  • This study was carried out to estimate carbon footprint and to establish of LCA of garlic production system. We have case study in cultivate garlic 1 kg calculate in carbon footprint. LCA carried out to estimate carbon footprint and to establish of LCI (life cycle inventory) database of garlic production system. The data is from Research of Farmer's income in 2010 (RDA, 2011), and used Pass (5.0.0) program. The value of fertilizer, amount of pesticide input were shown the environmental effect and direct emission. Carbon footprint in agriculture guarantees the choice right the consumer to choose the lower carbon goods. Its can make to strengthen of agriculture and food industry's reduction effort of $CO_2$. Nowadays consumer requests food's safety and environment friendly process. Carbon footprint also needs consumer's relief and incentives.

  • This study was carried out to estimate carbon footprint and to establish of LCA of cherry-tomato production system. I have case study in cultivate cherry tomato (1 kg) calculate in carbon foot print. LCA carried out to estimate carbon foot print and to establish of LCI (life cycle inventory) database of cherry tomato production system. The data is from Research of Farmer's income in 2007 (RDA, 2008), and used Pass (4.1.3) program. The value of fertilizer, amount of pesticide input were show the environmental effect and direct emission. Carbon foot printing in agriculture guarantee the choice right th consumer th choose the row carbon goods. Its can make to strengthen of agriculture and food industry's reduction effort of $CO_2$. Nowadays consumer request food's safety and environment friendly process. Carbon foot printing needs consumer's relief and incentives.

  • Highly standardized products are suitable for automated purchasing using electronic commerce technology, where the price becomes the most important factor. Suppliers can change the prices dynamically based on the inventory level and market situation in order to maximize the sales and profit. In the virtual marketplace where multiple customers purchase multiple standardized products from multiple suppliers repetitively, customers can purchase the required amount of each item as a dynamic bidding by allocating purchase orders to the suppliers based on the current price. Customers need a method to quickly determine the optimal allocation of orders to the suppliers using the dynamically changing data to minimize the total cost. We present a LP model which minimizes the sum of the total price plus transportation cost for this problem. Simulation results using random data show meaningful reduction of the total cost.

  • This paper examined the supply chain management partnerships factors and business performance in textile industry. To build a global network, we should consider the following critical factors such as lead-time reduction, information sharing, and inventory management. The purpose of this study is to focus on QR (Quick Response) of SCM in textile industries to clarify which of the SCM factors contribute to business performance for the SCM firms. Based on the analysis of eighth-six cases, the following results were found. First, partnerships factors of supply chain management have a positively significant influence on responsiveness of supply chain management. Second, partnerships factors of supply chain management have a positively significant influence on flexibility of supply chain management. This study suggests that partnerships are main factors for the business performance. Especially, our empirical evidence shows that capacity of firms practicing SCM, information techniques, and partnerships make the firms' business performance more responsive and flexible.

  • The distribution center location and routing problem involves interdependent decisions among facility, transportation, and inventory decisions. The design of distribution system affects the customers' purchase decision by sets the level of customer service to be offered. Thus the lower product availability may cause a loss of demand as falls off the customers' purchase intention, and this is related to the firm's profit reduction. This study considers the product availability of the distribution centers as the measure of the demand level change of the demand points, and represents relation between customer service and demand level with linear demand function. And this study represents the distribution center location and routing to demand point in order to maximize the total profit that considers the products' sales revenue by customer service, the production cost and the distribution system related costs.

  • This paper deals with the productivity increment through construction of lean production system for automobile factory in China. This lean production system has been progressed according to 5 steps. Step 1 is the work preparation. Step 2 is the process design. Step 3 is the establishment of method to count production quantity. Step 4 is the establishment of measuring method for input and output. Finally, step 5 is the construction of flexible production system able to adapt for environment change. This lean production system is expected to obtain the productivity increment by 50% for plastic plant and reduction by 50% in inventory quantity.

  • This paper deals with the application and effects of MES for H automobile plant in China. There existed the production planning and the different work order in PL painting plant, but we can simultaneously prepare the painting parts and parts delivery and assembly according to painting color by introducing MES. We can respond the change of production planning and operate integratively the PL painting, parts storage and parts delivery and then we can results in reasonable logistics. We obtained the exact production information, correct work order, precise delivery order. We obtained not only the improvement of logistics but also the reduction of inventory.

  • An EOQ-like inventory model for a manufacturing process is studied. The system is assumed to deteriorate during the production process. The results are either the production of a number of defective items, or the breakdown of the production machine. The optimal production lot size is derived. The model is extended to the case in which the probabilities of making defective items and machine breakdowns are a function of both the quantity (amount) and quality (performance) of the consumed setup cost (including the preventive maintenance cost). We further assume that the setup performance can be improved by investing in the performance improvement program. Hence, the same or a better setup outcome can be achieved with a lower setup cost. We then investigate the optimal setup cost and investment policy simultaneously, thereby achieving a better process quality and setup cost reduction concurrently.

  • The purpose of the study was to investigate the relationship among management strategic type, QR system adoption and the usage level of technologies. Also the current situation about the management strategies for the Korean apparel manufacturers was examined in this study. A random sample of 102 apparel manufacturers was selected for the data collection. A survey method was used with the structured questionnaire, and for the data analysis, chi-square test, ANOVA and Duncan's multiple range tests were used. The resets were as following: 1. The most identified strategic type among Korean apparel manufacturers was analyzer and the defender. 2. The most frequently used technologies were small lot orders and the reduction in the inventory level, and the least used technologies were the electronic order system and UPS. 3. The management strategic type was significantly related to the adoption and the usage level of technologies.
