Auto part industry supplies production for auto manufacturer and after market. These company have inventory for delivery. High inventory level can be good for delivery, but cost will be increase. Low inventory level can be customer unsatisfaction for delivery late. Low inventory level also is reason of low productivity by decreasing product batch size. These article suggest model for calculation a proper inventory level and prove a effect by simulation of some company.

다른 제조 업체에 부품을 공급하는 부품 기업에서는 고객 수요를 대응하기 위해 운 영하기 위해 완제품이나 반제품 재고를 운영하고 있다. 재고는 많으면 고객 대응도가 좋아질 수 있지만 운영 비용이 늘어나고, 재고가 너무 적으면 고객 대응이 지연되어 고객 불만족을 초래하게 될 것이다. 또한 재고 수준이 적으면 고객 수요에 대한 생산 회수가 증가하여 배치 생산으로 생산성을 높이는 것이 어렵게 된다. 따라서 고객 수요 대응에 대한 만족도를 최대한 유지하고 운영 비용이나 생산 비용을 절감시키는 방안 에 대해서 시뮬레이션을 통해 제시하고자 한다.

This study proposes a collaboration system framework on the web service in a supply chain to implement an efficient virtual supply chain and improve an ability to fulfill received orders over a supply chain. The system based on the framework proposed in this paper plays an important role for automatic order negotiation and placing/receiving an order noticed in web service by the main system. Furthermore, it can evaluate the fulfillment of received orders over a supply chain by using the transaction results from hierarchically related vendors and establish efficient manufacturing plans. In a word, this system is the automated system for creating manufacturing plans, placing and receiving orders. A little more important main function of this system is that it has a dynamic evaluation capability about fulfillment with received orders over a supply chain, and improves the evaluation method of fulfillment ability with received orders with related to direct dealing vendors, which is a main problem in existing system. As a result, this system is able to reduce the work load of the sales and purchasing materials, production control division, to manage accurate inventory promptly, to maintain the optimal inventory level by analyzing the information of fulfillment ability with received orders, and to enhance the level of service for customers.

This study tried to develop the system (device) that automatically notify a manager of condition just before and after farrowing to extend ubiquitous-based technology and to increase efficiency of delivery care and productivity by reducing human labor and time on standby when farrowing management is done in the difficult and hard working environment of farrowing such as night or holidays in field sand especially in pig industry. In this test, selected 10 gilts were executed timed artificial insemination and were set up each temperature sensor and load sensor to them 3 days before the estimated farrowing day and were observed the farrowing situation. This study was embodied the NESPOT-based (KT Corporation) monitoring system, the system to transmit data in real time by utilization of wireless LAN and the sensor module to apply the ubiquitous environment to them. And this study was observed the situation to automatically notify situations of 10 gilts that first bore just before and after farrowing. The result obtained the farrowing situations of them in real time by setup of the NESPOT-based monitoring system to check farrowing situation directly is as follow. The average time of the automatic notice about situation just before farrowing by the temperature sensor was 27.5 minutes before the beginning of farrowing (the expulsion time of a piglet). 6 of 8 pregnant gilts that first bore automatically were notified situations just before farrowing and the temperature sensors inserted into 2 ones before farrowing were omitted. (The automatic notice rate 75%) The average time of the automatic notice of situation just after farrowing by the load sensor was taken 46.5 minutes after the beginning of farrowing (the expulsion time of a first piglet). The average gestation period of 8 ones that first bore and were tested by the automatic notice of farrowing situation was 115.6 days. This result found that the automatic farrowing notice system by the temperature sensor is more efficient than the load sensor as the automatic farrowing alarm device and sanitary treatment and improvement of the omission rate were required.

Purpose - This paper empirically investigates the role of volatility in the China’s Renminbi (RMB) exchange rate plays on the Sino-Korea trade based on the analysis of auto industry. Due to the increasing proportion of China’s share in the world trade, RMB exchange rate is getting attention worldwide. Due to the close Sino-Korea trade relationships and the special position that auto industry plays in a country’s economy, this paper examines the causal relationship between RMB exchange rate volatility and Sino-Korea trade in this sector. Design/Methodology - Econometric methods including Johansen test of Co-integration, Granger causality analysis and multiple regression analysis are employed to explore the impact of RMB exchange rate changes on Sino-Korea bilateral trade flow using time series data of from 2001 to 2017. Findings – The outcome shows the real exchange rate changes of RMB have a limited effect on the improvement of Sino-Korea trade. The result indicates that there is a steady long-term relationship between bilateral real exchange rate of RMB and Sino-Korea trade. However, since the elasticity of exchange rate is too small, the change of exchange rate has a limited influence on Sino-Korea trade. In a short-run there is no lag on Sino-Korea trade processed by the real exchange rate. Originality/value - Neither theoretical studies nor argument analysis have reached a common conclusion on this point in the extant research. Even for the same country, the difference of industry, data and model they selected could result in the different results. Thus, this study is re-assessing the RMB’s exchange rate changes and Sino-Korea trade relationship by using the most recent and industry-level trade data. To examine the relationship this paper focuses on auto industry, the representative of the manufacturing industry in both countries.

Since 2008 the world financial crisis, implemented by the America government monetary payment policy has brought increased liquidity, but the decline in the dollar value of the decline of the export competitiveness of the countries all over the world, especially since 1980, Japan's economy is facing difficulties great, plus American monetary easing, the Japanese economy and more faded. Since 2012 October the Japanese far right parties, Liberal Democrat Andouble government came to power, the Japanese government yen devaluation, depreciation of the yen to Japanese economic recovery, but the Asian countries has been on the Japanese export oriented development mode, and the types of export commodities are more or less the same, therefore, the depreciation of the yen after Japan's exports have the great competitiveness, but at the same time the rest of Asia's export competitiveness has declined. The yen short-term the biggest damage country is South Korea, then China, but the total economic China than South Korea, namely the yen's depreciation on Chinese is very large, especially Chinese ships, iron and steel, auto parts and other heavy industry. Chinese are developing countries, the developing countries China heavy industry development is essential in its economic growth on the road, the developed countries of western countries and Japan have to rely on the development of heavy industry, heavy industry development level decides the development level of a country, RMB appreciation has lasted one and a half years, from a in the short term, has little effect on the Chinese economy. To observe effects of yen depreciation consequences, and through this thesis research the effect of the devaluation of the yen Chinese industry and explore the impact of future devaluation of the yen Chinese.
