Capacity Planning With Financial And Operational Hedging In Low‐Cost Countries, Lijian Chen, Shanling Li, Letian Wang

MIS/OM/DS Faculty Publications

The authors of this paper outline a capacity planning problem in which a risk-averse firm reserves capacities with potential suppliers that are located in multiple low-cost countries. While demand is uncertain, the firm also faces multi-country foreign currency exposures. This study develops a mean-variance model that maximizes the firm’s optimal utility and derives optimal utility and optimal decisions in capacity and financial hedging size. The authors show that when demand and exchange rate risks are perfectly correlated, a risk- averse firm, by using financial hedging, will achieve the same optimal utility as a risk-neutral firm. In this paper as well, …

Designing Efficient Infrastructural Investment And Asset Transfer Mechanisms In Humanitarian Supply Chains, Shantanu Bhattacharya, Sameer Hasija, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

We analyze the efficacy of different asset transfer mechanisms and provide policy recommendations for the design of humanitarian supply chains. As a part of their preparedness effort, humanitarian organizations often make decisions on resource investments ex ante because doing so allows for rapid response if an adverse event occurs. However, programs typically operate under funding constraints and donor earmarks with autonomous decision-making authority resting with the local entities, which makes the design of efficient humanitarian supply chains a challenging problem. We formulate this problem in an agency setting with two independent aid programs, where different asset transfer mechanisms are considered …

Integrating Simulation Modelling And Value Stream Mapping For Leaner Capacity Planning Of An Emergency Department, Esmat Swallmeh, Ayman Tobail, Waleed Abo-Hamad, James Gray, Amr Arisha

Conference papers

Recently, the application of lean thinking in healthcare has grown significantly in response to rising demand, caused by population growth, ageing and high expectations of service quality. However, insufficient justifications and lack of quantifiable evidence are the main obstacles to convince healthcare executives to adopt lean philosophies. This paper presents a real application of the successful implementation of a methodology that integrates Value Stream Mapping (VSM) and simulation modelling to improve an emergency department (ED) of a University hospital in Dublin. Appling lean approach in operations will minimize the patient waiting time and improve service time. VSM points out to …

Optimization Of Resources To Improve Patient Experience In The New Emergency Department Of Mater Hospital Dublin, Heba Habib, Waleed Abo-Hamad, Amr Arisha

Conference papers

Healthcare systems globally are facing capacity issues due to the increased demand of health services, the high cost of resources and the level of quality anticipated of service providers. Emergency Departments (ED) are the most pressurized unit in healthcare systems due to uncertainty in demand and limited resources allocated. Mater Hospital (one of leading hospitals) in Dublin has built a new (state-of-the-art) unit for ED yet faced an issue in resourcing the unit to optimize performance. This paper presents an integrated solution to optimize the capacity of the new ED before opening to public and examine improvement interventions in the …

Chain Liability In Multitier Supply Chains? Responsibility Attributions For Unsustainable Supplier Behavior, Julia Hartmann, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

When it becomes publicly known that products are associated with suppliers that engage in unsustainable behaviors, consumers protest, as Nestlé, Zara, and Kimberly Clark, among others, have learned. The phenomenon by which consumers hold firms responsible for the unsustainable behavior of their upstream partners suggests the notion of “chain liability.” This study aims to generate insights into the antecedents and consequences of such consumer responsibility attributions. Using data from four vignette-based survey experiments, the authors find that the chain liability effect increases if an environmental degradation incident (1) results from supplier behavior rather than force majeure, (2) results from a …

Impact Of Component Supplier Branding On Profitability, Stefan Worm, Rajendra K. Srivastava

Research Collection Lee Kong Chian School Of Business

In recent years, many business-to-business (B2B) component supplier (CS) firms have added branding to their marketing toolbox. By extending the logic of ingredient branding to B2B components, they aim to create “pull” from B2B end customers by building a strong CS brand image among their customers' customers. In contrast with the established “push” approach of building strong relationships with original equipment manufacturers (OEMs), it is unclear whether and under which conditions CS branding is a worthy strategy. On the one hand, anecdotal evidence suggests that suppliers can leverage strong CS brand image in negotiations with increasingly powerful OEMs to enhance …

Cellular Bucket Brigades On U-Lines With Discrete Work Stations, Yun Fong Lim, Yue Wu

Research Collection Lee Kong Chian School Of Business

It is challenging to maximize and maintain productivity of a U-line with discrete stations under the impact of variability. This is because maximizing productivity requires assigning workers to suitable tasks and maintaining productivity requires sufficient flexibility in task assignment to absorb the impact of variability. To achieve this goal, we propose an operating protocol to coordinate workers on the U-line. Under the protocol the system can be configured such that its productivity is maximized. Workers are allowed to dynamically share work so that the system can effectively absorb the impact of variability. Analysis based on a deterministic model shows that …

Perceived Service Quality Of Electricity Supply In Nigeria: A Survey Of Manufacturers In Kakuri Industrial Estate, Kaduna, Abdulsalam Dauda, Mohammed Abubakar Mawoli, Abdullahi Yusuf Babandako

Business Review

Manufacturing firms require adequate business support facilities in order to operate optimally and contribute to the economic growth of nations. The quality of the business support services is as important as their availability or provision. While it has been established that the existing business support services in Nigeria are inadequate, the quality of the existing business support facilities is unknown. Based on the contention that quality is determined by the user or customer, this study evaluates the service quality of electricity services in Nigeria from manufacturers’ perception. The entire population of the study constituting the general managers and assistant managers …

Navigating The Flow Of Value Streams To The Seas Of Collection Management, Acquisitions, And Preservation, Greg W. Voelker, Richard J. W. Zwiercan, Michael Frazier

Charleston Library Conference

Our process of repairing damaged items had no clear ownership and an ever growing amorphous backlog consisting of approximately 2,800 items at the start of the process review. This backlog continues to hinder access to materials in the collection. We are currently in multistage process review which incorporates Lean methodologies to improve workflow across a number of departments. At the core of these improvements is gathering data to measure current levels of work. From that perspective, we can see where value is needed in the workflows, including areas of collection access, level of repair needed, item replacement/weeding, and meeting user/stakeholder …

Assessing Customer Service In Airports – Models From The Uae, Aman Gupta, Mohammed Arif, Phillip A. Richardson

International Journal of Aviation, Aeronautics, and Aerospace

Customer service at airports has become a key priority for airport operators given the high degree of competitions. This paper uses an airport customer service model to analyze three examples from the United Arab Emirates (UAE). Passenger interviews, statistical information, customer feedback and other forms of information have been utilized to learn more about the customer view on the quality of service offered at these three airports. Detailed qualitative analysis of these case studies has highlighted some key issues in the area of customer service and identifies some opportunities for improvement.

Modeling Queues With Simulation Versus M/M/C Models, Kum Khiong Yang, Joyce M. W. Low, Cayirli Tugba

Research Collection Lee Kong Chian School Of Business

This paper examines the performance of single-queue service systems using a combination of computer simulation and M/M/C queuing models. Our results show that the accuracy of M/M/C models is significantly affected by the assumptions supporting the models. Managers should therefore exercise caution in using the M/M/C models for designing queuing systems when the models’ assumptions are violated. Our results show that cost-centric and servicecentric firms should manage their queues differently. While cost-centric firms should target higher arrival load, single service session, and front-loaded arrival pattern for higher efficiency, service-centric firms should strive for lower arrival load, multiple short sessions and …

Robust Two-Stage Stochastic Linear Programs With Moment Constraints, Sarah Yini Gao, Lingchen Kong, Jie Sun

Research Collection Lee Kong Chian School Of Business

We consider the two-stage stochastic linear programming model, in which the recourse function is a worst case expected value over a set of probabilistic distributions. These distributions share the same first- and second-order moments. By using duality of semi-infinite programming and assuming knowledge on extreme points of the dual polyhedron of the constraints, we show that a deterministic equivalence of the two-stage problem is a second-order cone optimization problem. Numerical examples are presented to show non-conservativeness and computational advantage of this approach.

Service Systems With Finite And Heterogeneous Customer Arrivals, Rowan Wang, Oualid Jouini, Saif Benjaafar

Research Collection Lee Kong Chian School Of Business

We consider service systems with a finite number of customer arrivals, where customer interarrival times and service times are both stochastic and heterogeneous. Applications of such systems are numerous and include systems where arrivals are driven by events or service completions in serial processes as well as systems where servers are subject to learning or fatigue. Using an embedded Markov chain approach, we characterize the waiting time distribution for each customer, from which we obtain various performance measures of interest, including the expected waiting time of a specific customer, the expected waiting time of an arbitrary customer, and the expected …

The Business Of Beds: An Exploration Of Hotel And Hostel Business Strategy, Robert B. Bunda

Honors Scholar Theses

At their cores, hotels and hostels are similar in that they provide a place for travelers to stay. Despite this core similarity, the structures of the two industries are radically different. The hotel industry began in the Middle Ages and has given rise to massive multinational companies, many managing more than four thousand hotels. In stark contrast, the hostel industry began in 1909 and is mostly comprised of independently owned and operated guesthouses, with the largest global chain comprising of less than twenty properties. This study first defines the hotel and hostel industries and examines the different experiences they offer …

Detailed Inventory Record Inaccuracy Analysis, Hayrettin Kaan Okyay

Graduate Theses and Dissertations

This dissertation performs a methodical analysis to understand the behavior of inventory record inaccuracy (IRI) when it is influenced by demand, supply and lead time uncertainty in both online and offline retail environment separately. Additionally, this study identifies the susceptibility of the inventory systems towards IRI due to conventional perfect data visibility assumptions. Two different alternatives for such methods are presented and analyzed; the IRI resistance and the error control methods. The discussed methods effectively countered various aspects of IRI; the IRI resistance method performs better on stock-out and lost sales, whereas error control method keeps lower inventory. Furthermore, this …

Unintended Consequences: Lessons Learned When Starting A Logistics & Transportation Doctoral Program, Stephen M. Rutner, C. David Shephard, Paige S. Rutner

Journal of Transportation Management

Many universities evaluate the costs and benefits of academic programs. An important decision is whether to offer a doctoral degree. Most articles and academics focus on the numerous benefits of a doctoral program. While many of the benefits that can stem from a doctoral program are summarized in this manuscript, the primary purpose is to highlight some of the hidden costs to creating and operating a doctoral program. The authors use their experience in developing a doctoral program in Logistics and Transportation to illustrate many of these potentially hidden costs. This should provide academics and administrators with better information to …
