| Abstract: | Fad?lo?lu et al. and Tajbakhsh et al. consider supplier diversification in an EOQ type inventory setting with multiple suppliers and binomial yield and show that working with a single supplier is always optimal. In this short note, we present an alternative and more elegant proof of the optimality of sole sourcing in the EOQ model with general random yield. |
