A Non-radial rough DEA model
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.
متن کاملA NON-RADIAL ROUGH DEA MODEL
There are situations that Decision Making Units (DMU’s) have uncertain information and their inputs and outputs cannot alter redially. To this end, this paper combines the rough set theorem (RST) and Data Envelopment Analysis (DEA) and proposes a non-redial Rough-DEA (RDEA) model so called additive rough-DEA model and illustrates the proposed model by a numerical example.
متن کاملSafety at Level Crossings
Every year, more than 400 people are killed in over 1200 accidents at road-rail level crossings in the European Union. Together with tunnels and specific road black spots, level crossings (LC) have been identified as being a particular weak point in road infrastructure, seriously jeopardizing road safety. Safety at LC is a single part of a wider picture of transport safety within the whole tran...
متن کاملMeasuring driver responses at railway level crossings.
Railway level crossings are amongst the most complex of road safety control systems, due to the conflicts between road vehicles and rail infrastructure, trains and train operations. Driver behaviour at railway crossings is the major collision factor. The main objective of the present paper was to evaluate the existing conventional warning devices in relation to driver behaviour. The common conv...
متن کاملNetwork DEA: A Modified Non-radial Approach
DEA is a non-parametric and linear programming based technique that attempts to maximize a decision making unit’s (DMUs) relative efficiency, expressed as a ratio of outputs to inputs, by comparing a particular unit’s efficiency with the performance of a group of similar DMUs that are delivering the same service. The traditional DEA models treat DMUs as black boxes whose internal structure is i...
