Space mechanisms requirements specifications often are driven by domain specific features, with many significant uncertainties, and requirements conflicts due to the lack of a holistic perspective. Specific domain simulations are run repeatedly under the given conditions. Such a process is highly inefficient for a company that either writes a requirements specification (manages subcontractors) or designs space mechanisms itself. A general purpose modeling method is proposed to accompany domain specific simulation methods. The resulting framework is proposed to be applied to high precision mechanisms of scientific space missions. Survey of the stakeholders and comparison of methodologies during the conceptual identification of the framework foster an object oriented model-based system engineering methodology and the general purpose SysML modeling languages as the basis for the general purpose modeling part of the framework. The domain specific simulation part is based on the implementation of existing tools under the overall supervision of the general purpose models.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"515 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116213803","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}

From an engineering viewpoint, the classical, centralized approach of system design has obvious limitations in flexibility regarding later reconfigurations and layout changes during system operation. Moreover, a centralized control strategy is limited in terms of energy efficiency. Therefore, distributed schemes relying on single room controllers rather than a centralized HVAC controller are desirable. Such a scalable system setup will also facilitate engineering and re-engineering, e.g., by using a scalable function block approach. Accordingly, the actual control strategy has to rely on model-based predictive control implemented in the individual room controllers in a distributed manner. As such controllers are resource-limited devices, the models should be simple and computationally efficient, yet sufficiently accurate to represent the thermal behavior of the room together with its surroundings. This paper presents an analysis of various room models and proposes a minimum-complexity model. Simulation-based comparison with the state of the art demonstrate no significant loss of accuracy while reducing the implementation effort by 47 percent.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116323432","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 SoS combines an Unmanned autonomous Aerial System (UAS) with an Unattended Ground Sensor (UGS) SoS in order to provide enhanced situation awareness to the users. A simple mini Unmanned Aerial Vehicle (UAV) with an autopilot capable of waypoint navigation is equipped with additional hardware to become a UAS and is integrated with an existing UGS network, forming a System of Systems of heterogeneous systems. The systems in the resulting SoS are autonomous and they offer the generated information via a subscription based service architecture. The SoS described in the paper offers its detection and identification capabilities as services to external entities. The UGS nodes autonomously detect objects and phenomena of interest (based on information requests received from external entities) and by building up collective situation awareness they are able to classify the detected objects, involving the UAS in image acquisition if an object of interest has been classified. The data collected by the SoS is combined and delivered to the external entity that made the information request. The paper describes the creation of the UAS, its integration with an existing SoS and the evaluation of the performance of the resulting SoS.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130223297","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}

Models are abstractions, since they are not the real physical parts, but a data representation of then in a computer. As such, it is tempting to establish a methodology and a system in which models can be shared among projects. When an engineer creates new models of components in a new project, her past experience in making similar components, as well as that of her colleagues, can be easily reused since no physical limitations get in the way. Models in our case are actually mathematical equations. Yet, the wide variety of design tools makes it difficult to take an existing component model created in one tool and reuse it in another. This problem is often classified as `tools interoperability' where models need to be shared among tools. Scenarios which give rise to such needs occur when teams collaborate on the same project, but belong to different organizations or different disciplines. Yet, the advantage of reuse is very obvious and presents a certain use case for interoperability. Our scenario would be a systems engineering organization that needs to support reuse in its design work. Our use-case would be different than the problem of product-lines. There, components are designed for ease of customization to match different, but similar requirements, while sharing one source that can be varied towards multiple different outcomes. Here, reuse can be applied too over a design for a product-line. Internet of Things (IoT) and design patterns will be looked at as well to be proper candidates to benefit from the approach to reuse as will be presented in this paper.","PeriodicalId":251318,"journal":{"name":"2015 Annual IEEE Systems Conference (SysCon) Proceedings","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125590544","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}
