摘要：Retail store employees are increasingly being asked to pick orders from inventory. These tasks are performed under intense conditions and are often made more difficult because of high product variety and high degrees of product similarity. We conduct a real-effort task in a virtual environment where subjects must sort cubes into bins. We study task complexity by varying the degree of similarity between the cubes and task intensity by varying the arrival rate of the cube. We focus on four perfo...

摘要：This study investigates the operations of a novel service model, mobile charging, in which an e-commerce platform operator dispatches trucks equipped with charging piles to provide charging services for customers' electric vehicles with low battery levels. We model the platform-customer interaction with a Stackelberg game and explicitly characterize customers' optimal charging decisions under the platform's various service plans. In a general scenario that involves charging requests within a t...

摘要：Firms commonly use audits to ensure their suppliers comply with social responsibility standards. Yet audits are imperfect: a type I error occurs when a compliant supplier is mistakenly flagged as non-compliant, and a type II error occurs when a non-compliant supplier is overlooked. We study an assembly network in which a firm sources inputs from two suppliers and designs an audit program under a limited budget. For each audited supplier, the firm determines the audit accuracy and the associate...

摘要：The growing prominence of live streaming has attracted the attention from both e-commerce practitioners and the research community. This paper investigates the impact of online retailers adopting live streaming technology in business operations on their product sales, dissecting dual roles of live streaming: information provision and customer relationship management. Leveraging multiple archival data sources, we combine econometrics with deep learning to analyze the nuanced, dual roles of live...

摘要：This article aims to study the impacts of disruption risk at different supplier tiers on the performance of both centralized anddecentralized supply chains. We consider a three-tier supply chain, containing a tier-0 firm (original equipment manufacturer[OEM]), two potential tier-1 suppliers, and two potential tier-2 suppliers. Either a tier-1 or a tier-2 supplier is susceptibleto disruption risk. We solve and analyze the optimal/equilibrium sourcing strategy and production quantities and compa...

摘要：Online asset-selling businesses, such as used cars and real estate platforms, have experienced remarkable growth in recent years. Unlike general retail operations, which make decisions at the stock-keeping unit level, asset selling operates at the individual unit asset level. Practical operational constraints (e.g., infrequent price adjustments within a limited timeframe) set asset-selling platforms apart from general retail. Further complicating decision-making are real-world uncertainties, s...

摘要：The direct impacts of long wait times in elections, such as lost wages for voters and suppressed turnout, are well-documented. Drawing upon the service operations literature, we hypothesize that such operational inefficiencies may have far-reaching consequences beyond the immediate voter experience, in particular, the spread of political misinformation. Using a novel dataset that combines granular measures of voter wait times from cellphone location data, social media content, and demographic ...

摘要：Temporary economic shocks in local employment ecosystems, events that create temporary alternate employment opportunities for workers, tend to create operational challenges for firms. We investigate two dimensions of these challenges faced by firms that engage workers performing low-skilled tasks in the agricultural industry. We seek to understand (i) which workers leave during these shocks, and (ii) whether workers who choose to stay exhibit any change in their productivity. Both of these ans...

摘要：Motivated by algorithmic targeting and data management, we explore a scenario where the seller holds an advantage over consumers regarding match-related information about products. The seller optimizes a product line consisting of two vertically differentiated products alongside an opaque product resulting from their mixture, strategically recommending these products to potential consumers. We model algorithmic targeting using an information design framework, and our investigation revolves aro...

摘要：In the post-pandemic era, multi-sourcing is rapidly becoming the preferred approach for companies to drive optimized cost, quality and turnaround times. However, multi-sourcing systems present a myriad of challenges in designing an effective planning model. In this article, we propose a robust capacity planning model with multiple supply sources, and demonstrate how the capacity plan can be efficiently solved via a parsimonious mean-variance approach. We apply the max-min criterion to design a...
