Chance-constrained programming in activity networks: A critical evaluation
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH, 131(2), 440–458.
author keywords: activity networks; chance-constrained programming
TL;DR:
A classification scheme of stochastic programming and it is confirmed that the chance-constrained programming model for event realization in activity networks (ANs) does not solve the problem of finding a point estimate that satisfies a required confidence level, and is of little help in determining the cumulative distribution function.
