Construction dispute reduction through an improved contracting process in the Canadian context

Hartman, Francis T. January 1993 (has links)
This thesis presents a new approach to construction contracting in North America. This new approach is referred to as the New Canadian Contracting Method (NCCM). It has been developed as a result of research into the existing contracting process used in North America generally and in Canada specifically. The NCCM addresses four main issues that were identified in the research, namely: confrontational construction; dispute resolution problems and costs; the project execution team selection process; completion of contracts. The NCCM addresses these issues without being prescriptive or by attempting to address one party's agenda over another. This is because these two approaches have been common to previous and unsuccessful attempts at addressing these issues. The new contracting method proposes the following four elements. First the designer and contractor are selected on a qualification basis. The designer and the contractor may be brought on to the project team at a time when the contractor can add to constructability by having input into production of the working drawings. Second, a commercial risk evaluation process is introduced as a part of the negotiation or tendering stage. This approach is innovative, and allows both the owner and the contractors to have input to the identification and allocation of risk in the contract. Third the administration of the contract involves a Proactive Mediation Process that is designed to reduce the incidence of conflict and lower or eliminate conflict resolution costs. Fourth the close-out of contracts is formalized with a process for realigning the completion of the contract. This is done by reassigning outstanding obligations to the best advantage of all parties. The draft process was tested for validity. The consensus was that, with some modifications (included in the thesis), the NCCM could be useful to the Canadian construction industry.

Risk as the key criterion for intervention? : a study of four psychiatric settings

Nmeterson, Nathaniel Martey January 2003 (has links)
Risk management has become one of the major issues facing nurses. Its role in healthcare organisations has gained increased recognition as the consequences of risky decisions have become more visible. The project was primarily concerned with exploring issues that confront one particularly group of professionals - psychiatric nurses - as they experience a particular approach to risk management. The study used the advancement of the risk management agenda as an opportunity to examine the nature of risk management and consider what nurses understood to be the nature of a proficient risk management. Case studies analyses were provided of four psychiatric units. Data were collected over four years through observation, interviews and documents. It used an integrated approach to examine the development of risk management processes in its social, environmental and clinical contexts. Drawing on sociological theories of risk, it introduced the theoretical framework of arena concept and explained how this concept affect the decision making process. It was suggested that the decision making process is a social process in which regulative, normative and institutional effects influence the perceptions and management of risk. The processes were shown to involve a dynamic interweaving of certain structured interests mixing with both clinical and societal considerations inside and outside the healthcare settings. Risk was considered to be the outcome of a complex process of social construction comprising of cultural and political elements in which both the influence of institutions and individual evaluation can be discerned. The findings showed that psychiatric nurses presented a creative and critical understanding to the issues involved in risk management by adopting and absorbing new approaches to risk management in order to advance their professional work. This study formulates a new conceptual framework of understanding risk management in organisational context and contributes by drawing together previously unrelated research and shows how it provides the basis for a theoretical model risk management that is more complete.

A knowledge-based decision support system for computer disaster prevention in IT centres

Danish, Tawfig Yousef January 1994 (has links)
In analysing the extent to which adequate research work may have been undertaken in the specific area of computer disaster prevention, it was found that little work had been done. In the real-life situation, it was also concluded that, in the vast majority of cases, no adequate disaster prevention controls were in use at IT installations. Guidance for the analysis and management of the risk associated with computer disasters, as a result, has also been inadequate and lacking in uniformity, specially in the areas of risk identification and risk entities interactions and relationships. This research has involved developing and delivering a methodology which would help IT risk managers in implementing effective computer disaster prevention controls. A knowledge based system (KBS) approach has been used to build a prototype system which provides full support in this important area of decision making, and to show how the representation of risks can be handled.

Risk management for property casualty insurance companies

Mutenga, Stanley January 2001 (has links)
This thesis addresses the need to reduce inefficiencies in management of insurance company risk capital. The laxity in managing the cost of capital is a result of dysfunctional property/casualty risk classification and capital accumulation practices in the insurance industry. We reclassify risk based on both peril and financial functional features, in order to capture all the facets of risk affecting a firm and ultimately to achieve optimal capital allocation. With the purpose of reducing inefficiencies in mind, we explore and isolate the impact of regulation on insurance company profitability. We use barrier option pricing models to mimic the impact of solvency requirements on firm-wide risk. This methodology of measuring risk is better than plain vanilla option pricing models, in that, through the option to an early default, we are able to capture the economic significance of financial distress, and allocate firm-wide risk capital. The firm-wide risk is incidentally used to empirically test the impact of risk on the cost of carry, the quality of operational profitability and forward asset commitment per unit of liabilities. Our empirical test confirms a strong relationship between firm-level risk, and the cost of carry, return on policyholders' surplus and the cost of capital per contract underwritten. The results are better than previous results obtained using plain vanilla option-pricing models and reveal the importance of incorporating solvency requirements in defining the economic significance of insolvency. The results also points to the importance of advised risk classification procedures to the whole process of integrated risk measurement and financing, which we explore in this study.

Essays on Incorporating Risk Modeling Techniques in Agriculture

Larsen, Ryan A. 2011 August 1900 (has links)
Measuring, modeling, and managing risk has always been an important task for researchers. Many of the traditional assumptions relied on in risk research, such as the assumption of normality and single period optimization, have proven too restrictive and alternative methods have been developed. The objective of this dissertation is to explore and apply these tools to analyze geographical diversification. The first step to analyze geographical diversification is to understand how different climate and spatial variables impact yields. Yield dependencies for wheat, cotton, and sorghum are estimated using linear correlation and copulas. The copulas provide an alternative to linear correlation. The results of the different dependency estimations indicate that there is a significant difference between the results. The next step is to analyze geographical diversification in a portfolio setting. Traditional portfolio optimization has assumed that risk and dependence are symmetric. Using a single period model, an asymmetric risk measure, conditional value at risk, and asymmetric dependence measure, copulas, are implemented into the portfolio optimization model. The efficient frontiers under both symmetric and asymmetric assumptions show that ignoring the asymmetric nature of the data could lead to optimal portfolio allocations that could underestimate the actual risk exposure. The implication of these results provides researchers with more motivation to move beyond the standard assumptions of linear correlation and normality. Building on the single period problem, a multi-period portfolio model is formulated using discrete stochastic programming. One key in formulating a discrete stochastic program is the representation of uncertainty. Scenario generation is a method to obtain a discrete set of outcomes for the random variables. A moment matching routine is developed to capture the first four moments of the variables and the multivariate relationship is modeled using copulas. The results show that the moment matching routine closely captures the higher moments of the data. The results also indicate that there are possible gains from geographical diversification. Wealth levels increased for all three regions when production is diversified over the different regions. The optimal land allocation was dependent upon the base acreage assumption

FX Spot Trading and Risk Management from A Market Maker’s Perspective

Yang, Mu January 2011 (has links)
Due to the rapid development of computing technology and faster growth of financial industry, Foreign Exchange high-frequency trading has become substantially more prominent to today's market players, especially to bankers and market makers. This research aims at introducing today's FX high-frequency trading structure and discussing how a market maker can effectively reduce downside risk when market faces a huge upward or downward stress. An Exponential Moving Average operator is introduced and implemented using a Matlab software for tick-by-tick data analysis. Simulation framework for market high-frequency data and client trading flow is also introduced and implemented using the Matlab software. Real-time P&L calculation is introduced and used to determine the performance of a proposed risk hedging strategy. On the other hand, due to the financial crisis we experienced in 2007, 2008, and 2009, we analyze the tail risk of foreign exchange market. Extreme Value Theory (EVT) has been applied to real EUR/USD data, which contains eight-year daily closing exchange rate. An extension of from EVT to Value-at-Risk (VaR) calculation is introduced. We also consider the volatility clustering issue in asset returns and demonstrate how GARCH model can be applied for VaR calculation. Lastly, we propose a method of using VaR as a high-frequency risk measure for risk hedging strategies during intra-day trading.

Riskhantering i projekt : Modell för uppföljning / Risk Management in projects : Methodology for monitoring risks

Ahlmark, Peter January 2010 (has links)
In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket. The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan). In this thesis a particular emphasis will be put on theimportance of communication for risk management within anadministration. Better bottom-up and top-down communication andfeedback will enable improvements and more transparent riskmanagement especially at higher levels in the agency such as theboard of the project managers. The tool that will be proposed in thisthesis builds on the current tools used at Vägverket and Banverketthus assuring a smooth transition towards a unified tool.

Risk Management in M-Commerce projects : A Case Study of M-Commerce project in Trollhättan

Meng, Liuchun January 2012 (has links)
Due to its inherent characteristics such as ubiquity, personalization, flexibility, and dissemination, mobile commerce promises business unprecedented market potential, greater productivity and higher profitability. With this in mind, it is perhaps not surprising that mobile commerce is growing much faster than its fixed counterpart. Unlike e-commerce, m-commerce is personalized and there is a need for a novel approach to evaluating risk management in m-commerce projects. Result in the increase of risks management in m-commerce. Besides the business core activities, the increased use of derivative products by both financial and non-financial institutions and recent events or scandals continue to demonstrate the need for enhanced standards and processes of control over risk. In this thesis, I attempt to introduce a new method for performing risk analysis studies by effectively utilizing the existing risk management process framework with adoptions of analysis approach in m-commerce projects. It will provide a sequencing of the core part of the risk management process into sub-processes for identify context, identify risks, analyse risks, evaluate risks and treat risks in different respects of m-commerce. Moreover, it seems that the integration of risk management process and some analysis method indeed provided very useful new insights. To be able to fulfil the purpose of study, qualitative research method was considered, using an inductive approach of a single case study of m-commerce project in Trollhättan with m-commerce related research literature and scenario for development of restaurant in university west as source of data. Based on the analysis, a number of observations were put forward in the conclusion. To begin with the strategy in relation to management structure will be considered. In addition, the role of information technology security is considered in risk management. Meanwhile, the good governance and risk management according to m-commerce application in risk management system and corporate governance are included in the discussion. In attempt of risk management in the m-commerce projects, this thesis examines the issues in one case of m-commerce project in Trollhättan not only information secure issues and some technical viewpoints in m-commerce project but also from the project management's perspective. The contribution of the thesis will be introducing a new framework/module for performing a risk analysis studies in m-commerce projects domain and a proposal for risk management in the m-commerce projects case of Trollhättan.
