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...

This paper addresses issue of sensitivity of efficiency classification of variable returns to scale (VRS) technology for enhancing the credibility of data envelopment analysis (DEA) results in practical applications when an additional decision making unit (DMU) needs to be added to the set being considered. It also develops a structured approach to assisting practitioners in making an appropria...

Background: In this study, the effect of wastewater produced by pistachio processing in processing terminals on wastewater treatment plants with activated sludge process was investigated. Methods: The pilot of activated sludge was constructed at the laboratory scale similar to wastewater treatment plant in Kerman and it was investigated in different ratios of the wastewater of pistachio proces...

Efficiency Analysis for Multicomponent Production Processes Conventional models concerned with efficiency analysis of organizations typically consider a single production process, or technology, in which all inputs are used the outputs. This approach does not account well situations involved several component processes whose and outputs may be shared by different processes. The main difficulty ...
