Abstract
Maintenance is the possibility that maintenance conditions can be implemented in a certain period of time by using certain methods and resources. The importance of the level of maintenance of railway optical communication transmission networks and its repair and optimization (NET) is due to the need to maintain railway safety and prevent rail accidents. Today, the safe movement of trains is not possible without telecommunication networks. The interruption of optical transmission networks leads to the blocking of railway lines, and the blocking of the line leads to the reduction of traffic and productivity, damage to the rail network, and sometimes the occurrence of irreparable accidents in the railways. Also, the disconnection and failure of telecommunication transmission networks leads to the interruption of all train control telecommunication services, because all train control services are based on telecommunication networks. In the railway telecommunication department of J.A., as well as the railway infrastructure, unlike the maintenance and repair system based on reliability, the maintenance is basically done when the devices are out of service, which in addition to imposing heavy additional costs on the railways, causes It reduces productivity and increases the number of breakdowns. Therefore, the current research tries to provide a new model for increasing the level of maintainability by evaluating the current network capability of the railway telecommunication transmission system, which will lead to increasing productivity, safety and reducing the time intervals of blocking the railway network. The case study implemented in this research is Hormozgan railway area.
