Risk Assessment Methodology

The paper presents a risk assessment methodology for operational limit states of submarine outfall projects that considers: the environmental legislative framework, the climate agents acting on the coastline and prediction of the plume long-term behaviour near the coastline. The probability of operational failure or stoppage is assessed enabling decision on project design alternatives.

Risk Assessment Methodology

It is a challenge to prevent an occupational accident in any industrial activities. The aim of this study is to improve the safety and reduce the risk of occupational accidents at shipyard through developing a risk assessment. This paper describes the concept and methodology of risk assessment for occupational safety and its application. The methodology introduces an effective and useful assessment procedure to construct the database based on the past occupational accidents occurred at shipyards. Quantitative methodology is developed to understand the unsafe working conditions and environment at the shipyard by the convenient handheld to collect the data with Information Technology. Some examples of effective hazard countermeasures are suggested and a feasibility study is conducted to improve a walking environment at shipyards.

The aim of this study is to improve safety and reduce the risk of occupational accidents at shipyards by developing a risk assessment methodology using work observation technique. This article describes a concept and methodology of risk assessment for occupational safety and its application. It introduces an effective and useful assessment procedure designed from a database based on the past cases of occupational accidents at shipyards. A quantitative method is developed to understand unsafe working conditions and environment at shipyards. A mobile device is used to collect the work observation data at the shipyard, and some examples of effective hazard measures are suggested. Based on the methodology, a feasibility study was conducted to improve walking safety at a numerical control (NC) cutting process of a shipyard in Japan.

The Brain

Keyhole neurosurgery implies reaching a target area inside the brain through an entry point specified by the neurosurgeon. In order to avoid complications, a risk assessment procedure must be done to establish the minimum risk trajectory from the entry point to the target area. The neurosurgeon establishes the risk values for the brain structure according to the type of intervention. The preset brain structure risk value is used to assess the risk value for each voxel of the brain. This paper proposes an improved risk assessment methodology based on the sum of N maximum risk values for each voxel. Then, risk assessment for a trajectory is done by adding the risk of all voxels that are part of the path. The safest trajectory is defined as the trajectory with the lower risk. Our proposed search trajectory methodology includes a Genetic Algorithm (GA) for finding the safest trajectories. The use of a GA drastically reduces the number of trajectories to analyze, speeding up the planning procedure. The achieved results were qualified by expert neurosurgeons as satisfactory. Our proposed method allows neurosurgeons to calibrate the surgical planning system by allowing them to establish the risk brain structure and the risk value for each structure.

Level Of Risk

The article deals with the main theoretical aspects of risk assessment of industrial enterprises in theshort-and long-term periods. The main features of short-term and long-term risks inherent to industrial enterprises have been determined. Comprehensive risk assessment methodology has been developed based onobtaining coherent assessment of the level of short-term and long-term risks. This methodology can be implemented in the form of an express assessment (simplified risk assessment) and in the form of risk matrix(advanced assessment of risks), depending on the objectives of the assessment, available resources andother constraints. The expediency of using an express assessment is, first of all, in the analysis of dynamicsof the level of risk at the enterprise. By positioning the risk profile of an enterprise in a certain area of thematrix of risks, it is possible to determine the main reserves for reducing the overall level of risk and increasethe effectiveness of risk management. The assessment of the risk level dynamics of activity, obtained in theform of risk vector, also provides significant basis for decision making on risk management.

Risk Assessment Methodology

Abstract As counterfeiting techniques and processes grow in sophistication, the methods needed to detect these parts must keep pace. This has the unfortunate effect of raising the costs associated with managing this risk. In order to ensure that the resources devoted to counterfeit detection are commensurate with the potential effects and likelihood of counterfeit part usage in a particular application, a risk based methodology has been adopted for testing of electrical, electronic, and electromechanical (EEE) parts by the SAE AS6171 set of standards. This paper provides an overview of the risk assessment methodology employed within AS6171 to determine the testing that should be utilized to manage the risk associated with the use of a part. A scenario is constructed as a case study to illustrate how multiple solutions exist to address the risk for a particular situation, and the choice of any specific test plan can be made on the basis of practical considerations, such as cost, time, or the availability of particular test equipment.
