The objective of this paper is to analyze the competitiveness of the Cargo Management improvement of FTZ(Free Trade Zone) in East Asia and to suggest several measures to improve it. To the end, various comparisons are made between the FTZ of Incehon and those in Hongkong, Taiwan, Shanghai. Competitive advantages of Incheon's FTZ over others lie in its better contiguity, frequency, quality service, and convenient connections associated with the airport. To be viable, however, the Incheon's FTZ needs to have strong supports from the central government such as more SOC investment, early introduction of RFID/UBIQUITOUS, improvement of customs process and logistics system, and competitive incentives to bring in more international channel hubs to this area. With these implemented promptly as suggested, the Incheon's FTZ will draw its competitive advantages over those in Taiwan and Shanghai and will play an vital role to bring in more MNEs to Korea.

Purpose: As one of the most developed cities in China, the application of e-commerce is more mature, especially the promotion of ecommerce to foreign trade. After the establishment of Shanghai Free Trade Zone (FTZ) in 2013, the government issued a series of policies to promote the application of e-commerce in Shanghai's foreign trade. This paper takes Shanghai FTZ as an example to study how to develop the application of e-commerce in other free trade zones and how to innovate the international trade mode. Research design, data and methodology: This paper selects the latest data from 2010 to 2019, uses econometric correlation analysis and regression analysis to study the impact of e-commerce on the foreign trade of Shanghai FTZ. Results: At last, the conclusion is drawn that the establishment of free trade zone provides many advantages for the development of e-commerce in Shanghai, and the growth of e-commerce in Shanghai FTZ promotes the development of foreign trade of Shanghai FTZ. Conclusions: So as to promote the development of e-commerce in Shanghai Free Trade Zone, some suggestions are put forward, such as increasing network supervision, establishing e-commerce talent training system, logistics management and information management systematization.

In the design of production system, buffer capacity allocation is a major step. Through polymorphism analysis of production capacity and production capability, this paper investigates a buffer allocation optimization problem aiming at the multi-stage production line including unreliable machines, which is concerned with maximizing the system theoretical production rate and minimizing the system state entropy for a certain amount of buffers simultaneously. Stochastic process analysis is employed to establish Markov models for repairable modular machines. Considering the complex structure, an improved vector UGF (Universal Generating Function) technique and composition operators are introduced to construct the system model. Then the measures to assess the system's multi-state reliability and structural complexity are given. Based on system theoretical production rate and system state entropy, mathematical model for buffer capacity optimization is built and optimized by a specific genetic algorithm. The feasibility and effectiveness of the proposed method is verified by an application of an engine head production line.

A power-saving mechanism for smartphone devices is developed by analyzing the features of data that are received from Internet of Things (IoT) sensors devices to optimize the data processing policies. In the proposed GreenIoT architecture for power-saving in IoT, the power saving and feedback mechanism are implemented in the IoT middleware. When the GreenIoT application in the power-saving IoT architecture is launched, IoT devices collect the sensor data and send them to the middleware. After the scanning module in the IoT middleware has received the data, the data are analyzed by a feature evaluation module and a threshold analysis module. Based on the analytical results, the policy decision module processes the data in the device or in the cloud computing environment. The feedback mechanism then records the power consumed and, based on the history of these records, dynamically adjusts the threshold value to increase accuracy. Two smart living applications, a biomedical application and a smart building application, are proposed. Comparisons of data processed in the cloud computing environment show that the power-saving mechanism with IoT architecture reduces the power consumed by these applications by 24% and 9.2%.
