evaluated the benefits of
information sharing in a supply chain, i.e., inventory reduction and
cost savings. Sahin and Robinson [6] showed that the overall cost in a
supply chain could be reduced by the information sharing with which
the decisions for inventory replenishment and delivery planning are
coordinated. In addition to that, Ryu et al. [7] presented methods for
information sharing in supply chains and analyzed the effect on the
performance of the supply chains in terms of throughput, inventory
and service levels
