A Comparison Of Cross Training Policies In Different Job Shops, Kum Khiong Yang

Research Collection Lee Kong Chian School Of Business

This research compares a set of cross-training policies represented by different numbers of cross-trained workers, additional skills per cross-trained worker, and additional machines. The policies are evaluated in job shops, represented by different efficiency losses, labour utilization, variability in processing times, and worker absenteeism. Our results show that adding one machine in each department and cross-training one or two workers from each department with one additional skill is generally sufficient to realize most of the benefits of cross-training. Cross-training is thus beneficial in most job shops, unless the cost of the minimal training and spare machines is high. Our results …

Outsourcing Via Service Competition, Ehsan Elahi, Saif Benjaafar, Karen Donohue

Management Science and Information Systems Faculty Publication Series

We consider a single buyer who wishes to outsource a fixed demand for a manufactured good or service at a fixed price to a set of potential suppliers. We examine the value of competition as a mechanism for the buyer to elicit service quality from the suppliers. We compare two approaches the buyer could use to orchestrate this competition: (1) a Supplier-Allocation (SA) approach, which allocates a proportion of demand to each supplier with the proportion allocated to a supplier increasing in the quality of service the supplier promises to offer, and (2) a Supplier-Selection (SS) approach, which allocates all …

Logistics Network Design With Supplier Consolidation Hubs And Multiple Shipment Options, Michelle L. F. Cheong, Rohit Bhatnagar, Stephen C. Graves

Research Collection School Of Computing and Information Systems

An important service provided by third-party logistics (3PL) firms is to manage the inbound logistics of raw materials and components from multiple suppliers to several manufacturing plants. A key challenge for these 3PL firms is to determine how to coordinate and consolidate the transportation flow, so as to get the best overall logistics performance. One tactic is to establish consolidation hubs that collect shipments from several suppliers, consolidate these shipments, and direct the consolidated shipments to the appropriate manufacturing plant. We consider the network design problem to implement this tactic, namely deciding the number, location and operation of consolidation hubs …

Virtual Transfer Pricing Mechanisms In Global Supply Chain, Kun Liao, Jie Jennifer Zhong

All Faculty Scholarship for the College of Business

Increasingly global firms establish plants across their national borders while utilizing their home country suppliers in diverse locations. In view of complex risk factors including political uncertainty, tax rate differences, exchange risks and labor condition changes, the issues of optimizing profits through their global operations have received much attention from both academic researchers and executives. Yet, little attention has been paid in regard to virtual transfer pricing in the global supply chain. In this paper, a virtual transfer pricing model is proposed by using contract bundle within a global supply chain to lower the risks and maximize the profit potentials.

Housing and Confinement of Farm Animals Collection

The objective of this field study was to compare effect of stall base on herd health, stall maintenance, bedding cost, and producer satisfaction. Ninety-one dairies visited during a 4-mo period starting October 14, 2005 included 33 rubber-filled mattress (RFM), 27 sand, and 31 waterbed (WB) dairies. In this study, percent culled was higher for RFM (P = 0.001) and sand (P = 0.06) than WB stall base dairies. Percent of cows in fourth lactation or greater was higher on WB than either RFM (P = 0.01) or sand (P = 0.02) dairies. There was no difference between base types for …

The Welfare Of Animals In The Meat, Egg, And Dairy Industries

Agribusiness Reports

Each year in the United States, approximately 11 billion animals are raised and killed for meat, eggs, and milk. These farm animals—sentient, complex, and capable of feeling pain and frustration, joy and excitement—are viewed by industrialized agriculture as commodities and suffer myriad assaults to their physical, mental, and emotional well-being, typically denied the ability to engage in their species-specific behavioral needs. Despite the routine abuses they endure, no federal law protects animals from cruelty on the farm, and the majority of states exempt customary agricultural practices—no matter how abusive—from the scope of their animal cruelty statutes. The treatment of farm …

Welfare Issues With Selective Breeding Of Egg-Laying Hens For Productivity

Agribusiness Reports

Today’s commercial laying hens have been selectively bred to produce more than 250 eggs per year. This unnaturally high level of productivity is metabolically taxing, often causing hens to suffer from “production diseases,” including osteoporosis and accompanying bone fractures, and can lead to reproductive disorders. Research suggests that the problem of osteoporosis may be worsening, possibly due to industry’s continuous push toward maximizing productivity. For decades, economic considerations have been valued and emphasized over the welfare of individual birds. An immediate change in priorities is needed to aggressively address welfare problems associated with selective breeding for egg production.

E-Grocer Strategies: A Case Study, Anand Jeyaraj, Dubravka Cecez-Kecmanovic, Ville-Pekka Mäkeläine

Management Information Systems Faculty Publications

The recent bankruptcy of the eGrocer Webvan demonstrates that online retailers face enormous risks and hence need well thought out business strategies (Porter, 2001). This paper presents a longitudinal study of the business strategies of two eGrocers that use physical stores to house their Internet-based grocery operations (clicks-and-bricks) and two online only (pure-play) eGrocers. Our study results in a number of recommendations for successful eGrocer strategy configuration. Even though we focus on eGrocer’s strategies, we suggest that the lessons learned are of interest to other retailers planning to embark on eCommerce activities.

Real-Time Supply Chain Control Via Multi-Agent Adjustable Autonomy, Hoong Chuin Lau, Lucas Agussurja, Ramesh Thangarajoo

Research Collection School Of Computing and Information Systems

Real-time supply chain management in a rapidly changing environment requires reactive and dynamic collaboration among participating entities. In this work, we model supply chain as a multi-agent system where agents are subject to an adjustable autonomy. The autonomy of an agent refers to its capability to make and influence decisions within a multi-agent system. Adjustable autonomy means changing the autonomy of the agents during runtime as a response to changes in the environment. In the context of a supply chain, different entities will have different autonomy levels and objective functions as the environment changes, and the goal is to design …

The Sox-Rfid Connection, Porcher L. Taylor Iii, Nezih Altay

School of Professional and Continuing Studies Faculty Publications

Companies expect to gain many benefits from implementing Radio Frequency Identification (RFID) technology. Perhaps the one cited most often is lower supply chain costs, which result from the improved inventory visibility that the technology affords. But there's another often overlooked advantage that supply chain managers should know about: RFlD technology can help them fulfill the requirements of the Sarbanes-Oxley Act (SOX) if implemented and integrated properly. Conversely, RFID can complicate the already complex and costly internal mandates of SOX if the implementation is not approached the right way.

The Scale Of Operation, Profitability Based Productivity And Capacity Utilization In Seaports, The Case Study Based On The Colombo Seaport In Sri Lanka, 1980-2005, Sarath W.S.B Dasanayaka

Business Review

The Sri Lanka (formerly Ceylon), an island nation, is strategically located in the South Asian main sea routes as a gateway to the Far-East, the Middle-East, Europe, Africa and Australia. This supreme strategic hub location created commendable achievements in seaports in different magnitudes over time. More specifically, after 1977 economic policy reforms, the Colombo seaport has earned the reputation as the best managed and the most efficient hub port in the South Asia and the major transshipment center in the Indian Ocean. This success further strengthened by the liberalization of shipping in 1990 which was the land mark of changing …

A Framework For Supplier Relationship Management (Srm), Sabine Moeller, Martin Fassnacht, Sonja Klose

Research Collection Lee Kong Chian School Of Business

We perceive growing expectations concerning the impact of the purchasing function and the suppliers on overall value creation of a firm. Purchasing is the gateway between the external suppliers and the internal functions creating and delivering value for customers. This shift has incredibly enhanced the importance of the supplier base. While the old arm length collaboration is perfectly suitable for some suppliers others should be treated as close partners. However, an overall framework of Supplier Relationship Management (SRM) integrating such different types of suppliers along the course of the relationship remains desirable. Our research aims to contribute by developing a …

A Typology Of Plants In Global Manufacturing Networks, Ann Vereecke, Roland Van Dierdonck, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

The purpose of this paper is to propose a new, empirically derived typology of plants in the international manufacturing network of multinational companies. This typology is based on the knowledge flows between the plants. In our research, network analysis has been used as a methodology for understanding the position of plants in international manufacturing networks. The focus has been primarily on the intangible knowledge network, and secondarily on the physical, logistic network. Our analysis leads to four types of plants with different network roles: the isolated plants, the receivers, the hosting network players, and the active network players. Our analysis …

Fisheries Research Contract Report No. 14 - Aquatic Animal Health Subprogram: Development Of A National Translocation Policy Using Abalone And Prawns As Templates For Other Aquatic Species (Frdc Project No. 2004/080) Final Report, Brian Jones, Fran Stephens

Fisheries Research Contract Reports

The use of scientifically based hazard identification, risk analysis and risk management is fundamental to managing unwanted effects. Hazards, such as quarantine incursions, will continue to occur despite the use of risk assessment methodologies but the frequency and severity of their occurrence will be reduced.

This was recognised by the Ministerial Council on Forestry, Fisheries and Aquaculture in 1999 when they published the "National policy for the translocation of live aquatic organisms".

This FRDC project provides a simple risk assessment methodology based on the Australian Standard for Risk Management (AS/NZS 4360: 2004) and one that is consistent with the Ministerial …

Modeling The Academic Publication Pipeline, Steven E. Moss, Xiaolong Zhang, Michael M. Barth

Logistics & Supply Chain Management: Faculty Presentations (1998-2020)

In recent years, many academic institutions have implemented more stringent academic qualification standards by increasing research requirements for faculty. This paper analyzes the impact of changing research requirements in terms of faculty research output. We model the academic research pipeline including review and revision processes as a queue network and study the stationary behavior of the research pipeline. Both a theoretical model of the publication process and a simulation showing numerous combinations of submission strategies and publication requirements are presented. Within this framework, research requirements can be analyzed via probability constraints on the output process, and the research effort that …

An Adaptive Tabu Search Heuristic For The Location Routing Pickup And Delivery Problem With Time Windows With A Theater Distribution Application, Robert E. Burks Jr.

Theses and Dissertations

The time constrained pickup and delivery problem (PDPTW) is a problem of finding a set of routes for a fleet of vehicles in order to satisfy a set of transportation requests. Each request represents a user-specified pickup and delivery location. The PDPTW may be used to model many problems in logistics and public transportation. The location routing problem (LRP) is an extension of the vehicle routing problem where the solution identifies the optimal location of the depots and provides the vehicle schedules and distribution routes. This dissertation seeks to blend the PDPTW and LRP areas of research and formulate a …

Suggested Research Agenda For The Railroad Industry, Barton Jennings

The railroad industry is experiencing a worldwide resurgence. International trade is booming as populations continue to grow and transportation infrastructures are nearing capacity. In the United States, the industry is being pressured to provide more services, while at the same time traffic levels are skyrocketing on a network that is much smaller than it was just fifty years ago. Additionally, security and safety issues are challenging the industry, as well as the regulatory agencies associated with railroading. To help with these problems, the industry is calling for more academic involvement through new degree programs and research initiatives. This paper reviews …

First Annual Logistics Faculty Salary Survey, M Theodore Ferris, Terrance L. Pohlen, Jerry W. Wilson

Journal of Transportation Management

While the Association to Advance Collegiate Schools of Business International (AACSB) conducts an annual survey of business school faculty and administrative salaries, the data do not include salary figures for logistics (and related areas such as transportation and supply chain management) faculty. Since the growth in number of logistics faculty positions has continued to exceed the output of doctoral programs in the field for more than a decade, it is logical to assume that logistics faculty salaries, at all levels, are increasing. However, without factual data, what salary should a new logistics Ph.D. expect, and what should an administrator budget …

In an era of budget deficits and financial cutbacks, the efficiency of state highway finances dictates future investment in road construction and maintenance. Considering the significant impact of highway infrastructure on the survival and competitiveness of the logistics industry, this paper aims to develop a meaningful set of benchmarks that will guide the state government authority in making wise investment decisions regarding road construction and maintenance. In particular, we propose a data envelopment analysis that is proven to be useful for measuring the operational efficiency of various profit or non-profit organizations. Using the examples of state highway finances for Kentucky …

Optimal Order Quantities With Remanufacturing Across New Product Generations, Shantanu Bhattacharya, V Daniel R. Guide, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

We address the problem of determining the optimal retailer order quantities from a manufacturer who makes new products in conjunction with ordering remanufactured products from a remanufacturer using used and unsold products from the previous product generation. Specifically, we determine the optimal order quantity by the retailer for four systems of decision-making: (a) the three firms make their decisions in a coordinated fashion, (b) the retailer acts independently while the manufacturer and remanufacturer coordinate their decisions, (c) the remanufacturer acts independently while the retailer and manufacturer coordinate their decisions, and (d) all three firms act independently. We model the four …

Outsourcing To Non-Identical Suppliers Via Service Competition, Ehsan Elahi, Saif Benjaafar, Karen Donohue

Management Science and Information Systems Faculty Publication Series

In this paper, we consider a single buyer who wishes to outsource a fixed demand for a manufactured good or service at a fixed price to a set of N suppliers. We examine the value of competition as a mechanism for the buyer to elicit good service quality from her suppliers. In particular, we consider a scheme in which the buyer allocates a proportion of demand to each supplier, with the proportion a supplier receives increasing in the service level she offers. Suppliers compete for expected market share, which increases in the offered service level. The suppliers affect their service …

Modeling A Reparable Supply Chain And Applying Cpfr Concepts, Sandra A. Mayhall

Theses and Dissertations

The Air Force supply chain includes parts required to build, fix, or maintain aircraft delivered to the warfighter to carry out missions. Industry has shown that following Collaborative Planning, Forecasting, and Replenishment (CPFR) concepts, particularly reducing inventory through accurate demand forecasts, has increased profits in part by lowering the holding costs of inventory and increasing sales. This is analogous to the Air Force increasing aircraft availability. There is scant evidence that demand forecasts generated at any level in the Air Force are shared with the intent of coordinating replenishment. This thesis uses a simple discrete-event stochastic simulation model to show …

Fisheries Occasional Publication No. 35 - Rock Lobster Processor Licensing Arrangements (Discussion Paper), Department Of Fisheries Western Australia

Fisheries Occasional Publications

On 28 March 2002, the Minister for Agriculture, Forestry and Fisheries, Hon Kim Chance MLC, announced the Government's position on National Competition Policy (NCP) insofar as this policy related to licensing of western rock lobster processors (hitherto referred to as 'rock lobster processors' or simply as 'processors'), as governed by the provisions of the Fish Resources Management Act 1994 (FRMA).

In making the announcement, the Minister also undertook to further "review the potential costs and risks of deregulation" ..."in 2006", when they "are better understood by both Government and industry itself'.

This document is the first stage of the review …

Plant Supply Logistics: Balancing Delivery And Stockout Costs, Jennifer A. Pope, James A. Pope

Journal of Transportation Management

A manufacturer leases rail cars to transport raw material from the supplier to the factory. The manufacturer must balance the costs of leasing rail cars versus stockouts (leading to plant closings) and inventory carrying costs. Using a model of circular queues and a simulation, the cost implications of leasing different numbers of rail cars are analyzed. It is concluded that stockout costs exceed the cost of excess inventory and capacity in the logistics system.
