On The Allocation Of Exclusive-Use Counters For Airport Check-In Queues: Static Vs. Dynamic Policies, Mahmut Parlar, Brian Rodrigues, Sharafali Moosa

Research Collection Lee Kong Chian School Of Business

In this paper we propose a static policy for the optimal allocation of a fixed number of exclusive-use check-in counters dedicated to a single flight. We first provide the motivation for considering the static policy by showing that the dynamic policy already available in the literature suffers from the curse of dimensionality. The objective is to minimize the (expected) total cost of waiting, counter operation, and passenger delay costs which we show to be convex in the number of counters allocated. In those cases where the passenger delay cost is difficult to estimate, we propose an alternative formulation and minimize …

Anticipating, Preventing, And Surviving Secondary Boycotts, Judith Schrempf-Stirling, Douglas A. Bosse, Jeffrey S. Harrison

Management Faculty Publications

Even the best stakeholder-managed firms can suffer when they become the targets of a secondary boycott, as recent headlines attest. A secondary boycott is a group’s refusal to engage a target firm with which the group has no direct dispute in an attempt to sway public opinion, draw attention to an issue, or influence the actions of a disputant. This article provides a new perspective and tools for both scholars and managers concerned with this phenomenon. Building on a stakeholder theory foundation, we examine possible actions managers can take to avoid being surprised by a secondary boycott, propose conditions that …

Riskvis: Supply Chain Visualization With Risk Management And Real-Time Monitoring, Rick S. M. Goh, Zhaoxia Wang, Xiaofeng Yin, Xiuju Fu, Loganathan Ponnanbalam, Sifei Lu, Xiaorong Li

Research Collection School Of Computing and Information Systems

With increased complexity, supply chain networks (SCNs) of modern era face higher risks and lower efficiency due to limited visibility. Hence, there is an immediate need to provide end-to-end supply chain visibility for efficient management of complex supply chains. This paper proposes a visualization scheme based on multi-hierarchical modular design and develops a supply chain visualization platform with risk management and real-time monitoring, named RiskVis, for realizing better Supply Chain Risk Management (SCRM). A Supply Chain Visualizer (SCV) with a graphical visualization platform is mounted as a part of a SCRM management decision-making dashboard and it provides senior management a …

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

In the case of Karanganyar Regency, this study identify that al­though the public aspire to have an adequate understanding about the APBD, the access for obtaining the information is very limited. Data collection methods used in this research were: (1) documents study on the Local Government Development Plan (RKPD) and the Regional Budget (APBD); (2) semi open-ended questionnaires; (3) in-depth interviews; and (4) focus group discussions. The data then analyzed using descriptive analysis and interpretive analysis methods. This paper recognizes the potency of ICT in developing the forum for public access and deliberation related to the budget information; while also …

On Properties Of Discrete (R,Q) And (S,T) Inventory Systems, Marcus Ang, Jing-Sheng Song, Mingzheng Wang, Hanqin Zhang

Research Collection Lee Kong Chian School Of Business

We consider single-item (r, q) and (s, T) inventory systems with integer-valued demand processes. While most of the inventory literature studies continuous approximations of these models and establishes joint convexity properties of the policy parameters in the continuous space, we show that these properties no longer hold in the discrete space, in the sense of linear interpolation extension and L♮-convexity. This nonconvexity can lead to failure of optimization techniques based on local optimality to obtain the optimal inventory policies. It can also make certain comparative properties established previously using continuous variables invalid. We revise these properties in the discrete space.

Plant Networks For Processing Recyclable Materials, Lieven Demeester, Mei Qi, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

We use a modified optimal market area model to examine how links between material recycling and other aspects of operations strategy can shape plant networks for the processing of recyclable materials. We characterize the complementarity of the recyclate ratio, defined as the maximum recycled content, with material versatility and miniscaling of recycling plants. We also observe that it is beneficial to coordinate investments in recycling- and production-related competencies because colocated recycling and production plants (minimills) eliminate recyclate transport. We therefore consider versatile miniplants, defined as a competency that factors in both material versatility and coordinated miniscaling of recycling and production …

Data Science In Supply Chain Management: Data-Related Influences On Demand Planning, Yao Jin

Graduate Theses and Dissertations

Data-driven decisions have become an important aspect of supply chain management. Demand planners are tasked with analyzing volumes of data that are being collected at a torrential pace from myriad sources in order to translate them into actionable business intelligence. In particular, demand volatilities and planning are vital for effective and efficient decisions. Yet, the accuracy of these metrics is dependent on the proper specification and parameterization of models and measurements. Thus, demand planners need to step away from a "black box" approach to supply chain data science. Utilizing paired weekly point-of-sale (POS) and order data collected at retail distribution …

Industrial Farm Animal Production And Livestock Associated Mrsa (Methicillin Resistant Staphylococcus Aureus)

Agribusiness Reports

Staphylococcus aureus is a leading cause of bacterial infection and is increasingly found to be resistant to antibiotic therapy. A newly described type of Methicillin Resistant Staphylococcus aureus carried by farm animals, Livestock Associated MRSA (LA-MRSA), is now causing infections in humans with and without direct livestock contact. A reduction in the non-therapeutic use of antibiotics in feed would likely reduce the capacity of industrial animal agriculture to continue to create, disseminate, and perpetuate a large reservoir of LA-MRSA on a global scale, but more fundamental changes in the way animals are raised for food may be necessary forestall a …

The Public Health Implications Of Intensive Farm Animal Production In South Asia

Agribusiness Reports

Intensive farm animal production (IFAP) is being increasingly implemented to meet the rising demand for animal source foods in South Asia. The siting of IFAP facilities in urban or peri-urban areas leads to large proximate animal populations, increasing human exposure to pollutants and pathogens. Improperly managed wastes from IFAP facilities and abattoirs can contaminate water with excess nutrients, pathogens, veterinary pharmaceuticals, antibiotics, heavy metals, and hormones, and can release ammonia, hydrogen sulfide, volatile organic compounds, bioaerosols, and particulate matter into the air compartment. The unregulated nature of IFAP in South Asia creates a risk for zoonotic transmission, including anthrax, brucellosis, …

Outsourcing Through Competition: What Is The Best Competition Parameter?, Ehsan Elahi

Management Science and Information Systems Faculty Publication Series

In this paper we consider a single buyer who wants to outsource the manufacturing of a product to N potential suppliers. The buyer’s objective is to maximize the service level she receives from the suppliers. The suppliers compete for the buyer’s demand based on a competition parameter which the buyer announces along with an allocation rule. We model each supplier as a make-to-stock queueing system. Using a simple proportional allocation function, we compare two competition parameters: service level and inventory level. We show that inventory competition creates a higher overall service level for the buyer. We also show an optimal …

Exploring Income Supplementation For Farm Sustainability, Elizabeth P. Persson

Walden Dissertations and Doctoral Studies

Sustainable farms are critical to United States’ food independence and they positively contribute to the global economy. Farms in the United States are not sustainable without profitable supplemental income. The purpose of this case study was to explore the historic profitability of farm income supplementation methods. Maslow’s hierarchy of needs theory served as the conceptual framework. A purposive sample of 25 farmers from 5 regions of the continental United States completed semistructured interviews and described their personal experiences. Archival supplemental income data came from the United States Department of Agriculture census. All the data were analyzed using coded keywords, phrases, …

Evaluations Of Port Performances From A Seaborne Cargo Supply Chain Perspective, Joyce M. W. Low, Shao Wei Lam, Loon Ching Tang, Zhang Lan

Research Collection Lee Kong Chian School Of Business

Previous research on port efficiency focuses primarily on the provider’s perspective and assumes that maximizing the output is always desirable. This paper recognizes that maximizing the final output does not necessarily guarantee an efficient system and the notion of port efficiency and service effectiveness needs to be considered from the perspectives of both the provider and the consumer of the port service. The paper proposes a network-DEA model to evaluate the performances of 30 seaports worldwide. The concurrent consideration of efficiency scores from the network-DEA model and the traditional DEA-CCR model will offer valuable insights to port operators on how …

Multi-Item Production Planning With Carbon Cap And Trade Mechanism, Bin Zhang, Liang Xu

Research Collection Lee Kong Chian School Of Business

Carbon emission control becomes a challenge in recent years, and carbon emission trading is an effective way to curb carbon emission. This paper investigates the multi-item production planning problem with carbon cap and trade mechanism, in which a firm uses a common capacity and carbon emission quota to produce multiple products for fulfilling independent stochastic demands, and the firm can buy or sell the right to emit carbon on a trading market of carbon emission. A profit-maximization model is proposed to characterize the optimization problem. The optimal policy of production and carbon trading decisions is analyzed, and an efficient solution …

How Risk Management Can Turn Into Competitive Advantage: Examples And Rationale, Ehsan Elahi

Management Science and Information Systems Faculty Publication Series

In light of the occurrence of many disruptive events since the beginning of this millennium, we can observe a change in the way risks and uncertainties are being viewed in the business world. To put this change into perspective we compare the evolution in the companies’ perception of risk management with the evolution in how companies look at their supply chain management. The main driver behind the change in the way companies view risk management is the increased level of uncertainties. There are many evidences that suggest the current very high level of volatilities in the business world is going …
