Analytics For Hospital Resource Planning: Two Case Studies, Jingui Xie, Weifen Zhuang, Marcus Ang, Mabel C. Chou, Li Luo, David D. Yao

Research Collection Lee Kong Chian School Of Business

Using real data and process flows from two large hospitals (in Singapore and in Chengdu, China) as cases, we illustrate how to apply certain modeling and optimization techniques, along with simulation as a validation tool, to hospital resource planning problems. We demonstrate how these simple analytical tools can help achieve significant improvements in both patient service and resource utilization, and without the need to increase the overall level of existing capacities. Two resource planning problems are studied in detail, one concerns the re-balancing of bed capacities among various wards, and the other addresses the allocation of medical diagnostic resource among …

Examining The Influence Of Source Dependence On Supplier Performance In The Usaf Organic Supply Chain, Thomas A. Counter

Theses and Dissertations

The purpose of this study is to examine the U.S. Air Force's dependence toward sole sourcing and how that influences procurement outcomes in terms of supplier performance. This research used linear regression to explain the effect of source dependence and supplier size on performance categories for 326 suppliers. The five supplier performance categories in the study included timeliness, cost control, quality, business relations, and regulatory compliance. The research found that the USAFs dependence on sole sourcing had a small but statistically significant influence on all five aspects of supplier performance, with timeliness being the most adversely impacted.

Developing A Basic Formal Supply Chain Ontology To Improve Communication And Interoperability, David Morrow

Theses and Dissertations

Information is crucial to supply chain performance because it is used to make decisions and trigger actions. Organizations across world-class supply chains increasingly use information technology to analyze and process supply chain data. However, supply chain management lacks a common language, making information exchange difficult. An ontology can provide a standardized framework that organizes a given knowledge domain. This research proposes a common language for developing a supply chain ontology that can be built into a basic formal ontology understood by both humans and computers. According to current research, an established and widely used supply chain framework is a good …

Modeling And Solving The Outsourcing Risk Management Problem In Multi-Echelon Supply Chains, Arian A. Nahangi

Master's Theses

Worldwide globalization has made supply chains more vulnerable to risk factors, increasing the associated costs of outsourcing goods. Outsourcing is highly beneficial for any company that values building upon its core competencies, but the emergence of the COVID-19 pandemic and other crises have exposed significant vulnerabilities within supply chains. These disruptions forced a shift in the production of goods from outsourcing to domestic methods.

This paper considers a multi-echelon supply chain model with global and domestic raw material suppliers, manufacturing plants, warehouses, and markets. All levels within the supply chain network are evaluated from a holistic perspective, calculating a total …

Inter-Organizational Systems Use And Supply Chain Performance: Mediating Role Of Supply Chain Management Capabilities, David Asamoah, B. Agyei-Owusu, Francis Andoh-Baidoo, Emmanuel Wusuhon Yanibo Ayaburi

Information Systems Faculty Publications

Inter-organizational Systems (IOS) are network-enabled information systems that extend boundaries of an organization. There is a growing interest among researchers and practitioners to understand how the use of IOS enhances firm performance. In this study, we examine how IOS use impacts an organization’s supply chain management (SCM) capabilities and supply chain performance. Drawing on the resource-based view theory, we examine two mechanisms that are essential for enhanced supply chain performance: (a) efficient IOS external utilization regarding its networked partners and (b) the maximization of IOS organizational management capabilities in supply chain management. Using data from 193 respondents from various manufacturers …

Multi-Period Lot-Sizing With Supplier Selection: Structural Results, Complexity And Algorithms, Meichun Lin, Woonghee Tim Huh, Guohua Wan

Research Collection Lee Kong Chian School Of Business

We consider a multi-period lot-sizing problem with multiple products and multiple suppliers. Demand is deterministic and time-varying. The objective is to determine order quantities to minimize the total cost over a finite planning horizon. This problem is strongly NP-hard. For a special case, we extend the classical zero-inventory-ordering principle and solve it by dynamic programming. Based on this new extension, we also develop a heuristic algorithm for the general problem and computationally show that it works well.

Integration Of Blockchain Technology Into Supply Network For Resilient And Efficient Acquisition [Video], Adrian Gheorghe, Farinaz Sabz Ali Pour, Unal Tatar, Omer Faruk Keskin, Cornel Vintila, Laura Manciu

Engineering Management & Systems Engineering Faculty Publications

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.

Food Hubs And Rebuilding Missing Middle Market Structure In Agriculture: The Social In Supply Chain Development, Stephen Luoni

Community Design Center Faculty Publications and Presentations

Tens of millions of Americans became food insecure during the COVID-19 pandemic as independent farmers dumped millions of tons of food due to economic lockdowns. Yet contract growers looped into vertically integrated monopoly supply chains escaped system breakdowns. Food provisioning is often seen as polarized between local scale and continental/ global market scale. Food supply and consumption are functions more of market structure than scale. Farmers reliant on direct sales to local restaurants, schools, universities, and hospitals saw their markets evaporate overnight. This Food Away from Home market constitutes 54 percent of food consumed nationally yet is vulnerable since direct-to-consumer …

Partner Trust Level In Collaborative Demand Forecast Sharing And Its Impact On Supply Chain Profitability, Seong-Hyun Nam

School of Entrepreneurship Faculty Publications

Considering trust as a critical factor for successful collaborative demand forecast sharing, this paper studies the dynamic relationship between trust level-based forecasting capability and supply chain profitability. We develop a forecasting coordination model to examine how the enhanced partner trust level can influence the forecasting evolution to improve demand forecasts’ accuracy. We estimate costs and profits from demand forecast sharing under varying trust levels between a buyer and a partner supplier and then determine the optimal level of trust for both parties to create the maximum economic value through collaborative demand forecast sharing. To assess the opportunity costs associated with …

Building Relationships As An Expat In China: An Observation On How To Successfully Build And Manage Business Relations In China, Lauren Saunders

Supply Chain Management Undergraduate Honors Theses

Since opening itself to free trade in 1979, China’s economy has doubled in size on average every 8 years. With sustained growth across forty years, China now controls the second-largest economy, just behind the United States by an ever-thinning margin. Seeing opportunity, American businesses moved operations into China immediately. As China’s economy grew, America’s reliance on supply chains across China grew. 2020 U.S. trade value in goods with China surpassed 500 billion USD, with the majority trade value coming from imports to the United States. However, starting in 2018, trade war disputes, geopolitical disruption, and the largest pandemic of the …
