Abstract The cost of corrosion was estimated for refinery crude oil distillation units in a detailed study. This program was conceived as the first step in determining the cost of refinery corrosion on a unit throughput basis. A knowledge of the overall cost of corrosion is regarded by management as a valuable aid in assigning manpower and facilities most effectively to corrosion work. Capital, maintenance and operating costs were all considered. A significant “result of this cost study was that the actual cost of corrosion was far less than prior estimates by the industry would have predicted. Of equal importance are the methods evolved in gathering and analyzing the various types of cost data. In their general form these methods should be applicable in corrosion cost studies for all types of process units. 1.2.2

Objectives. Cost studies can provide useful guidance, so long as they adhere to accepted methodology. Cochlear implants (CIs) are electronic devices introduced surgically into the inner ear. It is a relevant example to review cost study analyses because of its costliness. The aim of this study was to review relevant published cost studies of CI to analyze the method used.Methods. First, we described the key points of cost study methodology. Cost studies relating to CI were systematically reviewed, focussing on an analysis of the different methods used.Results. The methods, data sources, and estimated cost categories in each study varied widely. The paper showed that cost studies adopted significantly different approaches to estimate costs of CI, reflecting a lack of consensus on the methodology of cost studies.Conclusion. To increase its credibility, closer agreement among researchers on the methodological principles of cost studies would be desirable.

The Cost

The present study aims at estimating the total cost of MS in Europe based on actual cost data from nine countries and published epidemiological evidence. The epidemiological data are reported as 12 months prevalence estimates and cost data calculated as annual cost per patient at given levels of disease severity. Cost data are extrapolated to the rest of Europe based on a model, using economic indexes adjusting for price level differences in different sectors between countries. The aggregated annual cost estimates are presented in Euro for 2005. In 28 European countries with a population of 466 million, an estimated 380 000 individuals are affected by MS. The total annual cost of MS in Europe is estimated at 12.5 billion in year 2005, corresponding to a cost of 27 per European inhabitant. Direct costs represent slightly more than half of the total cost (6.0 billion). Informal care is estimated at 3.2 billion, and indirect costs due to morbidity at 3.2 billion. Thus, the largest component of costs is found outside the formal health care sector. Although our model appears to predict costs reasonably well, when comparing to previous national studies not included in the estimates, there are considerable uncertainties when extrapolating cost data across countries even within Europe. These weaknesses can only be overcome by collecting primary data. Multiple Sclerosis 2007; 13: 1054—1064. http://msj.sagepub.com

The Cost

A novel approach to the calculation of the cost of crude oil distillation products is proposed in this paper. The approach is based on the primary exergy “invested” in the entire process, from extraction to final dispatch, in a well-to-final use perspective including all externalities: capital, labor and environmental remediation cost. The method follows the Extended Exergy Accounting (EEA) theory, and results in a quantifier, the specific extended exergy cost eec, expressed in Joules of primary exergy globally used in the process per Joule of final product. This indicator is not meant to substitute the monetary cost currently adopted in all transactions, but rather to complement it by providing designers, industry managers and energy policy planners with a thermodynamically-sound basis for assessing how far a certain productive chain is from being “sustainable” in terms of primary resources. Several different processes are analyzed, and the quantitative differences in the final eec are calculated and discussed. The conclusions contain some suggestions for a general reassessment of our approach to the exploitation of primary energy resources.

This study aims to find a comparison of the calculation of the cost of goods manufactured in the CV. Mitra Setia Blitar uses the company's method and uses the Job Order Costing (JOC) method. The method used in this study is quantitative. The types of data used are quantitative and qualitative. Quantitative data is in the form of map production cost data while qualitative data is in the form of information about map production process. The result of calculating the cost of production of the map between the two methods results in a difference of Rp. 306. Calculation using the company method is more expensive than using the Job Order Costing method. Calculation of cost of goods manufactured using the company method is Rp. 2,205,000, - or Rp. 2,205, - each unit. While using the Job Order Costing (JOC) method is Rp. 1,899,000, - or Rp 1,899, - each unit. So that the right method used in calculating the cost of production is the Job Order Costing (JOC) method

Renewable and sustainable energy has an evolving story as the ongoing trade war in the word is influencing crude oil prices. Moreover, the global warming is an inevitable consequence of the worldwide increasing rate of fossil fuel utilization which has persuaded the governments to invest on the clean and sustainable energy resources. In recent years, the cost of green energy has tumbled, making the price of renewables competitive to the fossil fuels. Although, the hydrogen fuel is still extremely expensive compared to the crude oil price, investigations about clean hydrogen fuel production and utilization has been developed significantly which demonstrate the importance of the hydrogen fuel in the future. This article aims to scrutinize the importance of green hydrogen fuel production from solar/wind energy.

Of many techniques that are used to optimize production and costs, the studies conducted within a profile company lead to our choice for testing the 6Sigma method (the most used method in the automotive industry) in view of the economic efficiency applied in the wood Industry company. This method measures how many flaws exist in a process and determines in a systematic way how to improve it by technical overhauling and eliminating or minimizing the process for efficiency. This research article aims to study the state of research on the optimization of the production process through technical overhauling for panels reconstituted from solid wood and ways to make production more efficient by cutting costs through technical overhauling. From preliminary research, we estimate that all the items founded and others that will result from further research will result in a significant decrease in production costs that are reflected in the cost of the finished product and consequently in increasing the yield of the company by maximizing its profit. At the same time it may be the basis of future research studies in the field. The easier it is to maximize profits, the lower the operating costs are and the higher recovery rate of investments are, that will result a change in the operating mode: “working smarter not harder”.

AbstractGlobal deterioration of marine ecosystems, together with increasing pressure to use them, has created a demand for new, more efficient and cost-efficient monitoring tools that enable assessing changes in the status of marine ecosystems. However, demonstrating the cost-efficiency of a monitoring method is not straightforward as there are no generally applicable guidelines. Our study provides a systematic literature mapping of methods and criteria that have been proposed or used since the year 2000 to evaluate the cost-efficiency of marine monitoring methods. We aimed to investigate these methods but discovered that examples of actual cost-efficiency assessments in literature were rare, contradicting the prevalent use of the term “cost-efficiency.” We identified five different ways to compare the cost-efficiency of a marine monitoring method: (1) the cost–benefit ratio, (2) comparative studies based on an experiment, (3) comparative studies based on a literature review, (4) comparisons with other methods based on literature, and (5) subjective comparisons with other methods based on experience or intuition. Because of the observed high frequency of insufficient cost–benefit assessments, we strongly advise that more attention is paid to the coverage of both cost and efficiency parameters when evaluating the actual cost-efficiency of novel methods. Our results emphasize the need to improve the reliability and comparability of cost-efficiency assessments. We provide guidelines for future initiatives to develop a cost-efficiency assessment framework and suggestions for more unified cost-efficiency criteria.

The Cost

The roadway infrastructure constantly deteriorates because of environmental conditions, but other factors such as exposure to heavy trucks exacerbates the rate of deterioration. Therefore, decision-makers are constantly searching for ways to optimize allocation of the limited funds for repair, maintenance, and rehabilitation of New Jersey’s infrastructure. New Jersey legislation requires operators of overweight (OW) trucks to obtain a permit to use the infrastructure. The New Jersey Department of Transportation (NJDOT) issues a variety of permits based on the types of goods carried. These permits allow OW trucks to use the infrastructure either for a single trip or for multiple trips. Therefore, one major concern is whether the permit revenue of the agency can recoup the actual cost of damage to the infrastructure caused by these OW trucks. This study investigates whether NJDOT’s current permit fee program can collect enough revenue to meet the actual cost of damage to the infrastructure caused by these heavy-weight permit trucks. The infrastructure damage is estimated by using pavement and bridge deterioration models and New Jersey permit data from 2013 to 2018 containing vehicle configuration and vehicle route. The analysis indicates that although the cost of infrastructure damage can be recovered for certain permit types, there is room for improvement in the permit program. Moreover, based on permit rules in other states, the overall rank of the New Jersey permit program is evaluated and possible revisions are recommended for future permit policies.
