This paper presents a literature review of efficiency analysis in transportation systems (TS). It builds bibliometric published data-envelopment and, for the first time, stochastic frontier publications TS. The retrieved were separated into five groups: highway/road transportation, air maritime/port railway and urban/bus transportation. 135 data-envelopment-analysis rail-related surveyed to ass...

China’s raw milk production is confronted with problems such as high costs, stringent environmental constraints, weak industrial interest linkages, etc. The extensive and inefficient operation mode seriously restricts the further development of dairy industry. How to increase efficiency realize transition from “a country production” high-efficiency has become key developing In order explore upg...

The changing economic conditions have challenged many organizations to search for more efficient and effective ways to manage their supply chain. During recent years supplier selection decisions have received considerable attention in the supply chain management (SCM) literature. There are four major decisions that are related to the supplier selection process: what product or services to order...

the present study is an attempt toward evaluating the performance of portfolios and asset selectionusing cross-efficiency evaluation. cross-efficiency evaluation is an effective way of ranking decisionmaking units (dmus) in data envelopment analysis (dea). conventional dea models assume nonnegativevalues for inputs and outputs. however, we know that unlike return and skewness, varianceis the on...
