The competitiveness of the manufacturing company is evaluated in terms of line productivity, quality cost, inventory level, logistics efficiency, and so on. The productivity is defined by the number of products divided by the number of workers within the given operation time. Increasing the productivity is not easy to man-operated situation in the line, since it heavily depends on the standard time of the workers. This paper deals with the productivity of the Back Light Unit assembler for TFT-LCD, and proposes the methodology of investigating the optimal process by simulation of Arena.

  Exact solutions for practical-size problems in job shop will be highly inefficient. Scheduling heuristics, therefore, are typically found in the literature. If we consider real-life situations such as machine breakdowns, the existing scheduling methods

Maintaining superior productivity and quality in LCD requires enhancing competitiveness of partners or suppliers, such as PBA, BLU, or Mold Frame. BLU is one of the most important parts in LCD, however manufacturing environment is tedious and labor intensive. In this paper, we propose simulation modeling for BLU production process. We also investigate optimal process in terms of line balancing and conveyor characteristics.

The purpose of carrier tracking and tracing is to achieve more information over shipments via carrying in mobile business. At multimodes, especially consignor wants to be aware of the exact situation and position of goods. As an innovative business model, we present CGPS(Carrier Global Positioning System) scheme using LEO(Low Earth Orbital) satellite. The LEO collects the data periodically and sends to the web server, and eventually customer's PC or PDA. This provides shipping company or freight forwarder with more robust information such as door status, container inside condition, etc.

Among many logistics technologies, primary area should be investigated in terms of long term periods. Therefore private company and public sector can visualize approaches to their corresponding industry. In this paper, we introduce vision and roadmap for
