In order to support analyzing bullwhip effect and information sharing in supply chain, this paper proposed a HLA distributed simulation method (WS-HLA) which combined Web Service technologies. This method took each supply chain node as a simulation federal, and wrapped these federals as web services that could be run under controlled by RTI. About the structure of WS-HLA, some key issues of implementation...
In supply chain, the ordering strategy is one of the main reasons leading to Bullwhip Effect which can induce inventory's fluctuations or excessive inventory. In this paper, we set up a simulation model on the retailer' s demand-driven supply chain by virtue of system dynamics, in which we compare the inventory's behavior mode based on different ordering strategy, whose simulation results testify...
This paper establishes a model of the jointly managed inventory (JMI) for iron and steel enterprises based on system dynamics (SD), and simulates the model dynamically with the specific business data. Through a quantitative analysis on the optimization role of the JMI and the bullwhip effect (BE) of supply chain, the paper concludes the feasibility and superiority of the JMI in the supply chain for...
The increase in demand variability as information flows from customers to manufacturers in a supply chain is known as the Bullwhip Effect (BE). Modeling this phenomenon is key in measuring its intensity, aiming at reducing its negative impact on both service and inventory levels in supply chains. This paper proposes a new, more precise mathematical model for quantifying the BE in systems with stochastic...
