Therefore there is no longer a simple mapping from an operational view of requirements to the system of systems which enact the required capabilities. This calls into question whether current modelling methods and capability-based procurement paradigms are sufficiently dynamic and flexible to cover future SoS architectures. The paper discusses the attributes required of a modelling approach which attempts to address this problem.","PeriodicalId":388477,"journal":{"name":"2012 7th International Conference on System of Systems Engineering (SoSE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117168137","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}

The air transport liberalization has promoted the air traffic growth with a consequential cost reduction to the passengers and air carriers. In turn, this growth is moving the main airports towards the saturation, affecting the performance and quality of the services provided to the passengers. Some analyses, indeed, foresee that the capacity of the airports, in the management of the aircrafts and passengers, will likely be the bottleneck of the air transport growth. Hence, airport capacity needs to be improved. The common and agreed view for succeeding to this goal moves to the optimization and orchestration of the available resources within the airport. To do that, the interoperability and cooperation among stakeholders, operating in the airport, often with different purposes, has to be rethought, along with the development of novel technological systems enabling and supporting this process. To this aim, the paper proposes a new framework that enabling the information interoperability on the top of classic data interoperability among heterogeneous stakeholders (often legacy systems) operating both in airside and landside area and provides a net-centric orchestration service capable of forecasting and promptly optimizing the choices of the stakeholders with the aim addressed to the airport performance as a whole.","PeriodicalId":388477,"journal":{"name":"2012 7th International Conference on System of Systems Engineering (SoSE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115308823","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}

Such systems are typically made of several road stretches connected to compose a network and, of course, the dynamic behavior of traffic in each stretch influences the state of traffic in the overall network. In this sense a freeway network can be considered and analyzed as a “System of Systems”. A distributed Model Predictive Control Scheme in which clusters of freeway cells are separately regulated is proposed in the paper. Moreover, the definition of an event-triggered scheme is included in the paper as well: in the proposed scheme the control action is not computed at each time instant as in the classical Model Predictive Control framework, but only when the system state fulfils specific conditions,.","PeriodicalId":388477,"journal":{"name":"2012 7th International Conference on System of Systems Engineering (SoSE)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124374923","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}

Significant reduction in number of trips has been achieved by finding proper solutions for all mentioned problems and applying needed modifications that could be listed as changes in temperature transmitter settings, changing the types of them, upgrading Human Machine Interface, addition of new signals to PLC software to be shown in monitoring system and DCS for enhanced trip analysis and also correction of some control system program parts such as determination of First out alarm.

Considering the significant damages that a DGT accident can cause, a DGT routing strategy is to avoid the worst case accident scenario, following a risk-averse behaviour. Game-theory is very useful in this context. Taking into account a DGT flow on a road network and the technologies for vehicle/infrastructure communication which are nowadays available, the overall context can be modelled as a system of systems, where a team of road segments concurs to find an optimal strategy to minimise the maximum risk on the territory. Two problems related to DGT are presented and preliminary formulations, at operational and at real-time level, are described. A solving method based on linear matrix inequalities is shown and first results are shown.","PeriodicalId":388477,"journal":{"name":"2012 7th International Conference on System of Systems Engineering (SoSE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131779453","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}

In recent years, Model Based Systems Engineering has been adopted as a means of moving from a document-centric approach to a model based approach where reusable models can be used to analyse the proposed system. The application of multi-objective optimisation algorithms to generate a set of designs that represent the trade-off between competing system requirements would be highly desirable. In this paper, the authors apply different optimisation strategies, inspired by coevolution, to efficiently generate a set of solutions by identifying and exploiting the structure within the design. The preliminary results show that using the structure inherent in a SysML design has significant benefits in terms of the number of evaluations needed to generate the solutions.","PeriodicalId":388477,"journal":{"name":"2012 7th International Conference on System of Systems Engineering (SoSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129683385","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}
