Robust Inventory Induction under Demand Uncertainty
E-commerce retailers need to meet growing demand and rising customer expectations while efficiently managing operating costs across global supply chains. This thesis addresses the tactical problem of inventory induction under demand uncertainty, which involves determining where the position …

Supply chain planning decisions under demand uncertainty
… planning that incorporates unconstrained demand forecasts has been expected to improve long term corporate profitability. Companies are considering such unconstrained demand forecasts in their decisions on investment in supply chain resources. However, demand forecasts are often associated …

Demand uncertainty and investment in the restaurant industry
… of the housing market, the prolonged economic uncertainty lingering in the U.S. economy has dampened restaurant performance. Economic uncertainty affects consumer sentiment and spending, turning into demand uncertainty. Nevertheless, the highly competitive nature of the restaurant industry does …

Robust Cross-dock Location Model Accounting for Demand Uncertainty
… total network costs. In order to account for uncertainty in demands, a robust optimization model was created based on the initial deterministic one. Robust counterparts were developed for each equation that contained the demand term. The robust model allowed for the creation of a network with …

Managing Demand Uncertainty for Perishable Products Through Omnichannel Grocery
… presents a collection of studies on the value of demand information in a grocery retail setting. Mutually aiming to improve operating outcomes and reduce food waste, the studies tackle the retailer’s daily challenge in deciding replenishment quantities while facing uncertainties in demand. Two …

Strategic last-mile distribution network design under demand uncertainty
We propose quantitative models to incorporate demand uncertainty and physical distribution flexibility into the strategic design of last-mile distribution networks. Last-mile distribution typically constitutes the most expensive part of any global supply chain, and it is becoming increasingly …

Lean principles applied to a supply chain with demand uncertainty
… the importance of leveling the customer demand signal in order to implement a true pull system using Kanbans. On the other hand, this thesis describes the implementation of lean manufacturing tools such as Kanban systems and Heijunka boards in some Kodak operations. This work includes the …

Capacity Investment, Flexibility, and Product Substitution/Complementarity under Demand Uncertainty
… negative price policies) and different demand models. Specifically, we consider a firm that produces two products, which can be substitutable or complementary. The demand of each product is a linear function of the prices of both products (with the relationship depending on the …

Two approaches to buffer management under demand uncertainty : an analytical process
(cont.) boundary and leave more demand uncertainty to the pull part of the system.

The effect of demand uncertainty on planning: the steel industry in Argentina
… the investment decisions in a case with large uncertainty in demand: the steel industry in Argentina. Special emphasis is devoted to the recent history, where a recent shift in economic policy (1976-1981) towards allowing free competition with imported products resulted in a severe crisis for …

The role of demand uncertainty in materials selection : a case study on aluminum recycling
… with substantial recent growth. The increase in demand for aluminum, however, has outpaced the growth of primary aluminum production. One way to meet this shortfall is the use of secondary, or recycled, materials which provides both economic and environmental benefits. The increased use of …

A screening model to explore planning decisions in automotive manufacturing systems under demand uncertainty
… changing due to shifts in macroeconomic, market demand and regulations, which can significantly influence systems' performance. It is often very difficult or prohibitively expensive to change these engineering systems once they are in place. Thus, a critical question is how to design engineering …

Discrete Choice-based Equilibrium Modeling of Supply Chain Network with Conflicting Objectives and Demand Uncertainty
… under conflicting objective decision-making and uncertainty management in a supply chain network. In particular, discrete choice models are introduced into supply chain equilibrium models to bridge the conflicting objective decision-making in supply chains and customer preference. Furthermore, …

Practical Optimisation of District Energy Systems: Representation of Technology Characteristics, Demand Uncertainty, and System Robustness
… to conventional national-scale networks to meet demand in urban areas. Decentralising electricity production reduces distribution losses, while centralising thermal energy production capitalises on economies of scale. Furthermore, geographic proximity facilitates the use of waste heat from …

Robust transportation network design under user equilibrium
… a transportation network in the presence of demand uncertainty, multiple origin-destination pairs and a budget constraint for the overall construction cost, under the behavioral assumption that travelers optimize their own travel costs (i.e., the "user-equilibrium" condition). Under …

Analytical study and cost modeling of secondary aluminum consumption for alloy producers under uncertain demands
… with the explicit considerations of the demand uncertainty compared to the traditional strategy based on point forecast of future demand. The result shows significant economic and environmental benefits by pre-purchasing excess amount of cheaper but dirtier secondary raw materials to …

New applications in Revenue Management
… Then, we study the impact of competition and demand uncertainty on the three agents involved: firms, government, and consumers. This thesis recognizes the need to measure consumers' welfare for multiple items under demand uncertainty. As a result, this thesis builds on existing theory in order …

Capacity and Operational Performance Optimization under External Constraints with Uncertainty
… the significant impacts of globalization, demand uncertainty, competition, and external emissions regulations on firms' profitability, operational performance, and decision-making processes. The models relax common simplifying assumptions (i.e., deterministic lead-times, exogenous emissions …

The influence of just-in-time systems on physical distribution channel performance: an experiment utilizing a dynamic simulation decision support system
… (echelon) within a channel. The reality of uncertainty in the channel's operation and environment suggests that alternative inventory systems (such as JIT) must be evaluated under a range of internal operational uncertainty and external demand uncertainty conditions. This study offers a …
