A review over risk evaluation, identification & management in different railway projects
Meysam Shokati Azar1 Mahdi Soleymanifar2
Abstract :
A community s infrastructure refers to the facilities, services, and assets that are necessary for its operation. Assets, facilities, and infrastructure with high fixed costs (long economic lives) have significant impacts on economic development and public health, as well as physical assets that can provide long-term services and benefits. Since railway projects are long-term in construction, require huge investments and have many risk factors during construction and operation. Derailment, fire, landslides, falls from heights, vehicle collisions, electric shocks at stations, and floods, earthquakes, storms, corrosion are all potential issues in railway operations, as well as when building the structures themselves. Conditions on land unexpectedly include late payments to contractors, tunnel drilling rig diverted, collision with underground infrastructure, and lack of funds. In research studies, the most critical risks during construction are unexpected ground conditions, delay payments to contractors, diversion of the tunnel drilling rig initially, derailment and collisions of vehicles, and floods. The level of risk management needs to be improved as well as the identification, evaluation, and estimation of risks related to assets in order to protect assets and promote projects and economic development. Due to the different methods for assessing human error, technical difficulties and natural phenomena, most of the methods were based on human error. As there is little information available about railway accidents and events and if there is, the data has high uncertainties, the fuzzy logic method based on FAHP hierarchical analysis, or the AHP method is recommended in such cases. A combined approach of risk management and value engineering can be effective, since the principles of risk management have an increasing focus on costs to deal with threats, and can also be viewed as one of the economic methods. So, the best method for responding to threats is selected from preventive response measures.
