Equivalence testing and its applications in industry
Baik, Jai-Wook ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 1~6
As more and more data are collected one may ask whether the data collected within a short period of time are same. In this case traditional hypothesis testing of
is used to determine whether the data are same when there is no knowledge about equivalence testing. However, this type of hypothesis testing has the undesirable property of penalizing higher precision. So TOST is to be performed in the event of equivalence testing. In this study equivalence testing is introduced where one can find the applications in industry. Traditional two sample t testing is to be compared with the equivalent testing and the procedure to perform the equivalence testing is to be presented along with an example. Finally equivalence testing in terms of the other parameters such as variance, proportion or failure rate is to be sought.

Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 19~28
The purpose of this study is to search for the quality characteristics for evaluation of the information system. The quality characteristics are an important factor for selection, implementation and maintenance of the information system of the company. Of course in the end, the quality of the information system in a company is directly related with the business performance of the company. This paper is a study of a model with four independent variables, a parameter variable, and a total of 15 hypotheses, investigated by a questionnaire method. It conducted the model analysis of structural equation to use statistical package for questionnaire analysis.

A Comparative Analysis between Manufacturing and Transactional/Service Processes of Six Sigma Quality Improvement
Yoon, Jae-Wook ; Kim, Bo-Hyoung ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 37~46
There are big differences in six sigma projects between manufacturing processes and transactional/service processes. This paper analyzed the differences between the two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma case studies, step-by-step questions and check criteria were developed based on 12 step DMAIC methodology. On the basis of those characterized data, the differences between two areas were analyzed. Significant differences were found in the number of CTQs, validation of measurement systems, methods to determine improvement objectives, the methods to elicit improvement plans and types of control systems. The most significant difference was that statistical tools were widely used in manufacturing processes, but qualitative tools were used in transactional/service processes during improvement phase.
A Scale for Measuring Standardization of Service Encounter Process
Suh, Chang-Juek ; Lee, Se-Young ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 47~55
This study describes the creation of a scale to measure standardization for service encounter process. Measuring standardization of service encounter process is devided into manual level and action level. We investigate the relative impact of process standardization about service quality, job satisfaction and labor productivity. Our findings indicate that action level of service encounter process standardization is more important than manual level, and its process standardization positively affects service quality, job satisfaction and labor productivity positively.
The Effect of Management Quality on Firm Performance: Information Technology Effect
Roh, In-Sung ; Suh, Yung-Ho ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 56~64
Achieving sustainable performances is not an easy task in today's challenging environment. Since late 1980's, Baldrige Criteria for performance excellence has helped many organizations align their processes, their people, their resources, and their customers' needs. This study analyzes IT Quality effect on performances using Baldrige Criteria. Previous studies on Baldrige Criteria show the relationship between management quality and firm value.
A Study on the Integration of Local Public Enterprise Evaluation(LPEE) and Malcolm Baldrige Model(MBM)
Choi, Kil-Soo ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 65~76
The purpose of this study is to contribute to escalation of a management quality of local public enterprise through integrating local public enterprise evaluation(LPEE) and Malcolm Baldrige Model(MBM). In order to achieve the purpose, I suggested that develop an integration model of LPEE and MBM criteria and use AHP(Analytic Hierarchy Process) as a technique posting weight value to criteria. Of two suggests, it is the former to date or discuss seriously. Therefore the integration model is redesigned for leadership/strategy category(leadership, strategy), management system category(customer management system, business management system, measurement/knowledge management system), and management result category(business result, customer satisfaction result, human resource management result, financial management result).
Effects of Limited Capacity on Screening Procedures Using a Surrogate Variable
Choi, Ik-Jun ; Hong, Sung-Hoon ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 77~86
Due to the rapid growth in automated testing and manufacturing systems, screening inspection becomes very attractive. In this paper, we investigate the effects of limited capacity on screening inspection using a surrogate variable. 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 independently and identically 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 screening 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.
A note on CUSUM design for autocorrelated processes
Lee, Jae-June ; Lee, Jong-Seon ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 87~92
It is common to use CUSUM charts for detecting small level shifts in processes control, in which reference value(k) and decision interval(h) are the design parameters to be determined. To control process with autocorrelation, CUSUM charts could be applied to residuals obtained from fitting ARIMA models. However, constant level shifts in processes lead to varying mean shifts in residual processes and thus standard CUSUM charts may need to be modified. In this paper, we study the performance of CUSUM charts with various design parameters applied to autocorrelated processes, especially focussing on ARMA(1,1) models, and propose how they can be determined to get better performance in terms of the average run length.

Kim, Hong-Min ; Chung, Byung-Hee ;
Journal of the Korean Society for Quality Management, volume 36, issue 4, 2008, Pages 93~101
The rare metals, used for semiconductors, PDP-LCS and other specialized metal areas necessarily, has been playing a key role for the Korean economic development. Rare metals are influenced by exogenous variables, such as production quantity, price and supplied areas. Nowadays the supply base of rare metals is threatened by the sudden increase in price. For the stable supply of rare metals, a rational demand outlook is needed. In this study, focusing on the domestic demand for chromium, the uncertainty and probability materializing from demand and price is analyzed, further, a demand forecast model, which takes into account various exogenous variables, is suggested, differing from the previously static model. Also, through the OOS(out-of-sampling) method, comparing to the preexistence ARIMA model, ARMAX model, multiple regression analysis model and ECM(Error Correction Mode) model, we will verify the superiority of suggested model in this study.

The most widely used models to study the quality of service are the SERVQUAL and SERVPERF models that measure service mechanisms. This paper is to estimate service efficiency and consistency for Retail Industry. We tried to measure the service quality and overall satisfaction by using DEA and PCI, degree of combination and top2box which is a little bit different methodology from traditional ones. Rather than using the usual method of converting the service quality index by mean value, the Service Efficiency Index(SEI) and Service Quality Consistency Index(SQCI) are used to measure the efficiency and consistency level, which in turn can be used as the new service quality indices. The result of SEI and SQCI show the efficiency frontier in retail industry that 6 DMUs are analyzed relative efficient DMUs, 12DMUs are inefficient DMUs and retail Industry consistency level appeared low(0.35-0.47) Also, there is a significant difference in terms of efficiency and consistency in the each retail industry. Finally, we showed the summarized result as the Effi-Con Matrix
