Cost-benefit analysis purpose

For the spectroscopist today it is very important to choose the right method, after a cost-benefit analysis, to match the demands of the customer or serve the purpose of his research as effectively as possible. For the characterization of heterogeneous polymers a broad range of methods and instruments is available. We have tried to list the most important of them, and to emphasize their pros and cons when used for polymer imaging. [Pg.557]

As a general rule, simulations based on classical or quantal equations of motion may serve a useful purpose as benchmarks for model calculations. The days where such simulations may be used for routine calculations of stopping parameters are likely to lie quite a few years ahead, even with the present pace of hardware development in mind. Stopping data are potentially needed for 92X92 elemental ion-target combinations over almost ten decades of beam energy and for a considerable number of charge states, and to this adds an unlimited number of compounds and alloys. It seems wise to keep this in mind in a cost-benefit analysis of one s effort. [Pg.108]

As with the translation of clinical outcomes into monetary measures, there also are difficulties associated with combining different outcomes into a common measure in cost-effectiveness analysis. However, it generally is considered more difficult to translate all health benefits into monetary units for the purposes of cost-benefit analysis than to combine clinical outcome measures. Thus, cost-effectiveness analysis is used more frequently than cost-benefit analysis in the medical care literature. [Pg.39]

For the purpose of the cost-benefit analysis semi-variable costs are considered to be fixed costs. It is assumed that the reduction of the volume of one product will not lead to a reduction of the number of operators and/or lab personnel. [Pg.164]

Environmental Impact Assessment (EIA) has evolved as a comprehensive approach to project evaluation, in which environmental factors, as well as economic and technical considerations (e.g. Cost Benefit Analysis), are given appropriate consideration in the decisionmaking process. The purpose of an EIA study is to determine the potential environmental, social and health effects of a proposed development. It attempts to define and assess the physical, biological and socio-economic effects, so that logical and rational decisions are made. The identification of possible alternative sites and/or processes may assist in the reduction of potential adverse impacts. [Pg.68]

For food safety purposes the overriding aim is that food contamination should be reduced to the lowest practicable level, bearing in mind the potential costs and benefits involved. Since it is difficult to establish cause and effect relationships following long-term (chronic) exposure at low concentrations, it may be necessary to base action on prudence rather than on proven harm to health. However, if this approach is to maintain the confidence of both consumers and producers of food, a rational evaluation of all relevant information is required so that the balance between the risks and benefits of veterinary drugs can be assessed. Information on the incidence of potentially harmful drug residues is fundamental to this cost-benefit analysis so too is the consumption of the commodities involved (particularly for susceptible consumers or those consumers who eat more). Account must also be taken of the potential fall in food production if a drug is controlled or prohibited, and also the animal health and welfare implications that may result from the restriction of an animal medicine for which there may be no effective alternative. [Pg.134]

The results from lengthy exposure periods are of course more relevant for practical purposes e.g. for classification of the corrosivity of atmosphere on a given location or for cost-benefit analysis. In this case the corrosion rate may be assessed from yearly mean values of the concentration of pollutants and from the time-of-wetness class estimated from meteorological measurements. [Pg.106]

Application of these measures to reduce the frequency of reanalysis required in the radioanalytical chemistry laboratory can be justified by a cost-benefit analysis. The general purpose of supporting acceptance of analytical results has a less determinate economic benefit. The time and effort devoted to QA has increased from about 10% of the total analytical workload to 25-30% at present, as regulatory agencies have required more quality control (QC) measurements and more supporting documents. This increasing cost includes QC measurements, organization and actions instituted to ensure correct and defensible data output. The costs and benefits of QA are considered in Section 11.4. [Pg.222]

The cost—benefit analysis (CBA) approach (Hundloe et al., 1990), which seeks to express impacts in monetary units, falls into the first category. It is a method of assessing the consequences of projects and actions, in which the estimated benefits are weighed against the costs. For this purpose, all consequences must be measured in the same unit, and the traditional choice of unit is money. To be explicitly included in a CBA, then, environmental changes must be valued in monetary terms. [Pg.158]

ABSTRACT The increased use of wireless networks in schools has created concern among many parents and scientists is the low levels microwave radiation emitted by the transmitters harmful The scientific community does not provide a clear answer, there are uncertainties about the consequences of the radiation. This has raised the issue of applying the precautionary principle and switch off the wireless networks and use a safer alternative, for example a cable system. However, the decision-makers argue that the uncertainties and the risk need to be balanced with the benefits of the activity. Some type of cost-benefit analysis is required. But it is not obvious how such an analysis should he performed in a case like this, and the purpose of this paper is to present and discuss two possible approaches, one based on willingness to pay and one based on expected net present value calculations. [Pg.943]

To attend the purpose of this paper, a systematic model to support the cost-benefit analysis of ergonomics projects (Da Silva 2012) was applied in a southern Brazilian large auto parts manufacturer. The analyzed company is an auto parts manufacturer that provides to an also large car manufacturer. There are more than 1500 workers at their site and several ergonomics difficulties mainly on the production. The company was visited on 2013 and the model was applied with the acceptance of the board directors. [Pg.120]

The standard approach to evaluating the impact of projects consists of what we usually call Utilitarianism and derivatives of it (such as cost-benefit analysis (CBA)). In this section I highlight the main features of this approach and in the following look at some of the problems associated with it. Criticism of Utilitarianism is, of course, nothing new but for our purposes we want to tie in those critiques to a better understanding of the nature of its drawbacks when applied to the environmental problem. In particular, we want to ask does the standard approach miss out on some ethical considerations ... [Pg.131]

There are two main approaches to informing decisions that take account of economic factors. One is cost benefit assessment (CBA) and the other is multicriteria decision analysis (MCDA). It is not the purpose of this document to provide detailed guidance about these techniques, but we offer some comments in the context of standard setting (Text Box C). For a more detailed appreciation of CBA, refer to... [Pg.21]

Thus, the Executive Order requires that agencies affected by the order employ cost-benefit criteria in developing and issuing regulations. The tool to be applied for that purpose is the Regulatory Impact Analysis. [Pg.167]

Usually the process industry level of risk for a particular facility is based on one of two parameters. The average risk to the individual i.e., Fatality Accident Rate (FAR) or Potential Loss of Life (PLL) or the risk of a catastrophic event at the facihty, a Quantified Risk Analysis (QRj ). The risk criteria can be expressed in two manners. Risk per year (annual) or facihty risk (lifetime). For purposes of consistency and familiarity, all quantifiable risks are normally specified as aimually. Where value analysis is appHed for cost comparisons of protection options, a lifetime risk figure is normally used to calculate the cost-benefit value. [Pg.148]

Polymer/additive analysis greatly benefits from high-resolution mass data, which often leads to unambiguous identification of (known) additives. However, the investment and operating costs of this instrument do not easily justify its (exclusive) use for the purpose of routine polymer/additive analysis. Analysis of organic polymer additives by means of mass spectrometry is aided by the utilisation of precursor ion and second-generation product ion (MS3) scanning experiments [169], A four-sector... [Pg.388]

The third axis in Fig. 1 is that of the perspective of an economic analysis of medical care. Costs and benefits can be calculated with respect to society s, the patient s, the payer s, and the provider s points of view. A study s perspective determines how costs and benefits are measured, and the economist s strict definition of costs (the consumption of a resource that could otherwise be used for another purpose) may no longer be appropriate when perspectives different from that of society as a whole are used. For example, a hospital s cost of providing a service may be less than its charge. From the hospital s perspective, then, the charge could be an overstatement of the resources consumed for some services. However, if the patient has to pay the full charge, it is an accurate reflection of the cost of the service to the patient. Alternatively, if the hospital decreases its costs by discharging patients early, the hospital s costs may decrease, but patients costs may increase because of the need for increased outpatient expenses that are not covered by their health insurance plan. [Pg.41]

Microfluidic technology for chemical or bioanalytical purposes concerns the precise control of fluids in a limited space, which may be intentionally patterned on chips, because a number of valuable benefits are expected from such systems [1,2]. As many articles and reviews have pointed out, the alleged advantages include reduced reagent consumption, short analysis time, a small-sized scale, low cost, and high sensitivity. Over the last two decades, there has been an explosive development of miniaturized analytical systems and related techniques based on microfluidics for chemical analysis, bioanalysis, clinical diagnostics, and other applications [3-15]. [Pg.118]

The results of this analysis can be used for policy and planning purposes to show the incremental benefit of AP over and above the contribution of SP. This analysis has fully exploited published data to measure the likely contribution of AP and SP in Italy between the 1970s and 1990s. The cross-sectional and longitudinal surveys have provided a valid base to produce a method that can help policy makers to advocate the extra benefits of AP. Even if this natural experiment cannot produce the same evidence as a randomized community trial, the causal inference between the increase in urinary iodine and the decline in goiter with and without AP is clear, and the incremental cost-effectiveness of AP can be estimated. [Pg.786]

The purpose of economics is, above all, better economic policy, but current economic doctrine surrounding the definition and measurement of well-being is seriously misguided. We have seen that the treatment of all outcomes as commodities is untenable in matters of life and health it is equally inappropriate where policies can affect other constitutive goods - in particular, personal freedom. But it is not only the special attributes of human life that undermine the usefulness of willingness to pay (and benefit-cost analysis generally) as the sole criterion for public policy. A major contention of this book has been that private preferences are just that private. Public policy must be based on public preferences, views... [Pg.239]

The process energy optimization starts with defining a basis in terms of feed and product slates, process configuration, and operating conditions. The base case is simulated to mimic existing operations. Pinch analysis is performed on the base case with the purpose of identiiying improvement options. Then costs and benefits of each option are determined and the eonstraints are identified. [Pg.488]

Accident Prevention From a safety point of view, a primary purpose of analysis is to prevent accidents. It is important to communicate with managers and explain what hazards exist and what controls to implement. Analysis may help determine if one can eliminate or reduce hazards at a reasonable cost. Analysis may help determine if controls are effective and provide the benefits anticipated. [Pg.538]
