Analysis of demand variability and robustness in strategic transportation planning
… to domiciles, etc. However, the inherent demand variability present on a transportation network, in terms of weekly occurrences of lane volume, results in emergency weekly shipments that deviate from the long-term plan. This leads to a sub-optimal weekly execution, resulting in higher …

An analysis and mitigation of demand variability on external supply chains
… and speed of product launches. The resulting demand variability and shifting operational environment have led to financial and non-financial impacts, such as poor inventory performance and strained supplier relationships. The objective of this research is to identify processes and procedures …

The use of strategic inventory and packaging postponement to address daily demand variability and seasonal demand patterns in a demand flow environment
… that surfaced after a recent implementation of a demand-driven process in their film finishing operation. By select placement of inventory and a judicious prebuild of spools upstream of the packaging operation, Kodak has reduced manufacturing costs, maximized their ability to respond to consumer …

Managing forecast variability in a build-to-order environment
In any production environment, managing demand variability is a delicate balancing act. Firms must constantly weigh potential obsolescence costs of unused inventory (should sales not materialize) against potential expedite costs or lost sales (should demand outpace available inventory). For …

Analysis of supplier involvement in new product development and launch
… their characteristics, such as short life cycle, demand variability, and high investment risk, require responsive, flexible, adaptable supply chains and relevant practices. Those practices need to be properly tailored for specific different types of new products, perceived as a continuum of …

Achieving Cost-effective Supply Chain Agility For The Semiconductor Industry
… is defined as the ability to satisfy customer demands by reacting effectively to changes in market stimuli. Reacting effectively does not mean reacting to every change in supply or demand. Doing so means increasing supply chain variability unnecessarily, which is amplified by the bullwhip …

Delivery optimization for a make to order custom wire mill
… in its production environment to meet customer demand in an effective manner. Specific challenges include poor forecasting abilities, variation in customer demand, long component lead time, and expensive components. For this study, the desired delivery time reduction is to be achieved by …

Toward effective common operating policies for medical items in ongoing humanitarian operations : the science and art of segmentation : a case study
… The major conclusion is that consideration of demand variability as a means to achieve greater item availability is key. The determination of appropriate costs becomes a transparent one for the decision-maker. More generally, this approach facilitates the comparison of various inventory …

The impact of "Never Run Out" policy assured supply chain with dual reorder point expediting
… is involved. Sources of uncertainty include variability in demand from frequent promotions or seasonal effect, variability in order lead time from using low-cost mode of transportation, or lack of information sharing. This project developed an expediting policy with dual reorder points with …

Analysis of the Effect of Ordering Policies for a Manufacturing Cell Transitioning to Lean Production
… the performance of the cell under conditions of demand variability and imperfect supplier performance. The ordering policies evaluated are a periodic-review inventory control policy (s, S) and two kanban policies. The performance of the cell is measured by the flowtime of the product through the …

The impact of SKU and network complexity on inventory levels
… complexity and inventory levels relative to demand for a major fast-moving consumer goods company. For this research complexity is defined as the number of SKUs in a brand and the number of stocking locations for an SKU. We find that while increased complexity does translate into increased …

Characterizing cost and performance of flexibility strategies in autobody manufacturing
Consumer demand is hard to predict in any industry, let alone the automotive industry. Vehicle manufacturers try to produce according to what their customers want, but if these wants change, the company is faced with lots of unsold cars and a huge changeover cost. In order to help fight the …

Assessing Renewable Resource Penetration on Power System Small-Signal Reachability
… supply side. Operational uncertainty, e.g., demand variability, is not new to power systems. However, with the increased penetration of renewable-based generation, operational uncertainty will extend to a significant portion of the supply side, which may have an impact on system dynamic …

Raw material inventory strategy for make-to-order manufacturing
… at maximum capacity or have seasonality in demand. This research proposes a raw material inventory policy evaluation tool that allows a company to understand how certain key performance indicators are affected by various changes in its inventory policy and helps the company devise a …

Optimizing inventories and standardizing planning procedure in a multipart manufacturing system
… on data from the "SAP" system. To estimate the demand variability, we utilize an adjustment method that accounts for the aggregate bias in the forecast. The final optimal solution will reduce the safety stock level by 67% for the supply chain. We also find a nearoptimal solution that is easier …

Tradeoffs in Air Force maintenance : squadron size, inventory policy, and cannibalization
… and reduce cost, yet must deal with large demand variability and must be prepared for wartime surge, cannibalization, a large number of aircraft, and a large inventory of spare parts may be necessary and may even be cost-effective.

Differentiating the hospital supply chain for enhanced performance
… product based on that product's unit cost, demand, variability, physical size, and criticality. The research analyzes demand data from two hospitals and demonstrates that hospital demand can be modeled using a variation of Croston's method for intermittent demand. This fact was used to …

Designing a strategic sourcing process for low volume, high technology products
… further up the supply chain see greater demand variability. As an equipment provider, Axcelis is positioned relatively far up the supply chain and therefore, managing these business cycles is an important initiative. Strategic sourcing helps companies manage the cyclical industry by …
