Abstract

The objective of this paper is to model and simulate a non-echelon supply chain consisting of five levels (customer, retailer, wholesaler, distributor and factory), utilizing a system dynamic approach with Berkeley Madonna software, with the main goal of showing the typical "bullwhip effect" and to find some effective solutions to its destructive effects. In section 1, a brief introduction regarding the reference context and the use of system dynamics in supply chain management is proposed, together with the objectives of the paper. The utilized research methodology and the system dynamics model developed utilizing the Berkeley Madonna software are showed in section 2; some assumptions and simplifications are highlighted. In section 3 obtained results are showed, together with some highlights on the optimization phase (that will be presented in a following work); finally, in section 4, conclusions and recommendations are presented.
