For assuring the control performance under the heavy traffic on the network, the simulation of DCS is strongly needed. In the case of DCSs for controlling a mechanical plant, the graphical and cooperative simulation between the controller model and the plant model becomes important to verify the sequence of motions of the plant. For this purpose, we propose a systematic object-oriented-based DCS modeling procedure to efficiently and uniformly develop the DCS simulation model. From this procedure, we can describe the formal description of DCS simulation model based on five object-oriented design patterns which describe the structure and behavior of the DCS. We also propose an event chain mechanism between the statechart-based controller model and the graphical plant model. Finally, the cooperative DCS simulation software is developed by using the Java 3D API.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126317645","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}

As explained in [1], clear separation of concerns during application development can drastically increase maintainability, reusability and complexity management. Although existing UML-based approaches for real-time systems development do help speed up software development, they still result in models that are hard to maintain and reuse. This drawback is mainly due to a failure to apply the principles of separating concerns. This paper presents an UML-based method using Aspect Principles and dedicated to the development of real-time embedded systems. It focuses mainly on how suitable separation of concerns may ease reusability and maintainability. Specifically, it depicts how application behavior can be clearly modeled applying separation of control and computation aspects of behavior in UML.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133875300","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, UML currently does not support the modeling of quality of service (QoS) criteria, such as the reliability and accuracy (i.e., quality). A QoS framework provides support to ensure consistency in modeling various qualities of service. It supports a general categorization of different kinds of QoS; including QoS that are fixed at design time as well as ones that are managed dynamically. And it supports the integration of different categories of QoS for the purpose of QoS modeling of system aspects. Frequently the behavior of a system component is functionally correct, but the result it generates is nevertheless unacceptable because the result does not meet some QoS criteria. One way to enhance the capability of the system to deliver results of acceptable quality is to use flexible components that adapt their behavior depending on the resources available and the QoS required.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129995823","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}

Suppose each instance of a method t on replicas of an object x invokes another method u on replicas in a quorum of an object y. Here, the method u is redundantly invoked multiple times on some replicas of the object y. If each instance of the method t issues a method u to its own quorum, more number of replicas are manipulated than the quorum number This is quorum expansion. We discuss a protocol to invoke methods on replicas in a nested manner without the redundant invocation and quorum expansion. We evaluate the protocol on how many replicas are manipulated and requests are issued.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129538980","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}

To deal with such non-determinism's, we have developed a family of proactive resource management algorithms that support benefit-function based, end-to-end QoS management. This paper describes a middleware implementation of these algorithms, called Choir. The Choir middleware allows the user express the task end-to-end timeliness requirements using Jensen's benefit functions. Furthermore, the middleware system can transparently replicate, and possibly migrate the computational subtasks to conquer uncertainties such as workload fluctuations, changes of system resources, so that the system aggregate benefit is maximized. Initial experimental results suggest the effectiveness the Choir middleware.","PeriodicalId":204411,"journal":{"name":"Sixth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing, 2003.","volume":"327 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133291944","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}
