    Uncertainty Quantification in Fatigue Crack Growth Prognosis

    Get PDF
    This paper presents a methodology to quantify the uncertainty in fatigue crack growth prognosis, applied to structures with complicated geometry and subjected to variable amplitude multi-axial loading. Finite element analysis is used to address the complicated geometry and calculate the stress intensity factors. Multi-modal stress intensity factors due to multi-axial loading are combined to calculate an equivalent stress intensity factor using a characteristic plane approach. Crack growth under variable amplitude loading is modeled using a modified Paris law that includes retardation effects. During cycle-by-cycle integration of the crack growth law, a Gaussian process surrogate model is used to replace the expensive finite element analysis. The effect of different types of uncertainty – physical variability, data uncertainty and modeling errors – on crack growth prediction is investigated. The various sources of uncertainty include, but not limited to, variability in loading conditions, material parameters, experimental data, model uncertainty, etc. Three different types of modeling errors – crack growth model error, discretization error and surrogate model error – are included in analysis. The different types of uncertainty are incorporated into the crack growth prediction methodology to predict the probability distribution of crack size as a function of number of load cycles. The proposed method is illustrated using an application problem, surface cracking in a cylindrical structure

    ‘Value for Whom, by Whom’: Investigating Value Constructs in Non-Profit Project Portfolios

    Get PDF
    In most non-profit organisations (NPOs), there are multiple programs, projects or initiatives running simultaneously. The management of multiple projects in organisations can be coined as project portfolio management (PPM) (Archer & Ghasemzadeh 1999; Pennypacker & Dye 2002).  In any project-based organisation, it is critical that selected projects align with and deliver the organisation’s strategy or mission. Decisions about project funding are strategic decisions, particularly when there are resource limitations. In PPM decision making, the allocation of resources to projects requires a clear judgement of value across multiple perspectives. Value has often been expressed in financial terms, however increasingly research indicates that non-financial considerations are equally important in evaluating value.A key task in project portfolio management is to maximise value across the portfolio.  However, value can be a subjective notion, as each person may have different expectations of what is valuable. The involvement of diverse stakeholder interests could create complexities in decision making in non-profit organisations due to value being interpreted in different ways by the stakeholders. Furthermore in order to achieve its purpose, non-profits depend heavily on donors, patrons and sponsors - stakeholders who contribute to the portfolio but are often not the direct recipients of the services provided by the non-profit organisation (Kaplan 2012). Non-profit portfolios often compete with other initiatives for resources and attention from the same donors and sponsors, and may need to constantly justify the value they provide to these stakeholders.Most research about value in PPM has been conducted in the ‘for-profit’ sector. Recent value-based studies in the project portfolio field stress the importance of considering both commercial and non-commercial value in portfolio decision making (Killen, du Plessis & Young 2012; Kopman 2013; Martinsuo & Killen 2014; Thiry 2001, 2002). Non-commercial value includes the ecological, social, and learning dimensions of value (Martinsuo & Killen 2014), whilst commercial value is characterised by financial and economic measures like market value. The research reported in this paper is distinct as it investigates non-commercial value in the non-profit sector. The study extends our knowledge about strategic value and multi-stakeholder management in the non-profit sector. The findings also contribute to the overall understanding of PPM by providing insights about the multi-perspective aspects of value and the management of portfolios in complex environments involving multiple stakeholders.This paper commences with an outline of past and contemporary views about value and discusses how these views might relate to PPM and NPOs. Next, it deliberates the extent to which multi-stakeholder perspectives of value are discussed in the literature.  An empirical qualitative research design is used to explore value in project portfolios from the perspectives of multiple stakeholders in two inter-related case NPOs. The paper concludes with a discussion of the findings to highlight several value perspectives drawn from the non-profit sector that have significant theoretical and practical contributions to understanding value typologies that underline stakeholder constructs of value and decision making in project portfolios

    Energy justice issues in renewable energy megaprojects: implications for a socioeconomic evaluation of megaprojects

    Get PDF
    Purpose – The purpose of this paper is to investigate and discuss stakeholder issues faced by renewable energy megaprojects and in particular solar and wind power projects and their relevance to socioeconomic evaluation of megaprojects. Design/methodology/approach – The paper uses secondary data collected from the recent literature published on stakeholder issues face by mega solar and wind power energy generation projects around the world. The issues are then analysed across specific challenges in five continents where these projects are being developed. The paper then focuses on the literature on energy justice to elaborate the type of issues being faced by renewable energy megaprojects contributing to the achievement of UN Sustainable Goal 7 and their impact on vulnerable communities where these projects are situated. Findings – Renewable energy megaprojects are rarely discussed in the project management literature on megaprojects despite their size and importance in delivering sustainable development goals. While these projects provide social benefits they also create issues of justice due to their impact of vulnerable populations living is locations where these projects are situated. The justice issues faced include procedural justice, distributive justice, recognition inequalities. The type of justice issues was found to vary intensity in the developed, emerging and developing economies. It was found that nonprofit organisations are embarking on strategies to alleviate energy justice issues in innovative ways. It was also found that, in some instances, smaller local projects developed with community participation could actually contribute more equitable to the UN sustainable development goals avoiding the justice issues posed by mega renewable energy projects. Research limitations/implications – The research uses secondary data due to which it is difficult to present a more comprehensive picture of stakeholder issues involving renewable energy megaprojects. The justice issues revealed through thesis paper with renewable energy megaprojects are also present in conventional megaprojects which have not been discussed in the project management literature. Post-COVID19 these justice issues are likely to become mor prevalent due to the pandemic’s impact on vulnerable population exacerbating the issues and increasing their severity on these populations. Therefore it is becoming even more critical to take these into account while developing renewable energy megaprojects. Practical implications – Proper identification and response to energy justice issues can help in alleviating stakeholder issues in renewable energy megaprojects. Social implications – Contributes to the equitable achievement of the United Nations Sustainable Development Goal 7. Originality/value – This paper addresses a gap in the project management literature on the exploration of stakeholder issues on renewable energy megaprojects. It also brings out the importance of justice issues which can assist in expanding stakeholders issues faced by megaprojects as these issues have not received sufficient attention in the past in the project management literature.acceptedVersio
