Quality management is very important to ensure competitiveness through good quality products. It is performed in all fields of manufacturing. While small and medium-sized manufacturing enterprises have introduced quality management systems for systematic quality control, the effectiveness of such systems has been very low. To overcome this problem, it is necessary to develop and introduce a quality management system that can reflect uality work characteristics of individual SMMEs and support quality work on a company-wide basis. This study constructed a quality management platform for all SMMEs by first gathering common functions essential to perform quality work and then created a customized quality management system for each company by adding optional functions reflecting characteristics and requirements of the individual company. The quality management platform is designed in detail through a series of processes such as deriving functions that users want, redefining them, organizing the information flow, and designing the DB and user interface. It is structured in three steps involving DB layer, functional layer, and service layer. Its effectiveness was demonstrated by constructing and operating the customized quality management system applied to actual companies.

The remanufacturing system is a series of industrial process in which worn-out products are restored to like-new condition. The remanufacturing system is differ from the repair system not only process characteristics but also product characteristics. So, it is required to design another model for the remanufacturing system which is distinct from the repair system and also performance index is required for the remanufacturing system. Therefore, in this paper we suggest the availability model for remanufacturing system by using Markov Process. This model represents each of the states of the remanufacturing system. Also performance indexes of remanufacturing system are introduced. Performance indexes are consisting of part reuse frequency and time, part disposal frequency and time. As a result, we can have a choice and control the proper part and offer useful information during the remanufacturing by using these availability model and performance indexes.
