So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...

  For efficiency evaluation of some of the Decision Making Units that have uncertain information, Rough Data Envelopment Analysis technique is used, which is derived from rough set theorem and Data Envelopment Analysis (DEA). In some situations rough data alter nonradially. To this end, this paper proposes additive rough–DEA model and illustrates the proposed model by a numerical example.

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...

Data Envelopment Analysis is a technique based on linear programming methods to construct surface or non parametric boundary over the data. This boundary is used to evaluate proportional efficiency. In this paper, a mixed model was proposed based on Stochastic Data Envelopment Analysis (SDEA) and Principal Component Analysis (PCA) for predicting the similar units' efficiencies in an organizatio...
