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

ISSCM 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).

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. …

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 …

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 …

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.

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 …

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 …

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

ISSCM 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.

Information Sharing With Suppliers To Improve Mass Customization Capability: A Trust Perspective, Kun Liao, Zhongming Ma, Cen-Tsong Lin

All Faculty Scholarship for the College of Business

Trust is essential for business relationships within a supply chain. On the basis of over 200 responses from suppliers in the U.S. and China, this study empirically tests the relationship between trust and manufacturer-supplier information sharing. High trust can lead to frequent information sharing between suppliers and manufacturers. Frequent information sharing causes high mass customization capabilities. The moderating effect of country culture is also found for the relationship between trust and financial information sharing.

Trust-Driven Joint Operations Practices To Achieve Mass Customization: A Comparative Study For U.S., Chinese And Japanese Companies, Kun Liao, Thomas W. Sharkey, Mark A. Vonderembse, T. S. Ragu-Nathan

All Faculty Scholarship for the College of Business

This study builds a model of trust, based on joint operational activities and mass customization using theories of social capital and the resource-based view of the firm. Based on 208 responses from suppliers in the U.S. and China, this study empirically supports the notion that trust positively drives manufacturer-supplier activities in operations. It also supports the claim that joint operations activities contribute to mass customization capabilities in a significant way. Moreover, the level of trust and the degree of joint activities are different for the four types of suppliers used in the study: U.S. brands produced in North America, Japanese …

Choosing And Using A Co-Packer, Pamela L. Brady, Steve Seideman, Justin R. Morris

Research Reports and Research Bulletins

Co-packing, also known as contract packaging, is when a company contracts with another company to manufacture and package foods that the original company will sell. Products on the market that have been co-packed range from nationally known brands to those sold under private labels. The use of co-packers has become extremely popular with entrepreneurs who have a product idea but lack the $100,000 or more needed to set up a manufacturing facility to produce the product. In addition, many entrepreneurs starting a foods business find that, in today’s market conditions, greater profits are achieved through sales and marketing innovations than …

Relationship Between Pre-Slaughter Stress Responsiveness And Beef Quality In Three Cattle Breeds, V. Muchenje, K. Dzama, M. Chimonyo, P. E. Strydom, J. G. Raats

Slaughter and Slaughtering Practices Collection

The relationship between stress responsiveness and beef quality of 40 Nguni, 30 Bonsmara and 30 Angus steers was determined. The L* values, pHu, cooking loss (CL) and Warner-Bratzler shear force (WBSF) were determined. Catecholamine levels were determined from urine samples collected at slaughter. Bonsmara steers had the highest (P < 0.05) levels of catecholamines with respective epinephrine, norepinephrine and dopamine concentrations of 10.8, 9.7 and 14.8 nmol/mmol. Nguni steers had the lowest (P < 0.05) levels of catecholamines, with respective catecholamine concentrations of 5.1, 4.3 and 4.0 nmol/mmol. In the Nguni steers, there were significant (P < 0.05) correlations between catecholamines and L* and between dopamine and tenderness in meat aged for two days (WBSF2). In the Bonsmara, dopamine was correlated (P < 0.05) pHu, WBSF2 and CL. No significant correlations were found in the Angus. Therefore the relationship between stress responsiveness and certain beef quality traits may not be similar in different breeds.

Welfare Issues With Conventional Manual Catching Of Broiler Chickens And Turkeys

Agribusiness Reports

Approximately 9 billion chickens and 270 million turkeys are raised for meat annually in the United States. When these farmed birds reach market weight, they must be caught and crated for transport from production facilities to slaughter plants. Conventional manual catching results in severely compromised welfare. Birds experience stress and fear, and can be physically harmed, suffering bruises, broken bones, dislocated joints, and other injuries. Alternatives to conventional manual catching practices that improve bird welfare exist, including mechanical harvesters, gentle manual catching, and, for turkeys, herding into specially designed transport crates.

The Impact Of Industrialized Animal Agriculture On World Hunger

Agribusiness Reports

Of the world’s nearly 6.8 billion humans, almost 1 billion people are malnourished. Feeding half the world’s grain crop to animals raised for meat, eggs, and milk instead of directly to humans is a significant waste of natural resources, including fossil fuels, water, and land. Raising animals for food is also a major contributor to global warming, which is expected to further worsen food security globally. To meet the daily nutritional needs of a rapidly expanding population, the world’s human community, particularly in Western countries, must reduce its reliance on animal products and shift to a more plant-based diet.

The Implications Of Farm Animal-Based Bioenergy Production

Agribusiness Reports

As the current and potential impacts of climate change become more evident and increasingly urgent, entities such as governments, corporations, and non-governmental organizations (NGOs) are seeking out non-fossil fuelbased sources of energy to mitigate those effects. In addition, many governments are investigating ways to promote their own domestic energy sources as a result of rising oil prices. Bioenergy—made from recently living organic matter, such as plants, agricultural waste and crop residue, meat processing wastes, or farmed animals’ fats and manure—has quickly become one of the fastest growing, and controversial, alternative energy sources. Globally, production of biofuels, generally used for transport, …

Commonalities And Differences Between Service And Manufacturing Supply Chains: Combining Operations Management Studies With Supply Chain Management, Ming Zhou, Taeho Park, John Yi

Faculty Publications, School of Management

The service sector of the US economy has been gaining importance. As the service sector evolves, the study of service supply chain starts to gain attention. In this study, we conduct an exploratory review on the studies of manufacturing and service supply chains. We focus on the studies that explore the differences and commonalities between manufacturing and service supply chains. We combine operations management literature with supply chain studies in order to provide an interdisciplinary framework that brings up both the operational and strategic views on the management commonalities and differences between the two types of supply chains.

Diffusion Of Complex Information Systems Across Organizations, Anand Jeyaraj

ISSCM Faculty Publications

Organizations deal with complex information systems innovations such as enterprise resource planning systems to enable and support their operations. While there is considerable research on organizations’ adoption, implementation, and use of such complex information systems, prior literature has not dwelt as much on the diffusion or the spread of such complex information systems across a population of organizations. A limited number of studies have shown different information sources such as external, internal, and mixed influences to drive diffusion, and found variations in the diffusion patterns of different complex information systems. These findings, however, belong to different populations and do not …

Supply Chain Management Practices As A Mediator Of The Relationship Between Operations Capability And Firm Performance, Chinchun Hsu, Keah Choon Tan, Vijay R. Kannan, G. Keong Leong

Management Faculty Publications

The current study uses mediated regression analysis and structural equation modeling to test the proposition that supply chain management practices mediate the relationship between operations capability and firm performance. Operations capability is defined in terms of a firm's new product design and development, total quality management and just-in-time capabilities. Results support the research model and also suggest the existence of a direct relationship between operations capability and performance.
