The influence of positions of customer order decoupling point (CODP) on total cost was analyzed. It is point that total cost changed as the positions of CODP moving with the trend of convex function. At last, the model of supply chain cost optimization was simulated. The results indicate that only when the positions of CODP in the middle reaches of production, the customized production of complex products could be realized with low cost and high efficiency by enterprises.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116047303","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 system-on-chip (SoC) becomes prevalent in the intelligent system applications, the reliability issue of SoC is getting more attention in the design industry while the SoC fabrication enters the very deep submicron technology. In this study, we present a new approach of system bus fault injection in SystemC design platform, which can be used to assist us in performing the failure mode and effects analysis (FMEA) procedure during the SoC design phase. We demonstrate the feasibility of the proposed fault injection mechanism with an experimental ARM-based system.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116980127","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 same algorithm deduced from Lyapunovpsilas stability criterion is given to estimate the stator resistance, which results in the speed estimation error. The results of simulation show that the motor speed is controlled well at very low speeds.

According to a typical structure of carrier tracking loop, this paper introduces the principles of the commonly used devices in carrier tracking, such as four-quadrant frequency discriminator (FQFD) algorithm and the principle of expanded Kalman filter (EKF) algorithm, then analyses the tracking performances of these two algorithms with the input signals by setting the frequency as a constant value, or a step equation, or a simple equation or a quadratic equation of time. Based on these two algorithms, a new hybrid carrier tracking algorithm is designed. The performance of newly hybrid tracking algorithm is simulated and the result demonstrates that it is able to track carriers with different sorts of frequency changing laws, with small tracking errors.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115455960","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}

Incorporating these information, the intent model is determined by a pretreatment and probability method. Finally, the future trajectory can be predicted.
