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 …

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

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

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.

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 …

Towards A Single European Sky, Yael Gruksha-Cockayne, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

We describe an integrated decision-making framework and model that we developed to aid EUROCONTROL, the European air traffic management organization, in its vital role of constructing a single unified European sky. Combining multicriteria decision analysis with large-scale optimization methods, such as integer programming and column generation using branch and price, our model facilitates the process by which the numerous European aviation stakeholders evaluate and select technological enhancements to the European air traffic management system. We consider multiple objectives and potential disagreements by stakeholders regarding the impact of proposed system enhancements and allow for different priorities for each key performance area. …

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 …

Assessing Lameness In Cows Kept In Tie-Stalls, K. A. Leach, S. Dippel, J. Huber, S. March, C. Winckler, H. R. Whay

Housing and Confinement of Farm Animals Collection

Identifying lame cows and quantifying the prevalence of lameness are important elements of cattle welfare assessment that are generally achieved by methods involving observations of each animal walking. There is no published method for assessing lameness in cows confined in tie-stalls. The objective of this study (carried out within the European Commission’s Welfare Quality® project) was to develop a suitable method and validate it for lameness detection against a published locomotion score. A series of indicators of lameness visible in tied cows was formalized into a stall assessment protocol. This was validated against a traditional locomotion score and tested for …

Classification Of Schedule Management Barriers Through Concept Mapping, Gregory W. Voth

Theses and Dissertations

Barriers to adoption of schedule management processes are a matter of serious concern to the acquisition community. Schedule management has been widely accepted to contribute to the successful execution of complicated system development processes since the 1950s. However, studies of recent acquisition failures illustrate that over the last 15 years, there has been significant internal resistance to the adoption of schedule management processes. This exploratory effort used concept mapping to identify and classify the types of barriers existing in the Aeronautical Systems Center (ASC). A series of open-ended questions were posed to four experienced program managers in ASC. Units of …

Document Sql (Dsql) - An Accessible Yet Comprehensive Ad-Hoc Querying Frontend For Xquery, Arijit Sengupta

Management Information Systems Faculty Publications

This article presents a declarative query language, Document SQL (DSQL) that has the same look and feel as SQL and was designed by updating the semantics of SQL operations in the structured document domain. At the same time, DSQL was designed such that all queries written in it have equivalent counterparts in XQuery. Thus, by using such a language, users can take advantage of their existing SQL knowledge when writing ad-hoc queries without losing the expressive power of XQuery.

Or Practice—Efficient Short-Term Allocation And Reallocation Of Patients To Floors Of A Hospital During Demand Surges, Steven M. Thompson, Manuel Nunez, Robert Garfinkel, Matthew D. Dean

Management Faculty Publications

Many hospitals face the problem of insufficient capacity to meet demand for inpatient beds, especially during demand surges. This results in quality degradation of patient care due to large delays from admission time to the hospital until arrival at a floor. In addition, there is loss of revenue because of the inability to provide service to potential patients. A solution to the problem is to proactively transfer patients between floors in anticipation of a demand surge. Optimal reallocation poses an extraordinarily complex problem that can be modeled as a finite-horizon Markov decision process. Based on the optimization model, a decision-support …
