  • In resolving industrial quality control problems, a vector of multiple quality characteristic variables is involved rather than a single variable. However, it is not guaranteed that a multivariate control chart based on statistical methods can monitor abnormal signal in case that small changes of relationship between each variables causes abnormal production process. Hence a quality control system for real-time monitoring of the multi-dimensional quality characteristic vector under a multivariate normal process is needed to enhance tile production system quality performance. A pattern analysis approach based on self-organizing map (SOM), an unsupervised learning technique of neural network, is applied to the design of such a quality control system. In this study we present a new material quality control system based on pattern analysis approach and illustrate the effectiveness of proposed system using actual electronic company material data.

  • The effectiveness of quality control is contingent to adaptability to the present circumstance. The objectives of this study are to provide empirical data to carry out qualify control effectively. To accomplish this purpose, an empirical study was made by questionaire (mailing survey method, Feb. to Mar. in 1987). The sample is the 167 companies in Korean manufacturing industry. The main findings out of the analysis are as follows the stage of quality control is concentrated in appraisal phase, the company standard is equiped gradually in non-KS marked company and the need of economic evaluation about quality control is increased gradually. With a view to analysing of relationship between quality control and it's effect factors (company standard, KS mark, computer based information system), the methods of $\chi$$^2$ test are used. The company standard have a significant difference in top manager's altitude to duality control, operation stage of quality control. operation scope of qualify control and quality budgeting system but is insignificant with economic evaluation about duality control. Otherwise, KS mark is insignificant with the equality control activity except for operation scope. The quality information system based in computer have a significant difference in operation stage, operation scope and economic evaluation. Therefor, for the purpose of attaining effectiveness of quality control through the economic evaluation about quality control, the company standard and computer based duality information system must be utilized in quality control activity.

  • In order to intensify an enterprise competition, quality inspection controls are very important issue. An organization or division of a company hopes which to acquire the quality inspection information be updated in real-time with respect to shop floor. In this paper, we develop a quality inspection control system for a Turbine/Generator production industry. The system compromises inspection scheduling module related to shop floor control (SFC) system, formal documentation control module, and formal inspection control module. In the quality inspection control system, ORACLE RDBMS is used for the database management system and ORACLE DEVELOPER 2000 is used for system development tool. The characteristic of this system is to support so it can enhance productivity and quality through inspection plans related to production scheduling.

  • This paper describes the method of establishing efficient system for the control of quality records. To establish the best control system of quality records, the organization must not only understand ISO Code requirements for quality record complectly but also identify the documents to be controlled as a quality records correctly. In addition, when establishing the system, the organization must absolutely consider the fact that quality records shall be maintained to demonstrate conformance to specified requirements and the effective operation of the quality system. This will provide the guidance which need to establish the system for quality control to the organization which produces documents in accordance with ISO Code requirements.

  • As the competition between countries has become higher and the notion of software quality has been widely spread. it has been necessary to develop technologies that can ensure and produce high quality software. With the advent of information-oriented society. quality control has to transfer to the quality control activities focused on software system instead of those activities focused on hardware system. If so, how do we get to handle the quality control on the basis of the new approach. Also, as software applications have grown, so too has the importance of software quality. In order to manage software quality, the technology to specify and evaluate both the software product quality and development process quality objectively quantitatively is most important. To produce products of good quality, we need a more progressive quality control system according to the need of software development life cycle. In other words, we do software right the first time or build quality in the process. On the basis intermediate and final time or build quality in the process. On the basis of data achieved, we can evaluate the products according to the consequences of the data, What are the problems to contrive the software quality control system?, we con promote the quality of products. To achieved that goal, we con provide a suitable the technique and method of software quality control.

  • 본 연구에서는 연약지반의 개량 및 부등침하가 일어난 건물의 복원 등에 사용할 수 있는 컴팩션 그라우팅 공법을 소개하였다. 기존 컴팩션 그라우팅 공법에서 사용되는 펌프는 1공씩 주입하는 시스템으로 시공 효율성이 저하되고,아날로그 주입방식으로 현장 작업자가 수동으로 시공을 관리하여 일관된 품질관리가 어려웠다. 기존 시공에서의 문제점을 해결하기 위하여 펌프와 품질관리 시스템을 개발하였다. 품질관리 시스템은 주입재료의 자동 배합 시스템, 다중 동시 주입 펌프, 주입관리 모니터링 시스템으로 구성하였다. 현장 시험을 통해 품질관리 시스템의 성능을 검증하였고 컴팩션 그라우팅 공법의 시험시공 후 품질 시험을 통하여 지반개량 성능을 확인하였다. 따라서 개발된 통합 품질관리 시스템을 활용한다면 시공 및 품질 확인이 어려운 현장에서 일관된 품질의 보장과 시공의 효율성 및 안정성을 향상시킬 수 있을 것으로 기대된다.

  • Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.
