An Overview of the Reliability Analysis Methods of Tunneling Equipment

Abstract

The absolute prevention of damage occurrence is not possible, thus reducing the probability of failure in a system and its impact is very important regarding the operation of a whole system. A failure in a system or in its subsystems makes negative results such as the stop in the production process, rising labor costs, and increasing the cost of maintenance. Reliability, in recent years, is mentioned as one of the most significant aspects of the quality of goods and services. In the past, reliability concerned sensitive and complex industries such as military, nuclear, and aerospace where the lack of their reliability could cause irreparable damage to the entire system. However, today it has become a universal concern. Tunneling equipment has grown in size and complexity and therefore, lack of reliability may cause massive costs to this equipment. Therefore, reliability determination in order to identify the components and subsystems with low reliability is essential. The aim of this study is to review the methods of tunneling equipment reliability analysis including statistical analysis, failure mode and effects analysis, Markov and fault tree methods. In addition, previous available research on the reliability analysis of tunneling equipment is presented.

Optimization maintenance performance level through collaboration of overall equipment effectiveness and machine reliability

“…with: In the past, MR was associated with sensitive and complex industries such as military, nuclear, and aerospace. Until now, MR has become a universal concern as one of the most important aspects of the quality of goods and services [38]. One way to maintain reliability is to perform machine or system maintenance [3], [39].…”

Reliability analysis of the compressed air supplying system in underground mines

“…Nowadays, Markov chains modeling has been widely used for the system reliability and availability assessment in different fields of mining operations such as the reliability estimation of the auxiliary ventilation systems in the construction of long tunnels 14 , the selection of the crusher location 15 , production performance optimization of Load–Haul–Dump machines 16 , reliability analysis of mining drilling operation 17 , 18 , reliability, maintainability, and availability of tunnel boring machines 19 , 20 , and reliability, availability, and maintainability analysis of shovel and dump trucks in open pit mines 21 .…”

Risk Control for Synchronizing a New Economic Model

“…Reliability is defined as the ability of an item to start and continue a predefined process under certain operating conditions, whereas risk refers to the potential loss that arises from exposure to a hazard. As it is shown in [1][2][3][4], the risk value can be computed based on the reliability value.…”
