Blockchain For A Resilient, Efficient, And Effective Supply Chain, Evidence From Cases, Adrian Gheorghe, Farinaz Sabz Ali Pour, Unal Tatar, Omer Faruk Keskin Jan 2021

Blockchain For A Resilient, Efficient, And Effective Supply Chain, Evidence From Cases, Adrian Gheorghe, Farinaz Sabz Ali Pour, Unal Tatar, Omer Faruk Keskin

In the modern acquisition, it is unrealistic to consider single entities as producing and delivering a product independently. Acquisitions usually take place through supply networks. Resiliency, efficiency, and effectiveness of supply networks directly contribute to the acquisition system's resiliency, efficiency, and effectiveness. All the involved firms form a part of a supply network essential to producing the product or service. The decision-makers have to look for new methodologies for supply chain management. Blockchain technology introduces new methods of decentralization and delegation of services, which can transform supply chains and result in a more resilient, efficient, and effective supply chain. This …

Inducing Compliance With Postmarket Studies For Drugs Under Fda's Accelerated Approval Pathway, Liang Xu, Hui Zhao, Nicholas C. Petruzzi Jan 2021

Inducing Compliance With Postmarket Studies For Drugs Under Fda's Accelerated Approval Pathway, Liang Xu, Hui Zhao, Nicholas C. Petruzzi

Research Collection Lee Kong Chian School Of Business

Problem definition: In 1992, the Food and Drug Administration (FDA) instituted the accelerated approval pathway (AP) to allow promising drugs to enter the market based on limited evidence of efficacy, thereby permitting manufacturers to verify true clinical benefits through postmarket studies. However, most postmarket studies have not been completed as promised. We address this noncompliance problem. Academic/practical relevance: The prevalence of this noncompliance problem poses considerable public health risk, thus compromising the original purpose of a well-intentioned AP initiative. We provide an internally consistent and implementable solution to the problem through a comprehensive analysis of the myriad complicating factors and …

Quantifying The Effects Of Aircraft Engine Upgrades On Operating And Support Costs, Bradford A. Myers, Edward D. White, Jonathan D. Ritschel, R. David Fass Jan 2021

Quantifying The Effects Of Aircraft Engine Upgrades On Operating And Support Costs, Bradford A. Myers, Edward D. White, Jonathan D. Ritschel, R. David Fass

Faculty Publications

For fixed wing aircraft within the U.S. Air Force, Operating and Support (O&S) costs encompass a large portion of total life cycle costs. O&S costs include fuel, maintenance, and engine upgrades. To the authors’ knowledge, no study to date has attempted to empirically quantify the realized effects of new aircraft engines on sustainment costs. Utilizing the Air Force Total Ownership Cost database, they focused on new engines appearing on the C-5s, C-130s, and C-135s. Although narrow in scope, results suggest newer engines have lower fuel costs. Maintenance costs for newer engines were not consistently higher or lower than the engines …

Peer-To-Peer Trade And The Economy Of Distributed Pv In China, Peiyun Song, Yiou Zhou, Jiahai Yuan Jan 2021

Peer-To-Peer Trade And The Economy Of Distributed Pv In China, Peiyun Song, Yiou Zhou, Jiahai Yuan

Research Collection School Of Computing and Information Systems

With the deepening of power market reform, distributed power generation is gaining momentum. This paper tests the distributed photovoltaic (DPV) economy under different business models by taking three provinces to stand for typical resource zones. The Internal return rate (IRR) is used to measure the economy, while the improved levelized cost of electricity (LCOE) is used to model the generation cost. Three business modes, namely pure producer (all generation sold to the grid), prosumer (self-use and the rest sold to the grid), and peer-to-peer trade (P2P, all generation traded via the grid) are studied. Results show that peer-to-peer trade is …

Adapting To Slow-Moving Crises: The Personal Protection Equipment Supply Chain In The Time Of Covid19, Jennifer Shullih, Stephen Lemay Jan 2021

Adapting To Slow-Moving Crises: The Personal Protection Equipment Supply Chain In The Time Of Covid19, Jennifer Shullih, Stephen Lemay

Association of Marketing Theory and Practice Proceedings 2021

In this paper, we look at the supply chain for PPE during the COVID-19 pandemic of 2020. We look at the way the supply chain has responded to the pandemic, the coordination of the supply chain relative to the needs of primary users, and the consequences of its use. We find that the supply chain has continued to function more as a commercial supply chain than as an emergency supply chain largely because of a lack of centralized coordination. We include an analysis of existing concepts as they apply to this supply chain, but also incorporate preliminary results from a …

A Case Study In Supply Chain Ethics: Medical Supplies Are Us, Michael J. Dwyer Jan 2021

A Case Study In Supply Chain Ethics: Medical Supplies Are Us, Michael J. Dwyer

Association of Marketing Theory and Practice Proceedings 2021

A hypothetical scenario is presented for consideration as a case study on both delivery logistics cost controls and ethical issues. Set in a regional medical supply company in the fictitious country, Costaguana, the actor needs to first unpack a supply chain issue as related to setting up a system to create cost savings to fund a non-government/non-profit organization. The delivery logistics with an established supplier for the company is explained in detail along with intra- and inter-company logistics’ relationships. Then an ethical issue is presented as related to the newfound savings from shipping for the organization. The case is presented …
