The Cost

On-line compressor washing has shown to relatively improve engine performance by decelerating the rate of engine degradation due to fouling during operation. There is a number of influencing parameters that determine the economic benefit, some of which includes the frequency of washing, the effectiveness of washing liquid and the size of the engine or power output produced. This study, unlike others, explores the cost-benefit analysis, focusing on the viability of compressor washing for various gas turbine engines or rated capacities, ranging from a 5MW single machine to a 300MW unit. Fouling degradation trend obtained from actual machine operation have been implemented and the application of different washing frequencies and recoveries of lost power shows the significantly higher return on investment for the larger engines in comparison to the smaller engines. This is partly due to the fact that the washing equipment cost, though increases with engine size, does not increase proportionally. Another contributing factor is the cost penalty per MW when the same level of degradation is implemented for all the engines. Some of the key aspects captured in this study are the capital and maintenance cost used, that relates to the different engine sizes, therefore ensuring a more indicative basis for comparing the viability of the different engines. This also includes the estimation of washing liquid utilised based on their respective typical mass flows. When the number of engines increases to 4 for a given operations, the return on investment increases by a factor of 3.5. This is possible as one wash unit can be applied to more than one engine within proximity. Higher return on investment is achieved when more than one relatively small engine is used to obtain a higher total power output. This is about 1.7 times higher for four 63MW engines versus one 255MW, as relatively cheaper washing equipment is implemented for the same total operational capacity. The study also shows that on-line washing is not always viable for electric power generation. This is observed for smaller light-duty engines, especially in situations when the level of fouling is relatively low.

AbstractObjectiveTo demonstrate the application of economics to health care preparedness by estimating the financial return on investment in a substate regional emergency response team and to develop a financial model aimed at sustaining community-level disaster readiness.MethodsEconomic evaluation methods were applied to the experience of a regional Pennsylvania response capability. A cost-benefit analysis was performed by using information on funding of the response team and 17 real-world events the team responded to between 2008 and 2013. By use of the results of the cost-benefit analysis as well as information on the response team’s catchment area, a risk-based insurance-like membership model was built.ResultsThe cost-benefit analysis showed a positive return after 6 years of investment in the regional emergency response team. Financial modeling allowed for the calculation of premiums for 2 types of providers within the emergency response team’s catchment area: hospitals and long-term care facilities.ConclusionThe analysis indicated that preparedness activities have a positive return on their investment in this substate region. By applying economic principles, communities can estimate their return on investment to make better business decisions in an effort to increase the sustainability of emergency preparedness programs at the regional level.

In July 2011, the National Shipbuilding Research Program (NSRP)awarded the project entitled “Reduction of Total Ownership Costs Through Application of Design For Maintenance (DFM) and Repair Methodologies Project” a collaborative shipyard-led research project, supported by Bollinger Shipyards(Prime), BAE Systems Southeast Shipyards, Vigor Shipyards, the Trident Refit Facility in Kingsbay, GA, General Dynamics Electric Boat, General Dynamics NASSCO, and the Naval Center for Cost Analysis at NSWC-Carderock. Through this customer-centric project, nearly 40 DFM workshops were held with the deck-plate repairers at public and private shipyards across the US to identify major maintenance cost drivers, maintenance cost reduction opportunities, and deliver design rules to reduce total ownership costs to ship owners based on Design for Maintainability (DFM) principles. This paper will provide an understanding of the process used to develop the DFM information and will discuss the DFM principles applied and highlight the “good practice” design rules that resulted from this effort. The paper will also describe the Cost Benefit Analysis process and templates developed through the project, along with provide an appreciation of the potential cost benefits associated with the implementation of DFM principles. The DFM database, also developed through the project, with over 1000+ repair-based cost reduction strategies will also be highlighted.

Therapy Programme

The economic argument underpinning the Improving Access to Psychological Therapy programme has been a central component in its initial and continued investment. Using open-access data, this article undertook a cost-benefit analysis using the programme’s key defining outcomes to determine its return-on-investment. It was found that in terms of investment and efficiency gains, the programme was in the higher ends of the cost spectrum for delivering psychological therapies. Although cost-estimates appear promising at first, when set in the context of a lower number of treatment contacts and a high proportion of early disengagement, estimates increased sharply.

This article analyzes definitions and the role of hostile takeovers at the Russian and European markets for corporate control. It develops the methodology of assessing the efficiency of anti-takeover defenses adapted to the conditions of the Russian market. The paper uses the cost-benefit analysis, where the costs and benefits of the pre-bid and post-bid defenses are compared.

Many countries are investing in measures to improve surface water quality, but the investment programmes for so doing are increasingly becoming subject to cost-benefit analysis. Whilst the cost of control measures can usually be determined for individual improvement schemes, there are currently no established procedures for valuing the benefits attributable to improved surface water quality. The paper describes a methodology that has been derived that now makes this possible.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

Key Aspects

The Commission's new Better Regulation package represents a step forward in the European Union’s decade–long journey to bringing coherence and rationality to its legislative and regulatory process. But as the Communication on the package itself suggests, the journey is far from over.The Communication consistently emphasizes the key aspects of good regulation: quality over quantity; taking time to get proposals right; evidence–based decision making; open and continuous consultation to gather evidence from all stakeholders; rigorous impact assessments and cost–benefit analysis; applying these tools to regulatory measures as well as legislation; and implementing a robust ex–post evaluation program. It is important as well that the Secretariat General published unified and detailed guidance for Commission officials on how each step of the regulatory process should work, with a “tool–box” to elaborate further on these steps.All of this is good. Yet in some areas, the Commission misses opportunities to go farther down the good governance road, and in others the guidance needs to be made much more explicit.
