Several studies have been completed on the topic of container terminals in Northern Vietnam. Few of them, however, deal with competition in terms of costs related to vessel waiting time or cargo handling. This paper estimates the average waiting cost per TEU for all the container terminals in Northern Vietnam. After average waiting time was first estimated by applying queuing theory, uncertainty theory was applied to estimated vessel daily cost. A simulation was performed to create a series of data representing waiting cost per TEU in relation to the rate of volume handled/capacity of each terminal. Non-linear regression based on this series was used to present a function for the relationship between the average waiting cost of each terminal and the rate of volume handled /capacity.

The strategic management process includes the establishment of competitive strategy, its implementation and the measurement of its performance. The sucess of strategic management largely depends on the integration of strategic management process into a managerial tool. This study is on the integration of strategic management process into a managerial tool based on the power process, so that it contributes to strategic success or sustainable competitive advantage of a ￡inn In order to do this, I discussed the principles of the power process, its characteristics, and then suggest their applications to the integration of the strategic management process. According to the results, the power process offers a theoretical and managerial tool which integrates the establishment of competitive strategy with managerial concepts, so that it increases the likelihood of strategic success. Furthermore I discussed the position of the power process approach to competitive advantage in a manner that displays similarities and differences with existing approaches such as industry organizational, resource-based and game theory approach.

The application of reinforcement design to ensure the structural safety of electronics in small satellites is limited by the spatial constraints of the satellite structure during launch vibrations. Additionally, a reliable evaluation approach is needed for mounting highly integrated devices that are susceptible to fatigue failure. Although the Steinberg fatigue failure theory has been used to assess the structural integrity of electronic devices, recent studies have highlighted its theoretical limitations. In this paper, we propose a structural methodology based on the critical strain theory to design the digital control unit (DCU) of the X-band SAR payload component for the small SAR technology experimental project (S-STEP), a small satellite constellation. To validate the design, we conducted modal and random analyses using simplified modeling techniques. Based on our methodology, we ultimately demonstrated the structural safety of the electronics through analysis results, safety margin derivation, and functional tests conducted both before and after the launch test.
