Economic Decision Theory

AbstractThis paper examines a class of premium functionals which are (i) comonotonic additive and (ii) stochastic dominance preservative. The representation for this class is a transformation of the decumulative distribution function. It has close connections with the recent developments in economic decision theory and non-additive measure theory. Among a few elementary members of this class, the proportional hazard transform seems to stand out as being most plausible for actuaries.

Economic Decision Theory

About 200 marine platforms are installed in the Mexican sector of the Gulf of Mexico so that maintenance and inspection schedules play an important role to avoid excessive structural deterioration of the oil facilities and at the same time to keep the facilities within acceptable safety margins. Large costs associated with inspection and repair actions moved managers towards the application of an optimal strategy in order to minimize inspection expenses. For these purposes, it is necessary to consider deterioration process such as fatigue crack growth under the influence of uncertain wave loading which is the dominant force while effort is focused on maintaining structural integrity and safe production. This paper presents an optimal inspection methodology for offshore structures based on an economic decision theory, bearing in mind that large costs are associated with structural failure and extensive inspection and repairs. A system failure analysis of a given sub set of the critical structural components is included as well as a mathematical framework for the assessment of failure and repair cost associated.

Civil aviation faces increased cybersecurity threats due to hyperconnectivity and the lack of standardized frameworks and cybersecurity defenses. Educating the civil aviation workforce is one method to enhance cyber defense against cyber-attacks. Educating the workforce will lead to initiatives and strategies to combat cyber-attacks. Private and public entities need to remain aggressive in developing cyber defense strategies to keep pace with the increasing vulnerabilities of hyperconnectivity. Areas that require immediate attention to safeguard against cybersecurity threats in civil aviation are: 1) Eliminating supply risks, 2) Upgrading legacy systems, 3) Mitigating technological aftereffects, 4) Increasing cybersecurity awareness, 5) Developing cybersecurity workforce, 6) Managing hyperconnectivity, and 7) Leveraging international entities. To safeguard civil aviation infrastructure from cybersecurity threats require assertive, coordinated, and effective strategies and capabilities to defend the network.
