    An EOQ model with multiple suppliers and random capacity
    (2006) Erdem, A. S.; Fadıloğlu, M. M.; Özekici, S.
    We consider an EOQ model with multiple suppliers that have random capacities, which leads to uncertain yield in orders. A given order is fully received from a supplier if the order quantity is less than the supplier's capacity; otherwise, the quantity received is equal to the available capacity. The optimal order quantities for the suppliers can be obtained as the unique solution of an implicit set of equations in which the expected unsatisfied order is the same for each supplier. Further characterizations and properties are obtained for the uniform and exponential capacity cases with discussions on the issues related to diversification among suppliers.

    Supplier diversification under binomial yield
    (Elsevier, 2008) Fadıloǧlu, M. M.; Berk, E.; Gürbüz, M. Ç.
    We consider supplier diversification in an EOQ type inventory setting with multiple suppliers and binomial yields. We characterize the optimal policy for the model and show that, in this case, it does not pay to diversify, in contrast to previous results in the random yield literature.
