Mercedes-Benz United States International (MBUSI) built a manufacturing facility for the production of the new M-Class All Activity Vehicle (AAV). This plant consists of three large sequential shops: the Body Shop, the Paint Shop, and the Assembly Shop. When the plant reaches full production, 270 vehicles will be produced each day by two shifts. A finished vehicle is intended to leave the end of the assembly line every 3.6 minutes. The main objective of this study is to simulate the design and operational policies of the AAV assembly facility and to verify that the daily throughput requirements can be met. The simulation study also answered the following questions: What is the maximum throughput (capacity) of the facility? What is the daily distribution of throughput? Does the current design produce the required throughput of 270 cars per day? How do the buffers behave in terms of quantity fluctuations? What are the possible bottlenecks to the desired throughput? This paper provides a description of the integrated simulation model to analyze the capability of the production facilities at MBUSI. This paper includes the inputs used for the development of each of the three individual models: the Body Shop, the Paint Shop, and the Assembly Shop. Additionally, it includes descriptions of the model features and the assumptions that were made.

Emission characteristics of gaseous odor compounds emitted from the charcoal manufacturing process were investigated, and evaluated the odor removal efficiency of odor control devices. It was found that the measured odor dilution ratio of emission gases ranged from 10,000 to 44,814, which exceed largely the emission standard in the stack. Methylmercaptan, trimethylamine, hydrogen sulfide, acetaldehyde were turned out as major odor compounds of the charcoal manufacturing process. It was revealed that the odor removal ratio of odor control devices were very low due to the its improper maintenance and wrong design.

REMICON(Ready Mixed Concrete), the most essential material of construction work, is produced from facility called "Batcher plant." In order to produce Remicon, Batcher Plant needs to be supplied with basic raw material such as ballast, sand, cement, admixture and water. In remicon industry, overland transport vehicles are used during the whole manufacturing process from producing to infilling at the construction site. Thus, the transportation cost sums up be to 20 percent of whole manufacturing cost and transport capacity and distance travelled have direct and major effect on manufacturing costs. This paper suggests a method to find optimal location of batcher plant using modified Steiner point, suggesting the most effective and flexible connection through among construction site, aggregate, cement and remicon producing plant. This paper also proposes reducing of transport cost at maximum 60% by calculation through optimized plant location. The modified Steiner point theory proposed in this paper also can be applied to optimal location of a $2^{ry}$ substation or MCC panel for minimizing of power loss, voltage drop, line distance and etc.

This study analyzed the current status of registered patents related to food tech in Korea and Japan. Using the patent information search services of Korean and Japanese Patent Offices, patents registered during the past 10 years from January 1, 2005 to December 31, 2015 were searched with the following key words/phrases: "food or meal or diet" and "program or information system". A total of 669 patents (539 for Korea and 130 for Japan) were finally selected and analyzed. Based on Porter's value chain theory, the patents were categorized into three dimensions related to "manufacturing/processing/distribution", "sales & marketing", and "consumer support". The results showed that in Korea, 41.7% of the total patents were related to sales & marketing followed by consumer support (37.3%) and manufacturing/processing/distribution (21.0%). In Japan, patents related to consumer support accounted for 56.2% followed by manufacturing/processing/distribution (32.3%), and sales & marketing (11.5%). In the area of manufacturing/processing/distribution, "food quality management system" in Korea, and "food manufacturing and processing management system" and "food safety control and hazard analysis system" in Japan tended to show a significantly higher proportion of patents registered (p<.05). Under sales & marketing, patents in the categories of "food purchase and delivery service system" in Korea and "restaurant information sharing system" in Japan tended to be more frequently registered (p<.05). Finally, in the area of consumer support, "kitchen facility and cooking device control system" in Korea and "menu and nutrition management system" in Japan tended to account for a significantly higher proportion of patents registered (p<.001). The results are expected to provide useful insights into the development of new patents and markets for food tech in the future.

Semiconductor manufacturing has suffered from the complex process behavior of the technology oriented control in the production line. While the technological processes are in charge of the quality and the yield of the product, the operational management is also critical for the productivity of the manufacturing line. The fabrication line in the semiconductor manufacturing is considered as the most complex part because of various kinds of the equipment, re-entrant process routing and various product devices. The efficiency and the productivity of the fabrication line may give a significant impact on the subsequent processes such as the probe line, the assembly line and final test line. In the management of the re-entrant process such as semiconductor fabrication, it is important to keep balanced fabrication line. The Performance measures in the fabrication line are throughput, cycle time, inventory, shortage, etc. In the fabrication, throughput and cycle time are the conflicting performance measures. It is very difficult to achieve two conflicting goal simultaneously in the manufacturing line. The capacity of equipment is important factor in the production planning and scheduling. The production planning consideration of capacity can make the scheduling more realistic. In this paper, an input and scheduling rule are to achieve the balanced operation in semiconductor fabrication line through equipment capacity and workload are proposed and evaluated. New backward projection and scheduling rule consideration of facility capacity are suggested. Scheduling wafers on the appropriate facilities are controlled by available capacity, which are determined by the workload in terms of the meet the production target.

The purpose of this research is to investigate the actual conditions of the manufacturer's design processes. Questionnaires were sent out, and 57 interviews were used as research methods including designers, programmers, and merchandisers working for a knit manufacturer in Seoul, followed by a frequency analysis using SPSS 12.0. The results are as follows: knitted fabric goods were the top choices in casual wear. Brand image depended on 'elegance', 'modernity', and 'romanticism', among other lifestyle pursuits. The distribution ratio of the 'basic' and the 'trendy' knit was at 3:7 or 7:3, while the ratio of 6:4 or 4:6 was more common. Knit structure was proven to be the most important factor in the changes in designs. Style and yam ranked second and third, respectively. In addition, details (embroidery and beading), color, pattern, and processing were among the other factors, in order of importance. Based on the difficulty in designing and manufacturing knitted fabric goods, 'manufacturing cost:' 'lack of a manufacturing facility for small production,' and 'limited delivery time' were among the reasons cited in the questionnaire. These results appeared to have been caused by small-scale manufacturers or small-scale manufacturing facilities that made small volume production difficult. The results of the interviews on knitted fabrics that were most frequently used and with the highest sales volumes showed that plain, lace, links & links, miss, and 1:1 rib were ranked accordingly for S/S use, while jacquard, cable, 1:1 rib, links & links, milano, plain, and half cardigan were ranked accordingly for F/W use.

In this paper, in order to improve production processing for small and medium-sized precision processing companies, we apply a manufacturing execution system to existing process methods and integrate precision processing data to strengthen process management within the company, increase facility operation efficiency, and realize a reduction in defect rates. The differences in productivity improvement and cost reduction rates were compared and analyzed. As a result, production productivity improved by 7.0% and product defect rate improved by 0.1% point due to the introduction of the manufacturing execution system. It was confirmed that manufacturing cost reduction improved by 10.0% and delivery compliance rate improved by 1.1%. If additional smart factory technology is applied based on the manufacturing execution system proposed in this study in the future, sales and profits in the processing industry are expected to increase due to an increase in the PQCD index.

Environmental awareness is rising worldwide. however, cement manufacturing facilities use recycled resources to improve raw material and fuel substitution rates, contributing to environmental issues such as waste disposal. The emission of sulfur oxides (SOx), an air pollutant, has been regulated by limestone as raw material in cement manufacturing. However, the impact of increasing use of recycled resources on future facility processes and environmental changes is unclear. Therefore, the cement manufacturing facilities require desulfurization-related technologies and research. In this study, we investigated the applicability of desulfurization technology to cement manufacturing facilities and demonstrated various approaches to applying this technology using byproducts generated in cement manufacturing.
