These tools work on different views of automation units, which are the basic blocks of manufacturing systems. With this, tool dependent data is generated that relates to automation units involved in the manufacturing process. These tool dependent data sets can be seen as data objects, which are disjunctive in terms of information content. This paper presents a framework, which allows the integration of different design tools. The framework is based on concept of holistic mechatronic objects (HMO), where automation units and related tool dependent data sets are seen as mechatronic objects and related data objects. The framework allows 3D simulation of manufacturing systems on high performance PC clusters using the VRML export of CAD tools. The virtual reality modelling environment interacts with a simulation of the control environment. Since 3D-information is provided and available via the framework, software for automation units can be implemented and tested in parallel to the hardware development, reducing development time","PeriodicalId":241388,"journal":{"name":"2005 IEEE Conference on Emerging Technologies and Factory Automation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126199579","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}

Constraint logic programming (CLP) is an emergent software technology for declarative description and effective solving of combinatorial problems especially in the area of integrated production planning. In that context, the CLP can be considered as a well-suited framework for development of decision-making software supporting small and medium size enterprises in the course of production process planning.

Predictive p-CSMA employed in the MAC sublayer of LonTalk/EIA 709.1 protocol is the heart of communication capability of Lon Work's networks. It is displayed that the behavior of the protocol with no collision detection is quite different from that if the collision detection is enabled. We present the analytical study of evaluation of the saturation window using a Markov model. It is shown that the saturation window does not depend on the number of nodes, but on the structure of the traffic broadcasted to the network. The stationary distribution of backlog stages is exponential and asymmetric with respect to the backlog mean value","PeriodicalId":241388,"journal":{"name":"2005 IEEE Conference on Emerging Technologies and Factory Automation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125993493","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}

Most of the present work on DVS management, however, is based on simplistic assumptions about the hardware characteristics that limit the real applicability of the proposed algorithms. Typical simplifying assumptions consider continuous processor speed, negligible overhead during voltage switching, task execution time linear with frequency, and tasks with equal power consumption. In this work, we enhance the task model to consider some of the real CPU characteristics, and integrate energy-aware algorithms with elastic scheduling to improve control performance of embedded systems running on architectures offering a limited number of operating modes.

While marketing campaigns mostly in the context of industrial Ethernet and modular manufacturing execution systems evoke the impression that integration in automation is a new and revolutionary concept, the opposite is true: integration has always been the ultimate goal of automation. This article presents the historical roots and their evolution up to the present day. Furthermore, it proposes a model describing the three essential aspects of integration, namely, horizontal, vertical, and temporal, and gives an overview of the current technological building blocks such as networks, middleware, and application concepts.

By observing the temperature variations of electric components, we can decide whether the components on the board work well or not. The temperature of the object surface can be measured by infrared cameras. However, the environmental air temperature can have an influence on the temperature of the object surface. In this paper, the data correction algorithm is suggested when the environmental air temperature varies. To correct the infrared data in this paper, the initial temperature or the initial infrared image data is used so that the target source system may not be necessary. The temperature data obtained from infrared detector show nonlinear property depending on the surface temperature. In order to handle this nonlinear property, Taylor series approach is adopted. It is shown that the proposed algorithm can reduce the influence of environmental temperature on the components in the board. The main advantage of this algorithm is only to use the initial temperature of the components on the board rather than using thermal electric coolers as reference temperature","PeriodicalId":241388,"journal":{"name":"2005 IEEE Conference on Emerging Technologies and Factory Automation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116998984","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}
