The configuration of business process families depends on a group of stakeholders' requirements. However, multi-stakeholders' quality requirements and their priorities have been frequently neglected during business process configurations. In this paper, we introduce the collaborative configuration process and define the fuzzy multi-stakeholder evaluation model. Then fuzzy multi-objective collaborative evaluation method is presented to balance stakeholders' quality requirements and their preferences. The fuzzy collaborative evaluation method is divided into two stages, which consider both the important degree of each stakeholder and the weight of each objective.

In this article, a new autoregressive-based online backup scheme for small files (ABBSF) is presented to achieve the goal by enhancing the utilization ratio of bandwidth resource in normal times. ABBSF exploits single transfer pattern and package transfer pattern to deal with small files. ABBSF employs single transfer to send one small file to the backup side periodically, and collects the network situation in this procedure. According to these network performance information, it builds autoregressive-based model for predicting available network bandwidth in the next period. Meanwhile, it provides predictive step length control to make more utilization of predictive model for maintaining low system overheads. On the basis of prediction, ABBSF makes appropriate transfer policy for package transfer. Finally, it employs package transfer to pack several files and sent them to the backup side. Experiments show that ABBSF has a good performance of prediction with relatively low system overheads to make full use of network bandwidth when backup small files.</p></div>","PeriodicalId":35359,"journal":{"name":"Journal of China Universities of Posts and Telecommunications","volume":"20 ","pages":"Pages 40-46"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1005-8885(13)60223-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78371142","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}
