The state of gauge geometry is the basis for safe and uninterrupted train operations under mixed traffic conditions, as well in sections where trains with increased weight length, including wagons an axle load, are handled. When passing such trains, deteriorates. This leads to labour costs track maintenance, which also caused by climatic features. Under it important carry out effective maintena...

Data envelopment analysis (DEA) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (DMUs) where multiple inputs and outputs exist. In the conventional applications of DEA, the data are considered as specific numerical values with explicit designation of being an input or output. However, the observed values of the data are sometimes imprec...

Efficiency evaluation of units has been of interest since many years in different domains such as management, economy, business, banking, and many others. Data envelopment analysis is one of the popular operations research methods for measuring the relative efficiency of units, which use multiple inputs to produce multiple outputs. As we know, universities play a key role in many aspects of a c...
