| Sumario: | The aim of this paper is to deepen the analysis of Evans and Naim (1) on the relationship between the limited production capacity and the Bullwhip effect, and updated according to recent configurations of collaborative supply chains. We analyze three supply chains with limited production capacity, the traditional supply chain studied by Evans and Naim (1), a chain EPOS (Point of Sales Exchange) and a synchronized chain. Adopting a metrics system to assess the benefits of the nodes in the chain measured in terms of stability of the order, stability of the inventories, and robustness of the system, and in terms of benefits to the client, measured in terms of backlog.The results suggest (I) the saturation of demand in a traditional string can generate a "double risk": to meet a market demand and thus distorted oversized to a significantly higher cost of production. (II) the negative effects of limited capacity are significantly reduced in collaborative supply chains.Key Words: Amplification of demand; multi-step, performance metrics, up-to- Order; Periodic review; division of information, rules of order; outsourcing, simulation, differential equations, single-step Euler-Cauchy.
