Optimal deployment of wildlife law enforcement agents with analyses of agent productivity

Cowles, Cleveland J. January 1979 (has links)
A decision-aid system. for determining and achieving optimal distributions of wildlife law enforcement manpower was developed. Manpower distributions were computed by means of a workload formula for a case study application in the J.E.B. Stuart Enforcement District, Virginia Commission of Game and Inland Fisheries. A linear programming model was used to determine least cost methods of achieving prescribed manpower distributions. Simulations of permanent relocations and hiring of personnel were performed to evaluate the impact of management decisions on costs of achieving prescribed distributions. In the case study, total transfer cost resulting from simulated permanent relocation of personnel was 73% that of the present distribution, total transfer cost of simulated hiring of new personnel was 94% that of the present distribution. A simulation of inappropriate location of new personnel resulted in an increase in total transfer cost of 22% over that of the present distribution. These findings were relevant only to the case study; however, the use of the system as a general purpose simulator was demonstrated. Studies were performed of the relationships of patrol area environmental attributes, agent personal background characteristics, enforcement methods, enforcement effort, and season with enforcement efficiency (quality arrest score per enforcement hour). A wildlife law violation seriousness scale was developed in order to compute the measure of enforcement efficiency. Observations were obtained from Virginia wildlife law enforcement agents during November 1977, February, May, and August 1978. Patrol area intensity of 20 environmental variables, 25 personal background variables, 5 enforcement methods variables, total enforcement hours, and 4 study periods were independent variables. Two and 3-way interactions were detected by automatic interaction detection (AID) among total quality arrest score (QAS) by patrol, total QAS by response to citizen notification, and total enforcement hours. Analysis of covariance by multiple regression procedures indicated that methods of enforcement, effort, and their interactions we.re more closely associated with enforcement efficiency than other major categories of independent variables. Total QAS by patrol, total QAS by investigation, an interaction of total QAS by patrol and total enforcement hours, total QAS by response to citizen notification, total QAS by stakeout, and effort showed the greatest association with the dependent variable. To a lesser degree, agent rank, months of service, and whether the agent had been fired from previous employment were also shown to be associated with enforcement efficiency. Only one environmental attribute, the intensity of water recreation in the patrol area, was associated with enforcement efficiency. These results generally supported assumptions employed in the decision-aid system. / Ph. D.

Overlaying the just-in-time with Kanban system on an American production environment

Philipoom, Patrick Robert January 1986 (has links)
During the past several years, the publicized successes of Japanese production management techniques have created an interest in the potential of these techniques for application in an American manufacturing environment. One such Japanese technique that has been the focus of much attention from American manufacturers and production managers is the "just-in-time (JIT)" technique implemented with "Kanbans.”¹ However, the applications of the JIT technique in Japan that have been reported have been for large scale assembly line operations that, in general, encompass the unique physical and philosophical characteristics typical of Japanese production systems. The factors that contribute to the success of the JIT system in Japan are frequently not exhibited in manufacturing systems in the United States, especially in American systems that combine assembly and shop-type operations and encompass a high degree of system variability. As such, it is questionable whether the JIT technique can be successfully adapted to American manufacturing systems~that do not display the characteristics of Japanese production operations. Nevertheless, a number of American manufacturing companies, in hope of achieving at least some of the Japanese success in inventory control, quality control and production scheduling, have begun implementing the JIT technique in their own unique production environment. The purpose of this dissertation is to investigate implementing JIT in a non-Japanese production environment and to show how JIT can be adapted so that it can have a broader range of applicability, especially under the particular set of conditions that are very likely to exist in many American production environments. ¹Toyota uses a system of cards, called Kanbans, to control inventory and schedule production in their automotive assembly plants. / Ph.

The nature and effectiveness of management control in small family businesses/

Riordan, Diane A. January 1988 (has links)
The link between the setting of goals and the controls necessary to accomplish those goals is especially interesting in the area of small family businesses where multiple, conflicting goals are believed to interfere with business control. The actual nature of goal·setting and control in the small family firm are matters for debate because the area is not well researched. This study is an interdisciplinary effort, drawing upon existing work in accounting and business management, as well as kinship relations and group process (social psychology). It views the small family business owner-manager as a resource allocator who makes decisions within the field of family and business. Because field theory was developed to explain an individual's behavior in the context of surrounding groups, it is an especially appropriate research tool for investigating the behavior of the owner-manager in the small family business. Existing theories, specifically systems and contingency theories, are analyzed for possible strengths and weaknesses as theoretical frameworks for studying the problems that small family business owners encounter. Systems theory may be unsatisfactory as a research tool because it assumes that the business and family structures are separate and a control system can be fabricated in which the owner-manager will become a passive participant. This separation may be artificial for some small family business owners who feel a sense of responsibility to their families or to families that. assist the business. Contingency theory may be unsatisfactory as a research tool because it merely explains the obvious: The outcomes of the business are dependent upon activities related to family processes. The data were gathered by surveying approximately 900 members of the Blacksburg, Christiansburg, Radford, and Roanoke, Virginia, Chambers of Commerce. The evidence suggests that for a majority of firms field- theory is the appropriate orientation because resources are flowing in noneconomic exchanges between the businesses and families that operate them. / Ph.

The Relationship between Just-in-Time Purchasing and Total Quality Management and Their Effects on the Performance of Firms Operating in the U.S.: an Empirical Investigation

Kaynak, Hale, 1956- 08 1900 (has links)
U.S. companies have implemented just-in-time purchasing (JITP) and total quality management (TQM) techniques to improve their global competitive position. The lack of empirical research on these techniques with firm's performance is the reason to explain further their strategic values as management innovations in different types and sizes of organizations. From a theoretical foundation on the relations between innovation, strategy and performance, the following research questions were generated: (1) Are JITP and TQM positively related to the firm's performance?, (2) Do the combination/sequence of implementing JITP and TQM have a relation with the firm's performance?, and (3) Is the relationship between JITP and TQM to the firm's performance moderated by any of industry type, firm size,firm type and/or duration of JITP and TQM techniques? A model is developed and hypotheses are proposed. A survey is mailed to firms operating in the U.S. that have implemented one or both techniques. Questionnaire items measuring JITP, TQM, performance, and moderating variables - industry type, firm size,firm type, and duration of JIT purchasing and TQM techniques— are either developed or borrowed from other studies. From rosters of the American Society for Quality Control and the National Association of Purchasing Management, 1884 target respondents result in a 20.3 percent response rate. Reliability and factor analysis of the constructs are established. The research model is tested by canonical correlation analyses before a separate hierarchical regression analysis of sets is run for each of the three performance factors: financial and market, time-based quality and material productivity. The extent of JITP and TQM implementation positively and significantly relate with firm's performance. Furthermore, the relation between JITP and financial and market performance is higher in industries that face high foreign competition. Firm size, firm type and duration of JITP and TQM techniques are nonsignificant moderators. An improved research model is offered.

Computational Methods for Vulnerability Analysis and Resource Allocation in Public Health Emergencies

Indrakanti, Saratchandra 08 1900 (has links)
POD (Point of Dispensing)-based emergency response plans involving mass prophylaxis may seem feasible when considering the choice of dispensing points within a region, overall population density, and estimated traffic demands. However, the plan may fail to serve particular vulnerable sub-populations, resulting in access disparities during emergency response. Federal authorities emphasize on the need to identify sub-populations that cannot avail regular services during an emergency due to their special needs to ensure effective response. Vulnerable individuals require the targeted allocation of appropriate resources to serve their special needs. Devising schemes to address the needs of vulnerable sub-populations is essential for the effectiveness of response plans. This research focuses on data-driven computational methods to quantify and address vulnerabilities in response plans that require the allocation of targeted resources. Data-driven methods to identify and quantify vulnerabilities in response plans are developed as part of this research. Addressing vulnerabilities requires the targeted allocation of appropriate resources to PODs. The problem of resource allocation to PODs during public health emergencies is introduced and the variants of the resource allocation problem such as the spatial allocation, spatio-temporal allocation and optimal resource subset variants are formulated. Generating optimal resource allocation and scheduling solutions can be computationally hard problems. The application of metaheuristic techniques to find near-optimal solutions to the resource allocation problem in response plans is investigated. A vulnerability analysis and resource allocation framework that facilitates the demographic analysis of population data in the context of response plans, and the optimal allocation of resources with respect to the analysis are described.

Programming homeland security: Citizen preparedness and the threat of terrorism.

Register, David 08 1900 (has links)
This thesis tests the necessity of terrorism in articulating Homeland Security citizenship. Chapter 1 orients the study, reviewing relevant literature. Chapter 2 examines the USDHS Ready Kids program's Homeland Security Guide, mapping a baseline for how Homeland Security citizenship is articulated with the overt use of terrorism. Chapter 3 investigates the USDHS Ready Kids program, charting the logic of Homeland Security citizenship when the threat of terrorism is removed from sense making about preparedness. Chapter 4 compares the findings of Chapters 2 and 3, evaluating the similarities and differences between these two articulations of Homeland Security citizenship and concluding that the logic that cements Homeland Security into American society does not depend on the threat of terrorism against the United States.

An Investigation of the Relationship Between World-Class Quality System Components and Performance

Berry, Roger W. (Roger William) 12 1900 (has links)
Within the past two decades U.S. companies have experienced increased competition from foreign companies. In an effort to combat this competition many U.S. companies focused on quality as a solution to the problem. Researchers agree this emphasis on quality systems has changed the way many managers conduct business. Yet, no studies have identified which components of world-class quality systems, if any, contribute most to changes in performance. The purpose of this study is to empirically investigate three research questions pertaining to world-class quality systems: (1) What are the components of world-class quality systems? (2) Does a relationship exist between world-class quality system components and improved organizational performance? (3) Which world-class quality system components contribute most to changes in performance? The theoretical foundation for investigating these relationships is developed from Galbraith's (1977) information processing model of organization design. An extensive literature review resulted in the identification of seven components common to world-class quality systems: management involvement, customer involvement, employee involvement, supplier involvement, product/service design, process management, and continuous improvement. The literature suggests implementation of these components leads to changes in performance in such areas as productivity, throughput time, and quality output. A cross-sectional field study was used to gather data to answer the research questions. In this study, each component of world-class quality systems is measured as an independent variable. Change in productivity, throughput time, and quality output are measured as dependent variables. Factor analyses, correlation analyses, and hierarchical regression analyses are used to test the relationships. The target population was ISO 9000 certified companies located in the United States. The results indicated that management's involvement and employees' involvement are positively correlated with change in performance. The results also show that a positive relationship exits between the use of world-class quality system components and change in performance.

Towards modeling a long-term disaster recovery management

Unknown Date (has links)
Disasters are unavoidable. The United States separates the phases of addressing a disaster into Response and Recovery. There are systems in place for Response; but Recovery, a fundamental process for countries to rebound from disasters, is a topic that is left aside. Recently the U.S. released a framework regarding this topic and it is the intention of this work to further explore recovery by starting a modeling process for disaster management systems by developing a Disaster Recovery Roles Pattern based on the framework and creating flowcharts using the Business Process Modeling Notation for use in future development of systems for the recovery process. / Carlos A.
