The high cost in maintaining complex manufacturing process makes it necessary to enhance an efficient maintenance system. For the effective maintenance of manufacturing process, precise fault diagnosis should be performed and an appropriate maintenance action should be executed. This paper suggests an intelligent fault diagnosis system using hybrid data mining. In this system, the rules for the fault diagnosis are generated by hybrid decision tree/genetic algorithm and the most effective maintenance action is selected by decision network and AHP. To verify the proposed intelligent fault diagnosis system, we compared the accuracy of the hybrid decision tree/genetic algorithm with one of the general decision tree learning algorithm(C4.5) by data collected from a coil-spring manufacturing process.

It is critical to select an appropriate technology valuation method when the characteristics of a technology and valuation environment are variable. To ensure high quality decision making when selecting a technology valuation method, it is necessary to understand the principles of a good technology valuation method, and define and apply a decision making theory for selecting an optimal method. The authors propose that Axiomatic Design Principles can be applied as a decision making theory. In order to apply Axiomatic Design for this problem, this paper describes four domains(customer, functional, physical, and process domain) and four axioms(independence, information, cost, time axiom) for the decision making process for the optimal technology valuation method. The result of this study will contribute flexibility to the dynamic technology valuation process.

It is the purpose of this study that propose method to estimate weights of decision-making for design concepts considering characteristics of places. In order to acquire these weights of concepts, the investigation with questionnaire by AHP(Analytic Hierarchy Process) is employed as a mean. Targets of this investigation was 63 respondents which were graduate students(21) and experts of design field(42). As a result, we could find differences between these weights of the relative concepts and know the differences in the weights of design concepts as characteristics of places were reflected. These weights of concepts will be take opinions about concept from design-related members into consideration. Therefore, In design process, the weights of design concepts will help for designer to verify the concepts in design initially, and finally be used by a criteria in decision-making. The Weights of decision-making for design concepts as a result of this study will be used as a guideline for the systematical and conceptual approach in design practice.

Presently, Analytic Network Process which evaluates man's intention and offers decision-making support is capturing the spotlight. It originates in the ability of Analytic Network Process to treat various decision-making support system. However, no detailed reference is available when dealing with the group case. This paper examines the technique, which can also cope with the group decision-making support system, and describes the validity of the technique. A characteristic feature of the proposed technique is that it can detect a group's intention in a given section, and it decomposes the sectional supermatrix into a small supermatrix and a large one. A general supermatrix treats the convergence value by taking the limiting process method of the power of an evaluation value. On the other hand, when a supermatrix has nonnegative value, it can easily be solved by the eigenvector method. The decomposition of the supermatrix has been considered in this work.

The purpose of this study was to analyze the relationship and the importance of relevant variables among structure, process, and outcome dimensions of nursing department in hospitals. The subject for this study was the registered nurses(N=400) working in medical, intensive care, and surgical units at 5 general hospitals with more than 500beds in Chungnam and Chungbuk. The research design was cross-sectional correlation among the variables based on their self description. The survey instrument was based on eleven structured questionnaires. The data were collected from April 26 to May 26, 1999. The SPSS/PC+ program and LISREL 8.12a program were used to analyze the data. Based on the data collected, the following results were obtained. The relationship among structural, procedural, and outcome dimensions 1. Structural dimension had a relationship with procedural dimension relating to decision-making of caregiving and working conditions, in particular, participation of the problem identification. 2. The extent of participation in decision-making had a relationship with organizational commitment and group effectiveness through the selection process among the total decision-making processes. 3. The structural dimension had a large direct effect rather than indirect effect through decision making processes on organizational commitment and group effectiveness. The relationship of structure, process, outcome dimensions was partially supported by this study. The information obtained from surveys in the field form the basis for the following recommendations for improving organizational effectiveness with in the nursing department in an hospitals. 1) Establishment of decentralized structure, environment, and culture in organizational settings would be desirable so that their members may actively participate in decision-making process. 2) Continuous education and training of nurses with theoretical Knowledge and skill of decision making, practical knowledge, and upright role perception should be highly emphasized for persons in nursing schools and in on-the-job training.

The purposes of this study are to identify the characteristics of limited edition fashion consumers, to analyze their purchase decision-making processes, and to examine negative factors of consumers' recognition toward limited edition fashion products. A qualitative investigation was conducted by doing in-depth interviews with 11 selected consumers in their twenties and thirties who have actively purchased and consumed limited edition fashion products. The results of this study can be summarized as follows. First, there are four sub-categories of appearance management activity, acceptance of fashion trend, information-seeking behavior, and hedonic shopping orientation for the limited edition fashion consumers' characteristics. Second, the purchase decision-making process of limited edition fashion consumers are identified as seven steps: need recognition, information search, evaluation of alternatives, planning and courtship, purchase, post-purchase evaluation, and post-purchase behavior. Courtship/attachment formation and post-purchase behavior are unique steps when compared to general purchase decision-making process. Third, this study identified negative factors of consumers' recognition toward limited edition this study in order to suggest several improvement plans for enterprises using limited marketing. Four sub-categories are examined: outrageous price, tricks of company, fatigue due to purchasing competition, and re-sellers. In conclusion, this study indicates that the purchase decision-making process of limited edition consumers, which involves two distinctive steps including courtship/attachment formation and post-purchase behavior, can be differentiated from general consumers. The results of this study provides preliminary data for further research for in-depth analysis of limited edition consumers.

This study investigates the decision-making processes of Iranian women in their twenties who purchased Hallyu beauty and fashion products. We conducted ten in-depth interviews of Hallyu enthusiasts who previously purchased Hallyu products. Interviewees were recruited using a snowball sampling technique based on nonprobability sampling. Interviews were conducted in the 1:1 in-depth interview format for one hour of each interview from April 11, 2017, to May 14, 2017, using semi-structured questionnaires, and recorded with consent. Our analysis of the characteristics of consumption behaviors of the women used seven steps of the purchase decision-making process. This study used interviews to analyze the following questions. Research Question 1. What is the decision process for Iranian women's consumer products purchase? Research Question 2. What are the characteristics and meaning of each stage of Iranian women's consumer decision-making process? Data collection in this study was limited to participants in their twenties; however, this research will be helpful for future Hallyu and Iranian consumer analysis. A follow-up study should examine the purchasing decisions of women in additional age groups in order to generalize the results.

Electronic Records Management System (ERMS) is a computer program or set of applications that is utilized for keeping up to date records along with their storage. ERMS has been extensively utilized for enhancing the performance of academic institutions. The system assists in the planning and decision-making processes, which in turn enhances the competencies. However, although ERMS is significant in supporting the process of decision-making, the majority of organizations have failed to take an initiative to implement it, taking into account that are some implementing it without an appropriate framework, and thus resulted in the practice which does not meet the accepted standard. Therefore, this study identifies the factors influencing the adoption of ERMS among employees of HLI in Yemen and the role of such adoption in the decision-making process, using the Unified Theory of Acceptance and Use of Technology (UTAUT) along with Technology, Organization and Environment (TOE) as the underpinning theories. The study conducts a cross-sectional survey with a questionnaire as the technique for data collection, distributed to 364 participants in various Yemeni public Higher Learning Institutions (HLI). Using AMOS as a statistical method, the findings revealed there are significant and positive relationships between technology factors (effort expectancy, performance expectancy, IT infrastructure and security), organizational factors (top management support, financial support, training, and policy),environmental factors (competitiveness pressure, facilitating conditions and trust) and behavioral intention to adopt ERMS, which in return has a significant relationship with the process of decision-making in HLI. The study also presents a variety of theoretical and empirical contributions that enrich the body of knowledge in the field of technology adoption and the electronic record's domain.

Although the related regulations or guidelines are not specified in the defense weapon system R&D process, R&D authorities frequently encounter problems that require rational decision-making. If the rational process is not applied in the matter of alternative choice, the project could be disrupted, which can result in longer project periods or more resource provision. In particular, a variety of decision-making methods are needed for test&evaluation of missile R&D. The issue of selecting a test site is one of the representative decision-making problems. If it is needed to determine the priority of multiple sites, Delphi Method and Analytic Hierarchy Process(AHP) will be applied. However, if the input of cost is to be considered, Data Envelopment Analysis(DEA) is more valuable to solve the problem. This paper proposes a solution to handle quantitatively various decision-making problems that can occur in missile flight test, and shows how DEA is applied through a simulated case study of selecting a foreign test site.
