“…In modelling the correct level of personally acceptable level of risk, the trend is to look for a balance between the cost for safety and the benefit for human life extension (Streicher et al, 2008). Similarly, Vrijling et al (1998) demonstrated that the observation of accident statistics has shown statistical stability in pattern over the years and approximately equal, especially in western countries thereby indicating a consistent pattern of preferences.…”

In this work, the probabilistic methods have been used to produce a methodology capable to estimate the acceptable level of risk in a cost-benefit framework. The benefits and the costs are weighed against associated risks to aid the decision making process on risk acceptance, from both the individual and societal perspective. Thereafter, acceptable individual and societal risk levels are defined based on historical trend of non-voluntary deaths and overall national fatalities. An example is used to explore the practical application of the method to critical infrastructures such as petroleum pipelines. The results show that the cost-benefit risk framework provides a safety standard that is acceptable from both individual and societal perspectives. and MBA (Energy) from University of Oklahoma, USA.

“…Moreover, the concept of sustainability extends to engineering infrastructures and has implications for improving the recycling of building materials [6] and minimizing water, air, and land pollution [1]. Because infrastructure is traditionally financed by public governments, economic sustainability has been an increasing demand from society in recent years [7,8]. However, the field of infrastructure engineering frequently does not benefit from the developments in environmental management because many worldwide administrations keep archives of documents in an inefficient paper format.…”

Engineering infrastructures require regular maintenance and/or repair activities that have important social, environmental, and economic impacts. Despite their growing importance, few studies have focused on fully integrated analyses. This work presents a general methodological approach to design databases of engineering maintenance activities for their assessment. This methodology was applied to the case of dredging projects in the ports managed by the Andalusian Regional Government (Spain). The resulting database contains 87 fields of information obtained from the analysis of 70 activities performed between 1993 and 2015. This database is free, public, and available to the scientific community, and it was implemented in PostgreSQL using the PostGIS extension for spatial data; therefore, it can be integrated in a GIS. The assessment of deviations from the initial projects and the comparison between locations enhanced our methodology, which represents a valuable tool not only for scientists and managers to improve the decision-making process when planning future strategies, but also to evaluate the environmental impacts.

“…More elaborate models have been proposed to include the randomness of progressive deterioration (Streicher et al, 2008;Klutke and Yang, 2002). In general these can be classifi ed into two broad categories, the random variable (RV) model and the stochastic process model.…”
