How To Optimize Storage Classes In A Unit-Load Warehouse, Marcus Ang, Yun Fong Lim Oct 2019

How To Optimize Storage Classes In A Unit-Load Warehouse, Marcus Ang, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

We study a problem of optimizing storage classes in a unit-load warehouse such that the total travel cost is minimized. This is crucial to the operational efficiency of unit-load warehouses, which constitute a crit- ical part of a supply chain. We propose a novel approach called the FB method to solve the problem. The FB method is suitable for general receiving-dock and shipping-dock locations that may not coincide. The FB method first ranks the locations according to the frequencies that they are visited, which are estimated by a linear program based on the warehouse’s layout as well as the ...


The Role Of Prior Sales Experience Of Buyers And Duration In Buyer-Seller Relationships, Scott C. Ambrose, Nwamaka A. Anaza, Brian N. Rutherford Jun 2019

The Role Of Prior Sales Experience Of Buyers And Duration In Buyer-Seller Relationships, Scott C. Ambrose, Nwamaka A. Anaza, Brian N. Rutherford

Scott C. Ambrose

This paper examines the impact that a buyer’s prior sales experience and the duration of the buyer-salesperson relationship has on the satisfaction and commitment linkages established within the literature. First, two key facets of satisfaction (social and economic) are linked to buyer’s commitment to the salesperson. Next, buyer-salesperson relationship duration is examined as an influencer between the satisfaction and commitment linkages. Following this, the study shifts its focus to examine if and how buyers with prior sales experience view the buyer-salesperson relationship different than buyers without prior sales experience. Findings of the study highlight the importance of developing ...

Global Value Chains And The Cptpp, Pao-Li Chang, Tran Bao Phuong Nguyen Jun 2019

Global Value Chains And The Cptpp, Pao-Li Chang, Tran Bao Phuong Nguyen

SMU Economics and Statistics Working Paper Series

The CPTPP, or the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, is an example of a “mega-regional” free trade agreement, whose provisions on the rules of origin and trade facilitation can have potentially large impacts on the CPTPP-wide supply chains. In this paper, we investigate whether the CPTPP members are key upstream and downstream trade partners to each other in the global value chains. We develop formulas of bilateral upstreamness and downstreamness, based on the gross-export decomposition framework of Koopman, Wang and Wei (2014) and Borin and Mancini (2017). We demonstrate how the decomposition of gross exports can be used ...


Intra-Organizational Communication, Understanding, And Process Diffusion In Logistics Service Providers, Scott J. Grawe, Peter M. Ralston May 2019

Intra-Organizational Communication, Understanding, And Process Diffusion In Logistics Service Providers, Scott J. Grawe, Peter M. Ralston

Scott Grawe

Purpose – The purpose of this paper is to investigate, using survey data, how a firm may be able to leverage innovation or processes specifically developed for one customer across its entire customer network using onsite, or implanted, employees.

Design/methodology/approach – Data collected from a survey of 309 implanted logistics service provider (LSP) representatives are analyzed using structural equation modeling.

Findings – The findings show that intra-organizational task interdependence and face-to-face communication can lead to a greater understanding of firm processes developed for specific customers and greater diffusion of these new processes to other customers. Rather than separating customers that require ...


Demand Forecasting: An Open-Source Approach, Murtada Shubbar, Jared Smith May 2019

Demand Forecasting: An Open-Source Approach, Murtada Shubbar, Jared Smith

SMU Data Science Review

In this paper, we compare demand forecasting methods used by the supply chain department at Bilports to open-source forecasting methods. The design and implementation of the open-source forecasting system also attempts to use several external datasets such as consumer sentiment, housing permit starts, and weather to improve prediction quality. Additionally, the performance of the forecast is evaluated by the reduction of shipment lead times from China, the company’s primary vendor. The objective of our paper is to improve Bilports’s forecasting capabilities. The primary motivation of this paper is to increase forecasting accuracy and identify the weaknesses of the ...


Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren May 2019

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Theses and Dissertations

According to USDA FAS, in 2017, the US was the largest broiler-producing country with 18.696 million metric tons and the second largest exporter of broiler products with 3.075 million metric tons (Brazil is the largest exporter with 3.847 million metric tons). Thus, around 83% of US production is consumed domestically. According to USITC, chickens are the most important protein source in the US, and Americans consume more chicken per capita than any other country. However, while the broiler industry is a key segment of US agriculture, it is underserved by large-scale supply-chain and trade models.

In this ...


Crop Planning In Sustainable Agriculture: Dynamic Farmland Allocation In The Presence Of Crop Rotation Benefits, Onur Boyabatli, Javad Nasiry, Yangfang Helen Zhou May 2019

Crop Planning In Sustainable Agriculture: Dynamic Farmland Allocation In The Presence Of Crop Rotation Benefits, Onur Boyabatli, Javad Nasiry, Yangfang Helen Zhou

Research Collection Lee Kong Chian School Of Business

This paper examines crop planning decision in sustainable agriculture---that is, how to allocate farmland among multiple crops in each growing season when the crops have rotation benefits across growing seasons. We consider a farmer who periodically allocates the farmland between two crops in the presence of revenue uncertainty where revenue is stochastically larger and farming cost is lower when a crop is grown on rotated farmland (where the other crop was grown in the previous season). We characterize the optimal dynamic farmland allocation policy and perform sensitivity analysis to investigate how revenue uncertainty of each crop affects the farmer's ...


Disruption Risk Mitigation In Supply Chains: The Risk Exposure Index Revisited, Sarah Yini Gao, David Simchi-Levi, Chung-Piaw Teo, Zhenzhen Yan May 2019

Disruption Risk Mitigation In Supply Chains: The Risk Exposure Index Revisited, Sarah Yini Gao, David Simchi-Levi, Chung-Piaw Teo, Zhenzhen Yan

Research Collection Lee Kong Chian School Of Business

Simchi-Levi et al. (2014, 2015a) proposed a novel approach using the Time-To-Recover (TTR) parameters to analyze the Risk Exposure Index (REI) of supply chains under disruption. This approach is able to capture the cascading effects of disruptions in the supply chains, albeit in simplified environments -- TTRs are deterministic, and at most one node in the supply chain can be disrupted. In this paper, we proposed a new method to integrate probabilistic assessment of disruption risks into the REI approach and measure supply chain resiliency by analyzing the Worst-case CVaR (WCVaR) of total lost sales under disruptions.We show that the ...


Combating Child Labor: Incentives And Information Disclosure In Global Supply Chains, Soo-Haeng Cho, Xin Fang, Sridhar Tayur, Ying Xu May 2019

Combating Child Labor: Incentives And Information Disclosure In Global Supply Chains, Soo-Haeng Cho, Xin Fang, Sridhar Tayur, Ying Xu

Research Collection Lee Kong Chian School Of Business

Problem definition: We investigate multinational firms’ inspection and pricing strategies to address the challenges of combating child labor in global supply chains. We also examine how several factors (such as information disclosure, goodwill loss, inspection cost, external monitoring by nongovernmental organizations (NGOs), and penalty scheme) affect firms’ incentives to use different strategies to combat child labor. Academic/practical relevance: Nearly 200 million children are engaged in child labor, many in developing countries that are part of the supply base of global manufacturing networks. However, there has been little research on evaluating the impact of firms’ strategies and NGOs’ initiatives on ...


Managing Wind-Based Electricity Generation In The Presence Of Storage And Transmission Capacity, Yangfang Zhou, Alan Scheller-Wolf, Nicola Secomandi, Stephen Smith Apr 2019

Managing Wind-Based Electricity Generation In The Presence Of Storage And Transmission Capacity, Yangfang Zhou, Alan Scheller-Wolf, Nicola Secomandi, Stephen Smith

Research Collection Lee Kong Chian School Of Business

We investigate the management of a merchant wind energy farm co‐located with a grid‐level storage facility and connected to a market through a transmission line. We formulate this problem as a Markov decision process (MDP) with stochastic wind speed and electricity prices. Consistent with most deregulated electricity markets, our model allows these prices to be negative. As this feature makes it difficult to characterize any optimal policy of our MDP, we show the optimality of a stage‐ and partial‐state‐dependent‐threshold policy when prices can only be positive. We extend this structure when prices can also be ...


Strategies To Reduce Employee Turnover In Clinical Logistics, Brenda Simon Mar 2019

Strategies To Reduce Employee Turnover In Clinical Logistics, Brenda Simon

Brenda Simon

Clinical supply chain managers who do not apply effective employee turnover strategies could negatively affect team performance, employee morale, employee well-being, patient outcomes, productivity, profitability, and the sustainability of organizational activities. The purpose of this multiple case study was to explore strategies that supply chain managers used to decrease employee turnover in clinical logistics organizations. The targeted population consisted of 6 clinical logistics supply chain managers working in 6 community hospitals located in Maryland with experience implementing successful strategies to decrease employee turnover. The servant leadership theory served as the study’s framework. Data collection included semistructured interviews and a ...


Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Helen Yangfang Zhou Mar 2019

Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Helen Yangfang Zhou

Research Collection Lee Kong Chian School Of Business

This chapter develops a theoretical basis for understanding the trade-offs facing a farmer for allocating his farmland among several crops over multiple growing seasons. Specifically, we focus on the farmland allocation among two cash crops (corn and soybeans) and letting the farmland lay fallow to rejuvenate the soil and increase the revenue for the crop grown on this farmland in the subsequent seasons. In each growing period, the farmer chooses the allocation in the presence of revenue uncertainty for each cash crop, and crop rotation benefits across periods, where revenue is stochastically larger and farming cost is lower when a ...


Encouraging Help Across Projects, Pascale Crama, Fabian J. Sting, Yaozhong Wu Mar 2019

Encouraging Help Across Projects, Pascale Crama, Fabian J. Sting, Yaozhong Wu

Research Collection Lee Kong Chian School Of Business

Companies struggle with timely project execution despite employing sophisticated management methods. Although help across projects is critical for time performance, it has not been explicitly incorporated into project management (PM) systems. We model a PM system, based on an innovative real-life practice, that both incorporates and shapes project managers’ helping behavior. A help process is at the core of this system, in which project managers may ask for and provide help while top management facilitates such exchanges. We find that companies should take a nuanced approach when designing help exchange and time-based incentives in tandem. A company that faces high ...

Effects Of Rescheduling On Patient No-Show Behavior In Outpatient Clinics, Jiayi Liu, Jingui Xie, Kum Khiong Yang, Zhichao Zheng Feb 2019

Effects Of Rescheduling On Patient No-Show Behavior In Outpatient Clinics, Jiayi Liu, Jingui Xie, Kum Khiong Yang, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

We study the effects of rescheduling on no-show behavior in an outpatient appointment system for both new and follow-up patients. Previous literature has primarily focused on new patients and investigated the role of waiting time on no-show probability. We offer a more nuanced understanding of this costly phenomenon. Using comprehensive clinical data, we demonstrate that for follow-up patients, their no-show probability decreases by 10.9 percentage points if their appointments were rescheduled at their own request, but increases by 6.2 percentage points if they were rescheduled by the clinic. New patients, in contrast, are more concerned about waiting time ...

Supply Chain Integration, Learning, And Agility: Effects On Performance, Habibullah Khan, Joel D. Wisner

Marketing and International Business Faculty Publications

This study examines the interrelationships among supply chain integration, learning, agility and organizational performance. Survey data were collected from 257 publicly-owned companies in Pakistan, and the hypothesized framework was tested using a structural equation model. It was found that supply chain integration had a significant impact on external and internal learning. Additionally, supply chain integration was found to have an insignificant impact on firm performance and supply chain agility. Finally, internal learning was found to have an insignificant impact on supply chain agility, but a significant direct impact on firm performance, while external learning had an insignificant impact on firm ...


The Effectiveness Of Collaboration Within Supply Chain Management: A Case Study Of Adidas Group, Daniel Carr Jan 2019

The Effectiveness Of Collaboration Within Supply Chain Management: A Case Study Of Adidas Group, Daniel Carr

CMC Senior Theses

For a multi-national company like Adidas, supply chain management is one of the most crucial aspects of business operations. Products cannot be sold unless Adidas’s supply chain is well-managed and efficient, and public perception of a brand/company is critical to success.

This case study analyzes the effectiveness of Adidas's distinct “collaborative approach” to supply chain management, which is characterized by not only monitoring and auditing suppliers, but also training them to make Adidas’s standards their own and approaching suppliers with the intention of building long-term relationships where the suppliers can become self-sufficient.

This study reviews the ...


Halal Accreditation And Certification In A Non-Muslim Country Setting: Insights From Australia Halal Meat Supply Chain, Mohd Hafiz Zulfakar, Caroline Chan, Ferry Jie, Veera Pandiyan Kaliani Sundram Jan 2019

Halal Accreditation And Certification In A Non-Muslim Country Setting: Insights From Australia Halal Meat Supply Chain, Mohd Hafiz Zulfakar, Caroline Chan, Ferry Jie, Veera Pandiyan Kaliani Sundram

ECU Publications Post 2013

It is a known fact that most halal food products, especially meat are now sourced from various part of the world and the majority of halal food exporters/producers come from non-Muslim countries. This has led to growing concerns from the halal consumers, especially the Muslim communities with regards to whether the halal status of these food products can really be guaranteed throughout the supply chain in these countries and whether the halal foods claimed are authentic. This study aims to better understand the current halal meat certification in Australia, a predominantly non-Muslim country. By adopting a case study approach ...

A Decade Of Progress Toward Ending The Intensive Confinement Of Farm Animals In The United States, Sara Shields, Paul Shapiro, Andrew N. Rowan Dec 2018

A Decade Of Progress Toward Ending The Intensive Confinement Of Farm Animals In The United States, Sara Shields, Paul Shapiro, Andrew N. Rowan

Andrew N. Rowan, D.Phil.

In this paper, the Humane Society of the United States (HSUS) farm animal protection work over the preceding decade is described from the perspective of the organization. Prior to 2002, there were few legal protections for animals on the farm, and in 2005, a new campaign at the HSUS began to advance state ballot initiatives throughout the country, with a decisive advancement in California (Proposition 2) that paved the way for further progress. Combining legislative work with undercover farm and slaughterhouse investigations, litigation and corporate engagement, the HSUS and fellow animal protection organizations have made substantial progress in transitioning the ...

A Model For Better Social Project Management, Brenda Massetti Nov 2018

A Model For Better Social Project Management, Brenda Massetti

Journal of Vincentian Social Action

With environmental degradation and other social ills on the rise, demand for businesses to perform social action is growing (Robertson, 2014). Yet, most Commercial enterprises take a diminutive view of social projects, and many Social enterprises flounder in the harsh realities of commerce (Austin, Stevenson, and Wei-Killern, 2012). To improve all enterprises’ social performance, the paper introduces the Social Project Grid, a dual-factor assessment tool which prioritizes social projects for better managerial oversight. In specific, it compares social projects on their Resource Use and Outcome Clarity to highlight which projects are successful and which are in trouble. Not only is ...
