Managing Supply Uncertainty With An Information Market, Zhiling Guo, Fang Fang, Andrew B. Whinston Dec 2009

Managing Supply Uncertainty With An Information Market, Zhiling Guo, Fang Fang, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

We propose a market-based information aggregation mechanism to manage the supply side uncertainty in the supply chain. In our analytical model, a simple supply chain consists of a group of retailers who order a homogeneous product from two suppliers. The two suppliers differ in their ability to fulfill orders – one always delivers orders and the other fulfills orders probabilistically. We model the supply chain decisions as a Stackelberg game where the supplier who has uncertain reliability decides a wholesale price before the retailers who independently receive signals about the supplier’s reliability determine their sourcing strategies. We then propose an …


Cow Preference And Usage Of Free Stalls Compared With An Open Pack Area, J. A. Fregonesi, M. A. G. Von Keyserlingk, D. M. Weary Nov 2009

Cow Preference And Usage Of Free Stalls Compared With An Open Pack Area, J. A. Fregonesi, M. A. G. Von Keyserlingk, D. M. Weary

Housing and Confinement of Farm Animals Collection

Free-stall housing systems are designed to provide a comfortable and hygienic lying area, but some aspects of stall design may restrict usage by cows. The aim of this study was to compare free-stall housing with a comparable lying area (open pack) without stall partitions. We predicted that cows would spend more time lying down and standing in the bedded area when provided access to an open pack than when in free stalls. We also predicted that cows would spend less time standing outside of the lying area and less time perching with the front 2 hooves in the lying area …


Prevalence And Risk Factors For Skin Lesions On Legs Of Dairy Cattle Housed In Freestalls In Norway, C. Kielland, L. E. Ruud, A. J. Zanella, O. Østerås Nov 2009

Prevalence And Risk Factors For Skin Lesions On Legs Of Dairy Cattle Housed In Freestalls In Norway, C. Kielland, L. E. Ruud, A. J. Zanella, O. Østerås

Housing and Confinement of Farm Animals Collection

Appropriate indoor housing facilities for dairy cattle promote improved animal welfare. Skin alterations are an indicator of dysfunctional housing. The purpose was to determine the relationship between different housing design and skin lesions, hence providing farmers more insight into how to reduce the occurrence of lesions. A cross-sectional study was conducted on 2,335 animals in 232 Norwegian freestall-housed dairy cattle from September 2006 to June 2007. A model was established to investigate risk factors related to the presence of lesions including hair loss, swelling, and wounds on the legs of dairy cattle. Separate models were developed to investigate risk factors …

Private Warehouse Investment Strategies In Small Versus Large Manufacturing Firms, John E. Spillan, Michael A. Mcginnis, Jonathan W. Kohn Oct 2009

Private Warehouse Investment Strategies In Small Versus Large Manufacturing Firms, John E. Spillan, Michael A. Mcginnis, Jonathan W. Kohn

Journal of Transportation Management

The research reported in this manuscript empirically compares the private warehouse investment strategies of small and large manufacturing firms. Mail surveys were administered to independent samples of small and large United States manufacturing firms. This research is based on a series of identically worded questions administered to both samples. Data was factor analyzed and cluster analyzed to identify three private warehouse investment strategies for small and large firms and two strategies for large firms. Analyses of three independent variables further evaluated differences in private warehouse investment strategies. Finally, the warehouse mix of small and of large firms was compared. This …


Roles And Capabilities Of The Retail Supply Chain Organization, C. Clifford Defee, Wesley S. Randall, Brian J. Gibson Oct 2009

Roles And Capabilities Of The Retail Supply Chain Organization, C. Clifford Defee, Wesley S. Randall, Brian J. Gibson

Journal of Transportation Management

Supply chain management (SCM) has become a critical strategic function in recent years. Research in the discipline has been focused toward the upstream side of the supply chain on functions such as warehousing, transportation, procurement and production. As power has shifted downstream toward retailers and their customers, SCM research has been slow to respond. This represents a significant gap, and a significant opportunity. Retailers face challenges that differ from those found in upstream suppliers and manufacturers. We present findings from a study of senior supply chain executives in the retail industry that focuses on the supply chain challenges of greatest …


Avoiding Shipper/Consignee Double Payment Liability, Roger F. Huff Oct 2009

Avoiding Shipper/Consignee Double Payment Liability, Roger F. Huff

Journal of Transportation Management

The purpose of this article is neither to engage in an overly technical legal analysis nor to disparage motor carriers who bring “double liability” claims against financially viable shippers/consignees; after all the trucking company has performed a valuable service and is simply trying to be paid “once” for that service - even though the financially viable shipper or consignee may have to pay twice with the bankrupt/insolvent third party absconding. The purpose of this article is generally to provide some “front-end” practical suggestions to shippers/ consignees in how to avoid being in court on one of these claims in the …


The Impact Of Hours-Of-Service Regulations On Transportation Productivity And Safety: A Summary Of Findings From The Literature, Hokey Min Oct 2009

The Impact Of Hours-Of-Service Regulations On Transportation Productivity And Safety: A Summary Of Findings From The Literature, Hokey Min

Journal of Transportation Management

Since driver fatigue has known to be the primary cause of serious truck crashes, the Federal Motor Carrier Safety Administration (FMCSA) has attempted to implement new hours-of-service (HOS) regulations that aimed to promote safer driving environments. The new HOS regulations effective on October T‘ of2005, however, may lead to substantial cost increases for the trucking industry which will in turn hurt shippers and ultimately customers. For instance, motor carriers may need to hire additional drivers to comply with new HOS regulations requiring that drivers be placed out of service until they accumulated enough off-duty time. In particular, off-duty breaks required …


A Longitudial Study Of Private Warehouse Investment Strategies, Jonathan W. Kohn, Michael A. Mcginnis, John E. Spillan Oct 2009

A Longitudial Study Of Private Warehouse Investment Strategies, Jonathan W. Kohn, Michael A. Mcginnis, John E. Spillan

Journal of Transportation Management

This article revisits private warehouse investment decision making, a topic previously examined in 1989 by McGinnis, Kohn, and Myers (1990). Since then there has been a substantial amount of discussion regarding the scope and nature of logistics /supply chain management. In particular the roles of private, contract, and public warehousing has been discussed, increased emphasis on financial performance and strategic decision making may have altered the criteria for investment decisions in private warehousing, increased coordination of supply chains may have altered the relative importance of private, contract, and private warehousing, and increasing emphasis on controlling inventory investment may have shifted …


A Triadic View Of Truck Driver Satisfaction, Stephen A. Lemay, Zachary Williams, Michael Carver Oct 2009

A Triadic View Of Truck Driver Satisfaction, Stephen A. Lemay, Zachary Williams, Michael Carver

Journal of Transportation Management

In this research, the authors surveyed three groups concerning job satisfaction: experienced drivers, new drivers, and managers. Statistical tests were conducted using a sample of 196 new drivers, 145 experienced drivers, and 59 managers from a large TL firm based in the U.S. The results suggest that many discrepancies exist on driver satisfaction among the three perspectives. In particular, new drivers provide managers with opportunities and challenges for satisfaction. Given the current state of the trucking industry, managers will likely benefit from approaching this segment of drivers differently to meet their expectations and keep them from leaving their firms.

Lying Behavior: Assessing Within- And Betweenherd Variation In Free-Stall-Housed Dairy Cows, K. Ito, D. M. Weary, M. A. G. Von Keyserlingk Sep 2009

Lying Behavior: Assessing Within- And Betweenherd Variation In Free-Stall-Housed Dairy Cows, K. Ito, D. M. Weary, M. A. G. Von Keyserlingk

Housing and Confinement of Farm Animals Collection

One of the most important design criteria for dairy cow housing is access to a comfortable lying area. Behaviors such as the time cows spend lying down and how often they lie down can be used to evaluate the quality of stalls; however, assessing lying behavior on farms can be challenging. Indices such as the cow comfort index (CCI) and stall use index (SUI) have been widely used in on-farm assessments. The aims were to establish reliable sampling and recording methods for measuring lying behavior, to evaluate the adequacy of the CCI and SUI as estimates of lying behavior, and …

Preference And Usage Of Pasture Versus Free-Stall Housing By Lactating Dairy Cattle, A. L. Legrand, M. A. G. Von Keyserlingk, D. M. Weary Aug 2009

Preference And Usage Of Pasture Versus Free-Stall Housing By Lactating Dairy Cattle, A. L. Legrand, M. A. G. Von Keyserlingk, D. M. Weary

Housing and Confinement of Farm Animals Collection

The aim of the current study was to assess if cows preferred pasture or indoor housing, and how diurnal and environmental factors affected this preference. Lactating dairy cows (n = 5 groups, each containing 5 cows) were sequentially housed either in a free-stall barn on pasture, or given the choice between the 2 environments. Each group was tested 3 times under each condition, for a total of 21 d, to assess the effects of varying climatic conditions (outdoor temperature ranged from 9.9 to 28.2°C and daily rainfall from 0 to 65 mm/d over the course of the experiment). When provided …


Preference For Pasture Versus Freestall Housing By Dairy Cattle When Stall Availability Indoors Is Reduced, A. C. Falk, D. M. Weary, C. Winckler, M. A. G. Von Keyserlingk Aug 2009

Preference For Pasture Versus Freestall Housing By Dairy Cattle When Stall Availability Indoors Is Reduced, A. C. Falk, D. M. Weary, C. Winckler, M. A. G. Von Keyserlingk

Housing and Confinement of Farm Animals Collection

Providing cattle with access to pasture has been shown to yield benefits, including access to more space, fewer agonistic interactions, better air quality, and the ability to perform a greater range of normal behaviors. Preference for pasture appears to depend on several parameters, including weather conditions and availability of shade. The primary aim of this study was to evaluate the preference for pasture versus inside a freestall barn with variable stocking densities at the stalls. We also investigated the effect of temperature-humidity index (THI) and precipitation on this preference. Overall, cows spent on average 13.7 ± 2.6 h/d (mean ± …

Housing and Confinement of Farm Animals Collection

Housing conditions for dairy cows are thought to af-fect lameness, but almost no experimental work has addressed this link. The aim was to assess the effect of one feature of free-stall design, the position of the neck rail, testing the prediction that cows will be more likely to become lame if using pens with the neck rail positioned such that it prevents standing fully inside the stall. Cows (n = 32) were housed in 8 pens. Treat-ments were tested using a crossover design; treatments were allocated alternately to pens at the beginning of the experiment and switched halfway through the …
