Arborescent Supply Chains: the effect of OUT policies

The objective of this paper is to analyze the impact of the smoothing replenishment rules on a divergent supply chain. To this purpose we simulate a classical four echelon serially- linked supply chain model and an arborescent supply chain model under two scenarios, i.e. classical OUT and smoothing replenishment rule. We show that the divergent supply chain structure always performs worse than the serial supply chain and how smoothing the order pattern may decrease this discrepancy

Information Exchange Supply Chain under inventory inaccuracy: a simulation study

The objective of this paper is to contribute at quantifying the impact of inventory record inaccuracy on operational performance and customer service level in collaborative supply chains. To this purpose we analyse the impact of shrinkage errors in the inventory item recording activity in an “information exchange supply chain”, i.e. a supply chain in which companies share information about market demand and use such information for placing orders to their suppliers. We present the mathematical formulation of such a supply chain model and we conduct a numerical simulation and a sensitivity analysis over different level of errors
