Bae, Jinhan ; Song, HaeGeun ; Park, Young T. ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 623~635
DOI : 10.7469/JKSQM.2013.41.4.623
Purpose: The recent major recalls of hazardous products caused consumer product safety acts to be strengthen worldwide. Although the recall system of hazardous products in Korea has been operating based on Framework Act on Product Safety since 2011, the evaluation of product risk has been relied on not the results of objective incident data but the results of illegal product investigations. The purpose of this paper is to propose a product risk assessment model for Korea using injury data. Methods: The authors derived Korea`s risk assessment method by analysing the advantages and disadvantages of the most widely used models in advanced countries such as EU`s RAPEX RAG and Janpan`s R-MAP. In this study, the level of relative frequency and severity of injury are determined based on the objective incident data and the length of hospitalization respectively. In addition, the injury data occurred during 2011 is applied to the proposed risk assessment model for case study. Results: The data analysed in this paper can be classified as high risk, medium risk, low risk, acceptable risk, and safe products through the matrix f rom the combination of the relative frequency and the severity derived. Conclusion: The proposed risk assessment model in this study has advantage obtaining reliable objective results because it uses actual injury data and redeems the drawbacks of the existing models used in advanced countries. Furthermore, because the proposed model shows the high risk products among many, it is expected to be useful especially for customs whose main job is inspecting the imported goods and the government when selecting the target product groups for safety investigation.

DOI : 10.7469/JKSQM.2013.41.4.659
Purpose: The purpose of this study was to estimate life time of halogen lamps and acceleration factors using accelerated life test. Methods: Voltage was selected as an accelerating variable through the technical review about failure mechanism. The test was performed at 14.5V, 15.5V and 16.5 for 4,471 hours. It was assumed that the lifetime of Halogen lamps follow Weibull distribution and the inverse power life-stress relationship models. Results: Mean lifetimes of pin and screw types were 19,477 hours and 6,056 hours, respectively. In addition, acceleration factor of two items are calculated as 4.8 and 2.2 based on 15.5V, respectively. Conclusion: The life-stress relationship, acceleration factor, and MTTF at design condition are estimated by analyzing the accelerated life test data. These results suggest that voltage was very important factor to accelerate life time in the case of halogen lamps and the life time of pin type is three times longer than screw type lamps.

Kim, Young Jin ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 673~681
DOI : 10.7469/JKSQM.2013.41.4.673
Purpose: The purpose of this study is to investigate the design optimization modeling of screening procedures based on the assessment of misclassification errors. Methods: Misclassification errors due to measurement variability are derived for normally distributed quality characteristics. Further, an optimization model for ensuring the level of outgoing quality is proposed and demonstrated through an illustrative example. Results: It is shown that two types of misclassification errors (i.e., false acceptance and false rejection) may be properly compromised through an analytical assessment of measurement errors and an optimization modeling. It is also discussed that a variety of optimization modeling may be enabled based on the derivation of measurement errors. Conclusion: It may be concluded that the design of screening inspection may further be facilitated by including the effect of measurement errors on the performance of screening inspection procedure.

Kim, Hakgyun ; Song, HaeGeun ; Park, Young T. ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 683~692
DOI : 10.7469/JKSQM.2013.41.4.683
Purpose: Car seats affect customer satisfaction greatly when the seats` design is changed because car holders are in close contact with the seats. However, the improvement of the current seats` design involves risks such as investment cost, and therefore it needs strategic operating measures from the perspective of customers. Until now, operations of seats` specification have been decided by technical-push rather than market-pull, and carried out based on professionals` experience without measuring customer satisfaction correctly. The purpose of this study is to present a systematic approach to measure customers` perception on the car seats using the Kano model and pairwise comparison technique. Methods: The authors derive 17 major functions of a car seat by analyzing major components of car seats, and conduct a survey of 141 adults who hold a car(s). Results: The results show that consumers perceive the adjustable functions of front seats as must-be while the same functions for rear seats are perceived as attractive. In particular, motor operated functions for both front and rear seats increase customer satisfaction greatly if they are presented. Conclusion: This study shows that how much customer (dis)satisfaction will increase if a function of car seats (non)fulfilled, and therefore, the results of this study will provide practitioners and R&D personnel in new automobile seats development projects with useful information.
A Study on Analysis of the Implementation Status and the Advancement of Computerized Maintenance Management System (CMMS) in Korean Companies
Ku, Sung Tae ; Kim, Chang Eun ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 693~708
DOI : 10.7469/JKSQM.2013.41.4.693
Purpose: This study is to develop an evaluation model for analysis of CMMS Implementation status and provide CMMS advancement methods to maximize implementation effect through the evaluation model. Methods: After extracting common modules from CMMS packages and establishing evaluation standard for each module, then the evaluation standard is applied to 33 Korean companies for evaluating their own current implementation status. Results: Preventive maintenance and analysis information modules were considered the most vulnerable in Korean companies which have introduced CMMS packages. And the reason why preventive maintenance is vulnerable is that there is poor build-up of their own preventive maintenance standards. Conclusion: Korean companies which will introduce CMMS need to make preventive maintenance standards, and data of the materials and the equipment to improve the effectiveness in advance.
Effects of Normalization and Aggregation Methods on the Volatility of Rankings and Rank Reversals
Park, Youngsun ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 709~724
DOI : 10.7469/JKSQM.2013.41.4.709
Purpose: The purpose of this study is to examine five evaluation models constructed by different normalization and aggregation methods in terms of the volatility of rankings and rank reversals. We also explore how the volatility of rankings of the five models changes and how often the rank reversals occur when the outliers are removed. Methods: We used data published in the Complete University Guide 2014. Two universities with missing values were excluded from the data. The university rankings were derived by using the five models, and then each model`s volatility of rankings was measured. The box-plot was used to detect outliers. Results: Model 1 has the lowest volatility among the five models whether or not the outliers are included. Model 5 has the lowest number of rank reversals. Model 3, which has been used by many institutions, appears to be in the middle among the five in terms of the volatility and the rank reversals. Conclusion: The university rankings vary from one evaluation model to another depending on what normalization and aggregation methods are used. No single model exhibits clear superiority over others in both the volatility and the rank reversal. The findings of this study are expected to provide a stepping stone toward a superior model which is both reliable and robust.
Development of the ISEP Based on Systems Engineering
Byun, BoSuk ; Choi, YoChul ; Park, Young T. ;
Journal of the Korean Society for Quality Management, volume 41, issue 4, 2013, Pages 725~735
DOI : 10.7469/JKSQM.2013.41.4.725
Purpose: The purpose of this study is to propose an Integrated Safety Evaluation Process (ISEP) that can enhances the safety aspect of the safety-critical system. This process utilizes the advantages of the iterative Systems Engineering process combined with the safety assessment process that is commonly and well defined in many standards and/or guidelines for railway, aerospace, and other safety-critical systems. Methods: The proposed process model is based on the predefined system lifecycle, in each phase of which the appropriate safety assessment activities and the safety data are identified. The interfaces between Systems Engineering process and the safety assessment process are identified before the two processes are integrated. For the integration, the elements at lower level of Systems Engineering process are combined with the relevant elements of safety assessment process. This combined process model is represented as Enhanced Functional Flow Block Diagram (EFFBD) by using CORE(R) that is commercial modelling tool. Results: The proposed model is applied to the lifecycle and management process of the United States aircraft system. The US aircraft systems engineering process are composed of twelve key elements, among which the requirements management, functional analysis, and Synthesis processes are considered for examplenary application of the proposed process. To synchronize the Systems Engineering process and the safety assessment process, the Systems Engineering milestones are utilized, where the US aircraft system has thirteen milestones. Taking into account of the nine steps in the maturity level, the integrated process models are proposed in some phases of lifecycle. The flows of processes are simulated using CORE(R), confirming the flows are timelined without any conflict between the Systems Engineering process and the safety assessment process. Conclusion: ISEP allows the timeline analysis for identifying activity and data flows. Also, the use of CORE(R) is shown to be effective in the management and change of process data, which helps for the ISEP to apply for the development of safety critical system. In this study, only the first few phases of lifecyle are considered, however, the implementation through operation phases can be revised by combining the elements of safety activities regarding those phases.
