Determinación del riesgo operacional en la línea aérea de contacto del ferrocarril

Abstract

This paper proposes a methodology to determine

the operational risk in a highly complex and

geographically distributed system such as the

overhead contact line of a railway network. This

operational risk refers to the different issues

that may lead to undesirable effects in the

operation of the system ant it is obtained by

means of an index for each of the areas in which

the system is divided taking into account data

such as such as the number of faults in the area,

unavailability of the area, age of the installation

or differences among the actual installation and

the ideal one. All these factors are processed

with the appropriate statistical techniques and

combined through a multivariate technique to

build an index to be used for decision making

in the allocation of investments in each of the

areas in the network with the aim of increasing

the availability of the network.
