RT Journal Article T1 A polynomial rule for the problem of sharing delay costs in PERT networks A1 Castro Cantalejo, Javier A1 Gómez González, Daniel A1 Tejada Cazorla, Juan Antonio AB In this paper we define the weighted serial cost sharing rule for the cost allocation problem.We apply this new rule to the problem of sharing delay costs in a PERT network. This rule belongs to the Core and is the Weighted Shapley Value for a particular game. Furthermore, we present a characterization of this rule and a polynomial algorithm for its calculation.
