Spare part management is very important to products that have large number of parts and long lifecycle such as automobile and aircraft. Supply chain must support immediate procurement for repair. However, it is not easy to handle spare parts efficiently due to huge stock keeping units. Qualified forecasting is the basis for the supply chain to achieve the goal. In this paper, we propose an agent based modeling approach that can deal with various factors simultaneously without mathematical modeling. Simulation results show that the proposed method is reasonable to describe demand generation process, and consequently, to forecast demand of spare parts in long-term perspective.

IR camera has been used widely for the temperature measurement and fault detection of the moving bodies and rotating bodies. The high-speed performance of the IR camera and a reliable thermal analysis method are required for the condition monitoring of the railway vehicle running at high speed. The effective fault detection method using a thermal image analysis could make a real time monitoring of the high speed train possible. Therefore the investigation of the performance of the thermal image analysis method was performed to find the effective thermal image data analysis method. The results suggested that the comparison of the characteristics of the temperatures obtained at different conditions and a continuous temperature subtraction method could be used as a useful analysis method for detecting abnormal temperature condition and histogram equalization could also help to enhance the fault detectability by increasing the contrast of the thermal image

In case of many products placed on the production line in automobile production, some line is personnel visually identifiable, such as CCTV, while the rest areas are not identifiable. However, because the position of accidents is not scheduled and every accidents should be analyzed at every point, every accidents is not easy because you need to an immediate response. The record cause of the accident is difficult to understand, not until after the accident for the accident cause analysis of fragmentary and mechanical information so that future accidents have difficulty measures be established. To prevent this, the car accident occurred in the manufacturing plant personnel to deploy and monitor in every area of enterprise is too burdensome labor costs too high. In this study, automated car production plant and load transfer system crash, accident collision and records are available for real-time wireless transmission, the administrator determines that situation can be immediately developed the electronic mono rail system(EMS).

The national Logistics Information system has been rapidly developed on account of the dramatic improvements in the military’s logistics support system and supply support system, making a transition from manual work system to computerized work system. Supply level, however, does not reflect these changes in the overall logistics environment and still retains the state it was in the 1970s. This research uses the accumulated data from the equipment․maintenance information system developed in the year 2009 to analyze RWT( Requisition Wait Time) and CWT (Customer Wait Time). The analysis estimated the realistic transportation and ordering time and led to the conclusion that the differentiated ASL operation system that considers demand level should be adopted instead of the uniform ASL employment system.

Burdock (Arctium sp.) is known as a nutraceutical vegetable, especially in Japanese and Korean cuisine. While burdock plants are generally harvested for their tap roots, different parts of the plant are consumed as food or used as traditional medicines. This study investigated the physicochemical properties of the leaves, stems, roots, and peeled roots of the burdock plant based on their pH, soluble solid content, titratable acidity, color values, and mineral content. The pH differed significantly among the different plant parts, with the highest value in the leaves and the lowest in the stems. However, for the soluble solid content, the leaves had the lowest, while the peeled roots had the highest. The titratable acidity of the stems was significantly lower than that of the leaves, roots, and peeled roots. As regards the color values, the lightness value was highest for the stems, while the roots showed the highest redness value, followed by the peeled roots, and the leaves had the highest yellowness value. The leaves and stems contained almost three times more potassium than the roots and peeled roots. Thus, the higher content of different minerals in the leaves and stems of the burdock plant shows that these plant parts could be used as potential sources of dietary minerals.
