This study describes how the weights of performance measures varies depending on business strategy types, such as defenders, prospectors, analyzers, and reactors. A Balanced Scorecard has been widely used for measuring a corporate performance to incorporate financial and non-financial measures simultaneously. Because such performance measurements are related to the compensation and promotion of employees, research of weights of performance measures would be instrumental. Our test results demonstrate that the weights of the business performance measures differ in the four perspectives-financial, customer, internal process, and learning and growth. Furthermore, there is evidence that the weights of performance measures vary depending on business strategy. Our study results can be used for enhancing the quality of performance measurement systems.

Selecting and implementing competitive strategies based on e-business is extremely important since it determines if an enterprise can continue to grow or not. Accordingly, systematic and empirical study on the implementation of e-business based on competitive strategy is required, and in-depth studies considering various e-business development stages of enterprises are also needed. The purpose of this study is to present guideline for the staff in charge and managers of enterprises to achieve competitive advantage and to increase organizational performance in e-business environments. What we have found are as follows. (1) Factors greatly influencing on competitive strategy selection through e-business were environmental uncertainty, centralization, innovative culture, technological competence, and formalization. (2) Results of the relationship between competitive strategies and e-business performance showed that each strategy had different effects on financial performance, process performance, and customer performance. and (3) Data analysis between internal and external environmental factors and competitive strategy by each e-business development stage proved that the relationships between competitive strategy and e-business performance were different based on e-business development stage. Implications of the study and guidelines for the managers are provided in the paper.

Dramatic increase of social concerns on the environments has led companies to take into account environmental issues in strategic decision-making. The strategic consideration on environmental management is essential to the modern companies. This study was initiated with a research purpose to explain the level and the characteristics of corporate environmental strategy through comparing the Hyundai, GM and Toyota Motor Company. The research method adopted by this research is a case analysis. The degree of environmental management strategy was evaluated in functional sectors or value chain including the production, research and development, procurement, logistic and recycling etc. Consequently, this study could find that Toyota is the most advanced company in the level of environmental management strategy. Also there are many differences among three companies in the level and degree of environmental management strategy. Hyundai and GM did not consider environmental management in foreign subsidiaries as much as Toyota. Motor Company. Also the study find out there are actual gaps between the rhetoric and reality in environmental management strategy in Hyundai Motor Co. All companies included in this study consider importantly ISO14001 as the tool to maintain the environmental management of their companies.

We draw on well-established thinking in the complementary fields of organization theory and strategic management to develop a model explaining why fit among a firm's competitive strategy, its structure, and its technology is a prerequisite for superior performance. The contributions of this theoretical treatise are twofold. Firstly, it helps reduce the disconnect in thinking that exists between the strategy and organization-theory literatures on business-level issues. Secondly, it reveals the importance of managing the coalignment among strategy, structure, and technology which, in turn, forces recognition that competitive advantage does not exist in a static state but in a dynamic condition.

A routing strategy based on traffic prediction and dynamic cache allocation for satellite nodes is proposed to address the issues of high propagation delay and overall delay of inter-satellite and satellite-to-ground links in low Earth orbit (LEO) satellite systems. The spatial and temporal correlations of satellite network traffic were analyzed, and the relevant traffic through the target satellite was extracted as raw input for traffic prediction. An improved gradient boosting regression tree algorithm was used for traffic prediction. Based on the traffic prediction results, a dynamic cache allocation routing strategy is proposed. The satellite nodes periodically monitor the traffic load on inter-satellite links (ISLs) and dynamically allocate cache resources for each ISL with neighboring nodes. Simulation results demonstrate that the proposed routing strategy effectively reduces packet loss rate and average end-to-end delay and improves the distribution of services across the entire network.

An impeller is a type of high-speed rotor that is used to compress or transfer fluid under high-speed and pressure at high temperatures. The impeller is composed of an axial hub and several blades attached along the hub. The weight and shape of an impeller must be balanced, because their imbalances can cause noise and vibration, which can lead to the breakage of the impeller blades during operation. Thus, the hub and blades of an impeller are commonly machined in a 5-axis NC machine to obtain qualified surfaces. The impeller machining strategy or process plan can not be easily obtained due to the complex, overlapped and twisted shapes of impeller blades. Skillful machining process planners may generate appropriate machining strategies based on their experiences and floor data. However, in practice most shop floor data for the impeller machining is not well-structured such that it does not effectively provide a process planner with information for machining strategies and/or process plans. This paper reports the development of a case-based machining strategy support system (CBMS) that employs case-based reasoning to obtain the machining strategy of an impeller by using the existing machining strategies of the shop floor. The CBMS generates impeller machining strategies through a stepwise reasoning process considering the similarity features between the blade shapes and machining regions. A case study is provided to demonstrate that CBMS can generate useful machining strategies facilitating process planners. The developed system can simulate the tool paths of impeller machining and runs on the web.
