9、 by each entity is also an important factor because it affects the inventory replenishment process of the upstream entity. The upstream demand may bedistorted and far from the actual demand faced by the downstream entity

11、 quantities, order-up-to levels, and periodic review periods, respectively) are still used in the supply chain environment. However, determination of their control parameters is very difficult. For SCM, all entities in t

20、 belongs to Axsa ¨ ter (2003). The author proposed a technique to approximate optimal reorder points. The model considers holding costs at all locations and backorder costs at retailers. Yokoyama (2002) studied a mu

24、 and to minimize total holding costs of the entire networks. Recently, control parameters of the traditional R,S system for serial supply chains were improved by Xie et al. (2006). The authors propose a two-level supply

25、chain coordination algorithm to adjust the values of R and S, which are regularly determined by the local optimization. Some numerical experimentshave been conducted and it is found that the supply chain performance is i

26、ncreased due to the new values of R and S. Al-Rifai and Rossetti (2007) proposed an efficient heuristic optimization algorithm to determine the con- trol parameters of the s,Q system. Their model is a one-warehouse/multi
