Today's fierce competition and global economic recession make most of manufacturing companies in the world difficult to gain a profit. In order to survive such a environment and increase competitiveness, manufacturing companies have to continuously eliminate their wasteful factors through an efficient process analysis, improve quality of products, increase the flexibility of manufacturing processes. In this paper, we consider a case study for the Shanghai New Auto which is a subcontractor of MOBIS in China, to improve productivity by using therblig method, one of the motion analysis, to minimize the work-in-process inventories and to shorten the manufacturing cycle times. We also try to relocate the facility layout to increase the efficiency and flexibility of manufacturing processes.

The purpose of this study is to examine the success factor of Quality Management (QM) in the manufacturing conditions aspect of medium and small-sized sanitary enterprise. The requisite for manufacturing factors are classified into manufacturing human factors (the number of production employee, training and teaching, discuss on quality, manufacture expertness, etc.), manufacturing facility factors (coating, hardening, and molding equipment), manufacturing core component factors (temperature and viscosity, line, surface). And the indicator of quality outcomes are measured by reorder and recommendation to others.

The product process is sequence of all the required activities that a company must perform to develop, and manufacture a product. These activities include marketing, research, engineering design, quality assurance, manufacturing, and a whole chain of suppliers and vendors. The process also comprises all strategic planning, capital investments, management decisions, and tasks necessary to create a new product. manufacturing processes must be created so that the product can be produced in the product facility Purchasing new equipment and training workers may be required if new technology is to be used. Tools, fixtures, and the sequence of steps in the manufacturing processes must all be developed to allow rapid, high-quality, cost effective production. Also, it may be needed to be rearrange the production facility to adapt to the new manufacturing processes. Therefore, this study tries to proposed that Scheduling by customer needs group for minimizing the problem and reducing inventory, product development time, cycle time, and order lead time.

4차 산업혁명 시대를 맞아, 제조 기업들은 생산성 향상을 위해 축적된 설비 데이터를 활용하여 스마트제조를 실현하는 것에 높은 관심을 두고 있다. 하지만 기존의 설비 데이터 분석 연구들은 주로 센서 데이터 등 정형 데이터를 대상으로 하여, 실제 큰 비중을 차지하고 있는 텍스트와 같은 비정형 데이터에 대한 분석 연구는 부족한 실정이다. 특히, 작업자가 수기로 작성한 텍스트 데이터를 활용한 사례는 매우 적었다. 따라서 본 논문에서는 작업자가 수기로 작성한 설비 오류 데이터를 분석하여 연관 규칙 마이닝을 통해 설비 오류 발생 패턴을 도출하는 프레임워크를 제안하고자 한다. 이때, 일반적인 텍스트 분석 기법과 같이 단어를 분석 기준으로 사용하는 경우 전문 용어에 해당하는 설비 오류의 의미를 표현하는 데에 한계가 있다는 점에 착안하여 구절을 추출하여 텍스트 분석 기준으로 사용하였다. 제안하는 프레임워크의 성능을 실제 사례를 통해 검증하였으며, 본 연구 결과를 활용하면 설비 오류를 예방하여 가동률을 높이고 나아가 제조 기업의 생산성 향상에 기여할 수 있을 것으로 기대한다.

Recently, for the purpose of maintenance of facilities and energy, there have been growing cases of the 3D image scan-based reverse design technology mostly in the manufacturing field. In the MEP field, because of differences between design and physical model, the reverse technology has been utilized in factory facilities such as a semiconductor factory. Because 3D point clouds from scanning include accurate 3D object information, the efficiency of management works related to the complex MEP facilities can be enhanced. In this study, the reverse technology was surveyed, and the MEP facility management based on 3D image scanning was analyzed. Based on the results, a method of 3D image scan-based MEP facility management was proposed.

Objectives: Herbal dispensaries can be installed separately from medical institutions. This study was done to suggest directions of regulation on management of externally installed herbal dispensaries. Methods: In this study, we visited and investrigated 7 representative herbal dispensaries to understand current status of herbal dispensaries. After comprehending current domestic regulations on herbal dispensaries, we referred "Management Practice on Dispensary Facility of Traditional Chinese Medicine in Medical Institution", "Enforcement Rule of Decree on Institution Standard of Manufacturing and Importation for Drugs, etc." and "Enforcement Rule of Food Sanitation Act" to suggest improved regulations for herbal dispensaries. Results: We suggested reasonable regulations for facility standards including location of building, dispensary room, water supply facility, lavatory and storage facility, etc.. Conclusions: We hope that results of this study could be baseline data for developing regulations on facility standards of herbal dispensaries.

This paper describes the instructional flexible manufacturing system(FMS) laboratory facility at Virginia Polytechnic Institute(VPI) which is directed at problems and issues in the design, implementation and control of computer integrated manufacturing systems. It begins with a configuration and an operational description of FMS laboratory facilities. Next, relevant curricula in manufacturing systems design and control, which can use the FMS laboratory for instructional purpose, are introduced, A computer simulation can be used as an excellent tool for analysis prior to implementation of FMS as well as an on-going improvement tool. A brief survey of simulation languages is lastly included.

This article deals with stochastic reliability systems that include a repair facility and unreliable machines: the main facility of working and an auxiliary facility of "super-reserve" machines. The number of super-reserve machines are random number with a arbitrarily distribution and working machines break down exponentially. Defective machines line up for repair, whose durations are arbitrarily distributed. Refurbished machines return to the main facility. If the main facility is restored to its original quantity, the repair facility leaves on routine maintenance until all of super-reserve machines are exhausted. Then, the busy period is regenerated. The whole system also falls into the category of closed queues, with more options than those of basic models. The techniques include two-variate Markov and semi-regenerative processes, and a duality principle, to find the probability distribution of the number of intact machines. Explicit formulas obtained demonstrate a relatively effortless use of functionals of the main stochastic characteristics (such as expenses due to repair, maintenance, waiting, and rewards for higher reliability) and optimization of their objective function. Applications include computer networking, human resources, and manufacturing processes.

Facility layout problems (FLP) are usually treated as design problems. Lack of systematic and objective tools to compare design alternatives results in decision-making to be dominated by the experiences or preferences of designers or managers. To increase objectivity and effectiveness of decision-making in facility layout selections, a decision support model is necessary. We proposed a decision model, which regards the FLP as a multi-attribute decision making (MADM) problem. We identify sets of attributes crucial to layout selections, quantitative indices for attributes, and methods of ranking alternatives. For a requested facility layout design, many alternatives could be developed. The enormous alternatives, various attributes, and comparison of assigned qualitative values to each attribute, form a complicated decision problem. To treat facility layout selection problems as a MADM problem, we used the linear assignment method to rank before selecting those high ranks as candidates. We modelled the application of the Nemawashi process to simulate the group decision-making procedure and help efficiently achieve agreement. The electronics manufacturing service (EMS) industry has frequent and costly facility layout modifications. Our models are helpful to them. We use an electronics manufacturing service company to illustrate the decision-making process of our models.
