JOURNAL RESTRICTED ACCESSIn the development phase, one of the important concepts is modularization. It is the purpose that modularization produces many products in the combination of a few modules. The representative examples are Scania's buses and tracks. Scaniais is the commercial vehicle maker of Sweden. In Scania, small numbers of modular components are combined, nevertheless various products are realized. In this paper, modular standardization is treated in the product development stage. That is, the standardization of the modules which constitutes the product profile is realized, so the developed modules are reduced and it accomplishes the new product development efficiency. After the important quality characteristic and the development targets are specifically determined by quality functional deployment, it opts for the composition of corresponding modules. In this paper the module standardization index is utilized, so it unifies modules. Its proposal is evaluated in terms of quality, cost, and development costs, so the optimal composition of the selected modules is realized.View full abstractDownload PDF (662K) -

JOURNAL RESTRICTED ACCESSQuality Function Deployment was proposed by Dr. Mizuno and Dr. Akao in 1960s and has been applied in many companies for fifty years. QFD is one of methodology to assure the product quality in the early stage of new product development process. The author considers that there were two changes in QFD history. The first was "Quality Table" and the second change was the linkage with the other product developing tools. In this research, author considers some subjects about QFD to change for the next generation, mainly focuses "Customer Requirement analysis", "Technology Deployment" and "QFD training and operation management".View full abstractDownload PDF (755K) -

JOURNAL RESTRICTED ACCESSJapanese manufactures have still been providing the high quality and high performance products to the world. However, they are often behind their competitors in developing the right product that customers really want. QFD define the relation between the requirement and the quality elements of the products, and show "what to make". Now this traditional solution that was born in more than 40 year ago should be noticed again for Japanese manufactures. On the other hand, the latest PLM (Production Lifecycle Management) systems including 3D-CAD, CAE and Digital-Manufacturing tool also has been evolving dramatically and giving huge benefits to the manufactures. This paper is trying to fuse QFD and PLM systems for showing the innovative product development process. Specifically, in the area of 1) product planning stage: fusion of QFD and Styling-Design & Virtual-Reality tools of 3D-CAD, 2) Systems Engineering and Model-Base-Engineering stage and 3) Detailed design stage.View full abstractDownload PDF (7733K) -

JOURNAL RESTRICTED ACCESSUp to now, the integration of QFD and other methods has been studied. For example, it is a method of extracting the bottleneck technology with QFD, and incubate the ideas with TRIZ, and designing robustness with Taguchi Methods (TM). QFD is used for transmission between each method. However, when I have participated in the place of design of experiment with TM in our company, the scene for which the result of QFD has been used enough was few. The main reasons are "The result of QFD is complex", "It takes time to execute QFD", "QFD is not executed.", and so on. Then, to increase the effect of using TM, I examined the method of executing QFD readily and effectively in the design of experiment. In this report, I propose the method of executing effective QFD to the extraction of control factor, and report on the effect confirmed by an actual experiment.View full abstractDownload PDF (6337K) -

JOURNAL RESTRICTED ACCESSFor a company to improve the performance of its organizational activities, it is important to clarify its goals and targets, share them among members concerned, and carry out its business operations. As a method to bring this approach into practice, we have been proposing the implementation of a process for planning effective and fast work processes. The planning involves correlating target items, which can be identified based on the company's missions and performance targets, with job functions to achieve the objectives as well as job assurance items as the indicators for managing the job functions. In addition, we focused on job functions for organizational innovation, which had been considered difficult to break down. We proposed a method to examine situations that can bring out intrinsic motivation in the members of an organization, identify specific job functions to stimulate such motivation through determining what functions can be encouraged by the organization as well as what roles can be played by its managers, and share and implement the identified job functions among relevant members.View full abstractDownload PDF (1111K) -

JOURNAL RESTRICTED ACCESSToday, manufacturers are faced with the problem of developing new product based on customer requirements. Because customer requirements are subjects to quick and unexpected changes, manufacturers must find a way to incorporate these variations as soon as they happen real-time. Generally, product development is begun by researching the VOC (Voice of customer) through questionnaires. Requirement management develops customer demand can be better predicted and created through requirement management from the manufacture's side. This paper indicates the fundamental concepts behind requirement management and which of them may help clarify customer demand from the manufacture's side. Additionally, the relationship between requirement management and quality function deployment is also clarified.View full abstractDownload PDF (577K) -

JOURNAL RESTRICTED ACCESSThe quality table is a tool widely used in the new product development. When we learn QFD for the first time, the quality table becomes basic of study. Therefore, the program of a lot of QFD educations adopts training that makes the quality table. However, people who attended QFD have the problem of not using the learnt knowledge if there is no chance to apply by the business. We considered the method of company training for which people who had attended QFD would use the quality table at once. As a result, because we adopted the quality table that can be written in one hour for company training, the case is shown.View full abstractDownload PDF (698K)

JOURNAL RESTRICTED ACCESSIn order to assure quality with limited available resources, hospitals have to develop healthcare delivery processes. Healthcare operation processes at hospitals are processes for delivering healthcare services to patients through medical practice such as surgery and medication. Since healthcare services have characteristics such as patients' variation, healthcare delivery processes are so complicated that healthcare staff cannot establish operation processes. In order to examine complicated operation process, it is useful to understand operation process as a connection of "standard modules". In terms of operation process, standard modules can be defined as best functions to achieve a purpose of the process. In this research, we develop a methodology to define standard modules for a surgery process. We define surgery process modules by function deployment of surgery process aims to achieve quality assurance with resource consumption efficiently. Finally we demonstrate adequacy and availability of standard modules through comparison with items of the standardized manuals in an actual hospital.View full abstractDownload PDF (1552K) -

JOURNAL RESTRICTED ACCESSMethodologies for designing noise-robust systems using statistical methods such as Design of Experiments are called "Robust Parameter Design". Taguchi Method is one of typical systematic approaches for Robust Parameter Design. The system with single signal and single response is the simplest target of Taguchi Method. Considering multi signals, there exist some merits such as comparison between signals, examining to realize broader target value and so on. Actually, there are a few arguments for designing a system with multi signals, but any of which never naturally generalize single signal argument from the viewpoint of regression analysis. This paper points out theoretical problems of existing methodologies and proposes a new methodology avoiding such problems, which is a natural generalization of the single signal case. Moreover, by analysing actual data, the proposed methodology is shown to be efficient not only for designing better solution but for exploiting the merits of multi signals.View full abstractDownload PDF (950K)

JOURNAL RESTRICTED ACCESSIn late years, many companies/organizations utilize moving image manual and improve quality of their operations. However, it is not necessarily clear what kind of moving image manual can ensure correct implementation of operations. This study took up two simple operations as examples, systematically varied expression methods of moving image manual using Design of Experiment, and investigated the number of the human error (deviation from the instructed operations) that occurred during operations. Based on the obtained data, it analyzed what expression methods of moving image manual are effective to reduce occurrence rate of human error. As a result, it was found that effective expression methods depend on type of operation, there are no conflicts between optimum conditions for each type of operation, and therefore low occurrence rate of human error can be realized by selecting appropriate conditions: e. g., angle form which operation is filmed, method of using zoomed images, color of caution message and method of inserting it, and method of using a chart that shows the overall flow of operation and images that show the purpose of operation.View full abstractDownload PDF (8141K)
