Further managerial implications have been derived from the results. Inventory accumulated between two inter-dependent operations as a buffer against breakdowns or unevenness in machine production rates, thus reducing the. Therefore, seasonal supply chain managers are strongly recommended to adopt the smoothing replenishment rules. Also known as safety stock or decoupling stock refers to inventory thats setaside as a safety net to mitigate the risk of a complete halt in production if one. In addition, the sensitivity analysis reveals that employing the smoothing replenishment rules reduces the impact of the demand parameters and the poor selection of the forecasting parameters on the ordering and inventory stability. ![]() ![]() The results show that the smoothing OUT replenishment rule is superior to the traditional OUT, in terms of the bullwhip effect, inventory variance ratio and average fill rate, especially when the seasonal cycle is small. A simulation study has been conducted to evaluate and compare the smoothing OUT with the traditional OUT (no smoothing), both integrated with the Holt-Winters (HW) forecasting method, in a four-echelon supply chain experiences seasonal demand modified by random variation. This research addresses this gap by investigating the impact of the smoothing OUT on the seasonal supply chain performances. Although several studies have evaluated these smoothing rules with respect to several demand processes, focusing mainly on the smoothing order-up-to (OUT) replenishment rule, less attention has been devoted to investigate their effectiveness in seasonal supply chains. Smoothing inventory decision rules have been recognized as the most powerful approach to counteract the bullwhip effect. ![]() A major cause of supply chain deficiencies is the bullwhip effect, which implies that demand variability amplifies as one moves upstream in supply chains.
