Cost analyses risk estimates including

Presentation of results Structured format Report results in disaggregated as well as aggregated data. Use International Conference on Harmonisation guidelines, include risk estimates and sub group analysis where appropriate. Reports costs and resource use separately. 

Flood risk management includes the analysis and assessment of risks and the formulation and implementation of risk reduction options. Risk analysis includes hazard as well as vulnerability determination and estimates the integral risk. Risk assessment deals with the evaluation and weighing of costs and benefits to derive a tolerable level of risk, taking risk perception into accoimt. Risk reduction deals with planned and realized measures and instruments supposed to decrease risks before (pre-flood), during the event and after an event (post-flood). Figure 38.1 shows the three tasks included in flood risk management. 

Cost benefit analysis requires a value to be placed upon the costs of improvements suggested or decided upon. These will include the cost of reducing the risk, eliminating the hazard, any capital expenditure needed and any ongoing costs applicable. An estimate of the pay-back period will be needed. Decisions on action to be taken are often based on... 

The project planning forms the basis for the financial planning. An (on-going) cost estimate must be made as the project proceeds. These are the costs for project preparation (including Client s advisors), construction and maintenance costs, operational costs, costs of financing and the costs of risks. These costs must be offset against the expected project income. Such a financial analysis is an important tool to manage the project and is also often required to obtain... 

In his testimony on the rescission of the Adams Rule William Nordhaus gave a critique of NHTSA s benefit-cost analysis and offered an alternative study. His critique covers munerous topics including the estimated cost of passive belts and the value of risk reductions employed. The central issue, however is the projected increase in usage which would accompany passive safety belts. 

The use of cost-benefit analysis plays an important role in the decision-making process for fire protection systems. A cost-benefit analysis sums the expected benefits and is divided by the sum of the expected costs. A challenge often lies in determining what "expected" means and estimating the value of money over the time period the fire protection is in use. In fire protection, the expected benefits can be defined as the difference between the cost of a loss without protection and the cost of a loss with protection. The exported costs include the initial costs of the fire protection as well as any annual testing and maintenance costs. The likelihood of an incident is factored in to obtain residual risk. This residual risk is compared to the benefit to determine what benefit is available each year versus the annualized cost. 

Methods for including the cost of capital in economic analyses have been discussed in Chap. 7. Although the management and stockholders of each company must establish the company s characteristic cost of capital, the simplest approach is to assume that investment of capital is made at a hypothetical cost or rate of return equivalent to the total profit or rate of return over the full expected life of the particular project. This method has the advantage of putting the profitability analysis of all alternative investments on an equal basis, thereby permitting a clear comparison of risk factors. This method is particularly useful for preliminary estimates, but it may need to be refined further to take care of income-tax effects for final evaluation. 

All frameworks are based on the idea that professional analysts estimate risks independently from how assessors, decision-makers or other stakeholders value the risks. This distinction between (scientific, value-free) assessments and value judgments is well articulated by ISO (2002) Risk analysis describes risk whereas risk evaluation broadens the picture to include aspects such as cost-benefit balances, pohtical priorities, potential for conflict resolution and social mobilisation potential. The difficulties in separating facts from values have been discussed extensively in literature, in particular by social scientists, see... 

A mixture of qualitative and quantitative methods was used in this work. These include reliability analysis, eapital investment costs, safety, feasibility and environmental impaet assessment (ElA). Tools used include failure mode and effect analysis (FMEA), environmental impaet assessment, and risk analysis. FMEA was used to conduct a reliability analysis, EIA was used to calculate the concentration of the flared gas eomposition partieles affeeting the local environment, and risk assessment was employed to find out the hazards and exposure in the case study in order to assure safety. Cost estimation was used to ealculate the capital investment cost for each option considered. Information and expert opinions were eaptured through interviews and questionnaires.
