Abstract
Decision-making surrounding asset renewal is essential for the efficient use of renewal resources and safe operation of urban rail transit. In this study, major problems in the current management of urban rail industries in countries with the same problems as those in China were analysed, and in response, a renewal management framework based on service life estimation was proposed to provide adequate decision-making support for urban rail transit assets. In this framework, the cumulative failure frequency of an asset is used to indicate its health condition, and considering the uncertainties and heterogeneities in the deterioration process of assets, a Poisson–Weibull process model-based methodology was developed to estimate the service and residual lives of each asset, which are then employed in analysing its renewal demand and renewal period. Finally, the model is validated through an empirical study of rail renewal in the Beijing Metro. Our evaluation demonstrates that the proposed framework can estimate each asset’s service life accurately and can be used by asset management personnel to establish reasonable renewal plans and provide decision-making support for a scientifically informed resource allocation, thus mitigating major problems in current management practices.

Summary
Urban rail transit is one of the most effective ways of meeting the public’s travel needs and alleviating urban traffic congestion, and governments in many countries and regions have made significant investments to develop it. In many cities, such as London, Paris, New York, and Tokyo, of developed countries, urban rail transit has been operating for many years. Asset renewal management in urban rail industries In many countries, such as China, design working life and health condition are the 2 major bases of managing asset renewal in urban rail industries (Scarf et al 2007; Scarf, Hartman 2008; DB 11/T718:2016):.
