Studying the Supply Chain 

Tuesday, November 17, 2020

The year 2020 has the highest search volume for “supply chain” during the last 10 years, according to Google Trends data. That’s one indication of Americans COVID-19-fueled interest in the process for getting consumer goods; the other is rather obvious: empty shelves of toilet paper, diapers, and even Dr. Pepper. 

For faculty members in the Carlson School Supply Chain and Operations Department, those concerns and many others, including how to respond to the health care crisis of COVID-19, meant it was time to get to work on multiple fronts. 

 

Research

 

Impact of Telemedicine on Rural Minnesota

COVID-19 has led to a focus on the use of telemedicine to overcome geographical barriers and increasing access to care, reducing costs, and improving quality. So, who benefits the most?

Those in rural locations and areas where poverty is low, according to the results from a new study by former Carlson School PhD student Xiaojin Liu (now an assistant professor at Virginia Commonwealth University), Associate Professor Susan Meyer Goldstein, and Professor, Department Chair and Elmer L. Andersen Chair in Sustainable Supply Chain Kingshuk Sinha.

“Taken together, these findings show urban poor patients with large health disparities aren’t using telemedicine,” said Meyer Goldstein. “Knowing this will help to design and manage supply chains to improve healthcare access for that population and others.” 

Additionally, the authors found cost and low local demand are why providers haven’t started or expanded telemedicine options. One reason to invest, according to the research: improved community health. Increased use of telemedicine over time in Minnesota clinics is associated with positive gains in health indicators. 

 

Nationalism’s Effect on a Potential Vaccine
With a limited supply of critical products such as personal protective equipment (PPE) and life-saving drugs, several national governments  implemented policies to limit exporting such products and serve their citizens first. Now, there is growing concern that similar measures will occur for a COVID-19 vaccine, a phenomenon dubbed "vaccine nationalism.”

Professor and Curtis L. Carlson Chair in Supply Chain Karen Donohue, Assistant Professor Karthik Natarajan, and PhD student Vincent Yu have found these policies do not always work as intended.

“In some situations, the policies have been a factor for vaccine manufacturers to move production to another country,” said Donohue. “And we found that local, and sometimes even total, capacities may decrease if the investment cost is high.” 

With these initial findings, the research team is currently investigating how changes in capacity investments may influence public health outcomes, by taking into account the role of herd immunity, and what behavioral factors may further influence decision-makers' choices.

 

Understanding Why Some Restaurants Struggled
It’s no secret that small restaurants are struggling. Is there a path forward? Assistant Professor Hailong Cui and colleagues at the University of Southern California think so and are working now to determine the right responses.

Using unique data from a food distributor in California, the researchers are gathering additional data to carry out econometric analyses to assist restaurants in different stages of operation maintain sufficient sales to survive. Also, they plan to look at barriers facing minority-owned, small restaurants who have been disproportionately impacted.

 

Teaching and Outreach

Conducting research is just one aspect of the department's work. In the classroom, instructors and students responded to the crisis in real-time. For example, Sinha mapped the COVID-19 care supply chain, end-to-end, in his spring semester graduate elective on supply chain management in the medical device and health sector. And Professional Director of the MS in Supply Chain Management program Scott Martens advised student capstone projects that assisted one client in developing direct-to-consumer capabilities for products and helped another client analyze the impact of supply chain policy changes. 

As part of the Carlson Consulting Enterprise, Managing Director Siddharth Chandramouli, Associate Director Dave MacCallum, and Meyer Goldstein, who serves as academic director, are also supporting supply chain-related projects. This includes: determining uses for excess catch from fisheries in northern Minnesota who are facing declines in demand from restaurants; helping a large healthcare company determine the enduring way that the COVID-19 pandemic will change public health services in the U.S., and supporting a reimagination of employment training to meet the needs of job-seekers in a post-pandemic world. 

Sinha also moderated a roundtable discussion convened by U.S. Rep. Angie Craig (D-MN), co-founder of the bipartisan Congressional Supply Chain Caucus, involving leaders from the food and agriculture, medical devices, transportation and logistics, small business, and global manufacturing sectors in June 2020.

 

 

供应链研究

2020年11月17日,星期二


       Google Trends数据显示,2020年“供应链”一词的搜索量是过去10年中的最高值。这一方面说明美国人在新冠疫情期间为了获取消费品而对供应链产生了兴趣,另一个原因则十分明显:卫生纸、尿布、甚至胡椒博士饮料都断货了。

       上述问题以及如何应对新冠医疗危机等问题,意味着卡尔森学院供应链与运营系的研究工作需要多线并进。

 

研究

远程医疗对明尼苏达州农村地区的影响
        因为新冠疫情的关系,远程医疗被广泛应用以克服地域限制、增加医护覆盖面、降低医疗费用、提高医护质量。那么,哪个群体从中受益最多?

        是贫困率较低的农村地区。该结论来自于卡尔森学院前博士刘晓金(音译)(现任弗吉尼亚联邦大学副教授)、副教授Susan Meyer Goldstein、以及担任系主任和Elmer L. Andersen Chair in Sustainable Supply Chain的Kingshuk Sinha教授的最新研究成果。

        Meyer Goldstein表示:“我们的研究结果显示,医疗条件悬殊较大的农村地区的贫穷病人总体上并不使用远程医疗。这个信息有助于供应链的设计和管理,从而提高各个群体的医疗保障程度。”

        此外作者们还发现,远程医疗无法展开或规模较小的原因是成本高、本地需求低。研究显示,投资远程医疗的一个主要原因是为了提高社区健康水平。明尼苏达州的医院加大了远程医疗服务的力度,长期来看此举将改善医疗指标。

 

民族主义对疫苗研发的影响

        由于个人防护用品、关键药物等产品的供应量有限,多个国家的政府颁布政策限制此类产品的出口,优先供应国内市场。目前,越来越多人担忧新冠疫苗也会收到此类限制,该现象被称为“疫苗民族主义”。

        担任Curtis L. Carlson Chair in Supply Chain的Karen Donohue教授、副教授Karthik Natarajan、博士生Vincent Yu发现,这类政策往往难以达成目的。

        Donohue表示:“在某些情况下,这些政策会迫使疫苗生产厂商把生产转移到其他国家。如果投资成本过高,本地产能甚至总产能会降低。”

        得到上述初步研究结果后,该研究小组目前已经调查产能投资变化对公共卫生状况的影响,并考虑群体免疫、影响决策者选择的行为因素等要素。

 

为什么一些餐馆会陷入困境?

        众所周知,小餐馆陷入了困境。它们还有前途吗?副教授崔海龙(音译)和南加利福尼亚大学的同事给出了肯定的答案,并且正在研究小餐馆的正确应对措施。

        研究者使用了加利福尼亚一家食品经销商的数据,开展计量经济学研究,帮助各类餐馆维持销售以求生存。此外,他们计划研究遭受重创的由少数族裔运营的小型餐馆。

 

教学与外联

        研究只是该系的部分工作。该系师生在课堂学习中研究危机、作出实时反应。例如,在春季学期的研究生选修课程医疗设备与卫生领域供应链管理中,Sinha教授列出了新冠肺炎医疗服务的端到端供应链。供应链管理项目的MS Professional Director Scott Martens在巅峰项目中要求学生帮助一位客户开发产品直达消费者的能力,帮助另一位客户分析供应链政策变化的影响。

        Carlson Consulting Enterprise总经理Siddharth Chandramouli、副总经理Dave MacCallum、学术主任Meyer Goldstein也参与了供应链项目。例如:研究在餐饮业需求下降后,明尼苏达州北部捕鱼业的多余鱼获的去处;帮助一家大型医疗企业研究新冠疫情对美国公共卫生服务的长期影响;帮助职业培训行业提升能力,满足疫情后求职者的需求。

        2020年6月,Sinha教授主持了由美国代表、两党Congressional Supply Chain Caucus的联合创始人Angie Craig (D-MN)发起的圆桌会议,与会者包括食品与农业、医疗设备、交通物流、小企业、全球制造业等行业的领导者。
