The Sourcing Hub And Upstream Supplier Networks, Anupam Agrawal, Luk N. Van Wassenhove, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

In this paper, we explore how firms can better manage their sourcing by developing relationships not only with their suppliers but also with their suppliers' suppliers. We detail an empirical case study explaining how the firm developed relationships with its suppliers and raw material suppliers via a collaborative center, the sourcing hub. We then analytically model the scenarios encountered in our empirical work and examine two facets of upstream sourcing under uncertain demand scenarios: (a) firms can supply raw material directly to their suppliers, and this may be beneficial for the firm and its suppliers; and (b) firms can bring …

Joint Product Improvement By Client And Customer Support Center: The Role Of Gain-Share Contracts In Coordination, Shantanu Bhattacharya, Alok Gupta, Sameer Hasija

Research Collection Lee Kong Chian School Of Business

We study the role of different contract types in coordinating the joint product improvement effort of a client and a customer support center. The customer support center's costly efforts at joint product improvement include transcribing and analyzing customer feedback, analyzing market trends, and investing in product design. Yet this cooperative role must be adequately incentivized by the client, since it could lead to fewer service requests and hence lower revenues for the customer support center. We model this problem as a sequential game with double-sided moral hazard in a principal-agent framework (in which the client is the principal). We follow …

Distributionally Robust Mixed Integer Linear Programs: Persistency Models With Applications, Xiaobo Li, Karthik Natarajan, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

In this paper, we review recent advances in the distributional analysis of mixed integer linear programs with random objective coefficients. Suppose that the probability distribution of the objective coefficients is incompletely specified and characterized through partial moment information. Conic programming methods have been recently used to find distributionally robust bounds for the expected optimal value of mixed integer linear programs over the set of all distributions with the given moment information. These methods also provide additional information on the probability that a binary variable attains a value of 1 in the optimal solution for 0–1 integer linear programs. This probability …

Heat Stress: A Major Contributor To Poor Animal Welfare Associated With Long-Haul Live Export Voyages, Malcolm P. Caulfield, Heather Cambridge, Susan F. Foster, Paul D. Mcgreevy

Transport of Farm Animals Collection

Recent investigations by the Australian Department of Agriculture, Fisheries and Forestry into high mortalities on live export voyages from Australia to the Middle East during the Northern hemisphere summer suggest that animal welfare may be compromised by heat stress. The live export industry has generated a computer model that aims to assess the risk of heat stress and to contain mortality levels on live export ships below certain arbitrary limits. Although the model must be complied with under Australian law, it is not currently available for independent scientific scrutiny, and there is concern that model and the mandated space allowances …

Comparison As Incentive: Newsvendor Decisions In A Social Context, Buket Avci, Zeina Loutfi, Jurgen Mihm, Elena Belavina, Steffen Keck

Research Collection Lee Kong Chian School Of Business

Explicit formal mechanisms dominate the discussion about incentives in Operations Management, yet many other mechanisms exist. Social comparison between peers may provide strong implicit incentives for individuals. Social comparison arises naturally in all social settings and may thus be unintended; however, many companies deliberately use it to motivate employees. In this study, we model a social context in which purchasers evaluate their performance relative to their peers; a feeling of inferiority results in a negative contribution to utility, whereas a feeling of superiority results in a positive contribution. We find that social comparison induces characteristic deviations from the newsvendor optimum …

New Bounds For The Price Of Anarchy Under Nonlinear And Asymmetric Cost, Deren Han, Jie Sun, Marcus Ang

Research Collection Lee Kong Chian School Of Business

We derive new bounds for the price of anarchy under nonlinear and asymmetric costs. The bounds depend on an additional factor called the intrinsic cost of the system and therefore tend to be more accurate than the current bounds that are dependent only on the degree of asymmetry of the Jacobian and the degree of the nonlinearity of the cost function.

Refining Shippers’ Dyadic Cost, Risk, And Delivery Responsibilities: The Principal Changes To Incoterms And A Transaction Cost Focus For The Future, Drew M. Stapleton, Vivek Pande, Soumen Ghosh, Uzay Damali

Journal of Transportation Management

We first explore the changes in the latest version of Incoterms and explain why and how they have been refined to better capture contemporary global and domestic shipping practices and policies. Next we graphically explain each of the eleven INCOTERMS 2010 and specify exact delivery points, those critical points at which cost and risk responsibilities shift from the Seller to the Buyer. We then provide a discussion to better explain the application of the terms from a practitioner’s view and note that many shippers and freight forwarders still revert to long practiced shipping policies, leaving themselves vulnerable. We close by …

Moving Beyond Boycotts: Strategies For Shared Responsibility In The Collegiate Apparel Industry, Scott Kelley

Mission and Ministry Publications

the factory collapse at Rana Plaza in Bangladesh is a painful reminder that labor issues in the apparel industry are abundant and troubling. Catholic Colleges and Universities (CCUs) are confronted with the reality that many apparel manufacturers can operate in stark contrast to the vision of economic justice found in Catholic social thought (CST). In response, activists on CCU campuses have demanded that CCUs boycott apparel manufacturers that they believe to be in violation of their school’s values. While activism can draw much needed attention to problems in the industry, it can be a problematic response. While CST offers principles …

Organizational Identification And Supply Chain Orientation: Examining A Supply Chain Integration Paradox, Jessica L. Robinson

College of Graduate Studies: Theses & Dissertations

The current approach to operationalizing supply chain management relies on the premise that there are stages in which an organization extends internal integration to external integration by means of implementing integrative mechanisms. Although important developments have been made in identifying the common antecedents and practices for achieving internal integration and external integration, complex relational behaviors as well as integration barriers that occur within an organization, and their solutions, are the next phase to understand and integrate supply chains. Accordingly, given the internal-to-external implementation approach to supply chain integration, this dissertation examines the Social Identity construct, organizational identification, as a source …

Consumers' Perceptions Towards Sustainability: A Cross-Cultural Analysis, Mertcan Tascioglu

College of Graduate Studies: Theses & Dissertations

Sustainability has become a subject of increasing concern to academics and practitioners in recent years. Increasing consumer demand for socially responsible products encouraged supply chains to put increasing emphasis on sustainability. In adapting sustainability practices consumers play a very important role for supply chains. Thus this dissertation examines consumers’ perceptions towards sustainability practices. Although most previous research has examined environmental sustainability practices, the social dimension of sustainability has received little attention. This dissertation attempts to explore both environmental and social sustainability and their effects on consumer perceptions in different cultural contexts and price levels. Two scenario based experiments are utilized. …

Positioning Automated Guided Vehicles In A General Guide-Path Layout, Abraham Mendoza, Jose A. Ventura

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

The locations of dwell points for idle vehicles in an automated guided vehicle (AGV) system determine the response times for pick-up requests and thus affect the performance of automated manufacturing systems. In this study, we address the problem of optimally locating dwell points for multiple AGVs in general guide-path layouts with the objective of minimizing the maximum response time in the system. We propose a mixed integer linear programming (MILP) formulation for the problem. We also develop a generic genetic algorithm (GA) to find near optimal solutions. The MILP model and GA procedure are illustrated using a two-dimensional grid layout …

Integrating Analysis Into A Warehouse Design Workflow, Leon Mcginnis, Timothy Sprock

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

Supply chain analyses, including those related to material handling systems, are typically purpose-built to answer specific questions and therefore have many different implementations depending on the question, the instance data, and the solver. The purpose-built nature of these models makes it difficult to integrate them into an iterative design workflow. Despite the myriad analysis implementations, the fundamental structure of these systems and their problem domain remains unchanged, suggesting that perhaps analyses could be automatically generated on demand, given an appropriate specification of the particular system to be analyzed. We apply model-based systems engineering (MBSE) methodologies to explore this possibility in …

Throughput Analysis Of S/R Shuttle Systems, Georg Kartnig, Jörg Oser

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

Shuttle systems are used in high performance automated storage/retrieval unit load systems. Each storage level is serviced by one transfer car travelling in dual command operation. One buffer slot is located at both ends of each level. This decouples horizontal travel from vertical input/output moves, which in this case requires two independent vertical reciprocating lifts at each end of the aisle. Other systems work with only one lift used in lower throughput applications. The content of this paper is treated in the following sections starting with a problem definition and a literature survey. This is followed by a detailed functional …

Clickstream Big Data And “Delivery Before Order Making” Mode For Online Retailers, Yeming Yale Gong, Haoxuan Xu

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

Our research is inspired by a leading online retailer using clickstream big data to estimate customer demand and then ship items to customers or hubs near customers by a mode of “delivery before order making” (DBOM) mode. Using clickstream data to obtain advance demand information in order quantities, we integrate the forecasting with a singleitem uncapacitated dynamic lot sizing problem in a rolling-horizon environment. Using the simulated clickstream data, we evaluate the performance of DBOM mode.

Detailed descriptions are provided for three typical cross-dock settings by means of case illustrations. The purpose of these descriptions is to inspire break-through innovations in future cross-docking research by identifying constraints, decision problems, and performance indicators that are thoroughly anchored in current practice.

Comparison Of Alternative Configurations For Dense Warehousing Systems, Kevin R. Gue, G. Don Taylor

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

In heavily constrained environments requiring very high density storage, traditional aisle-based warehousing may not provide viable options. One feasible manifestation of high density storage systems is the ‘puzzle-based’ system, in which unit loads are moved through the system via manipulation of empty (escort) locations to retrieve desired items. Another option would be the use of movable concentric rings, with escorts being utilized to enable lateral movements of unit loads between the rings. In this paper, the authors present analytical results to compare retrieval time performance for these two types of high density storage systems for randomly demanded items under various …

Analysis Of Class-Based Storage Strategies For The Mobile Shelf-Based Order Pick System, Shobhit Nigam, Debjit Roy, Rene De Koster, Ivo J.B.F. Adan

13th IMHRC Proceedings (Cincinnati, Ohio. USA – 2014)

Mobile Shelf-based Order Pick (MSOP) systems are gaining significant in- terest for e-commerce fulfillment due to their rapid deployment capability and dynamic organization of storage pods based on item demand profiles. In this research, we model the MSOP system with class-based storage strategies and alternate pod storage policies using multi-class closed queuing networks. We observe that though closest-open location pod storage policy do not allow to efficiently use the storage spaces in comparison to random location pod storage policy in an aisle, it increases the system throughput for all item classes.
