    No full text
    This paper portrays the development of a concession-investment optimization model for optimizing the winning potential of a concession-bid from the prospective promoters' viewpoints by taking into account imprecise investment parameters. A financial performance measure has been developed to quantify bid-winning potential. Fuzzy set theory is embedded into a genetic algorithm to optimize bid-winning prospects of concession schemes under uncertainty. The fuzzy vertex method accomplishes propagation of uncertainty in cash flows arising from imprecision in estimation of investment parameters. Genetic algorithm solves the optimization routine. The developed model yields global near-optimal solution of bid-winning potential with contributing values of concessionary items: concession length, base price, and equity level under uncertain investment environment. A numerical example demonstrates model capabilities. The model results would help promoters devise a profitable, yet competitive, financial proposal.Griffith Sciences, Griffith School of EngineeringNo Full Tex

    The pursuit of sustainable materials in engineering has led to a growing interest in bio-composites derived from natural fibres. This keynote presentation explores the innovative use of powdered macadamia nutshells - an under-utilised by-product of the food industry - in the development of composite cores and sandwich structures. By processing these nutshells into specific particle sizes and integrating them into a suitable resin matrix, we have fabricated composite cores and sandwich panels reinforced with carbon fabric skins. The resulting materials demonstrate enhanced flexural and shear strength, positioning them as promising alternatives to conventional materials in high-performance sectors such as aerospace and automotive. This research highlights the potential of agricultural wastes like macadamia nutshells to contribute to sustainable manufacturing practices, offering a viable pathway for waste utilisation and the advancement of eco-friendly engineering solutions. Future studies will aim to optimise particle sizes, weight ratios, and assess long-term durability, further unlocking the potential of these novel composite materials

    Optimal coordination of energy sources for microgrid incorporating concepts of locational marginal pricing and energy storage

    Full text link
    This research aims to coordinate energy sources for standalone microgrid (MG), incorporating locational marginal pricing (LMP) and energy storage. Two approaches are suggested for the optimal energy management of MG. First, the energy management of a standalone MG is performed utilising the concept of LMP. The objective is to minimise the average LMP to reduce network congestion and power loss costs. Second, energy management is performed using a dual-stage energy management approach. A BESS model is formulated considering charging and discharging characteristics and utilised in this research for dual-stage energy management. The impact of the battery state of charge (SOC) is assessed in the optimal day-ahead operation. An incremental cost factor is included with battery SOC when calculating the system operating cost. A new binary jellyfish search algorithm (BJSA) is developed to solve energy management problems. The suggested BJSA technique is implemented in solving the optimal energy management of MG considering LMP. The simulations of the suggested approach are conducted on the IEEE 14 and 30-bus test systems. Results show that the BJSA technique is more consistent than the binary particle swarm optimisation (BPSO) technique in determining the optimal solution. In addition, the BJSA technique is employed to solve the dual-stage energy management of MG considering BESS. The proposed approach is simulated on the IEEE 14 and 30-bus systems. Results also show that the BJSA technique is superior to the BPSO technique in minimising the operating cost in real-time economic dispatch (ED). The performance of the BJSA and BPSO techniques is exactly similar to the UC schedule with and without BESS considering the IEEE 30-bus system, like the IEEE 14-bus system. The BJSA technique minimises operating costs by up to 5% over the BPSO technique for the UC schedule with power loss. Operating costs are reduced by up to 5% using the BJSA technique rather than the BPSO technique for real-time ED with BESS. However, the BPSO technique is inconsistent and fails to obtain the same results for the IEEE 30-bus system. Overall, the findings confirm the superiority of the suggested BJSA technique and the suggested optimisation approaches in optimising the energy management of MG

    This presentation illustrates research conducted on the development of elastomeric composites utilizing agricultural waste, specifically macadamia nutshells, and industrial waste, ceramic hollow microspheres, as reinforcement fillers. The research aims to effectively utilize agricultural and industrial waste to produce sustainable materials, aligning with the current focus of researchers on waste management and sustainable material development. In the initial phase of the project, ground macadamia nutshells were employed as natural fillers due to their outstanding mechanical properties such as high strength, low density, and favourable thermal characteristics. Subsequently, ceramic hollow microspheres extracted from fly ash, a byproduct of coal-fired power plants, were utilized as non-natural fillers in the second phase. The fabrication of the composites using rubber involved a modified hand layup method. The weight percentage of the fillers served as the independent variable, and samples were produced with varying weight percentages. These samples underwent various mechanical tests and SEM analysis to investigate their behavior under different loading and texture conditions. The results were analysed to identify the properties of these novel composite materials and to determine further research directions. This research signifies a significant advancement in promoting sustainable practices and materials, opening new avenues in this domain

    Optimizing Concessionary Items' Values for Procuring Privately Financed Infrastructure Projects

    No full text
    To provide reliable and cost-effective infrastructure services to the public, governments around the globe often seek participation from the private sector with an emphasis on their ability to provide private finance. As such, most countries exploit competitive tendering to award Privately Financed Infrastructure (PFI) projects to sponsors representing the private sector. Within the framework of competitive procurement, sponsors not only strive to maximize their potential of winning such ventures at the tendering stage, but they also aspire to achieve a certain level of profit reflecting the risk associated with their investment. Moreover, owing to their limited financial capacity, sponsors must seek external funds from financial institutions (lenders) and, consequently, make their best efforts to maximize the potential of attracting lenders. This challenging process is mainly governed by a project’s concession length, base price (such as initial tariff/toll), and debt-to-equity ratio – collectively known as concessionary items. Owing to multiparty involvement, a state of optimality always reigns in determining the ideal values of concessionary items. Although profitability plays the pivotal role, chasing optimal values of concessionary items thus appears as an intrinsic uphill struggle to potential sponsors. Without resolving multiparty conflicting financial interests, the selected values of concessionary items may not only be suboptimal but may also be erroneous, leading to the sponsor’s failure in winning the bid for procuring the project. An exhaustive review of existing literature reveals that previously developed financial analysis models cannot adequately capture the complexities associated with determining optimal values of concessionary items through evaluating their aggregated impact on PFI project cash flows.Thesis (PhD Doctorate)Doctor of Philosophy (PhD)School of EngineeringScience, Environment, Engineering and TechnologyFull Tex
