Project risk allocation through contingent cost allocation

Sharing delay costs in stochastic scheduling problems with delays

“…To the best of our knowledge, these problems have not been treated in literature, although Castro et al (2014) considered the problem of allocating slacks in a stochastic PERT network, 1 which is a related but different problem. Tanimoto et al (2000) introduced a variation of the Shapley value for stochastic cost games, their model being an alternative to the stochastic cooperative games in Suijs et al (1999). These two papers deal with general TU-games (not with the particular class we are considering in this paper) and, though they might have some connections with our approach, they are concerned with the different problem of how to allocate the risk according to the risk acceptance level for each player in a general cooperative game whose characteristic function is stochastic.…”
