As the core resource of an enterprise, enterprise assets are related to the stable operation and long-term development of the enterprise. However, there are also various risks in operation and management, which may cause impact and losses to the enterprise. This article aims to analyze the risks of enterprise asset management and its management and control strategies. This article provides an in-depth analysis of the risks that an enterprise may encounter during its operation, and provides countermeasures to optimize the shortcomings of the enterprise from all aspects. Enterprise prevention and control must first have a reasonable internal structure, a system for monitoring risks, asset management and monitoring throughout the entire enterprise life cycle, and a balance of enterprise assets.

“…This, in turn, would make it possible to manage the level of vulnerability or risks in the system, while considering the costs and benefits of different asset management strategies and resource allocations. Similar approaches have been successfully adopted globally for managing other transport infrastructures such as roads (Qiao, Dawson, Parry, & Flintsch, 2015) and railways (Sasidharan, Burrow, & Ghataora, 2020;Sasidharan & Torbaghan, 2020).…”

“…Risk assessment techniques such as Monte Carlo simulations, Bayesian, Fuzzy logic and Petri nets are recommended to deal with such uncertainties (Rama & Andrews, 2016;Sasidharan & Torbaghan, 2020;Zhang & Wang, 2014). Majority of these techniques use historical data and probability judgements, and conclusions on the acceptability of the solutions are often made directly based on derived probabilities and confidence levels.…”

Scour is one of the main causes of bridge failures resulting in significant macroeconomic impacts, often beyond the direct costs of infrastructure damage. Given the pressure to increase the resilience of transport networks, ageing bridge infrastructure, constrained budgets, variable knowledge of asset conditions and limited data, mixed ownership and operation of bridges, and concerns about the risks of climate change, there is a need to implement cost-effective monitoring and maintenance strategies. To this end, this study aims to set the scene for a risk-informed approach for tackling bridge scour, while considering the socioeconomic impacts of disruptions due to bridge failures or closures. This study reviews the current practices in predicting, monitoring and managing bridge scour. It discusses the development of a risk-informed approach to aid the whole-life appraisal of bridges while considering the direct and indirect costs associated with bridge failure or closures. The approach provides a rational means to enable asset managers to evaluate the factors that affect bridge failure risk, select and prioritise appropriate mitigation measures, thereby improving the allocation of scarce monitoring and maintenance resources.

“…The risk assessment of the functional safety [42][43][44][45][46] of any engineering object is associated with the definition of reliability [47][48][49], availability, maintainability, and safety (RAMS) [50,51]. It determines the suitability of objects to perform their functions safely (with defined risk levels at all stages of the life cycle) [25,52,53] and efficiently (with a certain level of costs) under specific operating conditions [54][55][56][57].…”

The ability to assess the risks of the functional safety of railway tracks allows harmonizing characteristics of track elements under certain operating conditions under certain maintenance for the efficient use of the track structure throughout its life cycle. The concept of detailing conditions of the interaction of the rolling stock and railway track was used for the productive solution of tasks of infrastructure functional safety assessment. The paper formed an approach to the analytical solution of determination problems of deformability parameters over time using the elastic waves theory. The formation method of interconnections between the technical and economic aspects of the operation of railway infrastructure was proposed. The criteria of deformability work and intensity of use were utilized for the effective use of the track structure through its life cycle. The results of calculations are presented to assess changes in the deformability behaviour of the track elements and structure when the force and speed parameters of the operating conditions change, as well as the algorithm of the method for estimating the operation deformability of the railway track. Thus, the proposed approach can be adapted to optimize objects by railway functional safety assessment at the stage of object operation simulation.
