The material handling equipment selection, that is a key task in the material handling system design, is a complex, difficult task, and requires a massive technical knowledge and systematic analysis. It is invaluable to justify the selected equipment model by the performance evaluation before its actual implementation. This paper presents an intelligent knowledge-based expert system called "IMESE" created by authors, for the selection and evaluation of material handling equipment model suitable for movement and storage of materials in a manufacturing facility. The IMESE is consisted of four modules: a knowledge base to select an appropriate equipment type, a multiple criteria decision making procedure to choose the most favorable commercial model of the selected equipment type, a database to store the list of commercial models of equipment types with their specifications, and simulators to evaluate the performance of the equipment model. The whole process of IMESE is executed under VP-Expert expert system environment.vironment.

A novel methodology to evaluate remote dismantling equipment for a reactor pressure vessel (RPV) in a decommissioning project is presented in this paper. The remote dismantling equipment, mainly composed of cutting tools and positioning equipment, is absolutely required to cut and handle highly radioactive and large components in nuclear power plants (NPPs); this equipment has a great effect on the overall success of the decommissioning project. Conventional evaluation methods have only focused on cutting technologies or positioning equipment, although remote dismantling equipment cannot achieve its goal without organic interaction between the cutting tools and the positioning equipment. In this paper, the cutting tools and the positioning equipment are evaluated by performance parameters according to their original characteristics, the relationship between the two systems, and common factors. Finally, the remote dismantling equipment used in recent decommissioning projects has been evaluated based on the proposed methodology. The results of this paper are expected to be useful for future decommissioning projects.

According to Korea Standard Association (KSA-0013) storage facilities are so broadly defined that one cannot easily understand the area and contents of storage facilities. Generally speaking warehouse represents storage facilities which links two nodes in various logistics activities, and storage facilities should contain other facilities like mechanization equipment, automation equipment, information equipment, etc. This study is to show the direction of the evaluation method on the effectiveness of standardized storage facilities. The storage facilities treated in this research are not only storage facilities like warehouse but also storage supporting facilities like mechanization equipment, automation equipment, information equipment, etc. The method for evaluating the effectiveness of standardized storage facilities is to developing some measure of effectiveness (MOE) which represents the entire standardized effectiveness of storage related facilities. This study has originality in that the method for evaluation of standardized storage facilities has not been developed up to now.

본 연구에서는 습식 방법으로 진행 되는 BGA 현상 공정에 있어 기존의 수평 장비를 대체하여 수직 장비를 개발하였다. 지그를 이용하여 기판을 수직 방향으로 고정한 후 습식 공정을 진행함으로써 기존 수평 장비의 단점인 롤러와 기판 표면 회로 패턴의 충돌로 인한 회로 패턴 손상 문제를 원천적으로 제거하고자 하였다. 개발된 수직 장비의 공정 특성을 수평 장비와 비교 평가 하기 위하여 유니포미터 측정, 회로 패턴 손상 평가 및 불량 평가의 실험을 수행하였다. 평가 결과 수직 장비의 유니포미티 특성은 수평 장비와 동일한 수준이며 중력 방향의 액흐름에 대한 공정 특성 영향은 미미한 것으로 확인 되었다. 또한, 수평 장비 대비 $3{\sim}4{\mu}m$ 더 미세한 회로 패턴에 대해여 손상 없이 공정을 진행 할 수 있음을 확인 할 수 있었다.

In a previous study, the suitability for use of inspection equipment was evaluated at temperatures outside the quality assurance range. The quality assurance operating temperature of the safeguards equipment is 0~+40℃, and previous studies have confirmed the performance of the safeguards equipment for temperatures ranging from -40~+70℃. The scintillator-based verification equipment showed a shift in the centroid channel and a change in the count rate in all temperature ranges, and the semiconductor-based safeguards equipment generated Leakage Current and equipment failure. In this study, a retrofit was performed applying a vacuum housing to the safeguards equipment (Inspector-2000-based inspection equipment), and performance evaluation was performed at a low temperature and snowy site, and it was confirmed that the same performance was observed as the measurement results at room temperature.

The cost needed to managing equipment is constantly increasing because of increase of power equipment. The regulations such as PAS 55 and ISO 55000 were enacted to manage equipment assets. The advanced management methods such as real-time monitoring, condition evaluation, and health indices are avalable in generation system, transmission system, and substation transformers. However, These methods can not be applied to distribution equipment because of a lot of equipment. Therefore reliability assessment is very important in case of distribution equipment. In this paper, failure rates are extracted considering characteristics of regions, and which are the essential factors to reliability evaluation.

To propose an ergonomic layout on the bridge, this study conducted a usability evaluation on the on-bridge navigational equipment of a college training ship that is in use at present. Through the usability evaluation on the training ship navigators, the possibility of operational errors with navigational equipment, the possibility of readout errors with display devices and even the effect of navigational equipment on navigation were evaluated beyond the scope of existing layouts, which adopt only the importance and usage frequency of navigational equipment. By taking ergonomic variables into consideration, this study suggested an optimized layout for on-bridge navigational equipment using a mathematical programming model.

This study focuses on the classification of fire equipments for certification based on the risk evaluation. In general, known statistics on fire equipment-related accidents needs to be used for risk evaluation. When statistics is not available, however, expected frequency and severity of accident for individual equipment can be taken into account in evaluating the related risks. Based on the level of inherent risks, each equipment is then classified into three categories for certification. For equipments that risk evaluation is not possible, characteristics of those products such as reliability are considered for classification. Once classified, each equipment is assigned an appropriate certification module.
