Abstract
This paper has investigated the inventory and financial flows in supply chains, its purpose is to provide a method to optimize this two flows for chain member’s’, Return On Capital(ROC) define as performance index and cash conversion cycle(CCC) equation components which show financial and physical flows are formulated as variables that determine ROC performance. The data of chain members of six selected industries have been extracted and two scenarios were presented. According to the agent- based modeling the behavior of chain members in interaction with the upstream and downstream were simulated by NetLego software. Outputs analyzes are based on tiers of chains. Results of first scenario indicate that if Days Inventory Outstanding (DIO) is reduced in downstream and transferred to upstream of the chain and Days Payment outstanding (DPO) in the upstream shortened, ROC be improved for entire chain, as well as the result of second scenario shows regarding to the reduction of cash conversion cycle through productivity under collaboration of chain members the performance improvement of ROC is remarkable.
