An online stochastic algorithm for a dynamic nurse scheduling problem
European Journal of Operational Research(2020)
摘要
•The algorithm ranked second at the second international nurse rostering competition.•The approach combines online optimization and the sample average approximation.•The rostering problem is solved with a branch-and-price algorithm.•The code of the implementation is open source and available in a public repository.
