This paper documents the analysis of the circumstances surrounding fatalities due to flooding in Australia between 1900 and 2015. This longitudinal investigation is important to understand changing trends in social vulnerability and to inform efficient and strategic risk reduction strategies. The basis of this analysis was PerilAUS, Risk Frontiers’...

The economic impact of natural disasters on developing economies can be severe with the recovery diverting scarce funds that might otherwise be targeted at development projects and stimulating the need for international aid. In view of the likely sensitivity of low-lying Pacific Islands to anticipated changes in climate, a 122-year record of major...

Economic losses from natural disasters pose significant challenges to communities and to the insurance industry. Natural disaster mitigation aims to reduce the threat to people and assets from natural perils. Good decisions relating to hazard risk mitigation require judgments both about the scientific and financial issues involved, i.e., the effica...

This paper proposes a new decision support approach for applying stochastic simulation to the multiplicative analytic hierarchy process (AHP) in order to deal with issues concerning the scale parameter. The paper suggests a new approach that captures the influence from the scale parameter by making use of probability distributions. Herein, the unce...
Article
In a recent paper Botha (1995) proposes the use of statistical techniques and models from modem finance to show that the abnormal returns on a firm’s share price in some window period immediately before a specific event was not merely a chance event, but rather that firm-specific information caused material share price changes during the window per...

This study focuses on developing an agricultural investment model based upon proven financial investment portfolio techniques. The model can be used as a tool to diversify agricultural risk over the long-term by optimising the proportion of land allocated to each of the agricultural products, resulting in increased value of the agricultural enterpr...

In 2009-2010 Sydney Water, the primary water utility in Sydney, conducted a comprehensive Smart Metering trial in residential homes in the suburb of Westleigh, in Sydney’s north. The trial involved 1,923 participants residing in 630 households. A whole-of-community method of engagement was applied to capture the views of residents from 12 to 70+ ye...

The Lockyer Valley region in southeast Queensland, Australia experienced extreme flash flooding in January 2011 that resulted in the loss of 19 lives including 12 in the township of Grantham. In order to reduce future risks, the Lockyer Valley Regional Council (LVRC) immediately committed to an innovative community resettlement project, despite an...

A nation-wide survey was conducted in 2010 to investigate the Australian public's attitudes to nuclear power in relation to climate change and in comparison to other energy alternatives. The survey showed a majority of respondents (42%) willing to accept nuclear power if it would help tackle climate change. Following the disaster at the Fukushima D...

This paper presents research into four key stakeholders in flood risk management in Australia: local councils, the insurance industry, the State Emergency Service (SES), and local residents; examining the perception of their own roles and responsibilities, and those of the other stakeholders. Key informant interviews were conducted in four location...
Article
Full-text available
Widespread flooding across eastern Australia between November 2010 and February 2011 has again highlighted the country's susceptibility to natural disasters. The floods have also triggered discussion about flood awareness, risk information, and the role and responsibility of governments, insurance providers and residents. This paper examines the av...

Abstract The birth date distributions of elite male and female footballers in Australia, from junior youth (age 14 and upwards) to senior (professional) players, were examined. A statistically significant relative age effect was found among junior male players, reducing in effect with increasing age. An inter-year relative age effect that became ap...

On 13th January 2011 major flooding occurred throughout most of the Brisbane River catchment, most severely in Toowoomba and the Lockyer Creek catchment (where 23 people drowned), the Bremer River catchment and in Brisbane, the state capital of Queensland. Some 56,200 claims have been received by insurers with payouts totalling $2.55 billion. This...
Article
Full-text available
In much of the developed world, private sector insurance plays an important but often underappreciated role in the management of natural disasters. Insurance works by spreading individual and independent risks across all policyholders. This notion succeeds for uncorrelated risks such as theft and motor accidents, but is problematic where risks are...

Integer programming is used to test the nutritional completeness of two fast-food chains operating in South Africa. McDonald's and Kentucky Fried Chicken. It is shown that a fully nutritional and varied daily diet can be made up from McDonald's menu items, but the same is not true for Kentucky Fried Chicken. This exercise is highly suited to introd...

Full-text available
The finish-line system of a major road race is investigated by means of a simulation model. In an attempt to help race management identify conditions that may lead to congestion of runners at this point. Based on the results of the model, race management was presented with a simple tool which could be used in situ to analyse a given situation, iden...
Article
In this paper, the use of multivariate statistical analysis techniques to aid in conflict analysis in a multi-actor group is demonstrated. In particular, the covariance biplot technique is focused on and the resulting graphical output, called the conflict diagram, is interpreted in terms of relationships between actors, profiles of alternatives und...
Article
Full-text available
Many complex decisions are made in a group environment, where the decision is made jointly by a committee or group structure. The individual group members are often not equally qualified to contribute equitably to the decision process, or may have different saliences (desires) to influence the decision. A quantitative knowledge of the players' deci...
Article
In many negotiating situations one of the bargaining parties is seen to tender proposals (the allocator), with the other party merely accepting or rejecting these proposals (the ratifier). In this paper, we develop an adaptation of the REMBRANDT system for multicriteria decision analysis to offer negotiation decision support to the ratifier in a co...
Article
In an allocation problem to determine a fair distribution of some divisible benefit or cost amongst members of a group, there are often a number of input criteria which may be used to make the allocation. We propose the weighted multicriteria power index, which combines traditional voting power in committees with the concept of criteria weighting,...
Article
The REMBRANDT system for multicriteria decision analysis consists of both the multiplicative variant of the AHP (which employs a method of pairwise comparative judgements by a decision maker to arrive at final impact scores for the alternatives under consideration) and SMART, the simple multiattribute rating technique (which utilizes direct rating...

This paper proposes a model for the representation of a consensus-seeking group decision making process under the multiplicative variant of the analytic hierarchy process (AHP). In particular, it proposes a group preference model which expresses the group's preference intensity judgements as random variables with associated probability distribution...
Article
Run accumulation by a batsman in test or first-class cricket is modelled by means of a Simple Geometric Distribution, and batting performance examined in (batting average, batting consistency) space. A statistic for adjusting the batting average for consistency, or what we term the Geometric Coefficient in this context, is proposed as an appropriat...
Article
A recent paper has focused awareness on group aggregation procedures in the AHP, showing that geometric mean aggregation violates the desirable social choice axiom of Pareto optimality, We show that this violation can be attributed to the representation used to model the group decision process, thereby questioning the legitimacy of the Pareto optim...
Article
The corporate merger process is modelled as a bargaining game under certainty. The distribution of gains between target and acquiring companies that would be consistent with the Nash-Kalai axioms is determined in principle. An operational version of the resulting game-theoretic model is fitted to empirical results from 24 recent mergers of companie...
