CALS체계에서는 한 제품의 주문으로부터 생산과 사후 관리에 이르는 전수명주기를 통합관리해야하므로 화상과 음성을 포함한 멀티미디어 정보를 교환할 수 있어야 한다. 더욱이 기존의 산업사회에서는 순차적 공정에 따른 생산방식을 적용해 왔으나, 향후 미래사회에서는 민첩한 지능형 가상기업만이 생산경쟁력을 갖출 수 있는 생산형태의 변화가 예상되어 경쟁력있는 기업모형의 변화가 뒤따를 것이며, 기업경쟁력의 우선순위는 한 품목의 생산에 소요되는 시간과 비용, 그리고 소비자의 성향에 맞는 우수한 품질이 고려된 동시공정 체제를 갖추는 것이 매우 중요한 과제로 대두될 것이다. 이러한 CALS의 성공적인 구현을 위한 기본적인 주요 요소기술은 기업업무처리 변화에 다른 업무공정의 표준화, 통합데이타베이스를 이용한 동시공정의 설계, 그리고 기업내.외의 모든 거래를 디지털 방식으로 송.수신하는 전자상거래로 대별할 수 있으며, 그중 동시공정은 기술적으로 매우 중요한 부분이라 할 수 있다. 이를 위해서는 기업내의 부서 상호간은 물론 원자재의 수급에 참여하거나 생산에 공동으로 참여하는 모든 기업들 간에 상호 정보교환이 동시에 발생할 수 있어야 하며, 이러한 다양한 정보공유자로부터 얻어지는 모든 자료를 통합관리하여 의사결정자가 신속하고 정확한 판단을 할수 있도록 지원체계를 만들어야한다. 본 연구는 이러한 CALS체계에서 동시공정 작업이 신속하게 성공적으로 수행될 수 있도록 분산된 정보들에 대한 신속한 의사결정을 지원하는 관리자에 대한 방안을 제시하고자 한다.

Shipbuilding production management is one of the most significant activities in productivity improvement. Shop-floor managers and production planners still do not have enough production information for shop-floor scheduling due to shortage of information sharing among them. In this research, main issues were derived from requirement analysis between production planning and shop-floor control to establish a software system architecture for ship production monitoring system(SPMS), which is developed with component based design(CBD). The proposed system's key functions cover from block shop assembly to quay outfitting stage to visualize production progress as well as to maximize production information sharing. The system will allow more reliable and accurate production information to permeate down to members of the workforce just in time.

This Study is to show the impact of IT capital stock accumulation on the total factor productivity in 9 industries during 1980 through 2000. We construct the If capital stock using input and output table provided by Bank of Korea (2000). Using sequence testing methodologies, we investigate the nonstationary characteristics of the relevant data and test the cointegration relationship between total factor productivity and IT capital stock. Over the past two decades, IT capital stock contributed between 0.19 to 0.07 percentage point per IT capital stock on total factor productivity. Our empirical results, therefore, do not support Solow's IT paradox in using the long period panel data case in Korea.

The purpose of this study is to investigate the perceived quality toward user performance and corporate performance in production information systems. For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 132 enterprises which have implemented production information systems, and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, production information quality and support service quality are confirmed to have a positive effect on user's satisfaction, however, I found no evidence of a statistically significant relationship between system quality and user's satisfaction. Second, all of three quality factors which are production information quality, system quality, and support service quality have positive influence on system usage. Third, user's satisfaction has positive influence on system usage, and both of user's satisfaction and system usage have positive influence on performance improvement. Based on these findings, this study suggested the implications, as well as limitations and further research directions.

Manufacturing Information System is a information system which supports the activities such as production planning, workflow management, work stage control. Manufacturing fields are showing new properties in today such as digital information, globalization, integration, to make sophisticated production. In this paper, we descibe major issues in current systems. Eventually, we propose major factors to adapt for new changes and BI systems to support manufacturing production information system based on the major factors.

Despite the recognition of the need for productivity information and its importance, the feedback of productivity information is not well-established in the construction industry. Effective use of productivity information is required to improve the reliability of construction planning. However, in many cases, on-site productivity information is hardly management effectively, but rather it relies on the experience and/or intuition of project participants. Based on the literature review and expert interviews, the authors recognized that one of the possible solutions is to develop a systematic approach in dealing with productivity information of the construction job-sites. It is required that the new system should not be burdensome to users, purpose-oriented information management, easy-to follow information structure, real-time information feedback, and productivity-related factor recognition. Based on the preliminary investigations, this study proposed a framework for a novel system that facilitate the effective management of construction productivity information. This system has utilized Sketchup software which has good user accessibility by minimizing additional data input and related workload. The proposed system has been designed to input, process, and output the pertinent information through a four-stage process: preparation, input, processing, and output. The inputted construction information is classified into Task Breakdown Structure (TBS) and Material Breakdown Structure (MBS), which are constructed by referring to the contents of the standard specification of building construction, and converted into productivity information. In addition, the converted information is also graphically visualized on the screen, allowing the users to use the productivity information from the job-site. The productivity information management system proposed in this study has been pilot-tested in terms of practical applicability and information availability in the real construction project. Very positive results have been obtained from the usability and the applicability of the system and benefits are expected from the validity test of the system. If the proposed system is used in the planning stage in the construction, the productivity information and the continuous information is accumulated, the expected effectiveness of this study would be conceivably further enhanced.

The purpose of this study is to investigate the status of manufacturing information system (MIS) which has been introduced to enhance the manufacturing competitiveness in Korea and to enable statistical comparison of whether there are significant differences in implementing manufacturing information system between large companies and small and medium enterprises (SMEs). The result of the empirical test of 105 manufacturing companies in Korea showed that the utilization and satisfaction of MIS in large companies are significantly greater than those in SMEs.
