Optimizing safety stock placement in general network supply chains
The amount of safety stock to hold at each stage in a supply chain is an important problem for a manufacturing company that faces uncertain demand and needs to provide a high level of service to its customers. The amount of stock held should be small to minimize holding and storage costs while …

Reduction of total production cost through the use of safety stock and process improvements
… the system. Next, an analytical approach to set safety stock levels is applied to balance the cost of inventory held with the cost of a shortage. By reducing the variability in the system, inventory levels can be reduced while maintaining the service levels. This process is then repeated at …

Using forecast variability and risk pooling to determine optimal safety stock levels within a supply chain
… be shown that the optimal level of inventory safety stock for these and other motherboards can be significantly reduced by holding them in a format which allows them to be easily and flexibly configured to satisfy demand when a customer order arrives rather than holding the material in a …

Using lead time data to identify cost saving opportunities in an automotive supply chain : inventory safety stock and trucking carrier pool
… to two supply chain and logistics problems: safety stock and transportation fleet sizing, identifying about $10MM of one-time and continuing savings opportunities. In both cases, we similarly are looking at creating a strategic buffer, either in terms of inventory or trailers, to account for …

Strategy for direct to store delivery
… and evaluate the impact on transportation and safety stock when a manufacturer transitions from a 100% DC delivery method to 100% Direct-To-Store (DTS) method. Drawing on the results of a case study on Niagara bottling, a leading private brand water bottle manufacturer in US, the thesis …

Multi-echelon inventory strategies for a retail replenishment business model
… is to ensure consumer-essential products are in-stock at retailers at all times. To achieve this goal, NIKE has developed a forecast-driven, make-to-stock supply chain model which allows retailers to place weekly orders to an on-hand inventory position in a distribution center. The challenge …

Product availability improvement for analytical column supply chain : inventory optimization and lot sizing
… demonstrates the potential of a structured safety stock policy, and an improved lot sizing production policy on the inventory level and service level. The thesis focuses on incorporating demand variability into the factors of determining the safety stock level, and establishing a structured …

Inventory strategies for patented and generic products for a pharmaceutical supply chain
This thesis presents a model to determine safety stock considering the distinct planning parameters for a pharmaceutical company. Traditional parameters such as forecast accuracy, service level requirements and average lead-time are combined with a nontraditional upstream uncertainty parameter …

Strategic inventory management of externally sourced medical devices
… ownership occurs upon receipt. When calculating safety stock, we determined that supply variability should be incorporated into the safety stock formula and extra buffers currently in place should be removed. In addition, a more robust measure of demand variability such as the Root Mean Squared …

Inventory optimization in high volume aerospace supply chains
… This thesis outlines a system for optimal safety stock management in high volume aerospace supply chains. Given such supply chain parameters as component inventory values, procurement and manufacturing lead times, demand distributions, and bills of material, the ideal safety stock locations …

Algorithmic intervention to mitigate inventory and ordering amplification in multi-echelon supply chains
… management and refers to how forecast errors and safety stock builds yield increasing amplitudes in both orders and on-hand inventory positions the further one moves away from a source of order variability. The bullwhip effect is responsible for both excessive strain on real world inventory …

Managing forecast variability in a build-to-order environment
… a wide array of products, Dell does not hold its safety stock in the form of finished goods inventory. Instead, safety stock is held as parts inventory, sitting in supplier-owned supplier logistics centers. As a result, supplier stocking decisions may impact Dell's ability to respond to forecast …

Setting optimal inventory policy for mold spare components in a medical device production facility
… control parameters of reorder quantity, safety stock level and reorder point. Spare component inventory will be categorized by usage rates and their criticality to mold repairs while critical inventory parameters of safety stock, reorder point and reorder quantity are set to ensure a …

Quantifying the impact of customer allocations on supply chain performance
… allocations. A model was built to calculate safety stock using historical allocations data as a demand indicator. Using this model, we simulate how much safety stock would be sufficient to meet expected demand as we reduce the number of allocations groups and pool risk across larger groups of …
