This theory defines the interaction of system variables giving the opportunity of a reliable and fair score as well as objective decision-making with regard to the areas that are susceptible of continuous improvement. This paper utilises the principles of the System Dynamics in order to propose a new method for measuring business excellence and thus contributing to a thorough evaluation of an enterprise which implements a Business Excellence Model. The proposed business excellence system is adopted and applied as the Hellenic National Quality Award scheme. The study only adopts empirical data from the application of the proposed business excellence system due to the early stages of implementation in the market. Future research may use more data to better tune the proposed method. Based on the more accurate analytical results achieved by the proposed model, the Hellenic national authority of managing the Hellenic scheme of business excellence might use the proposed model for measuring business excellence and to drive continuous improvement and competitiveness according to its strategy.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134471699","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}

Non-equi-join predicates can be as simple as an inequality expression between two join relation fields, or as complex as a user-defined function that carries out arbitrary complex comparisons. The nature of non-equi-join calls for predicate evaluation over all possible combinations of tuples in a two-way join. In this paper, we consider the family of fragment and replicate join algorithms that facilitates non-equijoin evaluation and adapt it in a Smart Disk environment. We use Smart Disk as an umbrella term for a variety of different storage devices featuring an embedded processor that may offload data processing from the main CPU. Our approach partially replicates one of the join relations in order to harness all processing capacity in the system. However, partial replication introduces problems with synchronizing concurrent algorithmic steps, load balancing, and selection among different join evaluation alternatives.We use a processing model to avoid performance pitfalls and autonomously select algorithm parameters. Through experimentation we find our proposed algorithms to utilize all system resources and, thus, yield better performance.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128817084","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 MAC delay analysis is performed based on elementary probability theory (conditional probabilities) while avoiding the complex Markov Chain method. A comprehensive study of the MAC delay is presented by providing higher moments of the MAC delay distribution. To this end, we use the Z-transform of the backoff duration. The first moment corresponds to the mean MAC delay, while the second moment corresponds to the Standard Deviation of the MAC delay; the latter depicts the jitter. We also estimate the probability mass function (pmf) of the MAC delay through the Lattice Poisson Algorithm. As far as the queuing delay is concerned, we provide the mean queuing delay by considering a queuing system with one queue per Access Category (AC) per mobile station, with a single server (the wireless medium), common to all mobile stations, and a Markov Modulated Poisson Process as input, that expresses the bursty nature of Internet traffic. The presented analytical model provides results of the mean end-to-end delay for both saturated and non-saturated channel conditions.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132295015","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}
