    Uncertainty of net present value calculations and the impact on applying integrated maintenance approaches to the UK rail industry

    Get PDF
    The Public performance indicator (PPI) is an important Key Performance Indicator for Network Rail and monitored carefully by the organisation and their external stakeholders. Condition monitoring is of increasing interest within network rail as a suitable method for increasing asset reliability and improving the PPI metric. As condition monitoring methods are identified each will need assessment to establish the cost and benefit. Benefit can be measured in cost savings as poor PPI performance results in fines. Within many industries Net Present Value (NPV) calculations are used to determine how quickly investments will break-even. Cost-risk is a term that is used to describe the financial impact of an unexpected event (a risk). This paper outlines a more detailed approach to calculating NPV which considers the cost-risk effect of changes of the denial of service charging rate. NPV prediction is of importance when assessing when to deploy different fault detection strategies to maintenance issues, and therefore the cost-risk of the NPV calculation should be used to support asset management decisions

    Situating the Next Generation of Impact Measurement and Evaluation for Impact Investing

    In taking stock of the landscape, this paper promotes a convergence of methods, building from both the impact investment and evaluation fields.The commitment of impact investors to strengthen the process of generating evidence for their social returns alongside the evidence for financial returns is a veritable game changer. But social change is a complex business and good intentions do not necessarily translate into verifiable impact.As the public sector, bilaterals, and multilaterals increasingly partner with impact investors in achieving collective impact goals, the need for strong evidence about impact becomes even more compelling. The time has come to develop new mindsets and approaches that can be widely shared and employed in ways that will advance the frontier for impact measurement and evaluation of impact investing. Each of the menu options presented in this paper can contribute to building evidence about impact. The next generation of measurement will be stronger if the full range of options comes into play and the more evaluative approaches become commonplace as means for developing evidence and testing assumptions about the processes of change from a stakeholder perspective– with a view toward context and systems.Creating and sharing evidence about impact is a key lever for contributing to greater impact, demonstrating additionality, and for building confidence among potential investors, partners and observers in this emergent industry on its path to maturation. Further, the range of measurement options offers opportunities to choose appropriate approaches that will allow data to contribute to impact management– to improve on the business model of ventures and to improve services and systems that improve conditions for people and households living in poverty.

    Performance Evaluation of the FBG Sensing Device and Comparison with Piezoelectric Sensors for Acoustic Emission Detection

    In-service structural health monitoring (SHM) of engineering structures has assumed a significant role in assessing their safety and integrity. As the most mature technique in fiber-optic field, Fiber Bragg Grating (FBG) sensors have emerged as a reliable, in situ and nondestructive tool for monitoring and diagnostics in large-scale structure. Main objectives of this work are to evaluate and compare the acoustic emission (AE) sensing characteristics simultaneously with FBG sensor array and piezoelectric (PZ) sensors. The pencil-lead-break (PLB) test, ball dropping test and the excitation from the PZ transducer are treated as the AE source which conducted on the platy and blocky structure respectively for acoustic wave. The source repeatability will be verified to choose the source with more stable performance. A commercial 4-channel FBG AE detection device was used to compare with the PZ sensor on the amplitude and frequency response which can indicate the sensitivity of the sensors. The low sensitivity and low sampling rate are the main issue for the engineering application of the FBG sensors. Besides, the sensitivity and directional dependence of the FBG sensor have been discussed. It shows that the encapsulation method of the FBG sensor will impact both of them significantly

    Performance Measurement in State Economic Development Agencies: Lessons and Next Steps for GDITT

    Get PDF
    The purpose of this project was to develop the basis for a comprehensive performance monitoring system for the Department of Industry, Trade and Tourism. This performance monitoring system involved the development of performance measures as well as methods and processes for the collection, maintenance and reporting of the related data. As a result of the work completed for this project, GDITT has a workable set of performance measures for its major divisions: Economic Development, Film, Video and Music, International Trade, and Tourism.

    What Makes A Court Problem-Solving: Universal Performance Indicators for Problem-Solving Justice

    Get PDF
    This report identifies a set of universal performance indicators for specialized "problem-solving courts" and related experiments in problem-solving justice. Traditional performance indicators related to caseload and processing efficiency can assist court managers in monitoring case flow, assigning cases to judges, and adhering to budgetary and statutory due process guidelines. Yet, these indicators are ultimately limited in scope. Faced with the recent explosion of problem solving courts and other experiments seeking to address the underlying problems of litigants, victims, and communities, there is an urgent need to complement traditional court performance indicators with ones of a problem-solving nature. With funding from the State Justice Institute (SJI), the Center for Court Innovation conducted an investigation designed to achieve three purposes. The first was to establish a set of universal performance indicators against which to judge the effectiveness of specialized problem-solving courts, of which there are currently more than 3,000 nationwide. The second purpose was to develop performance indicators specific to each of the four major problem-solving court models: drug, mental health, domestic violence, and community courts. The third purpose was to assist traditional court managers by establishing a more limited set of indicators, designed to capture problem-solving activity throughout the courthouse, not only within a specialized court context
