Hierarchic change system dynamics supply chain model: impact of demand information sharing on holding cost and downstream project completion

The interrelationships between system components are critical to improving the performance of a complex supply chain system. Thus, any improvement or development can be carried out systemically and comprehensively. complexity coordination grows as number echelons in increases. In practice, becomes more difficult implement with echelons. Through demand information sharing, this research attempts figure how have implications for multi-echelon chains modeling approach. Aggregate Andesite Stone Supply Chain is used an empirical model four Changes dimensions values per ton product each echelon displacement add complexity. Total holding cost not only consideration. timely completion projects downstream also priority. So system's behavior that runs changes over time needs observed. To accommodate complexity, dynamics approach used. This technique could capture fluctuations volatile conditions change sequences. pattern shows sharing andesite aggregate faint, "bullwhip effect" occurs. eliminate effect, reduce up 73.5 % total costs, increase percentage project on chain. These results provide scientific practical understanding although there many obstacles, significantly improve worthwhile applied
