This paper presents a methodology by using a fuzzy Bayesian network to assess the project portfolio resource risk, determine critical resource risk factors, and propose risk-reduction strategies. In this method, the project portfolio resource risk factors are first identified by taking project interdependency into consideration, and then the Bayesian network model is developed to analyze the risk level of the identified risk factors in which expert judgments and fuzzy set theory are integrated to determine the probabilities of all risk factors to deal with incomplete risk data and information. To reduce the subjectivity of expert judgments, the expert weights are determined by combining experts\u2019 background and reliability degree of expert judgments. A numerical analysis is used to demonstrate the application of the proposed methodology. The results show that project portfolio resource risks can be analyzed effectively and efficiently. Furthermore, \u201cpoor communication and cooperation among projects,\u201d \u201ccapital difficulty,\u201d and \u201clack of sharing technology among projects\u201d are considered the leading factors of the project portfolio resource risk. Risk-reduction strategic decisions based on the results of risk assessment can be made, which provide project managers with a useful method or tool to manage project risks.<\/jats:p>","DOI":"10.1155\/2020\/5410978","type":"journal-article","created":{"date-parts":[[2020,11,5]],"date-time":"2020-11-05T19:35:06Z","timestamp":1604604906000},"page":"1-21","source":"Crossref","is-referenced-by-count":24,"title":["Project Portfolio Resource Risk Assessment considering Project Interdependency by the Fuzzy Bayesian Network"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4105-6476","authenticated-orcid":true,"given":"Libiao","family":"Bai","sequence":"first","affiliation":[{"name":"School of Economics and Management, Chang\u2019an University, Xi\u2019an, Shaanxi 710064, China"},{"name":"Research Center for Green Engineering and Sustainable Development, Chang\u2019an University, Middle-section of Nan\u2019er Huan Road, Xi\u2019an 710064, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8063-899X","authenticated-orcid":true,"given":"Kaimin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Chang\u2019an University, Xi\u2019an, Shaanxi 710064, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8047-9474","authenticated-orcid":true,"given":"Huijing","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Chang\u2019an University, Xi\u2019an, Shaanxi 710064, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1069-7492","authenticated-orcid":true,"given":"Min","family":"An","sequence":"additional","affiliation":[{"name":"School of Science, Engineering and Environment, University of Salford, Manchester M5 4WT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4003-9359","authenticated-orcid":true,"given":"Xiao","family":"Han","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Chang\u2019an University, Xi\u2019an, Shaanxi 710064, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","volume-title":"A Guide To The Project Management Body of Knowledge (PMBOK\u00ae Guide)","author":"Project Management Institute","year":"2013","edition":"5th"},{"key":"2","article-title":"Modeling and simulation of project management through the PMBOK D standard using complex networks","volume":"2017","author":"L.
