The determination of appropriate buffer capacity is an important issue in the design of the advanced manufacturing systems and closely related to the system efficiency and flexibility. Work-in-process is usually not desirable. However, in reality, maintaining some capacity of buffer storage is inevitable in compensation for the machine blocking and break down. The objective of this paper is to present analytical methods and tools for the buffer capacity planning in the Flexible Manufacturing System Environments. The effects when machine blocking is critical factor are also discussed.

This study developed a model to evaluate the quality management system of a medical device manufacturing company, and applied it to medical device manufacturers to understand the impact on business performance in response to international regulations and industry's change. This study prepared preliminary items, defined four (4) major factors (Plan-Do-Check-Act) that consist of the evaluation layers and items per category according to prior research review and expert interview, and calculated the weight and importance using AHP. The study results showed that responsibility & authority and quality objective in Planning Category, product-related requirement and R&D in Doing Category, Measuring and monitoring in Check Category, and review of meeting Regulatory and regulation in Action Category are relatively more important factors. The evaluation model developed based on the calculated weight and importance to business performance was applied to medical device manufacturers to investigate and analyze the implementation level of QMS and its impact on business performance according to each category. Most medical device manufacturers to be studied showed a reasonable level of QMS and effective business performance. Almost all the evaluation layers and items in the four (4) factors had a significant influence on business performance. Although the medical device quality management system is aimed mainly at license acquisition, it is important that management environment factors not related directly to licensing and authorization are important to business performance, and it is effective when these factors are integrated and operated within and outside the manufacturer.

Projects to deploy and diffuse smart factories in South Korea are aimed at enhancing national manufacturing competitiveness. However, a significant portion of deployed companies remain at the basic stage and struggle to utilize smart factories regularly. Existing studies have primarily focused on the technical aspects of smart factories, using data analytics and case studies, leading to a gap in empirical research on continuous use and upgrade intentions. This study identifies key factors influencing smart factory usage and user satisfaction, drawing on the Information Systems Success Model (ISSM) and previous research. It empirically examines the impact of these factors on continuous use intention, management performance, and advancement acceptance intention through smart factory usage and user satisfaction. A structural equation model is employed to validate the research hypotheses, using survey data from 287 small and medium-sized manufacturing enterprises (SMEs) that have adopted smart factories. Results demonstrate that system quality, information quality, service quality, and government support significantly affect smart factory usage, while service quality and government support influence user satisfaction. Furthermore, smart factory usage and user satisfaction have positive effects on management performance, continuous use intention, and subsequently advancement acceptance intention. This study provides novel insights by demonstrating the specific impact mechanisms of smart factory user satisfaction on the business and the intentions of manufacturing SMEs regarding continuous use and advancement acceptance, leveraging the ISSM.

The purpose of this study is to verify the effects of information system quality on business performance (net benefit) in the Korean public informatization business and to verify whether the user has mediating role in the relationship between information system quality and net benefit. In order to prepare empirical tests, factor analyses was conducted and the validity and reliability of the variables were confirmed to be acceptable. The research hypotheses were tested by regression analyses. The mediating effects as well as the main effects were analyzed by SPSS statistical program. The results show that the higher the quality of the information system becomes, the higher the usability by the users of the system increases. Also, it was found that the users had more positive effect on the net benefit of the public informatization project. In addition, it was confirmed that there was a partial mediating effect by the users on the relationship between information system quality and the benefits. The results of the research suggests that we establish a management system to improve the business performance efficiently according to the priorities of detailed success factors from the viewpoint of the public information business, and the users who use the information system quality and system.

품질관리(品質管理)가 단순(單純)히 품질(品質)을 관리(管理)하는 통계적(統計的)인 수법(手法)으로서의 역할(役割)을 벗어나 경영관리(經營管理)의 새로운 시스템으로서 등장되던 1960년 전후부터 품질보증(品質保證)(quality assurance:QA)의 중요성(重要性)이 점차(漸次) 높아지게 되었다. 1959년(年)에 미국(美國)의 자동차업계(自動車業界)에서 시작(始作)된 마일에이지 보증(保證)(mileage warranty)이나, 이어서 보급된 내구소비재(耐久消費財)의 1년 보증제(保證制) 등이 QA의 발달(發達)의 계기(契機)가 되었다. 뿐만 아니라 점점 복잡화 되어가고 있는 제품(製品)에 대(對)한 안전성(安全性)이 강하게 요청(要請)되고 있다거나, 소비자(消費者)의 제품(製品)에 대(對)한 뉴스가 다양화(多樣化)되어 온것도 QA의 용요성(用要性)이 일반(一般)에게 인식(認識)되기 시작(始作)한 요인(要因)이었다고 생각한다. 이때부터 품질보증(品質保證)이라는 말이 널리 사용(使用)되어 왔다. 그러나 그 말을 사용(使用)하는 사람에 따라 뉴안스를 달리하는 경우가 많다. 즉 품질보증(品質保證)이라는 말의 해석(解釋)이 구구하다. 품질보증(品質保證)이란 무엇을 의미(意味)하는가, 그리고 품질보증(品質保證)의 방법(方法)은 어떤 것인가에 대(對)해 부족(不足)하나마 평소(平素)에 가지고 있던 생각을 여기에 정리(整理)해 볼까 한다.
