Recently groupware has been popularly adopted by corperations to gain competitive position. In Korea, one of major function of those systems is the Electronic Authorizing System because korean firms have authorizing system but western firms do not. Thus researches on EAS has never been produced before. The purpose of this research is to build the research framework for productivity measurement of EAS. The research model of EAS has investigated three dimensions including Business process, ease of system use and media richness to meet this end. Based on this model, author conducted case study with mailing questionaires. The result of research shows that the factors of the business process and ease of system use raise the productivity but the factor of electronic media a little decreases it. Also author finds business process affects the productivity in three ways such as changing layout of papers for authorizing, changing business process and removing waiting time for authorization. Finally, based on the result of research, this paper adds some recommendations for EAS builder.

Even though the woollen-yarn-making process as a whole has received much attention from customers in recent years, but yet there exist many problems to improve quality, productivity, and working environment in a small-medium woollen-yarn manufacture. To achieve the aim for improvement of quality and productivity, we have performed a period of education and training for workers. And thus this paper reports a study carried out them in the company located in near Pusan. Also, this paper describes a study how has a small-medium company introduced the education for the workers by authors. Among the possible outcome of this study is that the company does encounter considerable difficulties in the education and training. But to improve the quality and productivity, we assert that the company has to overcome these courses. We all recognize that the employer has been prepared for education and training to improve the employees' working conditions for a long time.

Up-to-date manufacturing companies have faced a market-driven environment of pull production order. There should be a difference in operating manufacturing resources according to the type, quantity, and delivery time of manufactured products, because the process situation in pull production is changed by customer orders. And it should be taken into account from the stage of preparing for production such as process design and the placement and utilization of manufacturing resources. However, the feasibility of production plans is limited because most of small manufacturing businesses make production/supply plan of the parts and products assuming that equipment abilities in scheduling is sufficient without managing process standard information systemically. In this study, a discrete event simulation system based on BOM (bill of material), that is F-OPIS (online productivity innovation system), is introduced and a case study on application of the system leading to improving productivities is presented. F-OPIS deals with a decision-problem on production management and it is specialized for small-and- medium sized manufacturing companies. The target company of this case study is a typical small-and-medium sized manufacturing company in Korea, that produces various machined parts. The target company adopts make-to-stock production management to prevent tardy delivery because of fluctuations in demand. Therefore, it is required to apply an efficient inventory control solution for improving productivities. In this paper, based on the constraints of working capacity of manufacturing resources, the bottleneck process is analyzed as production conditions are changed. Consequently, an improvement plan is proposed, that eventually enhances overall utilization rates of resources in the bottleneck process and reduces overall production lead-time and inventory level.

A production system in domestic shoes companies has difficulty in achieving automation and information because of insufficiency of flexibility and standardization. Particularly small and medium sized shoes companies producing by OEM have tendency to chase the given production schedule blindly without considering major factors that may affect the production. Therefore, the production schedules or the process conditions can not be optimally set and are extemporized by the experience in the past. These behaviors cause low productivity and financial loss. To maximize efficiency and productivity of the shoe-making process, we develop a simulation model based on a production system in small and medium sized shoes companies. The model has been developed using ARENA which has been demonstrated to be a powerful tool to simulate various manufacturing systems. Using the simulation model, we find out several problems for the production process, and then suggest several alternatives to improve the system.
