Vendors and consultants struggle to draw attention to their proven experience in discrete CIM in order to convince process manufacturers to adopt CIM technology. The analogy works very well at the periphery where an invoice is an invoice, but disintegrates at the core where modeling of the manufacturing "process" is required. Until recently, it has not been possible to completely and rigorously model entire process plants in real-time, and this missing core element has been called the "CIM GAP" With the recent introduction of the concurrent resolution $^{sm}$ kernel, the CIM GAP now is being closed in the process industries.ntroduction of the concurrent resolution $^{sm}$ kernel, the CIM GAP now is being closed in the process industries.

Two key data areas of the integrated production database in computer-integrated manufacturing (CIM) systems are the product structure in the forms of bills of material(BOM) and the process structure in the forms of routings. The great majority of existing information systems regard the BOM and routing as two separate data entities, possibly with some degree of cross-referencing. This paper proposes new information structure called the bills of material and routings(BMR) that logically integrates the BOM and routings for the CIM systems in ship production. The characteristics of ship production are described as: 1) make-to-order production type, 2) combined manufacturing principles (workshop production and construction site production), 3) significant overlapping of design, planning and manufacturing, 4) very long order throughput time, 5) complex product structure and production process. The proposed BMR systematically manages ail parts and operations data needed ship production considering characteristics of ship production. Also, the BMR situated on the integrated production database more efficiently supports interface between engineering and production functions, and integrates a wide variety of functions within production such as production planning, process planning, operation scheduling, material planning, costing etc., and simplifies information flow between sub-systems in CIM systems.

AC PDP has disadvantages that power consumption and sustain voltage are high. An energy recovery circuit for AC PDPs with reduced sustain voltage was proposed to solve these disadvantages. However, the circuit has disadvantage that the switching elements are performed hard switching at the start point of discharge and sustaining region. The reason is that the panel voltage is lower than sustain voltage at that point. In this paper, we propose the improved driving method that switching devices are operated with ZVS by using CIM(Current Infection Method) also at that point. CIM region is designed by theoretical circuit analysis. Finally, the validity of the proposed driving method is verified by the simulations and experimentation.

This paper described finite element analysis (FEA) for fabrication processes of PZT perform using ceramic injection molding (CIM). The viscosity and the PVT characteristics of the manufactured PZT feedstock were measured. The filling patterns, pressure and temperature distributions of the preform were analyzed with TIMON 3D packages during CIM process. The geometrical variables such as gate type, location, and base thickness of the preform were considered. Also the fabrication conditions of the preform were optimized during the entire CIM process. Based on the simulated results, the various good perform was easily fabricated with the CIM process.

Computer Integrated Manufacturing (CIM) is undoubtedly one of the most influential concepts to have been introduced into the manufacturing world in recent times. The successful CIM application is greatly depended on the way of the approach to given manufacturing environments. This paper suggests a new approach in building CIM systems and also discusses roles of a open cell controller for this purpose.

Some concepts and methods for information system as a part of CIM system in ship production are proposed in this paper. The characteristics and problems focused on product design and production planning and control are analyzed. A conceptual framework for CIM in ship production is presented, which is focused on a product model for information system. A methodology for the practical use of information for each managerial class is also presented.

The objective of cell operation in CIM is to maximize system efficiency, not the cell itself. We introduce a cell operation scheme that pursues the direction. For specific cases, work center and AS/RS are closely investigated. Structures of their operation mechanism and methods of job scheduling are introduced along with an expert system developed for the scheme. The cell operation softwares developed are now under test at K.U.FMS, a model CIM plant.

The purpose of this paper is to analysis of some factors of CIM systems which influence on the quality in our business. Through the influential factors from analysing preliminary inquiry, we surveyed the effects of CIM systems. In conclusion, we have proved that there are many differences in view of quality between the business adopted this system and the other not adopted this.

An advanced form of the Partitioned Feature-based Classifier with Expertise Table(PFC-ET) is proposed in this paper. As is the case with the PFC-ET, the proposed classifier model, called Classifier Integration Model(CIM), does not use the entire feature vectors extracted from the original data in a concatenated form to classify each datum, but rather uses groups of features related to each feature vector separately. The proposed CIM utilizes a proportion of selected cluster members instead of the expertise table in PFC-ET to minimize the error in confusion table. The proposed CIM is applied to the classification problem on two data sets, Caltech data set and collected terrain data sets. When compared with PFC model and PFC-ET model. the proposed CIM shows improvements in terms of classification accuracy and post processing efforts.

In the development of MDMS(Meter Data Management System) based on CIM(Common Information Model), which is international standard in information model and data exchange on power system, the two focused issues are the effective management of data collected in a shorter time period and the way to integrate services supporting legacy system to use the AMI(AMI, Advanced Metering Infrastructure) data. In this paper, we propose MDMS implementation methods and functions in AMI environment which are differ from existing AMR system environments in that the methods support bi-directional service infrastructure. The proposed MDMS in this paper has two unique features, one is the secure of interoperability by utilizing the CIM and ESB, the other is the improvement of field application by implementing system module based on components. On an implementation of smart grid, the result of proposed methods is expected to contribute to the efficient development and operation of CIM-based power system.
