Risk-based bridge asset management
… developed DSS introduces a streamlined bridge risk assessment methodology that leverages structural reliability and advanced probabilistic models to perform risk projections, accounting for the degradation in both the short and long-term. The methodology is based on the general definition of …

Flexible risk-based portfolio optimisation
… is to present and test a general framework for risk-based investing. It permits various risk-based portfolios such as the global minimum variance, equal risk contribution and equal weight portfolios. The framework also allows for different estimation techniques to be used in finding the …

Risk based control in uncertain environments
… control decisions in real-time. Using a map of risk to the robot's state, a risk gradient controller can be created to find paths back to safety from anywhere in the robot's reachable space. Despite generating a variety of complex and dynamic behaviors, this method suffers from sensitivity to …

Risk based analogy for e-business estimation
… evolution of e-business and as new trends on web based applications develop at a very fast pace, projects to implement new and adapt existing e-business systems are becoming more complex in their structure. At the same time, organizations involved as stakeholders are becoming more demanding in the …

Dopaminergic modulation of risk-based decision making
… with larger rewards. However, the role of DA in risk-based decision making remains relatively unexplored. The present study investigated how systemic manipulations of DA transmission affect risky choice assessed with a probabilistic discounting task. Over discrete trials, rats between two levers; …

Privacy-Aware Risk-Based Access Control Systems
… this potential, while controlling the privacy risk, it is necessary to develop novel data sharing and access control mechanisms able to support risk-based decision making and weigh the advantages of information against privacy considerations. To achieve this, access control decisions must be …

A risk-based fire and rescue management system
This PhD focuses on developing a risk-based fire and rescue model for dwelling fires which importantly, is where most fire deaths occur each year. There are a vast number of variables to consider when modelling dwellings, for example variations will arise in terms of geographical location, fire …

Risk-based framework for ballast water safety management
… of recipient regions and port states. The risks associated with the discharged NIS are uncertain and difficult to assess due to the stochastic nature of species assemblages and dispersal mechanism. The safest control measure advocated by the IMO is the conduct of ballast water exchange at …

A risk-based maintenance methodology of industrial systems
Maintenance is an essential task that must be carried out in an efficient and effective manner in order to sustain and prolong the physical assets of a company. Maintenance may be defined as any action which has the objective of retaining or restoring an item to a state in which it can perform its …

Risk-based Security Management in Critical Infrastructure Organizations
… defenses insufficient. Therefore, concerns over risks like terrorism, crime, and business revenue loss increasingly impose the need for enhancing and managing security within the boundaries of these systems so that unwanted incidents (e.g., potential intrusions) can still be detected with higher …

Designing for cyber security risk-based decision making.
… cyber security decisions typically follow risk- based analytical approaches where alternative options are put forward based on goals and context, and weighed in accordance to risk severity metrics. These decision making approaches are however difficult to apply in risk situations bounded by …

Risk-Based Game Modelling for Port State Control Inspections
… both qualitative and quantitative. The risk factors influencing the inspection results and the decision-making of port authorities under NIR are identified through the practical inspection records and related literature. The Paris Memorandum of Understanding (MoU) offers the historical …

Optimal risk-based design of bulk water supply systems
Bulk water supply systems generally consist of a source of water, a conveyor (feeder pipe, canal etc.) and a storage facility. Designing bulk water supply systems includes the sizing of these components to ensure a functional system...The study follows the same methods that have been used by …

A Risk Based Approach to Intelligent Transportation Systems Security
… System (ITS) security impact-oriented risk assessment in threefold. • First, I employ a risk-based approach to conduct a threat assessment. This threat assessment performs a qualitative vulnerability-oriented threat analysis. The objective is to scrutinize safety, security, reliability, …

Risk-Based Framework for Focused Assessment of System Dynamics Models
… this research developed a modeling process risk-based framework focused on the objectives of the system dynamics methodology. This approach assists modelers in prioritizing the modeling process risk management requirements — and resources — for a project by employing a modeling process risk …

RISK-BASED FRAMEWORK FOR SAFETY MANAGEMENT OF ONSHORE TANK FARM OPERATIONS
… on environment. To eliminate or minimize the risk of major incident/accidents, as well as minimize the magnitude and severity, it is acutely urgent to uncover and assess all potential hazards, with a view to adopt the best preventive/mitigative policy direction in the management of this …
