Procuring the management and maintenance of engineering assets are key activities of government, particularly given the importance of these assets for business and society. Despite their importance, the most effective methods for procuring engineering assets are still to be determined due to the complexity inherent in such arrangements. While Complex adaptive systems (CAS) theory has been advocated as a coherent theoretical framework for examining both procurement and engineering assets, considerable challenges remain in operationalizing this framework for government systems. There are thus two challenges: developing an understanding of the complexity and dynamics of procurement systems, together with a practical problem of how to model such systems. This paper outlines CAS theory and suggests ways that it might be operationalized to examine engineering asset procurement.

Recent developments in Voltage Source Converter High Voltage Direct Current (VSC HVDC) systems have increased its range of applications. When a new high voltage AC transmission line is planned and part of it has to be undergrounded, VSC HVDC is a competitive alternative to AC connections. In this paper, the results of two studies are reported. The first study deals with the Beverwijk-Bleiswijk connection in the Netherlands, the second with the Belgian-German interconnector. Both planned connections are located in the highly meshed UCTE grid.

Ongoing financial, environmental and political adjustments, have shifted the role of large international airports. Many airports are expanding from a narrow concentration on operating as transportation centres to becoming economic hubs. By working together, airports and industry sectors can contribute to and facilitate not only economic prosperity, but create social advantage for local and regional areas in new ways. This transformation of the function and orientation of airports has been termed the aerotropolis or airport metropolis, where the airport is recognised as an economic centre with land uses that link local and global markets. This paper contends that the conversion of an airport into a sustainable airport metropolis requires more than just industry clustering and the existence of hard physical infrastructure. Attention must also be directed to the social infrastructure within proximate areas and the maximisation of connectivity flows within and between infrastructure elements. It concludes that the establishment of an interactive and interdependent infrastructure trilogy provides the necessary balance to the airport metropolis to ensure sustainable development. This paper provides the start of an operating framework to integrate and harness the infrastructure trilogy to enable the achievement of optimal and sustainable social and economic advantage from airport cities.

The results of institutional changes in the network-based industries are rather disappointing. One of the reasons for these disappointing results is the strategic behaviour of actors involved. It has turned out to be problematic to combat this behaviour by using traditional arrangements. This paper explores new innovative arrangements to combat strategic behaviour.

Environmental Protection in China is an issue which is gaining attention globally and locally. It seems the most prominent problems lie in the implementation and enforcement of the legislation and regulation, which is set up in a decentralised manner. This means that local governments and Environmental Protection Bureaus are responsible for the actual controls and implementation. The EPBs face several considerable problems in the fulfilling of their tasks. Firstly they generally have very few resources to work with, leading to understaffed bureaus and a lack of knowledgeable workforce. Secondly, the EPBs are dependent on the local governments for a part of their financial resources, which can potentially lead to subjective enforcement. At the same time the EPBs are dependent on the companies in their controls, as controls occur on the basis of invitation only. These problems lead to a controlling body that is impaired in its functioning. It is difficult for the EPBs to fulfil the task they are responsible for, which means that the incentives for environmental protection are low. If this situation remains unchanged the industry is unlikely to make major changes in their process to protect the environment. To ensure environmental protection in China it thus seems necessary to make the first changes in this area, and to enable EPBs to do their work effectively and objectively.

Large infrastructure projects are, as several international studies show (e.g. Wachs 1990, Flyvbjerg et al. 2005), often miscalculated. The same has been shown in a country like Norway (e.g. Odeck 2004, Strand 2004, Osland et al 2007), which has a long tradition for transport planning as well as key role of macro-economics in the planning system. The wrong estimates often imply underestimations of costs in planning and building infrastructure, whereas the positive effects on transport demand are often underestimated in the cases of road infrastructure, but more often overestimated in the case of rail infrastructure (Flyvbjerg et al. op.cit). In this paper we will, firstly, describe and criticize the methodology of the perspective on decision-making as strategic misrepresentations. Secondly we will attempt to provide a constructive development of this analytical approach, both theoretically informed by institutional theory and based on the plausible alternatives that Flyvbjerg et al have promoted in terms of institutional improvement.
正如几项国际研究表明的那样(如Wachs 1990, Flyvbjerg et al. 2005)，大型基础设施项目经常被误判。同样的情况也出现在挪威这样的国家(例如Odeck 2004, Strand 2004, Osland et al . 2007)，挪威有着悠久的交通规划传统以及宏观经济在规划系统中的关键作用。错误的估计往往意味着低估了规划和建设基础设施的成本，而对运输需求的积极影响在道路基础设施的情况下往往被低估，但在铁路基础设施的情况下往往被高估(Flyvbjerg等，op.cit)。在本文中，我们将首先描述和批评作为战略失实陈述的决策视角的方法论。其次，我们将尝试对这一分析方法进行建设性的发展，既要从制度理论出发，又要以Flyvbjerg等人在制度改进方面提出的合理替代方案为基础。

Efficient asset management is a key performance driver for asset-intensive organizations. Achieving high utilization and return on investment on physical assets are central corporate objectives for public and private organisations alike. Current approaches on asset management include the engineering and governance perspectives. The engineering perspective on asset management concentrates on the technical and operational dimensions of asset performance, including utilization, and operation to technical specifications. However, this perspective often ignores organisational-level factors that potentially affect asset performance. By contrast, from a governance perspective, key factors influencing asset management performance include stewardship, accountability and incentive regimes. Symmetrically, the governance view often takes the operational factors for granted. In sum, both perspectives offer valuable but incomplete insights on the management of asset performance: experience demonstrates that an exclusive focus on one or the other may lead to sub-optimal asset and organizational performance. In this paper, we investigate how an integrated approach to asset management can be constructed in the context of vehicle fleets. Vehicle fleets provide a suitable context to investigate these issues as they constitute significant investments, and are observable across a range of asset-intensive industries. Beginning with an analysis of how the asset management process is operated through the asset lifecycle, we identify key engineering and organizational factors influencing asset performance. The relationships between factors are analyzed to provide an integrated fleet asset management approach.

Ports exist by the grace of international trade. In the volatile and uncertain environment of globalization, liberalization, rapidly changing technologies, competition, threats and budgets, this trade is highly unpredictable and investments in port infrastructure therefore highly risky. The aim of this paper is to establish that the uncertainties due to these unexpected developments cannot be actively managed through traditional approach of scenario building for demand forecasting but only through flexible and evolutionary designs.

Engineering asset lifecycle management is information intensive and represents a complex set of activities and processes. These processes generate enormous amount of data, which is captured both electronically and manually, in a variety of formats, shared among an assortment of off the shelf and customized operational and administrative systems, and communicated through a range of sources to an array of business stakeholders. Adoption of information systems for asset management should, therefore, not be treated as technical constructs. In fact, these are social systems, which influence and are influenced by their context. Critical aspects of information systems adoption are to account for organisational culture, social infrastructure, and skills set of employees, and to find the fit between asset lifecycle processes maturity and selected technologies. This paper reports on a case study of a public sector organisation that managing infrastructure assets in one of the largest Australian states. The case indicates that owing to a technologically deterministic view of information system adoption, the promise of an integrated view of asset lifecycle has resulted in a mere historical record of individual activities performed at each stage of lifecycle. The main impediment, among others, has been the fact that technology planning and implementation has been carried out independent of the context, as well as social, organisational, and technical maturity of the organisation.

Cascading failures in electrical power networks often come with disastrous consequences. A variety of schemes for mitigating cascading failures exist, but the vast majority depend upon centralized control architectures. Centralized designs are frequently more susceptible to communications latency and bandwidth limitations and can be vulnerable to random failures and directed attacks. This paper proposes a decentralized approach. We place control agents at each substation in a power network, each of which uses decentralized model predictive control to select emergency control actions. When making decisions the control agents consider not only their own goals, but also the goals of nearby agents. Thus the agents act with reciprocal altruism. Results from simulations of extreme cascading failures within the IEEE 300 bus test network indicate that this approach can dramatically reduce the average size and social cost of large cascading failures. Simulations also show that the bandwidth required for message passing is well within the limits of current technology.
