The problem considered here is to find the optimal discriminant analysis method in growth curve model. It has been studied how to find correct prior probability for the effective classification in discriminant analysis. We use the balanced condition to calculate prior probability. From the informative simulation study, new classification rule for the growth curve model is suggested. The suggested classification rule has better classification result than the other previously suggested method in terms of error rate criterion.

This study aims to suggest a performance measurement model reflecting the characteristics of safety evaluation system, especially the model for return manufacturing related to safety, and to develop the S-BSC(Safety-Balanced ScoreCard) measurement model using a weight lifetime value to which a relative weight is applied by using AHP based on the BSC.

The main purpose of the present study are as follows: First, through the extensive literature review, we tried to find out environmental changes in the management thoughts. Second, as we found a new paradigm on valuation-oriented management thoughts, we argued that cost/management accounting information should play key roles in creating values. Third, we pointed out that when firms used only financial performance measurements, problems could take places. Finally, especially to promote the organizational effectiveness and efficiency, we stressed that firms should use the balanced scorecard approach in performance measurements of its own organizations and personnels.

급속한 경영환경의 변화는 기업의 포지션과, 장기적인 개발 기획등에 초점을 맞추던 전통적인 기획과는 다른 전략 경영 기법을 요구하고 있다. 경영환경의 변화는 전략의 실행 과정을 운영/통제 모드에서 변화 유도 모드로 변환시키고 있기 때문이다. (중략)

During the last decade many enterprises spent a huge amount of money for investment on Information Technology (IT) & Information System (IS) to attain competitive advantage and to maximize their business performance by satisfying the various requirements of customers. Under such circumstances, methodologies for evaluating IT impact on business performance are very important issues for strategic decision making on investment. In this study, we propose a performance evaluation model that adopts the concept of the Balanced Scorecard (BSC) and the Value Chain to analyze the financial impact and non-financial impact of IT & IS at each critical work area. This model combines the 4 evaluation areas from BSC and 6 critical work areas from Value Chain and measures the Key Performance Indicator (HPI) and the effect of KPI. Also, we present a case study of which the evaluation model has been conducted on a major manufacturing company. finally. we address some important notes to improve the IT & IS performances in the real-world.

The smoke exhaust system is one of the effective systems to save lives when fire occurs underground. This study presents a complete analysis of effective smoke exhaust and smoke characteristics for a fire occurring with a transverse ventilation system use as a smoke exhaust system. The performance of the smoke management system was studied by computer modeling using FDS version 3.1. A fire size of 20MW was used for tunnel with balanced exhaust transverse ventilation. The smoke management design and the procedure as simulated in this study are also compliant to the tunnel construction and fire codes of Korea.

In a very competitive construction business environment there is a need to measure and manage business performance across a wider spectrum of business success criteria. The Balanced Scorecard (BSC) and Triple Bottom Line (TBL) reporting concepts are emerging as champions in the race for sustainable business success. The construction business organisations are often judged based on their financial performance as well as wider performance. This paper aims at developing a universally accepted tool for assessing contractors' wider business performance in the construction industry. A prototype of web-based business performance measurement system has been developed to help contractors assess their own performance aimed at uplifting their performance. The consultants/clients can also use the tool to measure contractors' performance in a value-based contractor selection. The system was developed based on the research conducted among 63 senior construction professionals and therefore further research with the participation of a large number of managers across different countries and also an upgrade of the system will be required.

Management of social infrastructure has been advanced from facility management (FM) to asset management (AM), which adopts the aggressive and proactive methods in predicting the deterioration of infrastructure, prevents failures, and eventually saves maintenance cost. Infrastructure asset management is not a simple engineering technique, but it is a new paradigm evolved from facility management practices. To implement the infrastructure asset management successfully, organizational reform is very important. This paper suggests critical success factors and key performance indicators to implement the infrastructure asset management for facility managers of government owned social infrastructures such as roads and bridges. Reorganizing the facility management group requires new vision, objectives, strategies for the paradigm-changing asset management. This paper uses Balanced Score Card (BSC) which is a proven method in measuring and setting new objectives for an organization. Once the performance indicators are reviewed repeatedly by facility managers through experts workshops, developed BSC can be used in practice. This paper discusses the development of robust BSC scoring method through in depth literature reviews and investigation of asset management practices of domestic and international cases.

Evaluation of the implementation and performance of a firm's green supply chain management (GSCM) is an ongoing process. Balanced scorecard is a multi-criteria evaluation concept that highlights implementation and performance measures. The literature on the framework is abundant literature but scarce on how to build a hierarchical framework under uncertainty with dependence relations. Hence, this study proposes a hybrid approach, which includes applied interpretive structural modeling to build a hierarchical structure and uses the analytic network process to analyze the dependence relations. Additionally, this study applies the fuzzy set theory to determine linguistic preferences. Twenty dependence criteria are evaluated for a GSCM implemented firm in Taiwan. The result shows that the financial aspect and life cycle assessment are the most important performance and weighted criteria.
