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 …


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 …


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 …

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 …

Designing a manufacturing network entails devising and managing flows of innovation and know-how—not just determining what to produce and where—and organizing the resulting logistics flows.


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 ± …

The Stall-Design Paradox: Neck Rails Increase Lameness But Improve Udder And Stall Hygiene, F. Bernardi, J. A. Fregonesi, C. Winckler, D. M. Veira, M. A. G. Von Keyserlingk, D. M. Weary Jul 2009

The Stall-Design Paradox: Neck Rails Increase Lameness But Improve Udder And Stall Hygiene, F. Bernardi, J. A. Fregonesi, C. Winckler, D. M. Veira, M. A. G. Von Keyserlingk, D. M. Weary

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 …

Cow Comfort In Tie-Stalls: Increased Depth Of Shavings Or Straw Bedding Increases Lying Time, C. B. Tucker, D. M. Weary, M. A. G. Von Keyserlingk, K. A. Beauchemin

Housing and Confinement of Farm Animals Collection

Over half of US dairy operations use tie-stalls, but these farming systems have received relatively little research attention in terms of stall design and management. The current study tested the effects of the amount of 2 bedding materials, straw and shavings, on dairy cattle lying behavior. The effects of 4 levels of shavings, 3, 9, 15, and 24 kg/stall (experiment 1, n = 12), and high and low levels of straw in 2 separate experiments: 1, 3, 5, and 7 kg/stall (experiment 2, n = 12) and 0.5, 1, 2, and 3 kg/stall (experiment 3, n = 12) were …


A Case Of Voip Implementation Using Open Source, Russell J. Roysden Jun 2009

A Case Of Voip Implementation Using Open Source, Russell J. Roysden

Management Information Systems Faculty Publications

Voice over Internet Protocol (VoIP) has progressed from a limited, untested technology to a feature-rich service that continues to find a place in all types of businesses. Companies such as Vonage and Skype have built successful business models based on VoIP services, and major telecommunications companies such as AT&T and Time Warner have followed suit with bundled offerings of phone, cable, and Internet services. Research has suggested that the Small-to-Medium Business (SMB) marketplace is quickly moving towards VoIP for productivity and efficiency benefits, convenience, and cost savings (Frost & Sullivan Company, 2006).


Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim Jun 2009

Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

A natural extension of the bucket brigade model of manufacturing is capable of chaotic behavior in which the product intercompletion times are, in effect, random, even though the model is completely deterministic. This is, we believe, the first proven instance of chaos in discrete manufacturing. Chaotic behavior represents a new challenge to the traditional tools of engineering management to reduce variability in production lines. Fortunately, if configured correctly, a bucket brigade assembly line can avoid such pathologies.


Information Sharing And Strategic Signaling In Supply Chains, Robert J. Kauffman, Hamid Mohtadi Jun 2009

Information Sharing And Strategic Signaling In Supply Chains, Robert J. Kauffman, Hamid Mohtadi

Research Collection School Of Computing and Information Systems

Information sharing in procurement occurs in rich and varied industry contexts in which managerial decisions are made and organizational strategy is formulated. We explore how information sharing ought to work in procurement contexts that involve investments in inter-organizational information systems (IOS) and collaborative planning, forecasting and replenishment (CPFR) practices. How and under what circumstances does a firm that plays the role of a supply chain buyer decide to share information on key variables, such as point-of-sale consumer demand data with its supplier, up the supply chain? This is a key issue that crosses the boundary between supply chain management and …


Modelling Reconfigurable Manufacturing Systems With Coloured Timed Petri Nets, Lianfeng Zhang, Brian Rodrigues Jun 2009

Modelling Reconfigurable Manufacturing Systems With Coloured Timed Petri Nets, Lianfeng Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Reconfigurable manufacturing systems (RMSs) have been acknowledged as a promising means of providing manufacturing companies with the required production capacities and capabilities. This is accomplished through reconfiguring system elements over time for a diverse set of individualised products often required in small quantities and with short delivery lead times. Recognising the importance of dynamic modelling and visualisation in decision-making support in RMSs and the limitations of current research, we propose in this paper to model RMSs with Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In view of the …
