Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong YANG, Cayirli TUGBA, Mei Wan LOW 2016 Singapore Management University

Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong Yang, Cayirli Tugba, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Existing models of multi-server queues with system transience and non-standard assumptions are either too complex or restricted in their assumptions to be used broadly in practice. This paper proposes using data analytics, combining computer simulation to generate the data and an advanced non-linear regression technique called the Alternating Conditional Expectation (ACE) to construct a set of easy-to-use equations to predict the performance of queues with a scheduled start and end time. Our results show that the equations can accurately predict the queue performance as a function of the number of servers, mean arrival load, session length and service time variability ...


Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia KONG, Chung-Yee LEE, Chung-Piaw TEO, Zhichao ZHENG 2016 Adolfo Ibáñez University

Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia Kong, Chung-Yee Lee, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

We study the design of a healthcare appointment system with a single physician and a group of patients whose service durations are stochastic. The challenge is to find the optimal arrival sequence for a group of mixed patients such that the expected total cost of patient waiting time and physician overtime is minimized. While numerous simulation studies report that sequencing patients by increasing order of variance of service duration (Smallest-Variance-First or SVF rule) performs extremely well in many environments, analytical results on optimal sequencing are known only for two patients. In this paper, we shed light on why it is ...

Mentoring Undergraduate Research In Education And Business: Transformation In Global And Local Communities, Hulya Julie Yazici, Tunde Szecsi 2016 Florida Gulf Coast University

Mentoring Undergraduate Research In Education And Business: Transformation In Global And Local Communities, Hulya Julie Yazici, Tunde Szecsi

Florida Statewide Symposium – Engagement in Undergraduate Research

The purpose of this presentation is to highlight avenues toward undergraduate scholarship in education and business. The common theme of these initiatives is the transformative learning which students experienced in local and global communities. In education, the examples include a course-embedded action research with community service, and autoethnography in which students analyzed their experiences abroad to uncover the process of transformation. In business, students worked on a semester long project in quality management collaborating with a local health equipment manufacturer. The systematic guidance of the business and continuous feedback of the instruction, resulted in full transformation of student learning.

College Students Use Social Networking Sites For Sharing With Friends, But Guess Who Else Is Looking?, Elizabeth C. Alexander, Fred Mader, Deanna Mader 2016 Marshall University

College Students Use Social Networking Sites For Sharing With Friends, But Guess Who Else Is Looking?, Elizabeth C. Alexander, Fred Mader, Deanna Mader

Atlantic Marketing Journal

Abstract - Jobvite, a recruiting platform for the social web, reports from their annual 2012 survey of recruiters that 92% of U.S. companies are using social networking sites (SNS) for hiring purposes (Jobvit, 2012). Career Builder reported in 2009 that 45% of employers were using SNS to screen and research applicants (CareerBuilder, 2009). It is important that faculty and support staff working to place students, and the students themselves, understand the developments and practices in the use of social networking sites for job search and recruiting and the best methods, as well as detriments when marketing themselves. This study examines ...


Using Focus Groups And Correspondence Analysis To Explore The Relationship Between Millennials’ Online Behavior And Their Opinions Of Online Reviews, James E. Stoddard, Michael Dotson, Neel Das 2016 Appalachian State University

Using Focus Groups And Correspondence Analysis To Explore The Relationship Between Millennials’ Online Behavior And Their Opinions Of Online Reviews, James E. Stoddard, Michael Dotson, Neel Das

Atlantic Marketing Journal

This paper explores the relationship between millennials’ online behavior and their opinions of online reviews via the use of focus groups and correspondence analysis. The proposition was that millennials’ online behavior (including search behavior) is likely to have an effect on how they view online reviews. The correspondence analysis results suggest that millennials who spend more time online peruse a greater number of products. Further, relationships were found between millennials’ time online and factors influencing review trustworthiness as well as millennials’ time online and factors affecting review memorability. It is noteworthy to suggest that focus group analysis can be enhanced ...

Volume And Cost Implications Of Product Portfolio Complexity, Mark A. Jacobs 2016 University of Dayton

Volume And Cost Implications Of Product Portfolio Complexity, Mark A. Jacobs

Mark Jacobs

Business leaders are concerned about the impacts of increasing levels of product portfolio complexity since many sense that complexity related costs such as order management, procurement, and inventory threaten to undermine operational efficiencies and consume profits. Even so, managers do not fully understand the extent and breadth of the impacts of product portfolio complexity. A more complete understanding of the operational effects of product portfolio complexity is lacking partially because researchers have not yet offered a robust theoretical perspective or studied it in a focused controlled way; until now. Herein, measures of product portfolio complexity are developed and related to ...


Procurement Fraud, Lisa McNamee 2016 La Salle University

Procurement Fraud, Lisa Mcnamee

Economic Crime Forensics Capstones

The 2016 Global Economic Crime Survey conducted by PricewaterhouseCoopers LLP (2016), states that twenty-two percent of companies have experienced procurement fraud. The statistics have actually decreased since 2014 when twenty-seven percent of companies had experienced procurement fraud. However, procurement fraud is still one of the most costly fraudulent schemes. Despite the reduction, the Department of Defense continues to experience large procurement fraud cases, both in number and dollar value. A recent example is the Supreme Foodservice fraud case, which cost the Defense Logistics Agency $757 million dollars in fraudulent charges. (Jahner, 2014) The Department of Defense Office of Inspector General ...


Contracting, Logistics, Reverse Logistics: The Project, Program And Portfolio Approach, Robert Lee Gordon 2016 American Public University System

Contracting, Logistics, Reverse Logistics: The Project, Program And Portfolio Approach, Robert Lee Gordon

ePress Monographs

Contracting, logistics, and reverse logistics are intertwined with the project management, program management, and portfolio management disciplines. In recent years, organizations have started to offer certifications into the strategic areas of program and portfolios. Contracting, logistics, and reverse logistics are strategic opportunities for companies. For this reason, three programs benefit from an overlapping text that demonstrates how project, program, and portfolio management (PPPM) drives better strategy. Ultimately, successful strategy leads to increased value and the difficult topics of ethics, culture, relationships, and a company’s return on investment (ROI). This book is divided into 9 sections and a total of ...


First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle 2016 United States Air Force San Antonio Military Medical Center

First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle

Journal of Patient-Centered Research and Reviews

Purpose

Operating room delays decrease health care system efficiency and increase costs. To improve operating room efficiency in our system, we retrospectively investigated delay frequencies, causes and costs.

Methods

We studied all first-of-the-day nonemergent surgical cases performed at three high-volume urban hospitals of a large health system from July 2012 to November 2013. Times for patient flow from arrival to procedure start and documented reasons for delay were obtained from electronic medical records. Delay was defined as patient placement in the operating room later than scheduled surgery time. Effects of patient characteristics, late patient arrival to the hospital, number of ...


How Cios Overcome The Competing Values Challenge: Irish Cios’ Perspectives, Harvey Enns, Dean B. McFarlin, Paul B. Sweeney 2016 University of Dayton

How Cios Overcome The Competing Values Challenge: Irish Cios’ Perspectives, Harvey Enns, Dean B. Mcfarlin, Paul B. Sweeney

Paul B. Sweeney

Competing values are a fact of organizational life. However, there are gaps in our understanding about how these opposing beliefs hinder influence processes. This article draws on interview data to demonstrate how Irish Chief Information Officers (CIOs) are able to convince their colleagues to support new projects within their firms in the face of competing values. Focused interviews were used to explore the influence process and the competing values phenomenon, since this type of research is at an early stage and qualitative methods and analysis serve as a rich source of theory development.

The data showed that the CIOs who ...


Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman 2016 University of Dayton

Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman

Michael F. Gorman

In the transportation industry, companies position rolling stock where it is likely to be needed in the face of a pronounced weekly cyclical demand pattern in orders.

Strategic policies based on assumptions of repetition of cyclical weekly patterns set rolling stock targets; during tactical execution, a myriad dynamic influences cause deviations from strategically set targets. We find that optimal strategic plans do not agree with results of tactical modeling; strategic results are in fact suboptimal in many tactical situations. We discuss managerial implications of this finding and how the two modeling paradigms can be reconciled.


Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman 2016 University of Dayton

Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman

Michael F. Gorman

We propose improved pricing and market mix can improve the profitability of the freight transportation provider through the reduction of equipment repositioning costs. We hypothesize that because of complexities surrounding pricing and equipment repositioning costing, existing pricing strategies in freight transportation fail to fully consider these costs. We test this hypothesis in an applied setting in which Monte Carlo simulation captures the stochasticity of market conditions inherent in the problem. We use a heuristic to improve the nondifferentiable, discontinuous objective function.

Our results from test cases show with high confidence that current prices are not optimal, as indicated by a ...
