Performance management of computer networks is intended to improve a given network performance in order for more efficient information exchange between subsystems of an integrated large-scale system. Importance of perfomance management is growing as many functions of the large- scale system depend on the quality of communication services provided by the network. The role of performance management is to manipulate the adjustable protocol parameters on line so that the network can adapt itself to a dynamic environment. This can be divided into two subtasks : performance evaluation to find how changes in protocol parameters affect the network performance and decision making to determine the magnitude and direction of parameter adjustment. This paper is the first part of the two papers focusing on conceptual design, development, and evaluation of performance management for token bus networks. This paper specifically deals with the task of performance evaluation which utilizes the principle of perturbation analysis of discrete event dynamic systems. The developed algorithm can estimate the network performance under a perturbed protocol parameter setting from observations of the network operations under a nominal parameter setting.

Ministry of Land, Transportation and Maritime Affairs has implemented Construction CALS project for improving informationization level of construction industry and for making construction production system efficient. Although an importance of evaluation on level and performance of construction informationziation projects has been emerged, Construction CALS hasn't been evaluated so far. In this study, the performance indicators of construction CALS as the most important base in creating a performance management system were deduced. For this aim, this study reviewed the former researches on system construction for managing performance, analyzed current status of Construction CALS, arranged the relationship between upper strategies and ISP, developed pools of performance indicators, and this study followed IT BSC methodology. As a result, this study developed performance indicators of Construction CALS through four strategies such as globalization and activation of Construction CALS standards, research & development for reaching to international level in construction informationization technology, stabilization of system operation and distribution by publicizing Construction CALS and improving its functions, and policy implementation for managing and coordinating Construction CALS projects. These indicators will be applied to build a system of performance management.

The purpose of this study is to present that the strategic orientation affects on the green management performance. In order to carry out this research, the samples are reviewed and the ten hypotheses are verified reliably and appropriately. The results of the verification are summarized as follows: First, strategic directivity affects on the green management performance significantly. Second, two factors of the strategic directivity, customer orientation and technology orientation affect on the green performance relatively high. Finally, the two elements of the strategic orientation, competitive orientation and technology orientation affect on the financial performance significantly. In conclusion, this study shows all of the factors of the strategic orientation affect on the green management. In order to get the effective green management, education programs should be conducted by social support systems.

Recently, more firms have shown an interest in implementing knowledge management methods. However, few companies are capable of adopting knowledge management methods effectively to improve organizational performance because it is still unclear how these methods improve corporate performance. To find this relationship between knowledge management methods and organizational performance, this paper analyses effects of knowledge management methods on corporate performance empirically. 51 Korean firms are selected as a sample base for empirical tests. Knowledge management methods can be categorized into four styles; harmony, codification, personalization, and ignorance. For example, the emphasis of harmony style is on both knowledge reusability using information technologies and knowledge sharing through informal intimacy among employees. Corporate performance varies depending on styles. Harmony style is founded to be most effective for corporate performance. Personalization and codification styles don't show any difference. This outcome is in line with the general observation that both tacit knowledge and explicit knowledge are important for effective knowledge management.

Many companies have considered IT outsourcing as one of strategic alternatives in order to rapidly respond to changing business environment and strengthen their competitiveness. Despite its strategic role, however, IT outsourcing project has been plagued by a high failure rate and difficulty in realizing the promised project performance because of its inappropriate risk management. This study examines the effect of IT project management risk factors on project performance. We propose that project risk management factors(communication, technology sharing, and project control) influence project performance(process performance and product performance). Based on the empirical results, theoretical and practical implications of the study are discussed along with its limitations.

Supply chain performance management is the essential part of various business activities in supply chain management area, and integrating it with general business management improves the supply chain performance. Although supply chain performance management is important and expected of market growth, there are few researches on this area and lack of practical applications. To resolve these problems, this paper presents a new performance management methodology for a supply chain integrating SCOR (Supply Chain Operational Reference) model and Balanced Scorecard (BSC). And we develop a framework of the Supply Chain Performance Management System (SCPMS) based on this methodology, and implement a prototype system.

This study examined the relationship between determinant factors of FDI and management performance, and tested moderating effects by competitive strategy. Questionnaires were gathered from 113 respondents, but only 92 valid copies were analyzed through SPSS WIN 18.0. The major empirical results are as follows: In hypothesis 1, Firm-Special Advantage impacted on Management Performance strongly, Internal Advantage impacted on Management Performance strongly, and Locational Advantage impacted on Management Performance strongly. In Hypothesis 2, the moderating effects by competitive strategy on the relationship between determinant factors of FDI and management performance were tested through multiple regression. The result of the moderating effects by competitive strategy were found to be insignificant. Implications of the finding as well as the limitations of this study are also discussed.

After enterprise get a certification in acquisition, the core requirements of ISO/TS 16949 standard is pull out the Performance Indicators by process access approach during the settlement and operation of system, and the pulled key performance indicators classified into the customer intention process, support process and management process and analyzed the effect to the management result. This study conducted with following step. Firstly, preceding research, the literature and investigation analysis about process approach method which is the special characteristics of ISO/TS 16949 standard. Secondly, each process of ISO/TS 16949 standard is classified and deduced the key performance indicators followed process access method. Finally, get a enterprise survey data related to improvement of Performance Indicator and analyzed by SPSS statistical software.

This study aims to verify the structural correlation empirically between information security performance and information management performance. To verify the correlation, three factors such as managerial controlled activity, technical controlled activity, and physical controlled activity are divided for the information security activities variable. the security performance are divided into accident prevention and accident response variables. As a result, security organization activity is a unique factor being positively significant to information security and management performance. And three activities such as human security, security training, development security do not affect at all on both information security and management performance.
