Disruption Risk Mitigation In Supply Chains: The Risk Exposure Index Revisited, Sarah Yini Gao, David Simchi-Levi, Chung-Piaw Teo, Zhenzhen Yan
Disruption Risk Mitigation In Supply Chains: The Risk Exposure Index Revisited, Sarah Yini Gao, David Simchi-Levi, Chung-Piaw Teo, Zhenzhen Yan
Research Collection Lee Kong Chian School Of Business
Simchi-Levi et al. (2014, 2015a) proposed a novel approach using the Time-To-Recover (TTR) parameters to analyze the Risk Exposure Index (REI) of supply chains under disruption. This approach is able to capture the cascading effects of disruptions in the supply chains, albeit in simplified environments -- TTRs are deterministic, and at most one node in the supply chain can be disrupted. In this paper, we proposed a new method to integrate probabilistic assessment of disruption risks into the REI approach and measure supply chain resiliency by analyzing the Worst-case CVaR (WCVaR) of total lost sales under disruptions.We show that the …
Combating Child Labor: Incentives And Information Disclosure In Global Supply Chains, Soo-Haeng Cho, Xin Fang, Sridhar Tayur, Ying Xu
Combating Child Labor: Incentives And Information Disclosure In Global Supply Chains, Soo-Haeng Cho, Xin Fang, Sridhar Tayur, Ying Xu
Research Collection Lee Kong Chian School Of Business
Problem definition: We investigate multinational firms’ inspection and pricing strategies to address the challenges of combating child labor in global supply chains. We also examine how several factors (such as information disclosure, goodwill loss, inspection cost, external monitoring by nongovernmental organizations (NGOs), and penalty scheme) affect firms’ incentives to use different strategies to combat child labor. Academic/practical relevance: Nearly 200 million children are engaged in child labor, many in developing countries that are part of the supply base of global manufacturing networks. However, there has been little research on evaluating the impact of firms’ strategies and NGOs’ initiatives …
Exploring The Effect Of Waivers To The Non-Manufacturer Rule On Contract Awards To Small Businesses, William A. Muir, Michael J. Gravier, Timothy G. Hawkins
Exploring The Effect Of Waivers To The Non-Manufacturer Rule On Contract Awards To Small Businesses, William A. Muir, Michael J. Gravier, Timothy G. Hawkins
Marketing Department Faculty Conference Proceedings
The U.S. government regularly participates as a buyer in industrial markets where products are customarily sold through indirect marketing and distribution chains, separating buyers from manufacturers. In many cases, these marketing, distribution, and store-front activities add significant value for buyers, such as through pre- and post-sale service and support, improvements to product availability, and reductions in per-unit pricing (e.g., via economies due to warehousing, transportation, and ordering processes). Accordingly, the government (U.S. Small Business Administration) has, in some instances, issued class waivers to the requirements of the “non-manufacturer rule” (15 U.S.C. § 657s) when no small business manufacturers exist for …
Adaptive Workflow Design Based On Blockchain, Daniel Narh Treku, Jun Sun
Adaptive Workflow Design Based On Blockchain, Daniel Narh Treku, Jun Sun
Information Systems Faculty Publications
Increasingly, organizational processes have become more complex. There is a need for the design of workflows to focus on how organizations adapt to emergent processes while balancing the need for decentralization and centralization goal. The advancement in new technologies especially blockchain provides organizations with the opportunity to achieve the goal. Using blockchain technology (i.e. smart contract and blocks of specified consensus for deferred action), we leverage the theory of deferred action and a coordination framework to conceptually design a workflow management system that addresses organizational emergence (e-WfMS). Our artifact helps managers to predict and store the impact of deferred actions. …
Certification Value To Consumers In The Coffee Industry, Alexandra Aubron
Certification Value To Consumers In The Coffee Industry, Alexandra Aubron
Honors Projects in Global Supply Chain Management
The coffee industry is a growing industry characterized by a complex system of interrelated economic, environmental and social issues. While having appeared initially as a response to environmental and social movements, certifications are now used by coffee retailers as a business tool to satisfy consumer demand for greater transparency. They are used as indicators that the coffee retailer is investing in traceability of its supply chain. The purpose of this study is to assess the effectiveness of coffee certifications in practice by answering the following research question: are certifications successful in communicating the various traceability efforts made by retailers? To …

Spun Truths: Outcomes Of Mongolia’S Cashmere Program In Domestic Processing Facilities And Supply Chain, Daniel Strodel
Spun Truths: Outcomes Of Mongolia’S Cashmere Program In Domestic Processing Facilities And Supply Chain, Daniel Strodel
Independent Study Project (ISP) Collection
Since Mongolia’s transition to a market economy cashmere goats' population quintupled and their share of the nation’s total live-stock doubled. Cashmere is Mongolia’s third largest export and herders’ primary source of cash income. However, Mongolian cashmere processing facilities operate well below capacity because they cannot compete with high prices paid by Chinese traders. The latest intervention in a series of industry reforms is the four year Cashmere Program, which is being implemented by the Mongolian Ministry of Agriculture and Light Industry. In order to increase the amount of cashmere processed and exported from Mongolia, the program invests in domestic processing …
Managing Wind-Based Electricity Generation In The Presence Of Storage And Transmission Capacity, Yangfang (Helen) Zhou, Alan Scheller-Wolf, Nicola Secomandi, Stephen Smith
Managing Wind-Based Electricity Generation In The Presence Of Storage And Transmission Capacity, Yangfang (Helen) Zhou, Alan Scheller-Wolf, Nicola Secomandi, Stephen Smith
Research Collection Lee Kong Chian School Of Business
We investigate the management of a merchant wind energy farm co‐located with a grid‐level storage facility and connected to a market through a transmission line. We formulate this problem as a Markov decision process (MDP) with stochastic wind speed and electricity prices. Consistent with most deregulated electricity markets, our model allows these prices to be negative. As this feature makes it difficult to characterize any optimal policy of our MDP, we show the optimality of a stage‐ and partial‐state‐dependent‐threshold policy when prices can only be positive. We extend this structure when prices can also be negative to develop heuristic one …

Knowledge Gap: Supply Chain Students And Employers, Kathryn Bules
Knowledge Gap: Supply Chain Students And Employers, Kathryn Bules
Honors Theses
This thesis project aims to identify the gap(s) between supply chain students and employers for both the preparedness and relative importance of the critical job skills employers seek in graduating students. This research is relevant because students view college as an investment that will pay off through better job placement and higher pay upon graduation. The problem is that some employers feel students do not have the skills necessary to be successful on the job. While there has been extensive research regarding a skills gap in graduating students and common criteria employer’s use to rank these students, there is minimal …
Humanitarian Logistics: Shipping Designs For The Post Disaster Cargo Surge, Nicholas L. Green
Humanitarian Logistics: Shipping Designs For The Post Disaster Cargo Surge, Nicholas L. Green
Theses and Dissertations
In 2017 Hurricane Maria devastated Puerto Rico. The humanitarian aid community scrambled a response to support the 3.4 million people affected by the disaster. In response, thousands of shipping containers filled with supplies were sent to the island. Numerous reports surfaced regarding significant delays in receiving the shipments. This research reviews the historical account of cargo throughput into Puerto Rico following Maria. A computer simulation built in ARENA compares various what-if scenarios based on empirically collected data and interviews with FEMA, port authorities, and commercial cargo carriers to determine how the humanitarian supply chain could improve for future disaster planning. …
Applying The Multiple Multidimensional Knapsack Assignment Problem To A Cargo Allocation And Transportation Problem With Stochastic Demand, Jocelin S. Maus
Applying The Multiple Multidimensional Knapsack Assignment Problem To A Cargo Allocation And Transportation Problem With Stochastic Demand, Jocelin S. Maus
Theses and Dissertations
The US military relies on airlift to not only deploy and sustain U.S. armed forces anywhere in the world but also to rapidly mobilize humanitarian efforts and supplies. Operations already impacted by the limited capacity of aircraft also fall prey to dynamic requirements and differing priorities of multiple global locations. A growing concern for the modern military budget is how to provide airlift functions expediently and economically while mitigating the costs of shortfalls and overages. Utilizing fiscal year 2017-2018 cargo data published by the 618th Air Operations Center and modeling this problem as a multiple multidimensional knapsack assignment problem (MMKAP), …
Predicting Failures Of The Brazilian Air Force Tucano Fleet Using Survival Analysis, Luciana Mesquita Monteiro
Predicting Failures Of The Brazilian Air Force Tucano Fleet Using Survival Analysis, Luciana Mesquita Monteiro
Theses and Dissertations
During the life of an aircraft, several failures may occur causing unplanned maintenance and costs of parts, labor, transportation, lost opportunities, and operations, among others. The prediction of these events becomes especially difficult for new airframes, since they do not have many flight hours or enough data to observe failures. This study analyzes and model the time between failures (TBF) of the Brazilian Air Force T-27 Tucano fleet by applying various non-parametric, semi-parametric, and parametric statistical models, to the TBF, such as the descriptive statistics, Kaplan-Meier estimators, Cox proportional hazards models, with or without frailty, and survival regression models, with …
Fuzzy Inference Systems For Risk Appraisal In Military Operational Planning, Curtis B. Nelson
Fuzzy Inference Systems For Risk Appraisal In Military Operational Planning, Curtis B. Nelson
Theses and Dissertations
Advances in computing and mathematical techniques have given rise to increasingly complex models employed in the management of risk across numerous disciplines. While current military doctrine embraces sound practices for identifying, communicating, and mitigating risk, the complex nature of modern operational environments prevents the enumeration of risk factors and consequences necessary to leverage anything beyond rudimentary risk models. Efforts to model military operational risk in quantitative terms are stymied by the interaction of incomplete, inadequate, and unreliable knowledge. Specifically, it is evident that joint and inter-Service literature on risk are inconsistent, ill-defined, and prescribe imprecise approaches to codifying risk. Notably, …
Examining The Express Supportability Module: Implementing An Autoregressive Distributed Lag Approach With Air Force Maintenance Data, Troy J. St Peter
Examining The Express Supportability Module: Implementing An Autoregressive Distributed Lag Approach With Air Force Maintenance Data, Troy J. St Peter
Theses and Dissertations
Launched in 1996, EXPRESS (Execution and Prioritization of Repairs Support System) is a program integral to the Air Force reparable supply chain. Daily, EXPRESS relies on a number of data sources and individual modules like the Supportability Module to determine which necessary repairs can and should be made. The Supportability Module examines the prioritized list of repairs and checks four constraints in order to decide whether each repair can be made given current resources. According to the logic of the module, a single constraint failure means that subsequent resource checks are not made before evaluating the next repair. Unfortunately, this …
