    Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating departments are considered. Methodology includes a firm systems operation model combined with capital budgeting and an integer programming based investment model. Results indicate the resources realize a positive return as a whole, but some enterprises are not using resources profitably. The integer investment model is found to be superior for investigating whether to continue multiple interrelated enterprises.agribusiness, enterprise selection, mathematical programming, optimal enterprise organization, Agribusiness,

    Performance Improvements through Implementation of Lean Practices: A Study of the U.K. Red Meat Industry

    Get PDF
    'Lean' is an established industrial paradigm with proven track record in various sectors of the industry (Womack & Jones, 1996). World-class Companies such as Toyota (second biggest global car manufacturer), Porsche (most profitable global OEM), Boeing (largest global aerospace business) and Tesco (third largest global retailer) have adopted Lean at the corporate level. This paper reports on the introduction of 'Lean Thinking' to a new sector - the 'Red Meat Industry' (Food Chain Centre, 2004). This contribution highlights the benefits of lean production techniques in different stages of the red meat value chain and reports 2- 3% potential cost savings at each stage of the chain.Lean process, red meat industry, Takt-time, work standardization, Livestock Production/Industries,

    Design space exploration of a poultry fillet processing system using discrete-event simulation

    Get PDF
    Developments in the poultry processing industry, such as how livestock is raised and how consumers buy meat, make it increasingly difficult to design poultry processing systems that meet evolving standards. More and more iterations of (re)design are required to optimize the product flow in these systems. This paper presents a method for design space exploration of production systems using discrete-event simulation. This method automates most steps of design space exploration: iterating on the design, model construction, performing simulation experiments, and interpreting the simulation results. This greatly reduces the time and effort required to iterate through different designs. A case study is presented which shows that this method can be effective for design space exploration of poultry processing systems.Comment: FOODOPS 202

    Expanding Urban Cultural Production:: Operational Landscape of 60 Million Chickens

    Get PDF
    This research paper tackles the principle question of how operational landscapes operating at a territorial scale are impacting rural communities. The spatial design disciplines, as stewards of the built environment, need to take concerted steps to broaden their scope of design related to the franchise-driven space of corporate America. No longer can the permanence of architecture fall victim to the dynamic and flexible systems that created it. As such, this paper will present a case study focusing on Costco's forthcoming chicken plant in Fremont, Nebraska as a form of "urban” cultural production constructed to service the 60 million rotisserie chickens sold by Costco wholesale stores each year

    Traceability -- A Literature Review

    Get PDF
    In light of recent food safety crises and international trade concerns associated with food or animal associated diseases, traceability has once again become important in the minds of public policymakers, business decision makers, consumers and special interest groups. This study reviews studies on traceability, government regulation and consumer behaviour, provide case studies of current traceability systems and a rough breakdown of various costs and benefits of traceability. This report aims to identify gaps that may currently exist in the literature on traceability in the domestic beef supply chain, as well as provide possible directions for future research into said issue. Three main conclusions can be drawn from this study. First, there is a lack of a common definition of traceability. Hence identifying similarities and differences across studies becomes difficult if not impossible. To this end, this study adopts CFIA’s definition of traceability. This definition has been adopted by numerous other agencies including the EU’s official definition of traceability however it may or may not be acceptable from the perspective of major Canadian beef and cattle trade partners. Second, the studies reviewed in this report address one or more of five key objectives; the impact of changing consumer behaviour on market participants, suppliers incentive to adopt or participate in traceability, impact of regulatory changes, supplier response to crisis and technical description of traceability systems. Drawing from the insights from the consumer studies, it seems as if consumers do not value traceability per se, traceability is a means for consumers to receive validation of another production or process attribute that they are interested in. Moreover, supply chain improvement, food safety control and accessing foreign market segments are strong incentives for primary producers and processors to participate in programs with traceability features. However the objectives addressed by the studies reviewed in this paper are not necessarily the objectives that are of most immediate relevance to decision makers about appropriate traceability standards to recommend, require, subsidize etc. In many cases the research objectives of previous work have been extremely narrow creating a body of literature that is incomplete in certain key areas. Third, case studies of existing traceability systems in Australia, the UK, Scotland, Brazil and Uruguay indicate that the pattern of development varies widely across sectors and regions. In summary, a traceability system by itself cannot provide value-added for all participants in the industry; it is merely a protocol for documenting and sharing information. Value is added to participants in the marketing chain through traceability in the form of reduced transactions costs in the case of a food safety incident and through the ability to shift liability. To ensure consumer benefit and have premiums returned to primary producers the type of information that consumers value is an important issue for future research. A successful program that peaks consumer interest and can enhance their eating experience can generate economic benefits to all sectors in the beef industry. International market access will increasingly require traceability in the marketing system in order to satisfy trade restrictions in the case of animal diseases and country of origin labelling, to name only a few examples. Designing appropriate traceability protocols industry wide is therefore becoming very important.traceability, institutions, Canada, consumer behaviour, producer behaviour, supply chain, Agricultural and Food Policy, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Health Economics and Policy, International Relations/Trade, Livestock Production/Industries, Marketing, Production Economics, D020, D100, D200, Q100,

    Agribusiness supply chain risk management: A review of quantitative decision models

    Get PDF
    Supply chain risk management is a large and growing field of research. However, within this field, mathematical models for agricultural products have received relatively little attention. This is somewhat surprising as risk management is even more important for agricultural supply chains due to challenges associated with seasonality, supply spikes, long supply lead-times, and perishability. This paper carries out a thorough review of the relatively limited literature on quantitative risk management models for agricultural supply chains. Specifically, we identify robustness and resilience as two key techniques for managing risk. Since these terms are not used consistently in the literature, we propose clear definitions and metrics for these terms; we then use these definitions to classify the agricultural supply chain risk management literature. Implications are given for both practice and future research on agricultural supply chain risk management

    The Beef Delivery System: Optimal Plant Sizes, Locations and Product Flows

    Get PDF
    The United States beef delivery system is composed of three stages: procurement, processing, and distribution. Minimization of costs associated with these stages can be accomplished best by identification of optimal plant sizes and locations. Research was directed toward an analytical approach that could be used to minimize total costs of the U.S. beef delivery system. This report will discuss the grid system used to divide the · United States into study units, describe features of the model used, discuss research results, and offer conclusions
