Head Over Heels: Women In Supply Chain Management, Mary Margaret Mobley

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Being a woman in the Supply Chain Management major, I have seen the challenges females face in a male-dominated field. Just why is it that we see so few women in executive roles in the Supply Chain field? Is it because of the gender challenges, or is there another underlying issue that is causing the lack of women in upper-level Supply Chain roles? Through this research study, twelve female participants will tell about their experiences being an entry-level woman in Supply Chain field. These challenges will help to determine if these entry-level challenges are the reason why women are either …

Emerging Research Institutions' Technology Transfer Supply Chain Networks' Sustainability Budget Resource Planning Tool Development, Clovia Hamilton

Winthrop Faculty and Staff Publications

Emerging Research Institution (ERls) can benefit from patent licensing revenues from the transfer f patented technologies into the commercial marketplace because these added revenues can help research institutions become more sustainable financially. However, many ERls struggle to succeed in technology transfer. This study describes the development of a university technology transfer supply chain network sustainability tool that private and public ERls can use to become more self-reliant financially. Historically black colleges and universities (HBCUs) are ERls and are used as a case study. HBCUs lag behind their peer non-HBCUs because historically they have been under-served and were originally established largely …

Call Center Experience Optimization: A Case For A Virtual Predictive Queue, William Pugh

Theses & Dissertations

The evolution of the call center into contact centers and the growth of their use in providing customer-facing service by many companies has brought considerable capabilities in maintaining customer relationships but it also has brought challenges in providing quality service when call volumes are high. Limited in their ability to provide service at all times to all customers, companies are forced to balance the costs associated with hiring more customer service representatives and the quality of service provided by a fewer number. A primary challenge when there are not enough customer service representatives to engage the volume of callers in …

The Interaction Between Operational Flexibility And Financial Flexibility, Onur Boyabatli, Tiecheng Leng

Research Collection Lee Kong Chian School Of Business

This paper examines the interaction between operational flexibility and financial flexibility in a multi-product business unit that makes operational decisions based on financial resources provided by its parent company (or headquarters). We capture operational flexibility through investment in flexible technology and financial flexibility through higher availability of financial resources. We consider the flexible-versus-dedicated technology choice and capacity investment decisions of a two-product business unit under demand uncertainty in the presence of budget constraints. The unit operates under a capital budget for financing the capacity investment, and an operating budget, which is uncertain in the capacity investment stage, for financing the …

Technical Note—On The Relation Between Several Discrete Choice Models, Guiyun Feng, Xiaobo Li, Zizhuo Wang

Research Collection Lee Kong Chian School Of Business

In this paper, we study the relationship between several well known classes of discrete choice models, i.e., the random utility model (RUM), the representative agent model (RAM), and the semiparametric choice model (SCM). Using a welfare-based model as an intermediate, we show that the RAM and the SCM are equivalent. Furthermore, we show that both models as well as the welfare-based model strictly subsume the RUM when there are three or more alternatives, while the four are equivalent when there are only two alternatives. Thus, this paper presents a complete picture of the relationship between these choice models.

Inventory Management Based On Target-Oriented Robust Optimization, Yun Fong Lim, Chen Wang

Research Collection Lee Kong Chian School Of Business

We propose a target-oriented robust optimization approach to solve a multi-product, multi-period inventory management problem subject to ordering capacity constraints. We assume the demand for each product in each period is characterized by an uncertainty set, which depends only on a reference value and the bounds of the demand. Our goal is to find an ordering policy that maximizes the sizes of all the uncertainty sets such that all demand realizations from the sets will result in a total cost lower than a pre-specified cost target. We prove that a static decision rule is optimal for an approximate formulation of …

Capacity Management In Agricultural Commodity Processing And Application In The Palm Industry, Onur Boyabatli, Jason Quang Dang Nguyen, Tong Wang

Research Collection Lee Kong Chian School Of Business

This paper examines the capacity investment decisions of a processor that uses a commodity input to produce both a commodity output and a byproduct in the context of agricultural industries. We employ a multi-period model to study the optimal one-time processing and (output) storage capacity investment decisions---in addition to the periodic processing and inventory decisions---when both input and output spot prices as well as production yield are uncertain. We characterize the optimal decisions and perform sensitivity analysis to investigate how spot price uncertainty affects the processor's optimal capacity and profitability. Using a calibration based on the palm industry, we study …

Couples Sleeping Apart--Separate Master Bedrooms And The Impact On The Real Estate And Related Markets, John E. Crawford

Atlantic Marketing Journal

Sleeping is a fundamental individual human need. However, most adults fulfill this need by sleeping with a partner, a behavior particularly true for married couples. A trend of couples choosing to sleep apart has emerged in recent years. For reasons practical and personally beneficial or preferred, a growing number of couples are choosing to have a home with two master bedrooms--one for him and one for her, each furnished according to the needs and tastes of the partners. Thus, some homes are being built with two master bedrooms, others are being modified to have two master bedrooms, and new empty …

Theory And Practice Of Supply Chain Synchronization, Michael Prokle

Doctoral Dissertations

In this dissertation, we develop strategies to synchronize component procurement in assemble-to-order (ATO) production and overhaul operations. We focus on the high-tech and mass customization industries which are not only considered to be very important to create or keep U.S. manufacturing jobs, but also suffer most from component inventory burden. In the second chapter, we address the deterministic joint replenishment inventory problem with batch size constraints (JRPB). We characterize system regeneration points, derive a closed-form expression of the average product inventory, and formulate the problem of finding the optimal joint reorder interval to minimize inventory and ordering costs per unit …

Contracts To Promote Optimal Use Of Optional Diagnostic Tests In Cancer Treatment, Salar Ghamat, Gregory S. Zaric, Hubert Pun

Business Publications

In this study, we examine performance-based payment contracts to promote the optimal use of an optional diagnostic test for newly diagnosed cancer patients. Our work is inspired by three trends: tremendous increases in the cost of new, advanced cancer drugs; development of new diagnostic tests to allow physicians to tailor treatment to patients; and changes in healthcare funding models that reward quality care. We model the interaction between two parties—a healthcare payer and an oncologist, in which the oncologist has private information about patients’ characteristics (adverse selection) and the payer does not know whether the oncologist takes the optimal course …

Geopolitics Of Rare Earth Elements, Bert Chapman

Libraries Faculty and Staff Presentations

Rare earth elements (REE) contain unique chemical physical properties such as lanthamum, are found in small concentrations, need extensive precise properties to separate, and are critical components of modern technologies such as laser guidance systems, personal electronics such as IPhones, satellites, and military weapons systems as varied as Virginia-class fast attack submarines, DDG-51 Aegis destroyers, the F-35 Joint Strike Fighter, and precision guided munitions. The U.S. has some rare earth resources, but is heavily dependent on access to them from countries as varied as Afghanistan, Bolivia, and China. Losing access to these resources would have significant adverse economic, military, and …

Hbcu Technology Transfer Supply Chair Networks’ Sustainability: Budget Resource Planning Tool Development, Clovia Hamilton

Winthrop Faculty and Staff Publications

This study describes the development of a university technology transfer supply chain network sustainability tool that Historically Black Colleges and Universities (HBCUs) can use to become more self-reliant financially. HBCUs lag behind their peer non-HBCUs because historically they have been under-served and were originally established largely as teaching and blue collar trade schools. Increased involvement in research oriented activities such as technology transfer will likely enable HBCUs to grow into new or stronger research institutions. The literature review revealed several problem areas with non-HBCUs university technology transfer include a resource planning issues. These problem areas for non-HBCUs would be challenging …

Transshipment Hub Selection From A Shipper’S And Freight Forwarder’S Perspective, Gang Chen, Waiman Cheung, Sung-Chi Chu, Liang Xu

Research Collection Lee Kong Chian School Of Business

Transshipment hub selection becomes increasingly important to the global logistics community. From the perspectives of shippers and freight forwarders, a selection must align with cost control strategy and sustain service reliability across cooperative service providers. This paper assesses the selection with the options of both sea and air transports, and from the influence of country of origin of the company. Critical factors of transshipment hub selection, both qualitative and quantitative, are identified through focus group discussions. Relative importance of these factors is determined based on collective views of logistics stakeholders. The competitiveness of transshipment hubs is then assessed using an …

Identification Of Reverse Engineering Candidates Utilizing Machine Learning And Aircraft Cannibalization Data, Marc Banghart

International Journal of Aviation, Aeronautics, and Aerospace

As military aircraft continue to remain in service and age, cannibalization of parts is increasing. Proactive identification of parts that are at high risk for cannibalization will inform engineering processes such as reverse engineering, thus allowing potentially reducing lead time to develop new parts. The research objective was to develop a causal structure that can be used for prediction of when cannibalization actions may occur. Bayesian networks allow encoding of causality between various descriptive features given a data set. The method utilized a tabu search algorithm, identified the underlying causal structure and the associated node probabilities. The method is then …

Research Collection Lee Kong Chian School Of Business

The advent of big data has created opportunities for firms to customize their products and services to unprecedented levels of granularity. Using big data to personalize an offering in real time, however, remains a major challenge. In the mobile advertising industry, once a customer enters the network, an ad-serving decision must be made in a matter of milliseconds. In this work, we describe the design and implementation of an ad-serving algorithm that incorporates machine-learning methods to make personalized ad-serving decisions within milliseconds. We developed this algorithm for Vungle Inc., one of the largest global mobile ad networks. Our approach also …

Performance Of Cellular Bucket Brigades With Hand-Off Times, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

A cellular bucket brigade is a way to coordinate workers along an aisle with work content on both sides. Each worker in a cellular bucket brigade works on one side of the aisle when he proceeds in one direction, and he works on the other side when he proceeds in the reverse direction. Although the cellular bucket brigade eliminates the unproductive walk-back, it requires more hand-offs to assemble a product than a traditional (serial) bucket brigade. These hand-offs may waste significant production capacity as each of them requires an exchange of work, which can be complicated and time-consuming in practice. …
