We investigate two main sources of information inaccuracies in demand information sharing along the supply chain. Firstly, we perform a systematic literature review on inaccuracy in demand information sharing and its impact on supply chain dynamics. Secondly, we model several SC settings using system dynamics and assess the impact of such information inaccuracies on SC performance. More specifically, we study the impact of four factors using three SC dynamic performance indicators. The results suggest that demand error has a negative impact (...) on SC performance, which is exacerbated by the magnitude of the error and by low demand variability scenarios. In contrast, demand delay produces a nonlinear behavior in the supply chain response, being influenced by the supply chain configuration. (shrink)
