Title: Simulating Counterfeit Personal Protective Equipment (PPE) Supply Chains During Covid-19
Increased demand for medical supplies, and specifically respirators and face masks, during the Covid-19 pandemic along with the inability of legitimate suppliers to meet these needs created a window of opportunity for counterfeiters to capitalize on the supply chain disruptions caused by a global health crisis. Both legitimate and illicit businesses began shifting their scope from sectors such as textiles to producing and distributing personal protective equipment (PPE), many of which were counterfeit or unauthentic products and thus unable to properly protect users. To study cost-effective disruption strategies, this study proposes a simulation-optimization framework. The framework is used to model counterfeiters’ behavior and analyze the effectiveness of different disruption strategies for counterfeit PPE supply chains during the Covid-19 pandemic.  more » « less

  1. The rapid growth of illicit supply chains during and after the Covid-19 pandemic reveals a need for effectively combating and preventing the cross-border movement of contraband, including but not limited to counterfeit goods. A proactive approach by companies along with public stakeholders, such as government agencies and individual consumers, toward disrupting illicit supply chains operating across borders is especially important during moments of global crisis when consumers are more susceptible to unknowingly purchasing substandard counterfeit products such as respirators. While marketplaces, platforms, and other legitimate businesses have worked to prevent movement of counterfeits and illicit goods through their services, the high adaptability and sophistication of counterfeiters requires more preventative and multistakeholder approaches. This article outlines a multidisciplinary and multilayered approach to detecting and disrupting illicit supply chains of counterfeit personal protective equipment (PPE) with a focus on respirators. It utilizes research conducted for a National Science Foundation (NSF) grant on Covid-19 related crime, including the advertising and sale of counterfeit respirators. One layer examines online content as seen by the end user and the activity of vendors or sellers used to advertise and sell counterfeit products. The research is also informed by data on the information, financial, and physical flows of counterfeit respirators obtained through a public-private partnership with George Mason University’s Terrorism, Transnational Crime and Corruption Center (TraCCC-GMU) and 3M, one of the largest manufacturers of respirators in the world. The article examines an important and relatively recent trend - how emerging technological shifts in the marketplace are affecting global security. Research from the TraCCC-GMU and 3M partnership, including a data sharing agreement, revealed that counterfeiters constantly change their modus operandi to continue selling illicit goods with impunity, facilitating illicit activity with the use and abuse of legitimate companies such as ecommerce marketplaces and social media. The article presents an overview of the current state of counterfeit supply chains and provides concrete policy recommendations on how legitimate companies can move beyond just removing listings but must also actively prevent these transnational crimes through innovative multidisciplinary approaches, advanced data analytics, and public awareness campaigns. The research also seeks to connect the dots to broader policy implications in terms of the legitimate economy and environmental sustainability.

  2. The underserved population could be at risk during the times of crisis, unless there is strong involvement from government agencies such as local and state Health departments and federal Center for Disease Control (CDC). The COVID-19 pandemic was a crisis of different proportion, creating a different type of burden on government agencies. Vulnerable communities including the elderly populations and communities of color have been especially hard hit by this pandemic. This forced these agencies to change their strategies and supply chains to support all populations receiving therapeutics. The National Science Foundation [National Science Foundation (NSF) Award Abstract # 2028612] funded RAID Labs to help federal agencies with strategies. This paper is based on a NSF funded grant to work on investigating supply chain strategies that would minimize the impact on underserved populations during pandemic. This NSF funded study identified the phenomena of last mile importance. The last mile transportation concept was critical in saving lives during the pandemic for underserved populations. The supply chain model then maximizes social goods by sending drugs or vaccines to the communities that need it the most regardless of ability to pay. The outcome of this study helped us prioritize the communities that need the vaccines the most. This informs our supply chain model to shift resources to these areas showing the value in real time prioritization of the COVID-19 supply chain. This paper provides information can be used in our healthcare supply chain model to ensure timely delivery of vaccines and supplies to COVID-19 patients that are the most vulnerable and hence the overall impact of COVID-19 can be minimized. The use of electrical vehicles for last mile transportation can help in significantly fighting the climate change.

  3. The initial months of the COVID-19 pandemic were marked by widespread shortages of personal protective equipment (PPE) because of surging demand and a fragile global supply chain. In response, many domestic suppliers pivoted to producing PPE, such as masks and face shields, made possible by low material costs and simple designs. A key challenge that remained was the lack of an established marketplace for nontraditional suppliers of PPE to connect with healthcare facilities in need. To address this inefficiency, we launched an online platform, Shield-Net, to match requests for face shields with new suppliers of PPE. Our platform was based on an optimization model that produced supplier-requester pairs and took into account request urgency, request size, production capacity, location, and product type. During the period of March to September 2020, Shield-Net produced 390 matches, resulting in the shipment of more than 50,000 face shields to 68 unique requesting organizations. Supplier-requester proximity was found to be the only statistically significant variable in the success of a match. In this paper, we discuss the development and impact of our matching platform, as well as lessons learned during its operation. History: This paper was refereed.

    Abstract The COVID-19 pandemic has reshaped the demand for goods and services worldwide. The combination of a public health emergency, economic distress, and misinformation-driven panic have pushed customers and vendors towards the shadow economy. In particular, dark web marketplaces (DWMs), commercial websites accessible via free software, have gained significant popularity. Here, we analyse 851,199 listings extracted from 30 DWMs between January 1, 2020 and November 16, 2020. We identify 788 listings directly related to COVID-19 products and monitor the temporal evolution of product categories including Personal Protective Equipment (PPE), medicines (e.g., hydroxyclorochine), and medical frauds . Finally, we compare trends in their temporal evolution with variations in public attention, as measured by Twitter posts and Wikipedia page visits. We reveal how the online shadow economy has evolved during the COVID-19 pandemic and highlight the importance of a continuous monitoring of DWMs, especially now that real vaccines are available and in short supply. We anticipate our analysis will be of interest both to researchers and public agencies focused on the protection of public health.

  5. Abstract—Periods of unique economic distress such as the COVID-19 pandemic can be quite difficult for small businesses. Challenges acquiring the supplies necessary to adhere to safety regulations created in the wake of such events can introduce stress on these businesses. This is further exacerbated when supply chains have slowed down, leading to global shortages from most large suppliers. This paper proposes a platform to aid such businesses in procuring COVID-19 related supplies such as Personal Protective Equipment (PPE) from one another, leveraging advanced data acquisition, integration, and Natural Language Processing (NLP) methods. With the pandemic end in sight, the platform described in this paper can be reused for other emergencies such as hurricanes, floods, among others. The proposed platform supports business transactions within a Buyer’s Club (BC), keyword-based sourcing of new businesses to join the platform, and matching products to relevant regulations using greater-than-word length encoding, helping businesses comply with the ever-changing regulatory landscape.
