Although for top 10 risk reporting a periodic, non-continuous approach is useful, for physical asset risk management it has its limitations. Why does periodic risk management not work in asset orientated companies? Which requirements are needed for asset risk management? How should asset risk management look like to comply with these requirements? At Essent Network we have explored these questions and determined, based on practical experience that for asset risk management the asset risk register is the most important element. In such a register a continuous approach, with detailed risk descriptions works best.","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133018019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This dilemma is especially manifest in the management of the performance benchmarks time, cost, scope and quality. Administrators hold to pre-established benchmarks, while project managers have an interest in relaxing them, in order to be able to realize the project. When these two contradictory interests are not reconsolidated, either the benchmarks are not met, or they will be traded off in an uncontrolled way, which even may lead to project failure. This management trap is best to be avoided when designing the contract between client and contractors and the drawing up of the terms of reference. Due to the complexity that characterizes a lot of public projects, this is not always possible. With RandstadRail as example, we will show in this paper what problems may occur in these situations and how they can be dealt with.","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133612793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By representing processes as distinct instances of technologies, it is possible to have an infrastructure that self-assembles as each owner of any technology must trade with other owners of technologies to satisfy the individual input and output demands. The ABM is used to generate and simulate the complex bio-electricity system evolution, while an LCA is used to analyze it at each simulation tick by presenting the results of calculating life cycle environmental performance. Thereby, a methodology has been created that allows for a type of dynamic LCA, which provides ecological information for decision-making. Foundations, implementation and application of this new methodology for dynamic LCA will be addressed and themes for further research will be discussed.","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114231007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the novel applications of scheduling models is their usage for in-site utility management of a process plant. It is very common for huge process plants to provide their utility by themselves; therefore, they shall make decision on utility supply and demand simultaneously. This approach can be extended to other similar systems such as distributed generation networks. In fact, it is possible to consider a DG unit as an autonomous system which is responsible for its energy (heat and power) supply and demand. Of course, for achieving its reliability and dispatchability goals, it would extend its connections to external parties; this fact can be a basis for evolution of a DG network. This paper describes the concept of application of scheduling models for utility management of process plants and aims at extending those ideas to demand management of a DG unit. In addition, the effects of such behavior on energy sharing between DG units and the consequent effects on the performance of DG network are discussed.","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117116860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congestion, safety risks and differing forms of environmental degradation persist, despite all policy efforts to counter those. The mobility system seems to have reached a state of lock-in, asking for changes of a similarly structural nature: A mobility transition. Transitions involve changes in many subsystems. This paper highlights the role of the traffic management subsystem. Traffic management is concerned with guidance of vehicles over infrastructure, optimizing traffic flow and safety. It accommodates traffic, and in that sense could reinforce system lock-in. The `autopoietic' evolution of traffic management does not amount to mere system reproduction, however. Traffic management has come to acknowledge that interjurisdictional governance of networks is indispensible. This holistic approach could become the backbone of a mobility transition trajectory.","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116124587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results from the ASTRA model show that a transition to hydrogen transport fuels would have an increase in GDP, employment and investment; and growth in a number of sectors (electronic, chemical, mechanical, automotive) associated with FCV technology. A hydrogen diffusion model shows that in a few years after 2040 all cars in Germany could be hydrogen driven cars. Fast build up of a network of at least 500 filling stations (in urban areas and at highways) is very important for the market acceptance of hydrogen vehicles and compared with subsidies for vehicles and fuel the necessary investments are very small. For fuel infrastructure: (1) Only a total amount of approx. 200 million Euros are necessary for infrastructure build up in urban areas (2) Additional support is needed for installation of hydrogen filing stations at highways (approx. 100 million Euros).","PeriodicalId":207041,"journal":{"name":"2008 First International Conference on Infrastructure Systems and Services: Building Networks for a Brighter Future (INFRA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128777990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, barriers like lack of airspace regulations, airworthiness, safety, and standards applying to manned systems still remain the chief issue to address. Various initiatives are brought to life to support the creation and expansion of a civil/commercial UAV market, aiming integrated unmanned aerial systems (UAS) to National Airspace System (NAS).
