One of the key requirements to build sense-and-respond systems is to accurately capture and model the dynamical behavior of business metrics, a.k.a. key performance indicators (KPI). System dynamics (SD) models and the runtime engines provide means to understand both key performance indicators and the dynamic behaviors (e.g. causality) among them. In this paper, we present a system dynamics model based upon a scenario from supply chain management domain. Our purpose is to demonstrate an alternative approach of building sense-and-respond systems. Specifically, we use system dynamics to formally define the KPIs of both the retail inventory and the supplier backlog. Additionally, we introduce objective functions and control variables as the optimization elements being part of the system dynamics formalism. Therefore, the decision (e.g. the order size from manufacturer to suppliers) would correspond to the optimal solution of the system with respect to the defined objective. These concepts will be explained through scenarios. The enabling reference architecture and deployment method using system dynamics are also presented in this paper. After the system dynamics models and corresponding components are deployed to the field, the whole system will manifest the sense-and-respond behavior in a dynamical fashion","PeriodicalId":433885,"journal":{"name":"IEEE International Conference on E-Commerce Technology for Dynamic E-Business","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129037071","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 solution to a hard puzzle is divided into two parts, and the P (prover) provides one of them according to the V (verifier) 's random bit. The eavesdropper cannot obtain any useful knowledge about the P (prover) 's identity during the process of authentication. No adversary in this protocol can cheat each other or get the privacy of each other. The security of this protocol relies on the discrete logarithm problem on conic over finite fields. Compared with those identification protocols implemented on elliptic, these kinds of identification protocols implemented on conic can be designed and implemented easier. Corresponding to the simple version, a parallel version is presented subsequently. The characteristic of ZKp and security of the simple version is proved. The trait of our identification protocol is given. We also analyzed the \"soundness \", the \"completeness \", before analyzed the amount of computation in the protocol. A simple solution considering ttimeout is proposed to prevent a potential leak of our protocol. Some problems need to be solved in the future is brought forward at the end of this paper","PeriodicalId":433885,"journal":{"name":"IEEE International Conference on E-Commerce Technology for Dynamic E-Business","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129195353","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 this paper, we propose a prototype P2P application providing a view-based query processing mechanism in P2P environments, which is named as PeerView. A large number of peers may work under a collaborative and self-organizing scheme to answer their common queries or sub-queries. Given the workload and storage of each peer, some certain peers establish and maintain the views via a cost-based and negotiating way. When processing queries, the peers can first retrieve data from views locally or on nearby peers, instead of from the remote sources. Thus network traffic can be reduced sharply and consequently query-processing efficiency can be boosted significantly","PeriodicalId":433885,"journal":{"name":"IEEE International Conference on E-Commerce Technology for Dynamic E-Business","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134242186","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}

First, it is object-oriented, and thereby supports attribute-level data query.

In this paper, we present Granary's architecture, as well as some of its significant components that are designed in adherence to these two goals, including the node-collection protocol PeerWindow, the routing infrastructure Tourist, and the object-index management algorithm PB-link Tree.

The critical challenge in the deployment is that many technical and nontechnical factors have to be taken into account, such as performance, reliability, utilization, operating cost, incomes, and so on. Since the factors change continuously, some deployed services may have to be redeployed for guaranteeing their functionalities and qualities. This position paper presents an approach to the deployment and redeployment of grid services based on software architecture models. In this approach, all services in a grid consist in a software architecture, which represents the services, their relationships and other factors in a global, understandable and easy-to-use way. To demonstrate the approach, a visual tool for deploying services onto a set of popular grid infrastructures, including J2EE application servers and BPEL engines, with the help of software architectures is developed","PeriodicalId":433885,"journal":{"name":"IEEE International Conference on E-Commerce Technology for Dynamic E-Business","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131738513","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}

But, the approaches work out well only when both the source and the target databases have approximately the same content. Moreover, if some concepts of source do not have the counterpart fields in the target then the mapping will lose the concepts.
