Abstract:
Pooling Lead-time risk by splitting replenishment orders simultaneously among multiple suppliers is a sourcing policy that has attracted the attention of academic researchers for some years. While they consider many different assumptions in their models, they don’t pay attention to deterioration items in order splitting models. In this thesis, we have considered order splitting policy about products with constant deteriorating rate and developed two inventory models. In the first model, it is assumed that the whole requirement supply from only one source, whereas in the second two suppliers are accessible. Then after determining the optimal policy, by numerical search and use of MAPLE software, sensitivity analysis shows some managerial insights. Finally more promising directions are suggested for future researches.
