摘要：Aid organizations choose their service providers through reverse auctions to decrease their operational costs, and many of them award the contracts to the lowest bidders, which often leads to aggressive bidding practices and compromised service quality. This is known as the abnormally low bids (ALBs) problem in public procurement. An ALB is defined as an unrealistically low bid submitted to win an auction, an amount at which the auctioned service cannot be provided reliably. The current litera...

摘要：The growing population in cities and booming e-commerce activities create huge demand for urban last-mile delivery, exerting intense pressure on the cities' well-being. To keep congestion and pollution under control, a consolidator can operate an urban consolidation center (UCC) to bundle shipments from multiple carriers before the last-mile delivery. Alternatively, the consolidator can operate a peer-to-peer platform for the carriers to share delivery capacity. We provide guidance for the con...

摘要：The price-setting newsvendor problem is well studied in the literature. However, it is commonly assumed that retailers have complete demand information modeled as a function of price and random noise. In reality, a retailer may have very limited information on a demand model because a retailer who has exercised only a few prices does not have sufficient information to accurately estimate a demand model. This creates a gap between academic research and practical applications. In this study, we ...

摘要：Over the past two decades, there has been explosive growth in the application of robust optimization in operations management (robust OM), fueled by both significant advances in optimization theory and a volatile business environment that has led to rising concerns about model uncertainty. We review some common modeling frameworks in robust OM, including the representation of uncertainty and the decision-making criteria, and sources of model uncertainty that have arisen in the literature, such...

摘要：We study the choice-based constrained assortment optimization problem under the multilevel nested logit model with a no-purchase option in every choice stage. For this problem, each candidate product is associated with a fixed profit. The goal is to identify the optimal assortment satisfying a cardinality constraint to maximize the expected profit per customer. There is a cardinality limitation imposed on nodes in the second lowest level. A polynomial-time algorithm with computational complexi...

摘要：We investigate the optimal Bayesian dynamic pricing and demand learning policy over short selling horizons, where the pricing decisions are time-sensitive. The seller fine-tunes the price near an incumbent price in order to maximize the total revenue. The existing literature focuses on policies that are asymptotically optimal, that is, near optimal when the selling horizons are sufficiently long, but little is known about the optimal Bayesian policies, especially over short horizons. We formul...

摘要：We investigate the benefits of on-site printing at remote geographic locations, where access to spare parts is intermittent and supplies are replenished at fixed intervals. Organizations typically have no solution to spare parts shortages other than expensive expediting orders, or waiting for a part to arrive with the next replenishment. We investigate whether on-site three-dimensional (3D) printing of spare parts can bring relief. Our work extends dual-sourcing literature with fixed order cyc...

摘要：What are the attributes of the best-performing supply chains? According to Lee (2004), the best supply chains are agile, adaptable, and ensure the interests of all participating companies stay aligned, that is, The Triple-A framework. Fifteen years later, we find global supply chains exposed, with an increasing frequency and alarming severity, to low probability disruptive shocks. We revisit the question of the current attributes of best-performing supply chains in a highly uncertain and risk ...

摘要：In his 2004 article, Professor Hau Lee argues that the best supply chains are not only fast and cost-effective but also agile, adaptable, and aligned. The concept of triple-A supply chains has been extensively studied in academic and trade publications and integrated into numerous operations and supply chain management curricula. It has also influenced the management approach of leaders around the world. Yet since the triple-A concept was first developed, supply chains have become increasingly...

摘要：Dual channel distribution benefits upstream manufacturers but may irritate downstream retailers. The channel conflict only seems to aggravate when retailers are put at information disadvantage. We show this need not be the case. (i) We demonstrate upstream private information can improve channel efficiency and consumer surplus. The main mechanism is the offsetting interplay of signaling distortion and double marginalization: with private selling cost, the manufacturer may signal her cost by cu...
