Full textAbstract:
Purpose – This paper aims to develop a fuzzy risk assessment model for construction projects procured with target cost contracts and guaranteed maximum price contracts (TCC/GMP) using the fuzzy synthetic evaluation method, based on an empirical questionnaire survey with relevant industrial practitioners in South Australia. Design/methodology/approach – A total of 34 major risk factors inherent with TCC/GMP contracts were identified through an extensive literature review and a series of structured interviews. A questionnaire survey was then launched to solicit the opinions of industrial practitioners on risk assessment of such risk factors. Findings – The most important 14 key risk factors after the computation of normalised values were selected for undertaking fuzzy evaluation analysis. Five key risk groups (KRGs) were then generated in descending order of importance as: physical risks, lack of experience of contracting parties throughout TCC/GMP procurement process, design risks, contractual risks and delayed payment on contracts. These survey findings also revealed that physical risks may be the major hurdle to the success of TCC/GMP projects in South Australia. Practical implications – Although the fuzzy risk assessment model was developed for those new-build construction projects procured by TCC/GMP contracts in this paper, the same research methodology may be applied to other contracts within the wide spectrum of facilities management or building maintenance services under the target cost-based model. Therefore, the contribution from this paper could be extended to the discipline of facilities management as well. Originality/value – An overall risk index associated with TCC/GMP construction projects and the risk indices of individual KRGs can be generated from the model for reference. An objective and a holistic assessment can be achieved. The model has provided a solid platform to measure, evaluate and reduce the risk levels of TCC/GMP projects based on objective evidence instead of subjective judgements. The research methodology could be replicated in other countries or regions to produce similar models for international comparisons, and the assessment of risk levels for different types of TCC/GMP projects (including new-build or maintenance) worldwide.

Risk is often defined as the degree of uncertainty regarding the future. This general definition of risk can be extended to define different types of risks according to the source of the underlying uncertainty. In this context, the objective of this paper is to mathematically model risks in insurance. The choice of methods and techniques that allow the construction of the model significantly influence the responses obtained. We approach these different issues by modeling risks in three base cases: basic insurance of goods, life insurance, and financial risk insurance. Our findings show that risk modeling allowed us to better measure certain events, but did not allow us to predict them accurately due to a lack of information. Therefore, good modeling of the risk determinants makes it possible to modify the probability associated with the occurrence of a risk. While it cannot predict exactly when a risk will occur, it can help make decisions that will reduce its effects. Keywords: Basic insurance, Life insurance, Mathematical models, Financial risk, Biometric function.

In recent years, the demand for infrastructure has been largely driven by the economic development of many countries. PPP has proved to be an efficient way to draw private capital into public utility construction, where ownership allocation becomes one of the most important clauses to both the government and the private investor. In this paper, we establish mathematical models to analyze the equity allocation problem of PPP projects through a comparison of the models with and without the effects of the theory of “contracts as reference points.” We then derive some important conclusions from the optimal solution of the investment ratio.

Full textAbstract:
Purpose – The purpose of this paper is to evaluate the effectiveness of the statutory adjudication legislation in Western Australia against its stated aims. Design/methodology/approach – The four objectives of the Western Australia Construction Contracts Act 2004 were identified. For each objective a number of criteria has been devised. In total, 22 registered adjudicators were interviewed, representing 28 per cent of all adjudicators in Western Australia. The interviewees were divided into two groups, one with legal background (being both lawyer and adjudicator), the other without (construction professionals). They were asked to evaluate the criteria against a five-point Likert scale in addition to open ended comments. Mann-Whitney U tests were used to examine whether there were significant differences between the two groups. Annual reports of Building Commissioner, database of the WA State Administrative Tribunal and some law cases were also referred to. Findings – It is found that the West Coast Model is fair to both parties, the adjudications are generally completed speedily according to the prescribed timeframe, and they have been conducted in various levels of formalities. Adjudications are very cost effective for larger claims. However, they are not so for smaller claims. The increasing uptake rate shows that adjudication is getting more popular, while the low appeal rate shows that decisions on dismissal are fair. Research limitations/implications – The adjudicators’ opinions are only part of the overall picture and that more research on this topic needs to be done. Originality/value – There have been two distinct legislative models in Australia, commonly known as East Coast Model and West Coast Model. A number of authors have called for a national dual model incorporating both current models. However, it might be too early to discuss the national dual model when there have been very few evaluations on the West Coast Model and among the few there have been problems in the research design. This paper seeks to bridge the gap by evaluating the West Coast Model against its stated aims.

Full textAbstract:
Risk management is one of the topical areas in construction project management research. However, no attempt has been made in the past decades to explore the emerging themes in this area. This paper reviews the research trends in risk management in construction. The bibliometric data of 1635 publications between 1979 and 2022 were extracted from Scopus using a set of keywords. The study used VOSviewer and Gephi to conduct a scientometric analysis on the extracted publications. The review outcome indicates a significant increase in publications on risk management in construction, with about 205 publications recorded between 2021 and 2022 alone. Based on this analysis, it is projected that the next decade will see significant research on risk management, especially as the construction industry moves towards Industry 5.0 with many uncertainties. Further, the most productive countries of risk management studies in construction include China, the United States, the United Kingdom, Australia, and Hong Kong. Emerging key research areas are discussed using network diagrams and clusters. These areas include the processes in risk management, risk analytical models and techniques, sources of risk and uncertainties, effective knowledge-based systems for improved risk management, risk contingency in construction contracts, risk-integrated project planning and scheduling, and stakeholder management. The findings of this study inform researchers on the current progress of risk management studies in construction and highlight possible research directions that can be considered.

Full textAbstract:
Cyber-physical systems require the construction and management of various models to assure their correct, safe, and secure operation. These various models are necessary because of the coupled physical and computational dynamics present in cyber-physical systems. However, to date the different model views of cyber-physical systems are largely related informally, which raises issues with the degree of formal consistency between those various models of requirements, system behavior, and system architecture. We present a category-theoretic framework to make different types of composition explicit in the modeling and analysis of cyber-physical systems, which could assist in verifying the system as a whole. This compositional framework for cyber-physical systems gives rise to unified system models, where system behavior is hierarchically decomposed and related to a system architecture using the systems-as-algebras paradigm. As part of this paradigm, we show that an algebra of (safety) contracts generalizes over the state of the art, providing more uniform mathematical tools for constraining the behavior over a richer set of composite cyber-physical system models, which has the potential of minimizing or eliminating hazardous behavior.

Feasibility studies, planning, pricing and contract management in the construction industry depend mainly on the stability of the economic process where most infrastructure projects require relatively long periods of time to implement them. In a highly inflationary economy where foreign exchange rates constantly change compared to the local currency for long periods that may extend for years. In such an economy, the prices of construction materials vary according to market variables. The methods of pricing items in bids are not feasible for profit and loss accounts and for competition purposes, which leads to significant complications in the management of construction contracts associated with these projects and generates a new case of continuous change unprecedented and has not been resolved even in the global construction contracts of FIDIC. The researcher monitored and collected the inflation values and the exchange rate of Sudanese pound against US dollar as the main currency for a large number of years against the prices of cement for the same years and then statistically studied through a number of statistical analysis programs. Information has been studied over time and then the change in the price of cement versus inflation and the exchange rate and a try to devise a function has been carried out in order to describe that change and express it in a mathematical formula that facilitates reading, analyzing and forecasting. It was found that the change of cement prices is related in a logarithmic function with both inflation and the exchange rate. The independent explanatory variables (exchange rate and inflation rate) were found to be responsible for at least 80% of the changes in the dependent variables (cement prices). The remaining 20% is the impact of other (random) variables not included in the model, and this is an indication of the quality of the documentation of the model. That the variables included in the model is the most influential in the dependent variable of non-included variables. The mathematical models have passed derived economic and standard criterion and have been acceptable statistically and can therefore be relied upon to test any hypotheses are developed.

Full textAbstract:
In the search for benefits to justify transport projects, economic appraisals have increasingly incorporated the valuation of impacts to the wider economy. Computable general equilibrium (CGE) models provide a framework to estimate these impacts by simulating the interactions of urban economies and transport networks. In CGE models, households and firms are represented by microeconomic behavioral functions, and markets adjust according to prices. As markets both inside and outside the transport network are taken into account, a wide variety of measures that can assist in economic appraisals can be extracted. However, urban CGE models are computationally burdensome and require detailed, spatially disaggregate data. This paper discusses the methodology used to develop a database, including an input–output table, for the calibration of an urban CGE model for Sydney, Australia. Official and publicly available data sources were manipulated by using a number of mathematical and statistical techniques to compile a table for 249 regions and 20 sectors across Sydney. Issues, such as determining the appropriate level of aggregation, generating incomplete data, and managing conflicting data, that other input–output table developers may encounter when constructing multiregional tables were addressed in the study. The table entries themselves were mapped and explored, as they provide a useful study of the spatial economy of Sydney. Future work will focus on streamlining the construction of input–output tables and incorporating new data sources.

Full textAbstract:
Abstract The Bromilow Time-Cost model is widely applied for estimating the duration of the construction works. The application of this model requires the estimation of different model’s parameters, which are capturing the economic, social and technological differences in projects’ implementation in different regions/countries. The paper aims to develop a mathematical Time-Cost model to be applied in Romania for the road infrastructure projects, grouped into four categories: highways, road rehabilitation, road modernization and by-pass. The research carried out by the authors has as objective to confirm the existence of the correlation between the project duration and costs, and to propose a procedure to be applied by the public decision authorities in order to estimate the duration of road infrastructure contracts. Tthe estimation of the implementation time was done through three scenarios: optimistic, most likely and pessimistic. The parameters of the Bromilow Time-Cost model and the regression models were identified

Full textAbstract:
The article presents the characteristics and evaluation of the accuracy of estimating the maximum length of the queue of vehicles at signalized intersections by commonly used methods in the world. The analyzes were based on the latest editions of the guidelines in the United States, Canada, Australia, Germany and Poland. In order to carry out accuracy analyzes, traffic tests were carried out at 5 intersection inlets in three different cities in Poland (Bydgoszcz, Torun, Warsaw), covering all phases of vehicle queue formation during individual periods of the signaling cycle (effective red and green signal). In total, the analysis had the results of tests from 81 hours of observation ~23,000 behaviors of vehicle drivers. Based on the analyzes it was found in particular: (1) slight differences in the construction of mathematical models of the considered calculation methods, with the exception of the US HCM model from 2016; (2) small errors in estimating the maximum queue length in unsaturated vehicle flow states (~3-5 vehicles/cycle and ~2-6 vehicles/15 minutes interval); (3) quite large errors in estimating the maximum queue length in saturated and oversaturated vehicle flow states (~11-16 vehicles/cycle and ~15-18 vehicles/15 minutes interval); (4) the main impact on estimation errors in oversaturation traffic states is not taking into account or incorrect determination of the 'so-called' initial queue length of the period preceding the analyzed period.

Full textAbstract:
Cars consume a large amount of energy and material resources, and generate large environmental impacts, through their production, use, and disposal. Some automotive engineers use the life cycle assessment (LCA) method to estimate and understand these environmental impacts arising from their design decisions. The standard LCA method, however, makes some limiting assumptions that exclude changes in parameter values over time. This lack of the temporal dimension leads to uncertainty in estimates, especially for new, high-volume, long-life products, such as cars. The aim of this thesis is to explore the value and challenges of an LCA method that can account for changes in resource consumptions and environmental impacts over time. This thesis modifies the standard LCA method to include some dynamics-the way that the state of a system changes over time in response to internally-generated and externally-imposed forces. A case study considers the technological intervention of replacing steel with lightweight materials in passenger cars in Australia. It considers the dynamics of the wider 'car system' at the level of the product fleet and resource flows, but not at the level of the environmental impacts. This thesis takes a System Dynamics (SD) approach by developing a computational model, a hypothesis of how the system works. The model explains the growth in the Australian car-fleet fuel consumption despite persistent policy intervention by government to decrease fuel consumption, compliance and technology innovation by car manufacturers, and shifts in transportation preferences to non-car modes by travellers. The model also allows the exploration of future scenarios wherein some car manufacturers adopt lightweight-material components and battery-electric powertrains. The computed values are used in spreadsheet calculations of resource flows and environmental impacts. The simulations of the SD model estimate that many resource benefits of lightweight cars take decades to accumulate because steel cars drain out of the fleet slowly. Furthermore, if the population of car travellers continues to grow, then oil depletion and growth in urban density could cause rapid declines in driving intensity and in the size of the petrol car fleet. Low driving intensity makes it difficult to recover the high energy investment in lightweight materials. Finally, the adoption of battery-electric cars enables car travellers to avoid most effects of oil depletion, but traffic congestion could still cause moderate declines in driving intensity and in the car fleet. The inclusion of the dynamics in an LCA study leads to surprising insights-some computational parameters, usually assumed to be constants or fixed functions of time, are considerably nonlinear. The results of the case study suggest that mass-reduction and similar 'efficiency' interventions are less effective than intended because the balancing loops and buffers of the system prevent parameters from operating in critical ranges that shift feedback loop dominance. The considerable investment into such technological interventions could be redirected, for greater effect, to policy interventions that target fuel security and traffic congestion through the behaviour and decision-making of travellers. The superiority of such interventions can be difficult to identify with a linear worldview of complex systems.
