Inventory, Investment, And Pricing Policies For Lot-Size Decision Makers , Toshitsugu Otake Jan 1998

Inventory, Investment, And Pricing Policies For Lot-Size Decision Makers , Toshitsugu Otake

Retrospective Theses and Dissertations

In this dissertation, inventory, investment, and pricing policies for lot-size decision makers are examined based on classical economic order quantity. Specifically, we focus on investment in setup operations, investment in quality improvement, and market dependent products such as substitutes and complements. We examine various impacts of investment and competition on inventory policies and derive managerial insights and economic implications. Throughout this dissertation, deterministic mathematical programming is used as the primary analysis technique and optimal policies are obtained through this technique;For the inventory and investment relationships, we construct and analyze inventory and investment in setup operations policies, inventory and investment ...


Natural Language And Mixed Modality Task Presentations In The Human-Computer Interaction Using Programmable Logic Controllers , John Robert Wright Jr. Jan 1998

Natural Language And Mixed Modality Task Presentations In The Human-Computer Interaction Using Programmable Logic Controllers , John Robert Wright Jr.

Retrospective Theses and Dissertations

This dissertation focuses on the human-computer interaction elements of task presentation and task structure in the programming of Programmable Logic Controllers (PLCs). Task presentation methods that were explored included a natural language (GE Fanuc's State Logic), and a mixed modality language (GE Fanuc's Logicmaster Relay Ladder Logic). Task Structure elements utilized in this study were linear procedural tasks and conditional branching tasks;A two-level factorial analysis of covariance determined that task presentation was a significant contributor to programming development times. Task structure and the interaction between task presentation and task structure did not yield significant p-values at the ...


A Study To Ascertain The Viability Of Ultrasonic Nondestructive Testing To Determine The Mechanical Characteristics Of Wood/Agricultural Hardboards With Soybean Based Adhesives , Charles Raymond Colen Jr. Jan 1998

A Study To Ascertain The Viability Of Ultrasonic Nondestructive Testing To Determine The Mechanical Characteristics Of Wood/Agricultural Hardboards With Soybean Based Adhesives , Charles Raymond Colen Jr.

Retrospective Theses and Dissertations

There have been numerous studies with ultrasonic nondestructive testing and wood fiber composites. The problem of the study was to ascertain whether ultrasonic nondestructive testing can be used in place of destructive testing to obtain the modulus of elasticity (MOE) of the wood/agricultural material with comparable results. The uniqueness of this research is that it addressed the type of content (cornstalks and switchgrass) being used with the wood fibers and the type of adhesives (soybean-based) associated with the production of these composite materials;Two research questions were addressed in the study. The major objective was to determine if one ...


Profiting From Competition: Financial Tools For Electric Generation Companies , Charles William Richter Jr. Jan 1998

Profiting From Competition: Financial Tools For Electric Generation Companies , Charles William Richter Jr.

Retrospective Theses and Dissertations

Regulations governing the operation of electric power systems in North America and many other areas of the world are undergoing major changes designed to promote competition. This process of change is often referred to as deregulation. Participants in deregulated electricity systems may find that their profits will greatly benefit from the implementation of successful bidding strategies. While the goal of the regulators may be to create rules which balance reliable power system operation with maximization of the total benefit to society, the goal of generation companies is to maximize their profit, i.e., return to their shareholders. The majority of ...


Domain-Independent Method For Developing An Integrated Engineering Design Tool , Rebecca Lynn Sidler Kellogg Jan 1998

Domain-Independent Method For Developing An Integrated Engineering Design Tool , Rebecca Lynn Sidler Kellogg

Retrospective Theses and Dissertations

Engineering design is a complex, cognitive process requiring extensive knowledge and experience to be done effectively. Successful design depends on appropriate use of available resources. Competitive design cycles mandate convenient and reliable access to engineering tools and information. An integrated engineering design tool (IEDT) has been developed in response to these demands. Further, the tool development efforts have been made systematic by utilizing the engineering design process, which is shown to be a cognitive activity based on Bloom's taxonomy of cognition. The engineering design process consists of six tasks: establishment of objectives, development of requirements, function analysis, creation of ...


Benchmarking The Implementation Of Total Quality Management And Customer Satisfaction In General Automotive Repair Shops In Iowa , Hsiu-Te Sung Jan 1998

Benchmarking The Implementation Of Total Quality Management And Customer Satisfaction In General Automotive Repair Shops In Iowa , Hsiu-Te Sung

Retrospective Theses and Dissertations

The automotive repair industry was perceived by the American customers as an industry with high cost and low customer satisfaction. The purpose of this study was to identify the relationship between the level of total quality management (TQM) implementation and the level of customer satisfaction in the general automotive repair shops in Iowa. This information promised to enable the general automotive repair shops to increase service quality and customer satisfaction;A Total Quality System Implementation Assessment Instrument (TQSIAI) with 35 items was developed to measure the level of TQM implementation in the general automotive repair shops. A Customer Satisfaction Assessment ...


Service Identification And Allocation In Market-Based Power System Operation , Jian Fu Jan 1998

Service Identification And Allocation In Market-Based Power System Operation , Jian Fu

Retrospective Theses and Dissertations

In the market-based power system operation environment, ancillary services and other interconnected services are necessary to to maintain the secure and reliable operation of the transmission system. Service identification and allocation, together with congestion management, become important functions in the day- ahead scheduling of the independent system operator (ISO);In this dissertation, a general framework for service identification and congestion management was proposed. Based on a set of market model assumptions and the anticipated behaviors of the market participants, the individual profits of the market participants were analyzed. An overall profit maximization was proposed as the desired objective function. Because ...


The Analysis And Modeling Of Fine Pitch Laminate Interconnect In Response To Large Energy Fault Transients , Joel Arlen Jorgenson Jan 1998

The Analysis And Modeling Of Fine Pitch Laminate Interconnect In Response To Large Energy Fault Transients , Joel Arlen Jorgenson

Retrospective Theses and Dissertations

In embedded applications, the miniaturization of circuitry and functionality provides many benefits to both the producer and consumer. However, the benefits gained from miniaturization is not without penalty, as the environmental influences may be great enough to introduce system failures in new or different modes and effects;Of particular interest within this research is the effect of fault transients in reduced geometries of printed circuit card interconnect, commonly referred to as fine pitch laminate interconnect. Whereas larger geometries of conductor trace width and spacing may have been immune to circuit failure at a given fault input, the reduction of the ...
