SoS are alliances of independent software- intensive systems combined to offer holistic functionalities as a result of the con- stituents interoperability. SoS engineering involves separately acquiring con- stituents and combining them to form the SoS. Despite the existence of cost pre- diction techniques, predicting SoS acquisition costs at design-time should also include the analysis of different suppliers of constituents, their respective prices and quality. However, known methods cover only two out of these three param- eters. The main contribution of this article is to present the S.O.B. (Save Our Budget) method, a novel simulation-based method to predict, at design-time, the acquisition cost of constituents, while still considering quality attributes and different suppliers. Results of a case study in the Smart Building domain re- vealed that S.O.B. method supports a precise prediction of acquisition cost of constituents to build a SoS for that domain. Furthermore, it also contributes to estimate the cost based on a pre-established quality attribute (functional suit- ability), as well as to support the selection of coalition that exhibits better results through the analysis of cost-benefit ratio.\n\n\n<\/jats:p>","DOI":"10.5753\/isys.2019.779","type":"journal-article","created":{"date-parts":[[2020,6,24]],"date-time":"2020-06-24T11:34:06Z","timestamp":1592998446000},"page":"6-35","source":"Crossref","is-referenced-by-count":2,"title":["S.O.B (Save Our Budget) - A Simulation-Based Method for Prediction of Acquisition Costs of Constituents of a System-of-Systems"],"prefix":"10.5753","volume":"12","author":[{"given":"Valdemar Vicente","family":"Graciano Neto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fl\u00e1vio Eduardo Aoki","family":"Horita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davi","family":"Viana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamad","family":"Kassab","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wallace","family":"Manzano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisa Yumi","family":"Nakagawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3742","published-online":{"date-parts":[[2019,12,20]]},"container-title":["iSys - Brazilian Journal of Information Systems"],"original-title":[],"link":[{"URL":"https:\/\/sol.sbc.org.br\/journals\/index.php\/isys\/article\/download\/779\/734","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/sol.sbc.org.br\/journals\/index.php\/isys\/article\/download\/779\/734","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,30]],"date-time":"2020-09-30T16:06:50Z","timestamp":1601482010000},"score":1,"resource":{"primary":{"URL":"https:\/\/sol.sbc.org.br\/journals\/index.php\/isys\/article\/view\/779"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,20]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,12,20]]}},"URL":"https:\/\/doi.org\/10.5753\/isys.2019.779","relation":{},"ISSN":["1984-2902"],"issn-type":[{"value":"1984-2902","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,12,20]]}}}
