficiency decompositions in network DEA under three types of structures, namely series, parallel and dynamic. Chapter 4 studies the determination of the network DEA frontier. In chapter 5 additive efficiency decom...
