A better understanding of the risk attitudes of system operators and maintainers may be useful in understanding potential impacts the system operators and maintainers have on operational availability. This article contributes to the literature a method that synthesizes the concepts of system reliability, and operator and maintainer risk attitudes to provide insight into the effect that risk attitudes of systems operators and maintainers have on system operational availability. The method consists of four steps providing the engineer with a risk-attitude-adjusted insight into the system\u2019s potential operational availability. Systems engineers may use the method to iterate a system\u2019s design or maintenance concept to improve expected operational availability. If it is deemed necessary to redesign a system, systems engineers will likely choose new system components and\/or alter their configuration; however, redesign is not limited to physical alteration of the system. Several other options may be more practical depending the system\u2019s stage in the life cycle to address low risk-adjusted operational availability such as changes to maintenance programs and system supportability rather than on component and system reliability. A simple representative example implementation is provided to demonstrate the method and discussion of the potential implications for Navy ship availability are discussed. Potential future work is also discussed.<\/jats:p>","DOI":"10.3390\/systems8030026","type":"journal-article","created":{"date-parts":[[2020,8,4]],"date-time":"2020-08-04T10:45:17Z","timestamp":1596537917000},"page":"26","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Method to Account for Personnel Risk Attitudes in System Design and Maintenance Activity Development"],"prefix":"10.3390","volume":"8","author":[{"given":"Benjamin W.","family":"Rathwell","sequence":"first","affiliation":[{"name":"Department of Systems Engineering, Naval Postgraduate School, Monterey, CA 93943, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9910-371X","authenticated-orcid":false,"given":"Douglas L.","family":"Van Bossuyt","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering, Naval Postgraduate School, Monterey, CA 93943, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Pollman","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering, Naval Postgraduate School, Monterey, CA 93943, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"III","given":"Joseph","family":"Sweeney","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering, Naval Postgraduate School, Monterey, CA 93943, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1016\/S0925-5273(01)00156-6","article-title":"A framework for maintenance concept development","volume":"77","author":"Waeyenbergh","year":"2002","journal-title":"Int.
