摘要：We consider a manufacturer without any frozen periods in production schedules so that it can dynamically update the schedules as the demand forecast evolves over time until the realization of actual demand. The manufacturer has a fixed production capacity in each production period, which impacts the time to start production as well as the production schedules. We develop a dynamic optimization model to analyze the optimal production schedules under capacity constraint and demand-forecast updat...

摘要：This study examines the tradeoffs in sourcing and sales strategies (i.e., upstream and downstream supply chain strategies) by considering them as components of an integral end-to-end supply chain strategy. We evaluate four end-to-end supply chain strategies under various scenarios using a newsvendor model, and compare the model's predictions against the prescriptions in Fisher's () framework, which recommends cost-efficient supply chains for functional products and responsive supply chains for...

摘要：In this article, we study the electricity time-of-use (TOU) tariff for an electricity company with stochastic demand. The electricity company offers the flat rate (FR) and TOU tariffs to customers. Under the FR tariff, the customer pays a flat price for electricity consumption in both the peak and non-peak periods. Under the TOU tariff, the customer pays a high price for electricity consumption in the peak period and a low price for electricity consumption in the non-peak period. The electrici...

摘要：Discrete-choice models are widely used to model consumer purchase behavior in assortment optimization and revenue management. In many applications, each customer segment is associated with a consideration set that represents the set of products that customers in this segment consider for purchase. The firm has to make a decision on what assortment to offer at each point in time without the ability to identify the customer's segment. A linear program called the Choice-based Deterministic Linear...

摘要：Brand commitment and the risk of product failure play an important role in the timing of upgrades for a durable product in the presence of stochastic technology advancements. Higher brand commitment makes a firm less vulnerable to sales erosion in an incumbent product due to a technology lag. However, the firm is more susceptible to profit loss from the risk of a failed product. We show that under these circumstances, a firm's optimal upgrade strategy is characterized by a threshold policy bas...

摘要：In the automotive industry, many firms source key components from different suppliers, even though the components may function interdependently. In this study, we investigate how component level interdependence impacts quality performance and analyze how various operational factors moderate this relation. We synthesize information from several case studies to model the quality challenges faced by an automotive firm. For several sub-assemblies that go into its products, the firm sourced key com...

摘要：Discretionary commonality is a form of operational flexibility used in multi-product manufacturing environments. Consider a case where a firm produces and sells two products. Without discretionary commonality, each product is made through a unique combination of input and production capacity. With discretionary commonality, one of the inputs could be used for producing both products, and one of the production capacities could be used to process different inputs for producing one of the product...

摘要：Drug shortages have been a major challenge facing the US pharmaceutical industry and government in recent years. Although the problem has drawn tremendous attention from the government and media, limited academic research has been devoted to this problem, and few solutions have been proposed based on rigorous research. This study addresses the drug shortage problem from a supply chain perspective, a key aspect missing in the literature, and proposes to mitigate shortages through drug purchase ...

摘要：Subsidy programs are widely offered in both developing and developed countries to encourage consumption of products that generate positive social, health, and environmental externalities. We study the effect of subsidies on product consumption under uncertain market demand. To reach a target consumer population, the program sponsor may subsidize a for-profit or a not-for-profit firm on each unit of the product purchased by the firm or on each unit of the sale generated by the firm. We show tha...

摘要：We model a supply chain consisting of a supplier and multiple retailers facing deterministic demand. We denote some retailers as strategic in the sense that given the supplier inventory information, they will implement the optimal stocking policy by incorporating such information. On the other hand, some retailers are denoted as naive in the sense that they ignore supply information and resort to a simplistic ordering policy. Naive retailers learn the optimal policy over time and adjust their ...
