The Role of Correlations Between Activity Durations in Project Schedule Risk Analysis Pajares Gutiérrez, Javier Acebes Senovilla, Fernando Martín Cruz, Natalia Gúdel, Ricardo Producción Científica This paper analyses the impact of correlations between activity durations on project uncertainty and risk sensitivity indexes using Monte Carlo simulation. Results show that correlations have little effect on expected project duration but significantly affect variance and sensitivity measures, especially cruciality (CrI) and SSI, while criticality (CI) remains relatively stable. The effects are strongly moderated by network topology, particularly Project Tightness (PT), which emerges as a key factor explaining the magnitude of these changes. 2026-04-21T17:34:13Z 2026-04-21T17:34:13Z 2026-04 info:eu-repo/semantics/article Proceedings of PMS2026, 2026, pp. 88–91. https://uvadoc.uva.es/handle/10324/84254 88 91 Proceedings of PMS2026, Toulouse (France) spa https://pms2026.sciencesconf.org/data/book_pms2026_en.pdf info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional SI
