Optimal Policies And Heuristics To Match Supply With Demand For Online Retailing, Qiyuan Deng, Xiaobo Li, Yun Fong Lim, Fang Liu

Research Collection Lee Kong Chian School Of Business

Problem definition: We consider an online retailer selling multiple products to different zones over a finite horizon with multiple periods. At the start of the horizon, the retailer orders the products from a single supplier and stores them at multiple warehouses. The retailer determines the products’ order quantities and their storage quantities at each warehouse subject to its capacity constraint. At the end of each period, after random demands in the period are realized, the retailer chooses the retrieval quantities from each warehouse to fulfill the demands of each zone. The objective is to maximize the retailer’s expected profit over …

An Exponential Cone Programming Approach For Managing Electric Vehicle Charging, Li Chen, Long He, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

To support the rapid growth in global electric vehicle adoption, public charging of electric vehicles is crucial. We study the problem of an electric vehicle charging service provider, which faces (1) stochastic arrival of customers with distinctive arrival and departure times, and energy requirements as well as (2) a total electricity cost including demand charges, costs related to the highest per-period electricity used in a finite horizon. We formulate its problem of scheduling vehicle charging to minimize the expected total cost as a stochastic program (SP). As this SP is large-scale, we solve it using exponential cone program (ECP) approximations. …

The Downstream Impact Of Upstream Tariffs: Evidence From Investment Decisions In Supply Chains, Thorsten Martin, Clemens A. Otto

Research Collection Lee Kong Chian School Of Business

We study how US manufacturing firms' investment responds to tariff reductions in supplier industries. Our estimates, based on tariff reductions following multinational trade agreements, suggest that a hypothetical 10% reduction of all upstream tariffs would increase downstream investment by 4% to 6%. This estimate is not explained by decreasing uncertainty and stems from tariff reductions for homogeneous and low-R\&D inputs, consistent with the investment response resulting from cost reductions rather than superior foreign technology embodied in imported inputs. Evidence from an instrumental variable estimation using the sudden increase in Chinese import penetration suggests that import competition also increases downstream investment.

Appointment Scheduling With Delay Tolerance Heterogeneity, Shuming Wang, Jun Li, Marcus Ang, Tsan Sheng Ng

Research Collection Lee Kong Chian School Of Business

In this study, we investigate an appointment sequencing and scheduling problem with heterogeneous user delay tolerances under service-time uncertainty. We aim to capture the delay-tolerance effect with heterogeneity, in an operationally effective and computationally tractable fashion, for the appointment scheduling problem. To this end, we first propose a Tolerance-Aware Delay (TAD) index that incorporates explicitly the user-tolerance information in delay evaluation. We show that the TAD index enjoys decision-theoretical rationale in terms of Tolerance Sensitivity, Monotonicity, Convexity and Positive Homogeneity, which enables it to incorporate the frequency and intensity of delays over the tolerance in a coherent manner. Specifically, the …

Do Firms Follow Through On Environmental Commitments? An Empirical Examination, Rick Hardcopf, Kevin Linderman, Rachna Shah

Management Faculty Publications

In response to ever-increasing pressure from stakeholders to reduce the impact of their operations and supply chain on the natural environment, firms frequently make public commitments to improve environmental performance. However, the commitments are difficult to validate and thus of unknown quality. Understanding whether and when the commitments are valid proxies for action is essential because they are used by environmentally conscious stakeholders to assess firm environmental performance in anticipation of buying from, investing in, working for, or selling to a firm. Results from examining 442 U.S. manufacturing firms show that firms generally follow through on such commitments. Larger firms …

Faids: Artificial Intelligence Developmental Systems Framework For Predicting And Preventing Cyberattacks In Supply Chain Networks, Lordt Becklines

Research & Publications

Cyber threats and attacks disrupt and damages supply chain networks (SCNs), which are complex and interlinked. Current methods to predict and prevent cyberattacks are inadequate and ineffective. This research proposes an AI developmental systems framework (FAIDS) to protect SCNs from cyberattacks. The framework has four components: (1) an AI threat intelligence system; (2) an AI risk assessment system; (3) an AI decision support system; and (4) an AI learning and adaptation system. The framework is tested on a simulated retail SCN. The results show that the framework can predict and prevent cyberattacks and improve the network's resilience and security. The …

Coffee In Brasil: Sustainability And The Role Of Intermediaries, Livia Petzinger

Capstone Collection

ABSTRACT

Coffee is traded in a highly complex global value chain where countless sustainability initiatives have emerged to address social, economic, and environmental issues, challenges which persist due to dominance of the market structure by largescale traders and roasters. Specialty coffee and direct trade have emerged as alternative trade arrangements that promote high-quality coffee through the use of sustainable practices, transparency, and a shortened supply chain. This research analyzes the role that intermediaries in the Brazilian specialty coffee supply chain play in the implementation of sustainability initiatives asking what kinds of sustainability practices they implement and why, and how this …

Locking In Overseas Buyers Amid Geopolitical Conflicts, Di Fan, Pengcheng Ma, Lin Cui, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

Geopolitical conflicts, particularly economic ones, introduce significant uncertainties into the global supply chain. The impact of these conflicts on cross-border buyer-supplier transactions remains underexplored, as does the capability of global suppliers to mitigate such risks by locking in their foreign buyers. Employing a combined perspective of resource dependence theory and transaction cost economics, we examine a natural experiment to investigate the effects of the 2018 U.S.-China trade war on the transactional relationships between Chinese suppliers and their U.S. buyers. Our study reveals that the trade war generally adversely affected these buyer-supplier transactional relationships, leading to a negative abnormal transaction value …
