Measures on Establishing Effective Quality Management System (QMS) in Information & Communication Industry
Lee, Deok-Soo ;
Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 1~8
The purpose of this study is to clearly understand the theoretical details of TL 9000 by researching the literatures and materials on TL 9000. Also, the paper studies the status of QMS building based on TL 9000 by researching and analyzing the positive cases of QMS established by companies on the basis of TL 9000 standards.
Spare Part Optimization of MIME Systems using Simulation and Genetic Algorithms under Availability
Chung, Il-Han ; Yun, Won-Young ;
Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 9~19
Spare part problem of MIME (Multi Indenture Multi Echelon) system under availability constraint has been studied for several decades. In most of existing studies, it was very difficult to obtain the optimal numbers of spare parts and some approximate methods were proposed under many restrictions. In this paper, we consider a simulation to estimate the total cost rate and system availability and a genetic algorithm to obtain the optimal numbers of spare parts. Some numerical examples are also studied.
Effects of Limited Capacity on Tolerance Design for Products With N-Type Quality Characteristics

Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 20~27
Tolerance design has been identified as an important research area and a number of models have been proposed in the literature. This paper investigates the effect of limited capacity on tolerance design for products with nominal-the-best type (N-type) quality characteristics. The model is developed under the assumption that the reprocessed and nonreprocessed items are produced by the same manufacturing process and therefore their quality characteristics are identically and independently distributed. Profit models are constructed which involve four price/cost components; selling price, cost incurred by imperfect quality, reprocessing and quality inspection costs. Methods of finding the optimal tolerance limits are presented, and a numerical example is given. Sensitivity analyses are also performed to study the effect of a process standard deviation on this model.
An Excel-Based Scheduling System for a Small and Medium Sized Manufacturing Factory

This study deals with an Excel-based scheduling system for a small and medium sized manufacturing factory without sufficient capability for managing full-scale information systems. The factory has the bottleneck with identical machines and unique batching characteristics. The scheduling problem is formulated as a variation of the parallel-machine scheduling system. It can be solved by a two-phase method: the first phase with an ant colony optimization (ACO) heuristic for order grouping and the second phase with a mixed integer programming (MIP) algorithm for scheduling groups on machines.
Structural Quality Defect Discrimination Enhancement using Vertical Energy-based Wavelet Feature Generation
Kim, Joon-Seok ; Jung, Uk ;
Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 36~44
In this paper a novel feature extraction and selection is carried out in order to improve the discriminating capability between healthy and damaged structure using vibration signals. Although many feature extraction and selection algorithms have been proposed for vibration signals, most proposed approaches don't consider the discriminating ability of features since they are usually in unsupervised manner. We proposed a novel feature extraction and selection algorithm selecting few wavelet coefficients with higher class discriminating capability for damage detection and class visualization. We applied three class separability measures to evaluate the features, i.e. T test statistics, divergence, and Bhattacharyya distance. Experiments with vibration signals from truss structure demonstrate that class separabilities are significantly enhanced using our proposed algorithm compared to other two algorithms with original time-based features and Fourier-based ones.

The importance of quality logistics service to the enterprises has kept growing considering the fierce competitions. It also asks for the sound definition and the scale explaining the construct of logistics service quality. The current study attempted to identify the construct of logistics service quality and develop the scale to measure it. Various qualitative and quantitative methodologies have been employed in order to provide the solid theoretical and psychometrical foundation of the proposed scale. In so doing, the conceptual definition of Logistics Service quality has been proposed and the 127-item scale measuring the construct of logistics service quality has been developed and found to be reliable and valid.
Continuous Quality Improvement of Medical Equipments Based on Clinical Monitoring: A Case Study of Dental Implants

Dental implant has recently become one of the most viable treatment options for regaining the oral function and dental aesthetics compared with conventional fixed or removable dentures. Dental implants vary in material, dimensions, geometries, surface properties, and interface geometries. It has been reported that there has been a proliferation of manufacturers who produce implants using various materials and surface treatments, and the dentist needs to select from over 2,000 different dental implants and abutments in a specific treatment situation. Unfortunately, however, no metrics have been specifically identified for the purpose of quality assessment and selection of an appropriate dental implant. This study aims to provide practical guidelines for quality assessment of dental implant based on clinical data. Like other medical devices and materials, the superiority related to specific characteristics of the dental implant needs to be verified through extensive clinical studies. The procedures of clinical monitoring for dental implants have been proposed along with a case study to exemplify the usefulness of clinical monitoring for the purpose of continuous quality improvement in medical industry.
Empirical Validation for Verbal- EBS Effect to Cognitive Stimulation
Kim, Jeong-Wook ; Jeong, Jong-Ho ;
Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 67~84
Given the industry's unprecedented attention and dedication of resources to voice recognition, this paper introduces and explores a novel idea generation technique whereby ideas are captured directly through verbalization rather than forcing group members to type ideas. A group simulator was used to measure the idea generation performance of individuals who input ideas verbally or via typing in the context of nominal and interacting groups. The results clearly indicate that verbal input represents a more desirable mechanism in a computer-mediated idea generation environment. Liberating group members from the keyboard produces remarkable performance gains. Verbalizing ideas helps individuals focus on analytical thinking and leverage group member ideas, ultimately facilitating the creation of ideas pools that are vastly superior in terms of quantity and quality. These effects were found across nominal and interacting groups. The implications of these results for future research and the design of technologies are discussed.
A Study on Service-Recovery Framework Affecting Process in Airline Service
Suh, Chang-Jeok ; Kang, Mi-Ra ;
Journal of the Korean Society for Quality Management, volume 36, issue 2, 2008, Pages 85~95
This research addresses examining the service recovery process in Airline service. A service recovery framework is suggested and tested empirically. The framework includes several factors such as service recovery expectations, service recovery achievements, recovery performance, post-recovery satisfaction, and post-recovery behavioral intents. The relationships among these factors are hypothesized and proved empirically. Consequently the results suggest that recovery expectation impacts on recovery performance significantly. Also the higher the recovery performance, the higher post-recovery satisfaction, then it increases customers' purchase intent and words of mouth. Finally, this paper suggests the need for new service recovery strategies.
