In reliability engineering, bath-tub curve is one of the most fundamental concept. From the point of view that bath-tub curve is also applicable in software product, Weibull distribution is introduced for our work. Software products are considered to be the systems composed by multiple intermittently-used components (i. e. function modules). The oparetional probabilities of these components are investigated, and the effects of the oparetional probabilities on reliabilities of the software products are discussed. In application phase of software products, corrective maintenance (revision up) and preventive maintenance (version up) have significant effects on the reliabilities of software products. In this paper, for consideration of these factors, the version up function is introduced to represent the effect of version up, and some numerical examples are discussed.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ソフトウェア工学（SE） "}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"1987-06-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"38(1987-SE-054)","bibliographicVolumeNumber":"1987"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:54:07.569460+00:00","id":22461,"links":{}}
