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 ...


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 ...


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 ...
