However, dynamic synergy relationships among projects complicate this problem. This study aims at constructing a project portfolio selection and scheduling (PPSS) model while quantifying the dynamic synergetic effects to provide decision support for managing PPSS problems.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>This study develops a mathematical model for PPSS with the objective of maximal project portfolio benefits (PPBs). To make the results align with the strategy, comprehensive PPBs are divided into financial and non-financial aspects based on the balanced scorecard. Then, synergy benefits evolve dynamically in the time horizon, and system dynamics is employed to quantify them. Lastly, a case example is conducted to verify the applicability of the proposed model.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The proposed model is an applicable model for PPSS while incorporating dynamic synergy. It can help project managers obtain the results that which project should be selected and when it should start while achieving optimal PPBs.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>This study complements prior PPSS research in two aspects. First, financial and non-financial PPBs are designed as new criteria for PPSS, making the results follow the strategy. Second, this study illuminates the dynamic characteristic of synergy and quantifies the synergetic effect. The proposed model provides insights into managing a PPSS effectively.<\/jats:p><\/jats:sec>","DOI":"10.1108\/k-04-2023-0694","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T22:41:19Z","timestamp":1699915279000},"page":"996-1026","source":"Crossref","is-referenced-by-count":5,"title":["Project portfolio selection and scheduling incorporating dynamic synergy"],"prefix":"10.1108","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4105-6476","authenticated-orcid":false,"given":"Libiao","family":"Bai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengqin","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yichen","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"140","published-online":{"date-parts":[[2023,11,14]]},"reference":[{"issue":"113757","key":"key2025010612200337000_ref001","first-page":"162","article-title":"A multi objective-BSC model for new product development project portfolio selection","year":"2020","journal-title":"Expert Systems with Applications"},{"issue":"799314","key":"key2025010612200337000_ref002","article-title":"Impact of construction delay-controlling parameters on project schedule: dematel-system dynamics modeling approach","volume":"8","year":"2022","journal-title":"Frontiers in Built Environment"},{"key":"key2025010612200337000_ref003","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.cie.2018.02.025","article-title":"A comprehensive approach for the selection of a portfolio of interdependent projects.
