최근 많은 기업에서 전사적 자원관리 시스템의 보급이 활발히 이루어지고는 있으나, 해당 시스템의 기초데이터라 할 수 있는 생산실적의 수집에 있어 많은 문제점이 발생하고 있다. 생산실적의 늦은 수집은 효율적 기업운영에 치명적이라 할 수 있으며, 이러한 이유로 실시간 생산실적을 수집하는 POP시스템의 도입이 해결방안으로 널리 구축 운용되고 있다. POP시스템의 구축 및 운용에 있어 가장 중요한 사항은 정확한 생산실적의 실시간 수집이라 할 수 있으나, 적지 않은 구축 기업들에서 몇 가지 요인들로 인한 신뢰할 수 없는 데이터의 수집으로 기업 경쟁력을 떨어뜨리는 결과를 보여주고 있다. 본 연구에서는 이러한 요인들을 분석하고 신뢰성을 향상시킬 수 있는 방안을 제시하며, 실제로 적용된 사례를 소개하고자 한다.

A framework for knowledge management system has been explored which enables the semantic search of knowledge on the web. Knowledge representation by RDF and RDF schema enables machine cognition of knowledge documents. Dublin core was adopted for structured metadata representation. Thereby, it enables the CBR and rule based reasoning for intelligent knowledge retrieval. Grafting of the WFMS technique unto the KMS facilitates the effective utilization of process knowledge and creation of new knowledge.

A URC, which is a Ubiquitous Robot Companion, provides services to users in ubiquitous computing environments and has advantage of simplifying robot's hardware and software by distributing the complicated functionality of robots to other system. In this paper, we propose SOWL, which is a software architecture for URC robots and a mixed word of SOMAR and CAWL. SOWL keeps the advantages of URC and it also has the loosely-coupled characteristics. Moreover it makes it easy to develop of URC robot software. The proposed architecture is composed of 4 layers: device software, robot software, robot application, and end user layer. Developers of the each layer is able to build software suitable for their requirements by combining software modules in the lower layer. SOWL consists of SOMAR and CAWL engine. SOMAR, which is a middleware for the execution of device software and robot software, is based on service-oriented architecture(SOA) for robot software. CAWL engine is a system to process CAWL which is a context-aware workflow language. SOWL is able to provide a layered architecture for the execution of a robot software. It also makes it possible for developers of the each layer to build module-based robot software.
