In this paper, we propose a stochastic model to evaluate QoS (make\u2010span, reliability and cost) of workflow systems based on QWF\u2010net, which extends traditional WF\u2010net by associating tasks with firing\u2010rate, failure\u2010rate and cost\u2010coefficient. Through a case study, we show that our framework is capable of modeling real\u2010world workflow\u2010based application. Also, Monte\u2010carlo simulation in the case study indicates our analytical methods are consistent with simulation. We also present a sensitivity analysis technique to identify QoS bottleneck.The paper concludes with a comparison between our approach and related work.<\/jats:p>","DOI":"10.1155\/2006\/872109","type":"journal-article","created":{"date-parts":[[2015,1,12]],"date-time":"2015-01-12T13:34:21Z","timestamp":1421069661000},"page":"251-265","source":"Crossref","is-referenced-by-count":7,"title":["A Stochastic Model for Workflow QoS Evaluation"],"prefix":"10.1155","volume":"14","author":[{"given":"Yunni","family":"Xia","sequence":"first","affiliation":[]},{"given":"H.P.","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Y.","family":"Huang","sequence":"additional","affiliation":[]},{"given":"L.","family":"Yuan","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2006,12,30]]},"container-title":["Scientific Programming"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2006\/872109.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/2006\/872109","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T02:06:35Z","timestamp":1723082795000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/2006\/872109"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,1]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[2006,1]]}},"alternative-id":["10.1155\/2006\/872109"],"URL":"https:\/\/doi.org\/10.1155\/2006\/872109","archive":["Portico"],"relation":{},"ISSN":["1058-9244","1875-919X"],"issn-type":[{"type":"print","value":"1058-9244"},{"type":"electronic","value":"1875-919X"}],"subject":[],"published":{"date-parts":[[2006,1]]}}}
