  • Purpose: This study is in order to secure high quality of military supplies, it is important to secure design quality in the development phase. I will review how to establish a quality assurance system in the development phase based on the author's seminar presentation contents and application example of Hanwha Systems Co., Ltd. Methods: To guarantee design quality in the development phase, in 2002, quality assurance system that is adequate for SQA(Software Quality Assurance)'s requirements of CMM(Capability Maturity Model) was conduct. In 2009, based on the CMMI(Capability Maturity Model Integration) Level 5, there has been continuous and reenforced quality assurance activities. Results: By suggesting the construction and a case study on application of R&D quality assurance, it would be helpful for companies aiming to construct or enhance quality assurance system. Conclusion: To secure high quality for military supplies, a development QA system should be established to secure quality in the development phase. In addition, Total life cycle QA system for development, mass production and operation phase should be reestablished.

  • Quality is defined as several terms of fitness for use, conformance to requirements or specification, and loss of social effect. And the quality can be classified into design, production and service quality according to its formation of product (or servece). To be satisfactory product, the product must be controlled to maintain the specified level of quality at the whole life cycle of R&D step through disposal step. And the wrong design is one of the great source of cost. Therefore, the quality assurance on the R&D step is very important. This paper suggests a general procedure for the R&D quality assurance and discusses the methods for the reliable design. And a telecommunication equipment is considered as an applied example. Finally, it is discussed some subjects on the R&D quality assurance as further researches.

  • There are several models for process quality assurance by quality system(ISO 9000), process capability analysis, acceptance control chart and so on. When a high level process capability has been achieved, it takes a long time to monitor the process shift, so it is sometimes necessary to develop a quicker monitoring system. To achieve a quicker quality assurance model for high-reliability process, this paper presents a model for process quality assurance when the fraction nonconforming is very small. We design an acceptance control chart based on variable quality characteristic and time-censored accelerated testing. The distribution of the characteristics is assumed to be normal of lognormal with a location parameter of the distribution that is a linear function of a stress. The design parameters are sample size, control limits and sample proportions allocated to low stress. These parameters are obtained under minimization of the relative variance of the MLE of location parameter subject to APL and RPL constraints.

  • To achieve software quality and human-centred design for electronic ship navigation called e-navigation, an international guideline of software quality assurance and human-centred design was approved in 2015. Usability is a common goal of both software quality assurance and human-centred design as developing e-navigation system and software developments. Therefore, research is needed to evaluate the usability of e-navigation systems and software such as metrics that can use usability testing. This paper derives effectiveness metrics for e-Navigation usability testing based on international standards. The research method is to analyses and compares the effectiveness measurement and metrics in ISO 9241-11 for human-centered design and ISO/IEC 25022 and 25023 for software quality to find out measurements and metrics being defined commonly. The derived metrics are applied to Electronic Chart Display and Information System as a case study based on performance standard.

  • A prerequisite for improving the quality of a product is to enhance the quality of its parts supplied from outsourced enterprises. An enterprise certified by ISO 9001 Quality Management System is expected to develop their effective quality assurance system and maintain it through continuous control and improvement, thereby ensuring the good quality of products that they produce. However, it is reported that small and medium-sized enterprises certified by ISO 9001 have difficulty establishing an effective quality assurance system. This study aims to propose a new method of improving a quality assurance system that can be more effective in small and medium-sized enterprises. This study collectively considered requirements specified in several international standards on quality system and the results of expert group brainstorming to identify evaluation areas and items for assessing a quality assurance system. Based on these evaluation areas and items, a set of checklists for diagnosing and improving a quality assurance system was developed. In order to demonstrate the usefulness of the proposed method, this study applied it to ten small and medium-sized enterprises and could identify four approaches for improving their current quality assurance system. The presented improvement method, which consists of establishment of quality goals and quality innovation plan, defective products corrective activities, 4M and design change process, improvement of customer quality information management, is expected to be utilized as a useful tool for the enhancement of the quality assurance system of small and medium-sized enterprises.

  • Since the safety accidents on the construction sites take large part of total industry disasters, research on the construction safety has been getting important. Recently, as BIM technology allows cooperation between designer and constructor groups, it becomes more active worldwide than before to study on the ways of accomplish construction safety improvement in the design phase. In this paper, we suggested a checklist for assuring construction safety in the phase of design, and performed automatic evaluation by using a BIM quality checking tool. This shows that it is possible for us to find out the construction safety has been improved in the design phase. Once the standard checklist and assurance process are developed, they are expected to play a great role of reducing disasters in the construction industry.
