In this case, the diagnosis is usually carried out for each regime for better accuracy. However, the problem is that different results can be derived from each regime and they can conflict with each other, which may invalidate the performance of fault diagnosis. To address this challenge, a methodology for selecting the most reliable one among the different diagnostic results is proposed, which combines the Bayesian network (BN) and the information value (IV). The BN is trained for each regime and a conditional probability table is obtained for probabilistic fault diagnosis. The IV is then employed to evaluate the value of several diagnostic results. The proposed approach is applied to the fault diagnosis of a train door system and its effectiveness is proven.<\/jats:p>","DOI":"10.3390\/s20143952","type":"journal-article","created":{"date-parts":[[2020,7,16]],"date-time":"2020-07-16T10:54:46Z","timestamp":1594896886000},"page":"3952","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Information Value-Based Fault Diagnosis of Train Door System under Multiple Operating Conditions"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1205-7736","authenticated-orcid":false,"given":"Seokgoo","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Aerospace &amp; Mechanical Engineering, Korea Aerospace University, Goyang-City 10540, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0221-9749","authenticated-orcid":false,"given":"Nam Ho","family":"Kim","sequence":"additional","affiliation":[{"name":"Mechanical &amp; Aerospace Engineering, University of Florida, Gainesville, FL 32611, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joo-Ho","family":"Choi","sequence":"additional","affiliation":[{"name":"School of Aerospace &amp; Mechanical Engineering, Korea Aerospace University, Goyang-City 10540, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"314","DOI":"10.1016\/j.ymssp.2013.06.004","article-title":"Prognostics and health management design for rotary machinery systems\u2014Reviews, methodology and applications","volume":"42","author":"Lee","year":"2014","journal-title":"Mech.
